Chapters

0:00Introduction and Case Presentation — Introduction of hosts and guests, including Dr. Mark Levitt, Dr. Jason Frischer, Sarah Ulrich (new colorectal fellow), and Dr. Chris Geyer (new Division Chief). Case presentation begins: 13-year-old with cloaca repair at 9 months, now presenting with daily fecal incontinence.
1:34History and Three-System Assessment — Discussion of the three-system approach to cloaca patients (urologic, gynecologic, colorectal). Patient has normal menstruation, no urinary accidents, but daily stool accidents. Original repair was perineal-only approach suggesting low cloaca. Emphasis on importance of gynecology collaboration.
4:51Physical Exam and Prior Workup — Physical exam reveals rectum within sphincter complex without stricture. Prior workup included cystoscopy/vaginoscopy showing narrow introitus and difficult urethral cannulation. Anorectal manometry showed pelvic floor dysfunction. Discussion of when manometry is appropriate versus electrical stimulation and imaging.
7:31Imaging Findings and Mega-rectosigmoid — MRI shows two hemiuteri with blood but not dilated, absent right kidney, healthy left kidney. Contrast enema from two years prior reveals massive rectal dilation with normal proximal colon. Discussion of etiology: inherent motility problem versus acquired from chronic constipation, likely both.
11:31Surgical Management Options — Debate on management approaches. If found at initial repair: would preserve rectum at colostomy closure. For current case: options include rectal tapering (like sleeve gastrectomy), Malone alone, or complete resection with sigmoid pull-through. Emphasis on preserving rectum for proprioception and continence. Discussion of sacral ratio 0.45 suggesting poor prognosis for spontaneous continence.
18:49Treatment Plan and Follow-up — Dr. Geyer's planned approach: Malone only initially, with family counseled that more definitive surgery may be needed. Discussion of when to divert and when stricture alone might explain dilation. Consensus that patient will likely require bowel management program.
20:58Closing and Joke — Episode concludes with patient-recorded colorectal joke and reminders about Stay Current app and social media.

Cases discussed

1:3413-year-old female with cloaca repair at 9 months, presenting with daily fecal incontinence and massive rectosigmoid dilation

Points of disagreement

17:52Optimal surgical approach for mega-rectosigmoid in this specific case
- Mark Levitt: Would perform redo PSARP, remove all perineal rectum, dissect out the mega-rectosigmoid, pull through proximal sigmoid, and do simultaneous Malone. Considers this a 0.1% case where complete resection is justified.
- Chris Geyer: Plans to try Malone only first, seeing if antegrade enemas alone will work, potentially avoiding resection. Had not initially considered tapering but finds it worth trying.
- Jason Frischer: Agrees with trying Malone only given the patient's response to enemas was impressive, but would counsel family that more definitive surgery may be needed.
9:40Etiology of mega-rectosigmoid: inherent versus acquired
- Jason Frischer: Questions whether it's a chicken-or-egg situation - was it inherent motility problem or evacuation problem, or was there congenital distension that perpetuated throughout childhood.
- Mark Levitt: States the answer is both - motility is inherent and problematic, but it can also be acquired from failure to aggressively treat constipation over many years.

Open questions

What is the initial insult in mega-rectosigmoid: inherent motility problem, evacuation problem, or congenital distension?
Will Malone alone be sufficient for this patient or will more definitive surgery be required?
Does rectal tapering maintain long-term results beyond one year post-operatively?
Can sigmoid colon provide adequate proprioception for continence after complete rectal resection in selected cases?

The Three-System Framework for Cloaca Patients

Every patient with cloaca history requires systematic evaluation of three systems: urologic, gynecologic, and colorectal 1:51. The history must address UTIs, voiding patterns, menstruation, and stool continence. This comprehensive approach prevents missing complications in any system. For urologic assessment, confirm successful bladder emptying with kidney ultrasound and check GFR using cystatin C 3:11. The principle that cloaca bladders need to stay empty to prevent kidney damage has transformed outcomes 3:11. Previously, 13-year-olds often presented with kidney damage requiring renal transplant 3:11. Aggressive bladder management prevents this trajectory.

Why the Rectum Matters More Than You Think

The rectum is vitally important for bowel control in anorectal malformation patients 11:53. These patients lack anal canal sensation and have no functional internal sphincter 11:53. Their continence mechanism depends entirely on proprioception — distention of the rectum provides the cue to squeeze the external sphincter and hold in stool 11:53. Remove the rectum and you eliminate the sensory signal needed for continence 11:53. This is why the PSARP technique, introduced in 1980, revolutionized care by preserving the rectum rather than discarding it 13:29. Older patients who had the prior abdominal perineal pull-through can be identified on contrast studies by haustral markings at the anus in the pelvis — sigmoid was pulled down where rectum should be 13:29.

When Perfect Anatomy Still Fails

Patients can have excellent anatomical repair and still have soiling 5:09. Before considering further intervention, verify the anal placement is correct — incorrect positioning is the most common reason for redo surgery 5:09. Use electrical stimulation and rectal ultrasound or MRI rather than anorectal manometry to determine proper positioning 6:29. Once you confirm the anus is well-located without stricture or prolapse, you face a different problem: the rectosigmoid itself can be inert even without mechanical obstruction 9:05.

The Mega-Rectosigmoid Problem

Mega-rectosigmoid develops from both inherent motility problems and acquired dilation from years of inadequately treated constipation 10:19. When you encounter massive rectal dilation in a patient with good anal anatomy, you have several options. Rectal tapering can be performed laparoscopically or open, either at colostomy closure or after failed bowel management 14:22. The technique mirrors sleeve gastrectomy: taper the anti-mesenteric side with a stent or dilator in the rectum to ensure adequate lumen, using stapling and sometimes over-sewing 15:45. Post-operative studies show improved bowel management and no re-dilation at one year 15:45.

Knowing When Surgery Won't Win

A sacral ratio of 0.45 indicates poor sacral development and inadequate perineal musculature 16:49. These patients will likely never achieve spontaneous bowel control regardless of surgical technique, given the quality of their pelvis and degree of sacral regression 16:49. For such patients, bowel management programs rather than additional reconstructive surgery may be the appropriate endpoint. However, colons can empty surprisingly well with antegrade enemas alone, potentially avoiding resection 17:52.

The Decision Tree for Massive Dilation

When facing mega-rectosigmoid, first assess the anal opening. Very often these patients have analplasty that is not good — either strictured, mislocated, or prolapsed 19:24. If the anus is just strictured, making it bigger might allow the colon to decompress and improve 20:14. If the anus is well-positioned and the dilation persists, consider Malone antegrade enema first, knowing it may not succeed. If the analplasty requires redo anyway, you face the decision between tapering the rectum to preserve proprioception or resecting it entirely and accepting that the patient will need a bowel management program. The choice depends on sacral anatomy, family goals, and whether the dilation appears inherent or acquired.

Takeaways from this story

ARM patients depend on rectal proprioception for continence since they lack anal canal sensation and internal sphincter function
Mega-rectosigmoid can be tapered rather than resected to preserve proprioception, with good one-year outcomes and no re-dilation
Sacral ratio of 0.45 predicts patients unlikely to achieve spontaneous continence regardless of surgical technique
Strictured anus may be the primary problem — enlarging it can allow mega-rectosigmoid to decompress without resection
Cloaca bladders must stay empty to prevent kidney damage; aggressive bladder management has eliminated most renal transplants

Topic overview

A multidisciplinary discussion of a 13-year-old female with a history of cloaca repair at nine months presenting with daily fecal incontinence and massive rectosigmoid dilation (mega-rectosigmoid). The patient has a well-positioned, non-strictured anus, functioning urinary and gynecologic systems, and a sacral ratio of 0.45. The panel debates surgical management options including Malone antegrade continence enema (MACE) alone, rectal tapering, or complete resection with sigmoid pull-through, with consensus that the patient will likely require bowel management rather than achieving spontaneous continence given her pelvic anatomy.

Key takeaways

Mega-rectosigmoid in ARM stems from both inherent motility defects and years of undertreated constipation. (10:19)
Rectal preservation is critical in ARM—proprioception from rectal distention cues external sphincter contraction. (11:53)
Sacral ratio 0.45 predicts poor spontaneous continence; patient will likely need lifelong bowel management. (16:49)
Rectal tapering (anti-mesenteric stapling) can make antegrade enemas more effective without re-dilation at 1 year. (15:45)
Always assess urologic, gynecologic, and colorectal systems in cloaca patients; renal damage was common historically. (1:51)

Welcome to another episode of the Colorectal Quiz. I am Filipe Jaldes, Colorectal Research Fellow at Children's National Hospital, Washington, D.C., and today we'll be discussing mega-rectosigmoid. Make sure you download the StakeCurrent app to follow along with images and other related cases. Today we are joined by Dr. Mark Levitt from Children's National Hospital and Dr. Jason Frischer from Cincinnati Children's Hospital. Welcome everyone. Glad to have you back to the Colorectal Quiz. We have some special guests today, but most importantly, I'm excited to see my good friend, Dr. Levitt. As handsome as ever, wow, I feel bad for our listeners because they don't get to see you. Yes, so they always said that I had a face for radio. Dr. Levitt will introduce our guest for this episode of the Colorectal Quiz. Welcome, Sarah Ulrich, who is coming from Yale to Cincinnati Children's to be the new Colorectal Fellow. Great to have you joining. And we have a very special guest coming all the way from Los Angeles, our good friend Chris Geyer. Welcome and congratulations, Chris, on your new physician as the Division Chief of Pediatric Surgery. And I hope that that does not take you away from your love of colorectal. And here we go with Dr. Geyer, starting us off with the case. So this patient just saw us recently, and as you mentioned, very complex. She is 13 years old. She had a cloaco repair around nine months of age at an outside hospital. And at the time of our initial evaluation, we did not have any operative reports available or any other records besides family history. As Dr. Levitt likes to remind us, every patient with a cloacoal history, we have to remember to think about three systems. We talked about this on other podcasts. You got to worry about the three systems, urologic, gynecologic, and colorectal. Okay, so this means the history needs to be focused on these systems. So be sure to investigate if they have urinary tract infections. Are they voiding well? Have they started menstruating? And are they toilet trained for stooling? And are they having any accidents? She has begun menstruating, and she's not had any issues with menstruation. And she currently endorses no urinary accidents, but does have stooling accidents daily. So it's likely that she has a good gynecologic system that at least empties her Mullerian system without pain. And she probably has a good urinary system. She's got a good bladder neck. She's voiding. She has control. She's not having urinary tract infections. We would want to check all of that. We would want to be absolutely certain that she's successfully emptying her bladder, kidney ultrasound. Cystatin C is helpful to check her GFR, her renal function. The particular attention to the renal function is a relatively new advancement in care for these children to ensure they do not require a renal transplant. I want to say that, you know, thank you to Kurt Sheldon, who was both a urologist and a pediatric surgeon by training, who was my mentor when I joined in Cincinnati in 2005 and began a wonderful friendship and partnership with Jason. He was the one that said spina bifida bladders need to stay empty. Cholaica bladders need to stay empty. And it was that move which made a huge difference in keeping those patients from having kidney damage. Because it used to be that a 13-year-old like this often would show up with kidney damage. And many of them, unfortunately, ended up with renal transplant. For redo cases, need to assess operative technique. So the history on the surgery per the family was that this operation was done entirely via a perineal approach. So it sounds to me that likely this original cholaica was relatively low because it was a perineal only repair. So in this case, it sounds like the urethra is there, the vagina is there, although the introidos made an inspection for intercourse later in life. And these patients do require cesarean section for childbirth. I can't emphasize enough how important it is to have a gynecologist that you are friendly with, that helps you, keeps you out of trouble, and sees all of the female patients with an anorectal malformation. So if you don't have one, find one, take them out to a nice dinner, order a really nice bottle of wine, and keep them close. Because every patient with an anorectal malformation needs a colleague in gynecology to make sure they're doing well. Back to our case. So in the clinic on our exam, her rectum appeared visually to be within her sphincter complex, and she had no strictures on rectal exam. So let me just add to that. Thank you for mentioning that. Is the anus okay? Yes or no? If it's perfect, they still may have soiling. That's the most incredibly frustrating thing about anorectal malformation patients. You've done an excellent anatomical repair, and they still have soiling. This patient sounds like they have a rectum that's well-located, without stricture, without prolapse. Of course, they're soiling. You've got to figure out why they're soiling. But there's no anal surgery required for this patient. But it is the first thing you need to check. And the reason why it's the first thing to check is because if the anus was placed in the wrong position, she may need surgery to redo her anal placement, which is the most common cause for redoing anorectal malformation patients. Dr. Geyer will tell us more about her workup regarding her urinary, gynecologic, and colorectal systems. So two years prior, she had come to our urologist outside of our center and had had a cystoscopy, vaginoscopy. And they commented on a narrow introitus at that time, a difficult to cannulate urethra, but they were able to ultimately cannulate it with a nine and a half French scope. And during that time, she also had anorectal mal, anorectal manometry that showed some pelvic floor dysfunction and what they called, quote, normal sensation. Dr. Frischer doesn't usually start with anorectal manometry. So we don't typically do anorectal manometry in our anorectal malformation patients as part of the standard initial workup. I never say never and I never say always, but it's not part of our standard evaluation. I think it's something that we save for circumstances that we have trouble figuring out. Because there are many ways to tell if the anus is in the proper position, such as electrical stimulation and the rectal ultrasound or MRI. That being said, often you could just tell on your physical exam and using electrical stimulation during your exam under anesthesia. You should be able to tell that by looking and by electrical stimulation. So all these patients get an EUA, which is exactly what Chris, you did. It sounds to me like the anus is now cleared anatomically. This patient is good at the perineal level, at least. So in this case, Dr. Geyer started with an MRI and be sure to check out the Stay Current app to see the pictures and follow along. Please get the, if you don't have it, the Stay Current app. And if you do have it and you're jogging right now, listening to this podcast, being inspired to run fast, you should look down on your phone because you can see a beautiful image of an MRI. And on this MRI, you can actually see- Wait, wait. But if you're driving, don't look. Wait, don't look. This is, this is from our lawyers. They just called in. They said, do not look if you're driving. Wait till you get to your, your destination. Thank you. Yes. Thank you. Thank you very much. And it's amazing that the lawyers seem to be monitoring this podcast. But the MRI shows two hemiuteri with some blood in them, but they're not at all dilated. It looks like the right tube has some fullness to it. And of course, you did mention this already, but there's obviously no kidney on the patient's right side. Good news is there's a healthy kidney on the left side. So with that, we can clear the urologic and gynecologic systems as being in working order and focus on the soiling and optimizing the colorectal system. So the next set of images, you'll see a contrast enema done two years prior that shows a rather not so subtle rectal dilation with more proximal colon being a relatively normal cow. Wow. I have one word. Wow. Jason, this would, this would win the Ohio State Fair. This is this deserves its own name. Like it's its separate organ. How you know, let's talk about this for a second. You have an anus that is not strictured. Okay. Why does this happen? It's so frustrating in ARM patients that the, the rectosigmoid can be so inert. Um, this is impressive. But Mark, this is one of those things I always wonder, cause we all have a few patients that have this anatomy like chicken or the egg. Like what came first? Cause this likely started as a quite dilated rectum from minute one. Especially you said there's a perineal repair. So you didn't, or whomever did the repair, didn't get a full view of the rectum at that time. So things do get worse over time, but what was the initial insult? Was it a motility problem or evacuation problem? Or was there some congenital distension that just perpetuated throughout childhood? So the answer is both. Um, um, it can't, it, and it can be inherent. I think the motility is inherent, the problematic that we all know that most of these patients need constipation treatment. And I also think in some respects it can be acquired from the failure to aggressively treat constipation over many, many years. It eventually dilates and dilates and dilates. So this, if you're looking at the image on your app, you see essentially a rectosigmoid, which takes up the entire abdomen pretty much. And remember, this is a patient with no stricture. I think that's key is that there's also no stricture because that could play a role, but we know that's not the case here. Of note, also very interestingly, is the transverse and left colon and the very proximal sigmoid colon looks beautiful, healthy, haustral markings, meaning there is peristalsis there. And then boom, this enormous rectosigmoid just imposes all the stasis on this poor child. Obviously this has to be managed and this brings up a very interesting treatment scenario. So let's backtrack and think about a different case. What if this was found at time of initial repair at nine months old? I want to start there and then we can talk about what you do when you're finding out. But if you went in to do your initial repair at nine months of age and had similar type of anatomy, how would you address it at that point in time? Well, I would do the usual analplasty, but then I think at the time of the colostomy closure, I might take out some of this enormity. I would leave the rectum. Generally, you want to leave the rectum because the rectum is vitally important in anorectal malformation patients. In general, you want to keep the rectum because the rectum is vital for bowel control. In an anorectal malformation patient, I cannot emphasize that importance. Why? They don't really have anal canal sensation. They don't really have an anal canal. So that's out. They don't really have any form of an internal sphincter unless the very distal aspect of the rectum was saved. Some patients have an external sphincter depending on how well formed the pelvis is, which you can determine by sacral measurements. Now, how do they know to use their external sphincter? What's the cue to squeezing the external sphincter and holding in the stool? Distention of the rectum called proprioception. So with that distention, you say, I feel something is there. I must squeeze. And then you squeeze the very nice external sphincter. If you have them, if you don't have them, then that's not a patient who's ever going to have bowel control. Okay. So that distention is key. If you remove the rectum, you lose that capacity. Dr. Levitt clue us into the prepayment world before digitalization of the PSARP approach from 1980. From a surgical point of view, Sarah, 1980 is really new for an operation. All the esophageal atresia, all that stuff was in the 50s when they started being able to get patients anesthesia and things like that. But the prior to the PSARP, what was done? The same concept that was used for Hirschsprung's disease, an abdominal perineal pull through, throw the rectum away, pull the sigmoid down. That was wrong. Obviously, the PSARP revolutionized that concept. But you may see an older patient who had an abdominal perineal pull through, and you'll recognize that because on the contrast study, you see haustral markings at the anus, in the pelvis, meaning they pulled through sigmoid because obviously the rectum has no haustral. Okay. But Dr. Levitt, what about in our case? This case is different. I want to say that. This case is different, at least in my mind. I'm not going to say exactly what I would do. But this rectum is, wow, just out of control. Like, how would one save this thing? So I'm curious to know, Chris, what you did. This is like a living creature within this child's abdomen. But I have done, in a few cases of these mega rectosigmoids in anal rectal malformations for the reasons you just so eloquently discussed of removing the rectum almost guarantees incontinence, is that I've tapered these both laparoscopically and open and at the time of colostomy closure and at the time of, after failed bowel management. And I've had relatively good success. Now the end in that is an anecdotal, you know, you could count it on definitely less than two hands, how many I've done, but it's been successful. And just a reminder, there are some images of this tapering technique on this TakeArend app. So be sure to check this out so you can picture what we are talking about here. Tell me what you actually do. I mean, literally go in there laparoscopically or open, find this large rectosigmoid, and on the anti-mesenteric side, taper. Make sure you have someone, you know, full body prep or split leg table, depending on the size and age of the child, having a stent or a dilator in the rectum. So I know that I have a good size lumen. Like a sleeve gastrectomy. Like a sleeve gastrectomy or like a proximal jejunal atresia. And I staple and I over-sow. Sometimes I over-sow, sometimes I don't. But, and I've studied these kids afterwards. First of all, their bowel management becomes more manageable. And then two, I've studied their, their, um, anatomy afterwards. And I haven't seen dilation. I've only studied anatomy like a year after. I haven't watched over many, many years, but I'm still following those patients. In many of these kids, even with the best operative plans, they still have trouble in incontinence. And frequently it's just a matter of their anatomy and their musculature. I see that the sacrum ratio is 0.45. The sacrum is not great. Um, so the perineum, the musculature is probably not great. So I think this patient is going to be a bowel management candidate. And I doubt they will ever achieve successful bowel control anyway, given the quality of their pelvis, the amount of quadruple regression that they have. So what I would do in this case, in this unique case is I would remove that entire thing and pull through the proximal sigmoid and make a beautiful, well-sized analplasty and do a Malone at the same time and say, that's the way they're going to be. And Dr. Levitt has had some patients with good success with continence where the sigmoid is able to feel some distension, but it certainly isn't the expectation. I would do a redo for this patient. I would do a redo PSARP, remove all the perineal rectum, dissect it out, go into the abdomen, dissect out this monstrosity and pull through the proximal sigmoid, close the posterior sagittal incision and having, would have done a Malone. That's a 0.1% case. The other 99 plus percent cases, I would do a sigmoid resection if necessary, but usually you don't have to do that. Usually a Malone only is all you need. And honestly, for this case, I might even consider trying that knowing that it might not work, but you'd be surprised how well colons empty with antegrade only and completely avoid a resection. In Dr. Guy, your patient, she had the initial enemas, eventually became a burden on their quality of life and the family was lost to follow up. And when she represented, she had this difficulty of incontinence and distension of the rectum. And so the question is, what is he going to do next? So we haven't done anything yet. I had planned on doing a Malone only and trying and seeing if that would work. I had not thought about the tapering idea. It does make sense. I can't imagine it'll be super easy on this, but it might be worth a try over redoing the entire thing. But yeah, I think, I think I agree with you, particularly the response to enemas was impressive. I would do Malone only, see how it goes, but I would tell the family that might not succeed and you may need to be, do something more definitive and remove some colon. And then you have the tapering option or the take the whole thing out and bring the sigmoid down option. I will say that very often you have a patient like this and the analplasty is not good. It's either strictured, mislocated or prolapsed. So you have to redo the analplasty anyway. And then I think you're faced with a very difficult decision because you have to do a PSARP of some sort, a redo PSARP of some sort. In that case, I would do the whole shebang that I just said. However, you divert the patient at that time as well? I would not. I would not divert. However, if if it was just a stricture, I might make the anus bigger and give that a chance to decompress because that colon might get a heck of a lot better. But if it was not strictured and it was this enormous, then I would say that thing Frischer said about the inherent problem. It was probably there since birth. It's probably true. I'd probably go ahead and resect it. This is a great case, Mark. Really, I love it. This is great, Chris. Thank you so much for sharing. Let us know what happens. For sure, I will. And now for our episodic colorectal quiz joke. We had a patient today who always tells me colorectal jokes. So I asked him and his parents, would he like to record his joke? And I will play it for our international audience directly with his voice. Which we've never done before. And I'm going to play it now. This is a first. Drum roll, please. All right. Here we go. Just a colorectal surgeon have in common with the astronaut. They both see Uranus. Nice. Nice. And for those of you who didn't catch that, our wonderful patient said, what does a colorectal surgeon and an astronaut have in common? And he said the answer was, they both see your anus. Phenomenal. Phenomenal. Thank you all for joining us for this episode of the colorectal quiz. And remember to download the Seekerin app from the Apple App Store or the Google Play Store to check out the images and algorithms we discussed in this episode. Additionally, remember to follow us on social media and check out our YouTube channel for more pediatric surgery content. and I'm so sure o'erh, I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can go. I can. I can. I can. I can. I can. I can. I can.
