Intestinal Rehabilitation, Episode 3: Enteral Autonomy, Part 2
A paper from Chris Duggan's group at Boston demonstrated that implementation of a feeding protocol is associated with achieving full autonomy in a shorter time period

Bowel heals with adhesions that bring blood supply to the bowel and help it heal
clinicalHelmuth2:45 β
Very high outputs can occur initially in damaged bowel that requires luminal nutrition to start getting the bowel to learn how to reabsorb fluid
clinicalHelmuth3:56 β
High outputs without feeding are an indication to feed, as long as the child can be hydrated
clinicalHelmuth4:10 β
After massive resection and loss of distal bowel, patients can be hypergastrinemic and have elevated acid secretion for 6 to 12 months due to loss of hormonal feedback messaging
clinicalWales4:35 β
Acid blockade with H2 blockers or PPIs can decrease gastric volume in the short term
clinicalWales4:57 β
Acid blockade carries a counter risk of bacterial overgrowth by losing the acid barrier
clinicalWales5:11 β
Increased secretions occur because of a thick, leaky mucosa, and the way to improve that is to heal the mucosa, which requires delivery of luminal nutrients
clinicalWales5:59 β
If serum bicarbonate is kept above 20, feeding is generally safe even with high cc per kilo output
clinicalHelmuth6:17 β
Cycled antibiotics for bacterial overgrowth are often done very empiric and ad hoc
clinicalWales6:49 β
Closing a stoma immediately recruits more bowel and restores continuity
clinicalWales7:58 β
As bowel becomes increasingly dilated, its motility becomes impaired
clinicalWales8:36 β
In dilated bowel with impaired motility, stool doesn't move, leading to mucosal inflammation, damage to the mucosal barrier allowing bacterial translocation, potential sepsis, and malabsorption
clinicalRod8:41 β
Restoring bowel caliber to something more normal can improve motility, provide better stool clearance, decrease bacterial overgrowth, allow mucosa to heal, and improve absorptive function

The Bianchi procedure (longitudinal intestinal lengthening) has been around since 1980
clinicalWales9:33 β
One of the most important factors for efficacy of both Bianchi and STEP procedures is that you're tapering the bowel
clinicalWales9:45 β
STEP differs from anti-mesenteric tapering or resection in that it preserves all available mucosa without removing any
clinicalWales9:51 β
Bowel lengthening procedures primarily redistribute surface area rather than truly increasing it
clinicalRod10:55 β
It takes about 6 months to see any changes in absorption after bowel lengthening procedures
clinicalEllen11:05 β
Cincinnati published experience showing absorption changes over time using fecal fat, alpha-1 antitrypsin clearance, xylose as measures of macronutrient absorption, and citrulline rise
clinicalWales11:08 β
An upper GI can only rule in a problem; it does not rule out a problem
clinicalEllen11:34 β
A normal upper GI does not rule out an anatomical problem
clinicalHelmuth11:48 β
The new ASPEN guidelines define enteral autonomy as independence from parenteral support for 12 weeks

Intestinal Rehabilitation, Episode 2: Overwhelming intestinal damage, Part 2
In Toronto, ultra-short gut is classified as less than 20% of expected bowel length for age
clinicalPaul Wales1:37 β
In a term baby, ultra-short gut corresponds to 20 to 30 centimeters of bowel
clinicalPaul Wales1:42 β
Overall survival in ultra-short gut patients in the current era is over 90%
clinicalPaul Wales1:52 β
Survival in ultra-short gut is actually 90 to 95%
clinicalEllen2:01 β
Ultra-short gut patients don't die of liver failure anymore and rarely get transplanted
clinicalEllen2:03 β
Ultra-short gut patients who reached autonomy required multiple nutritional supplements
clinicalPaul Wales2:10 β
Ultra-short gut patients with remnant ileum as part of residual bowel tended to do better
