The through-line

This eleven-episode series argues that intestinal failure in children is no longer a death sentence but a manageable chronic condition—provided the surgical, medical, and nutritional decisions made in the first hours and months are guided by an understanding of intestinal biology rather than visual assessment at laparotomy [e2p1-c23]. The series builds a case for conservative early management, aggressive enteral feeding, multidisciplinary coordination, and patience with the adaptive process [e1-c3]. Survival in major programs now exceeds 90%, and fewer than 2% of patients die from liver disease, yet the path from neonatal catastrophe to enteral autonomy depends on clinicians resisting the impulse to resect aggressively, predict outcomes prematurely, or intervene surgically without understanding what the next three operations will require [e2p2-c3][e4p1-c4].

The progression: from acute crisis to chronic optimization

Episodes 1–2: The foundational argument. The series opens by defining intestinal failure and rehabilitation as a coordinated, time-dependent process requiring enteral nutrition and measured in months to years [e1-c1][e3p1-c2]. Episode 2 immediately confronts the highest-stakes decision: what to do when a preterm infant's bowel appears dead at laparotomy. The answer—clinical observation over visual prediction—sets the tone for the entire series [e2p1-c24]. Helmrath introduces the 50% rule: focal necrosis under 50% of bowel length warrants resection for good adaptive potential, but diffuse necrosis over 50% demands proximal decompression and time [e2p1-c1][e2p1-c14]. The mechanism is liver protection through duodenal decompression, not salvage of questionable bowel [e2p1-c8]. Part 2 extends this to outcomes: ultra-short gut survival is 90–95%, and patients with remnant ileum or colon adapt better than expected [e2p2-c3][e2p2-c7]. The critical teaching is that the 30-week preterm gut has profound regenerative capacity if given luminal nutrition during the steepest growth period—35 weeks gestation to 6 months postnatal [e2p2-c4][e3p1-c23].

Episodes 3–4: The biology and mechanics of adaptation. Episode 3 shifts from crisis to biology. Adaptation is structural (mucosal hypertrophy, angiogenesis, bowel dilation) and functional (slowed motility, upregulated transporters), driven by intraluminal nutrients interacting with trophic peptides [e3p1-c3][e3p1-c4][e3p1-c5]. The ileum adapts better than jejunum because it produces GLP-2, GLP-1, and PYY, which slow motility and signal the liver [e3p1-c8][e3p1-c21]. The colon becomes critical when small bowel remnant falls below 50% of expected length, providing energy from short-chain fatty acids [e3p1-c27]. The new definition of enteral autonomy—independence from parenteral support for 12 weeks with adequate growth and hydration—reframes success around the child's biology, not the calendar [e3p1-c15][e3p2-c23]. Episode 4 translates this into surgical strategy. The STEP procedure works not by creating new bowel but by tapering dilated segments to restore motility [e4p1-c8][e4p2-c1]. Absorptive capacity improves over six months as inflamed mucosa heals [e4p2-c5]. The technical details matter—perpendicular staple lines, 2–2.5 cm caliber, crotch sutures, avoidance of duodenal stapling—but the philosophy matters more: surgery is a game of chess requiring planning two and three steps ahead, and the first operation in the first week of life has lifelong consequences [e4p1-c4][e4p2-c30].

Episode 5: Pharmacologic augmentation. The literature review on teduglutide introduces the only FDA-approved trophic peptide for children. At 0.05 mg/kg, 69% of patients achieved 20% TPN reduction and 10% discontinued TPN entirely [e5-c8][e5-c9]. The mechanism—improved fluid and electrolyte management at the epithelial layer despite GLP-2 receptors not being on enterocytes—underscores that adaptation is a systems problem, not a local one [e5-c17][e5-c18]. The drug requires enteral stimulation to work; the light switch is feeding, the dimmer is the hormone [e5-c13]. This episode also surfaces a recurring theme: fluid management, not calorie absorption, is often the limiting factor in weaning TPN [e5-c15][e5-c20].

Episodes 6–8: Managing complications and the long game. Episode 6 addresses cholestasis, historically a 25–50% mortality driver, now under 2% [e6-c5]. The shift reflects better lipid management (SMOF allows conventional dosing with hepatoprotection), aggressive enteral feeding, and recognition that a bilirubin of 2 mg/dL is transient and does not warrant intervention [e6-c11][e6-c14][e6-c18]. The teaching moment: after jejunostomy takedown, bilirubin and liver enzymes rise transiently as enterohepatic circulation resumes—this is normal, not failure [e6-c19][e6-c20]. Episodes 7 and 8 tackle refeeding in neonates and older children. The neonatal strategy is counterintuitive: high stoma output is an indication to feed, not withhold feeds, because damaged bowel transitions from secretory to absorptive phase only with luminal nutrition [e7-c2][e7-c3]. Breast milk is ideal, but the common mistake is isocaloric TPN reduction when advancing enteral feeds—children with sick intestines do not absorb all calories provided, and total volume may need to expand beyond 140 mL/kg [e7-c10][e7-c13]. For older children who lose bowel to volvulus, the challenge is maintaining nutrition through puberty when energy demands spike; some require temporary return to parenteral support, but marginal gut function often suffices once growth is complete [e8-c21][e8-c22][e8-c24].

The synthesis: what emerges from the whole

Three themes recur across the series, each building on the last. First, time is the variable clinicians control. The gut doubles in length between 35 weeks gestation and one year, and motility matures only with enteral feeding [e4p1-c5][e4p1-c6]. Surgical decisions that preserve bowel length and enable early feeding during this window determine whether a child reaches autonomy [e3p1-c32]. Second, the liver is the gatekeeper. Cholestasis, once a death sentence, is now a manageable complication, but only if duodenal decompression is achieved and enteral feeding is prioritized [e6-c21][e6-c9]. Third, motility trumps length. Very short bowel patients with excellent peristalsis can come off TPN; longer bowel with poor motility cannot [e4p1-c10]. This is why gastroschisis patients underperform despite adequate length—the enteric nervous system is damaged—and why NEC patients do better than expected—they were fed before injury, initiating motility [e4p1-c16][e4p1-c20].

The series also tracks an evolution in surgical philosophy. Early episodes emphasize what not to do: do not resect based on visual assessment, do not create stomas that lose abdominal domain, do not perform STEP in the first year if motility has not matured [e2p1-c23][e2p1-c18][e4p1-c19]. Later episodes shift to what to do: place a G-tube at the first operation for feeding versatility, use Blake drains for proximal decompression, plan staged procedures rather than attempting comprehensive repair [e7-c29][e2p1-c23][e4p2-c9]. The unifying principle is that intraoperative decisions have lifelong impact, and the surgeon's role is not to be the hero but to set up the next operation [e4p2-c30][e4p2-c29].

What the series does not cover

The series is silent on intestinal transplantation beyond acknowledging it as part of the continuum of care [e2p1-c2]. It does not address the psychosocial burden on families managing home TPN, central line care, or the transition to adult care. Neurocognitive outcomes are mentioned optimistically—most children are "running and playing"—but the series does not quantify deficits or explore educational support needs [e2p2-c12]. The role of the microbiome is acknowledged (shifts to acid-producing flora, bacterial overgrowth as a driver of staple-line ulcers) but not deeply explored [e3p1-c28][e4p2-c12]. Finally, the series does not grapple with resource disparities: the multidisciplinary model described requires subspecialty access, home nursing, and insurance coverage that many families lack.

The argument the series makes

Intestinal failure is a chronic disease of childhood, not an acute surgical problem. The first four months of life are when care is most uncoordinated and surgical decisions most consequential [e4p1-c4]. Success requires resisting the impulse to do everything at the first operation, trusting the regenerative capacity of the neonatal gut, feeding early and aggressively despite high output, protecting the liver through duodenal decompression, and planning surgeries in sequence rather than isolation. The outcome—over 90% survival, 60–80% enteral autonomy, normal growth in most—is achievable, but only if clinicians allow the child's clinical trajectory, not their visual assessment or institutional tradition, to guide care [e3p1-c19][e2p1-c24].

Intestinal Rehabilitation in Older Children: Managing Life After Catastrophic Bowel Loss

The episode's main topic retold as a plain-language walkthrough — what it is, why it matters, and what the speakers concluded. Written by Kai from the episode transcript and reviewed before publishing.

For the care team · Explainer · AI-written, human-reviewed

Why This Exists

Intestinal rehabilitation emerged as a discipline because children who lose most of their bowel—whether to volvulus, necrotizing enterocolitis, or other catastrophic events—face a fundamentally different problem than simple malnutrition. They must learn to sustain life on a remnant gut that cannot absorb enough to meet metabolic demand. In neonates this is a problem of first establishing feeding behavior. In older children who lose 90+% of their bowel after years of normal eating, the challenge is relearning how to eat within the constraints of what remains 1:11. The benefit and curse: they know how to eat, but must now unlearn nearly everything about how they did it 1:24. For this population, feeding is not only about calories—it carries social weight that shapes quality of life 1:30.

The Core Problem

Short bowel syndrome in older children creates three interlocking deficits: inadequate absorptive surface for macronutrients, inability to maintain hydration, and loss of the metabolic reserve needed to sustain growth through puberty. The goal is not always independence from parenteral nutrition. When that is unachievable, the goal becomes optimizing quality of life within the constraints of chronic TPN dependence 1:50.

How the Approach Works

Dietary Reconstruction

The strategy inverts normal dietary advice. Push protein and fat, which are well tolerated 2:14. Minimize simple sugars, which most short bowel patients tolerate poorly 2:21. The mechanism: solids with minimal fluid reduce dumping 2:25. The practical structure: smaller meals, more frequently, with solids separated from liquids 2:31. This is not a temporary refeeding protocol—it is the permanent dietary architecture for someone living on remnant bowel.

Compliance erodes over time. Patients who successfully transition off TPN often drift back into trouble when diet history reveals they have relaxed these restrictions 2:52. The usual culprit: increased sugar intake, which disrupts absorption and increases stool output 3:12. Beyond the osmotic effect, minimizing sugars reduces bacterial overgrowth symptoms—bloating and gas that make eating intolerable 3:31.

Fluid Management

Fluid losses—whether from stoma or stool—must be replaced 3:48. If the patient remains on IV support, some replacement can be intravenous 3:56. The challenge intensifies when weaning off parenteral nutrition: hydration must now come enterally 4:01. This is not a matter of drinking more water. Fluid transport across the gut requires both sodium and glucose 4:11. Sports drinks fail because they contain too much sugar 4:48.

Some patients can discontinue TPN but still require a central line for IV fluids 4:55. Without adequate hydration they sleep most of the day and lack energy 4:55. Hydration status directly affects bowel function—a dehydrated gut does not work well 5:08. When oral intake is insufficient, rehydration solution can be delivered overnight via gastrostomy tube 5:31. The route matters less than the composition and the total volume.

The Puberty Crisis

Energy demands increase dramatically during puberty 5:51. Children who were stable often decompensate when pubertal growth begins, because energy needs outstrip what the remnant bowel can absorb 5:51. Some require return to parenteral support to get through this period 6:28. Once linear growth is complete, marginal gut function that was insufficient during adolescence often suffices in adulthood 6:33. The implication: anticipate this. Do not wait for growth to falter.

Very few intestinal failure conditions carry intrinsic growth restriction 6:57. A child tracking at the 3rd percentile should not be accepted as adequate 6:57. After weaning from TPN, micronutrient deficiencies become the next threat to growth 7:22.

Growth Monitoring

Weight alone is insufficient. It must be balanced against height 8:51. This population commonly produces "round babies"—children with elevated weight-for-height ratios 8:57. Emerging data examines quality of weight: fat mass versus lean body mass 9:01. For any child not meeting growth potential, the differential is broad: endocrine disorders, pancreatic insufficiency, micronutrient deficiencies 9:34. After addressing the identified issue, improvement should be evident within weeks, not months 9:54. Growth can be monitored remotely—do not wait until the next clinic visit 10:15.

When to Involve This Team

Any child with short bowel syndrome requires intestinal rehabilitation expertise, but the trigger for urgent involvement is growth faltering in a patient previously stable off parenteral support. The second trigger: an older child or adolescent approaching puberty who is marginal on enteral nutrition alone. The third: any patient on chronic TPN being considered for weaning. These are not problems for general gastroenterology—they require teams fluent in the interplay between gut function, parenteral support, growth dynamics, and the long-term complications of both the disease and its treatment.

The discussion did not address specific referral criteria or timing beyond the clinical scenarios described above.

For the care team · Teaching arc · AI-written, human-reviewed

An adolescent who loses most of their bowel to volvulus presents a different challenge than a neonate who never established oral feeding. The older patient knows how to eat — that established behavior is both advantage and liability 1:24. The work is not teaching them to swallow but managing what their remnant bowel can tolerate while preserving the social and psychological dimensions of eating 1:30.

Macronutrient selection over volume

The foundational principle: push protein and fat, which short bowel patients tolerate well, and minimize simple sugars 2:14 2:21. Most of these patients dump when given carbohydrate loads. The practical translation is smaller meals more frequently, solids separated from liquids, and deliberate avoidance of sugar 2:31. This is not a temporary restriction during early adaptation — it is the long-term diet architecture. Patients who drift back toward normal adolescent eating patterns (soda, juice, processed snacks) reliably present months later with increased stool output, bloating, and bacterial overgrowth symptoms 2:52 3:12 3:31. When an off-TPN patient decompensates, the diet history often reveals the problem before any lab does.

Hydration as the rate-limiting step

Fluid losses must be replaced 3:48. If the patient remains on parenteral support, some replacement can be IV 3:56. The harder problem emerges during TPN wean: keeping them hydrated enterally becomes the constraint on whether they can stay off central nutrition 4:01. Effective oral rehydration requires both sodium and glucose because fluid transport across the gut depends on coupled sodium-glucose cotransport 4:11. Gatorade fails because it contains too much sugar relative to sodium 4:48. Some patients can eliminate TPN but still require a central line for IV fluids — without adequate hydration they sleep most of the day and lack energy to function 4:55 4:55. Hydration status directly determines how well the remnant bowel performs 5:08. If a patient cannot tolerate drinking rehydration solution, delivering it via G-tube often works 5:31.

Puberty as the stress test

Energy demands increase dramatically during puberty 5:51. Children who were stable on marginal gut function often decompensate when pubertal growth begins because nutrient input no longer matches energy expenditure 5:51. Some require return to parenteral support to get through this growth phase 6:28. Once linear growth is complete, the same borderline intestinal function that failed during puberty often suffices in adulthood 6:33. This is not failure of the rehabilitation strategy — it is recognition that the metabolic demand of adolescent growth may temporarily exceed what a short gut can deliver.

Growth potential is not negotiable

Very few intestinal failure conditions carry intrinsic growth restriction 6:57. A child tracking at the 3rd percentile should not be accepted as adequate 6:57. When growth falters, the differential includes endocrine disorders, pancreatic insufficiency, and micronutrient deficiencies — not just inadequate calories 9:34. After addressing the identified problem, improvement should be evident within weeks, not months 9:54. Growth monitoring can be done remotely and should not wait for the next clinic visit 10:15.

Weight quality, not just weight

Weight must be interpreted in the context of height 8:51. This population commonly produces "round babies" with elevated weight-for-height ratios 8:57. Increasing data examine body composition — distinguishing fat mass from lean body mass 9:01. A child can be heavy and still malnourished if the weight is disproportionately adipose tissue rather than muscle.

The discussants returned repeatedly to one point: even if you cannot wean a patient off TPN entirely, compromises should be made to optimize quality of life 1:50. For an adolescent, that means preserving the ability to eat socially, maintaining hydration adequate for normal energy levels, and achieving growth that places them within normal range for their peers. The goal is not perfect intestinal function — it is the best life this gut can support.

Macronutrient Selection Drives Tolerance

The core feeding strategy is macronutrient-driven, not calorie-driven. Push protein and fat modules aggressively — these are well tolerated in short bowel syndrome 2:14. Simple sugars are the enemy: most short bowel patients tolerate them poorly 2:21, and their restriction reduces not just dumping but also bacterial overgrowth symptoms like bloating and gas 3:31. The meal architecture matters as much as the content: smaller meals more frequently, solids separated from liquids, and minimization of simple sugars 2:31. Pushing solids while minimizing fluid intake reduces dumping 2:25. This is not theoretical — patients who have successfully weaned off TPN often return with problems when diet history reveals they have relaxed these restrictions 2:52, with increased sugar intake creating absorption problems and changes in stool output 3:12.

Oral rehydration is a technical problem, not a compliance problem. Fluid losses must be replaced whether by stoma or other source 3:48. If patients remain on IV support, some replacement can be intravenous 3:56, but as you wean parenteral support, maintaining hydration through enteral replacements becomes critical 4:01. The composition is non-negotiable: fluid transport requires both sodium and glucose, so replacement solutions must contain both 4:11. Gatorade fails because it contains too much sugar 4:48. Some patients can discontinue TPN but still require a central line for IV fluids 4:55 — without adequate hydration they sleep most of the day and lack energy 4:55. Hydration state is fundamental to bowel function 5:08. When patients cannot drink rehydration solution, the GI tract can still use it via G-tube 5:31.

Puberty is the Stress Test of Marginal Gut Function

Energy demands increase dramatically during puberty 5:51, and children who were stable often decompensate when puberty begins because energy needs exceed nutrient input 5:51. This is predictable, not failure. Some patients require return to parenteral support to get through puberty 6:28. The calculus changes after growth is complete: borderline or marginal gut function that could not sustain an adolescent is often sufficient for an adult 6:33. The implication is clear — be proactive about supplementation during the pubertal window rather than reactive to growth failure.

Growth Failure is a Diagnostic Challenge, Not an Acceptance

A 3rd percentile growth trajectory should not be accepted for intestinal failure patients 6:57. Very few intestinal failure conditions carry intrinsic growth restriction 6:57. Poor growth demands investigation: endocrine issues, pancreatic insufficiency, and micronutrient deficiencies must all be considered 9:34. After addressing identified issues, improvements should be evident within weeks, not months 9:54. Growth monitoring can be done remotely and should not wait until the next appointment 10:15.

Weight alone is an inadequate metric. Weight must be balanced against height 8:51 — this population commonly shows "round babies" where weight-for-height is elevated 8:57. Increasing data examines quality of weight: how much is fat weight versus lean body mass 9:01. The distinction matters because adequate weight with poor linear growth and excess adiposity is not success.

Micronutrient Surveillance After TPN Discontinuation

After weaning TPN, patients commonly develop micronutrient deficiencies 7:22. The focus shifts from macronutrient delivery to micronutrient surveillance. Even if a patient cannot be cured and weaned completely off TPN, compromises should optimize quality of life 1:50. In older children, normal feeding behavior serves social functions beyond nutrition 1:30. The fact that older patients who lose their bowel after establishing eating behavior already know how to eat is both benefit and curse 1:24 — they have the motor pattern but must relearn what their remnant bowel can handle.

The discussants emphasized that older children who experience volvulus can lose more than 90% of their bowel 1:11, yet with disciplined feeding strategy, attention to hydration, anticipation of pubertal demands, and refusal to accept poor growth, many can achieve functional independence.

Takeaways from this story

Push protein and fat; restrict simple sugars to reduce dumping and bacterial overgrowth symptoms in short bowel patients
Oral rehydration requires both sodium and glucose; Gatorade fails because it contains too much sugar for effective transport
Energy demands spike during puberty — previously stable patients often need temporary return to parenteral support through growth
3rd percentile growth is unacceptable; very few intestinal failure conditions have intrinsic growth restriction
After TPN discontinuation, micronutrient deficiencies become the primary surveillance target

Refeeding Strategy in Older Children with Catastrophic Bowel Loss

The episode's teaching points arranged as a structured lesson, building from the basics up to the finer points. Written by Kai from the episode transcript and reviewed before publishing.

For trainees · Teaching arc · AI-written, human-reviewed

An eight-year-old who loses 90% of their bowel to volvulus presents a different rehabilitation challenge than a neonate with short bowel syndrome. The older child already knows how to eat — which is both advantage and burden 1:24. The goal shifts: you are not just delivering calories, you are preserving the social architecture of meals while managing a gut that cannot handle what the child remembers eating.

Macronutrient selection over volume

The general strategy is to push macronutrient modules of protein and fat, which are well tolerated 2:14. Most short bowel patients don't tolerate simple sugars very well 2:21. Pushing solids and minimizing fluid intake helps reduce dumping 2:25. The prescription is smaller meals more frequently, solids separated from liquids, and minimization of simple sugars 2:31. This is not a temporary restriction — patients who have transitioned off TPN often come back with problems when diet history reveals they have gotten loose with diet choices 2:52. The increase in sugars creates problems with absorption and changes in stool output 3:12. Minimizing sugars also reduces symptoms related to bacterial overgrowth such as bloating and gas 3:31.

Hydration as a distinct problem

Fluid losses whether by stoma or other source must be replaced 3:48. If patients are on IV support, some fluid can be replaced intravenously 3:56. When trying to wean off IV support, keeping patients hydrated through enteral replacements is important 4:01. Fluid transport requires sodium and glucose, so replacement solution must contain both 4:11. Gatorade doesn't work well for rehydration because it has too much sugar 4:48. Some patients can come off TPN but still need a central line for IV fluids 4:55 — without adequate IV fluids, patients end up sleeping most of the day and don't have energy 4:55. Being in a hydrated state is extremely important to making the bowel work well 5:08. Sometimes patients can't drink rehydration solution but the GI tract can use it via G-tube 5:31.

Puberty as a predictable crisis

Energy use goes up dramatically during puberty 5:51. Children doing well often hit the wall when they start puberty because energy needs overcome nutrient input 5:51. Some kids end up back on parenteral support to get through puberty 6:28. When not growing anymore as an adult, borderline or marginal gut function is often enough to sustain them 6:33. There are very few conditions with intestinal failure that have restricted growth 6:57. A 3rd percentile growth should not be accepted for most intestinal failure patients 6:57. After getting off TPN, patients often get into trouble with micronutrient deficiencies 7:22.

Growth metrics beyond weight

Weight must be balanced with height as a growth metric 8:51. This population commonly shows round babies where weight for height is elevated 8:57. There is increasing data looking at quality of weight — how much is fat weight versus lean body mass 9:01. For any child not meeting growth potential, numerous other diagnoses must be considered including endocrine issues, pancreatic insufficiency, and micronutrient deficiencies 9:34. After addressing growth issues, improvements should be assessed on the order of weeks not months 9:54. Growth monitoring can be done remotely and should not wait until the next appointment 10:15.

The central teaching is that older children with short bowel syndrome can achieve normal growth if you separate the problems — diet composition, hydration, pubertal energy demands, and micronutrient surveillance — and address each with the intensity it requires. The child who remembers eating normally deserves a plan that gets them as close to that as their remaining bowel allows.

Takeaways from this story

Simple sugars cause both dumping and bacterial overgrowth symptoms — diet liberalization after TPN wean often explains clinical deterioration
Effective oral rehydration requires both sodium and glucose; sports drinks contain too much sugar to work well
Puberty predictably destabilizes previously stable patients — some require temporary return to parenteral support until growth completes
Most intestinal failure conditions do not restrict growth potential — accept nothing below normal range without investigating correctable causes
Weight-for-height and body composition matter more than weight alone — this population tends toward elevated fat mass with inadequate lean mass

Topic overview

A clinical discussion on refeeding strategies for older pediatric patients (ages 8-16) with short bowel syndrome following catastrophic bowel loss. The speakers emphasize dietary management prioritizing solid foods over simple sugars, fluid replacement strategies using oral rehydration solutions, and the challenge of maintaining nutrition through puberty when energy demands increase. They stress that most intestinal failure patients are capable of normal growth and require multidisciplinary monitoring of both weight and height to avoid disproportionate fat gain without linear growth.

Key takeaways

Push protein/fat solids with minimal simple sugars; separate meals from liquids to reduce dumping in short bowel patients (2:14)
Oral rehydration requires both sodium and glucose; Gatorade fails due to excess sugar without adequate sodium (4:11)
Energy demands spike at puberty; patients stable pre-puberty may need temporary return to parenteral support (5:51)
Monitor weight-for-height, not weight alone; this population prone to disproportionate fat gain without linear growth (8:51)
Most intestinal failure patients capable of normal growth; 3rd percentile should not be accepted without investigating causes (6:57)

Hello everyone. Welcome back to the Stay Current podcast. I'm Cecilia Gigena from Cincinnati Children's Hospital, and along with Stay Current, we are sharing knowledge to improve child health around the globe. Today we have another episode of the intestinal rehabilitation podcast, and as always, we have Doctor Paul Wales, the current director of the intestinal rehabilitation Program at Cincinnati Children's Hospital. I'm Paul Wales. I'm a pediatric surgeon here at Cincinnati Children's Hospital, and Doctor Michael Helmrad. The prior director of the intestinal rehabilitation program. I'm Michael Helmrath. I'm a pediatric surgeon also doing intestinal failure surgery and research here at Cincinnati Children's. Today we have the 8th episode of the intestinal rehabilitation podcast, and we are going to talk about refeeding in an older patient. If you want to know how to refeed a neonatal patient, go back to episode 7 where you can find everything you need to know about that. So now let's start. Like the recent slew of kids we have that are between 8 and 16 that were eating just fine, and one day boom, they had a volvulus and they've lost 90+% of the bowel. The benefit in the curse in a patient like that is that they do know how to eat. They've established that that behavior. We know that enteral feeding is really. Important for nutrition, but in older children that is not the only main thing we get out of feeding because the normal feeding behavior is important in many social aspects of life. That is why it's very important to take this into consideration when we are treating older patients. So even if you can't cure this patient and get them off TPN. It's important to make compromises to optimize quality of life the best you can. Perfect. So let's talk about how to restart oral sleeping. We want to try to mimic the most normal seeding behavior that we possibly can. I still prefer. Letting them eat by mouth orally. The general strategy is you want to push the macronutrient modules of protein and fat are well tolerated. Most of these kids don't tolerate simple sugars very well. So the general concept of pushing solids. And minimizing fluid intake helps. They don't tend to dump as much smaller meals more frequently of solids separated from their liquids to a certain extent, and minimization of simple sugars. Understood. So reduce simple sugars and make smaller meals and try to separate them from liquids. Eventually they'll be able to tolerate more and more, but we'll see a lot of these patients that have transitioned off of TPN and truly fed, and then they come back having some problems later, and you find out when you take a close diet history that they've sort of fallen off the wagon a little bit, and they've gotten a little bit loose when it comes to some of the diet choices. And something important they highlight is to be very careful with the diet because the increase in sugars can create some problems with the absorption and changes in the stool. So if you encounter a patient that comes with high stool output, you will probably want to see how it's diet change. And not only that, but also sort of symptoms related to bacterial overgrowth, by minimizing some of those sugars, they tend to be less bloated and gassy. Now let's talk about rehydration and fluid management in these kids. So we're in the older child that has fluid losses, whether it be by stoma or any other source, we have to replace. If they are perpetually supported, that some of that fluid can be replaced IV. But as you're trying to move forward and get off IV support, if you can keep them hydrated by replenishing losses through enteral replacements, then that's important. For transport requires sodium and glucose, and so your solution that you're replacing with has to contain some glucose and some salt. So take into consideration if the patient has some IV parenteral support to replace fluids. If not, or you're trying to wean them off, you have to use a rehydration solution because the ionic composition is really important. And there are some homemade recipes for oral rehydration solutions. There's some over the counter type preps that you can get as well. Some people will resort to things like Gatorade and stuff like that, but that doesn't always work that well. It's actually too much sugar in it. I think some patients actually can come off a TPN but still need a central line for IV fluids, and that in the absence of IV fluids, really, they end up sleeping most of the days, they don't have a lot of energy. And it's hard to recommend back to a family that's lost the, you know, the kids come off TPM and you're seeing them, but being in a hydrated state is extremely important to making the bowel work well, and the compromise over time is the ability to stay hydrated, whether it's at night, through hydration, maybe even via G tube, or emphasizing. The need to stay hydrated. Sometimes they can't drink it, but the GI tract can use it. OK, so keeping the patient hydrated is very important, and for that we have many options. It can be by mouth, by nasogastric tube at night, or IV fluids. The other key point to remember is that the energy use goes up dramatically during puberty, and so you often will find a child who is actually doing well, and they hit the wall when they start puberty because their energy needs are overcoming their nutrient input. The goal is always healthy growth, and so it's not lost. Go backwards and to add things and supplement things and to hope sometimes that they'll take that one extra can of boost. It's all about normal growth parameters and get them through puberty. It is true some kids end up back on parental support, you know, to get through puberty. And then when you're not growing anymore as an adult, often that borderline or marginal gut function is enough to sustain them. That's really important. We have to be aware of puberty and moments of increased energy needs to guarantee a healthy growing, as the doctor said, we have to be proactive and keep our patients ahead of that to avoid losing opportunities for healthy growing. I can't emphasize enough to look at the growth chart, both the weight, but also the height, and don't accept a 3rd percentile. There are very few conditions with intestinal failure that have restricted growth, so, you know, you really need to put them in a healthy growth range, and the family needs to recognize that they have the potential. To do that, and so it's just setting expectations. A, you have to grow off TPM, but also then you have to monitor for a lot of the time you get into trouble after you get off TPM with micronutrient deficiencies, etc. That all needs to be followed, and then their long-term growth and outcome needs to be followed. So, hence the importance of teams, these multi-D teams. As always, we emphasize the need for a multidisciplinary team to help with the long-term follow-up and surveillance. Guaranteeing healthy growing is very important, and many of these patients don't have restricted growth, so we don't have to settle for a 3rd percentile. A, you have to grow off TPM, but also then you have to monitor. For a lot of the time you get into trouble after you get off TPN with micronutrient deficiencies, etc. that all needs to be followed, and then their long term growth and outcome needs to be followed. So, hence the importance of teams, these multi-D teams. There's times that you do not get to go back. So, a multidisciplinary approach highlighting this really from the get-go, um. It is really important. Again, to help our patients, we need a multidisciplinary team and set expectations to be met. Because I think we can't emphasize enough that these patients can and should achieve a normal growth. Now let's talk about how we follow these patients and make sure that they are normally growing. We track meat a lot as a major metric for growth, but it has to be balanced with their height. What we commonly see in this type of population is. Round babies where their weight for height is elevated, weight and height are basic metrics, anthropometrics that you can follow in a clinic setting or a hospital, but there's an increasing amount of data looking at, you know, quality of weight, how much is fat weight and how much is lean body mass. Great, so check weight and height, but also it's important to assess the type of weight they are gaining, because it's not the same fat as body mass. And now let's hear what we have to do if these patients are not achieving a good weight. Any child that's not meeting growth potential, there's numerous other diagnoses that can do it that range from endocrine issues to pancreatic insufficiency issues to micronutrient issues that that aren't there. There's a lot of things that you have to, to check off, but your concept is that they're capable. Of having normal growth and then as you address the issues and you improve something you need to then have a reasonable follow-up time and assess that you're making improvements in that which are on the orders of weeks and not months and they don't need to travel for us to get away and to check them. You can do a lot of this stuff remotely, but you can't wait till the next appointment. Amazing take home poets. Let's summarize. Eternal feeding in older patients is not the only main thing we get out of feeding because many social aspects are involved. Diet is really important and we have to avoid simple sugars, make smaller meals, and try to separate them from liquids. One main thing about these patients is that we have to keep them hydrated and to achieve that we need our special rehydration solutions, anti tubes with rehydration by the nights or even IV fluids because if our patients are not hydrated, they will not achieve a healthy growing as we always say, multidisciplinary team is really important and they will help us to follow our patients in the long term. To check our patients we not only have to see the weight but also the height and compare them to avoid having fat short heads. And in some cases we need to have another tools to acknowledge that the patient is having a healthy growing. So that was everything for today about how to re-feed older patients.
