- "You avoid bladder neck injury by knowing exactly where the rectum is from a properly done distal colostogram. When you open posterior sagittal, you know the rectum is right under the coccyx (prostatic) or distal to the coccyx (bulbar), or it isn't posterior sagittal at all (bladder neck—do laparoscopy)." — Marc Levitt (clinical) [Ep 230 · 27:30](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=1650)
- "Dr. Levitt will do posterior sagittal for bulbar fistulas and low prostatic fistulas with a bulge.

- "If you try laparoscopy for a rectum bulging below the peritoneal reflection at low prostatic or bulbar level, you may leave behind a remnant of the original fistula (ROOF)—the distal rectum left behind that causes trouble later." — Marc Levitt (clinical) [Ep 230 · 30:50](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=1850)
- "Laparoscopy replaces laparotomy, not PSARP. Dr. Levitt does a mini-PSARP when doing laparoscopy to safely enter the pelvis and tack the rectum to the posterior edge of the muscle complex to avoid prolapse." — Marc Levitt (clinical) [Ep 230 · 31:38](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=1898)

- "Dr. Levitt trims prolapse of more than about 3mm. For circumferential prolapse, he does half the circumference in two different ambulatory settings so families don't need hospitalization and the patient doesn't need dilation (half the circumference is untouched so they won't stricture)." — Marc Levitt (clinical) [Ep 230 · 34:30](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2070)

- "The key to preventing perineal body dehiscence is mobilizing the rectum well—you must get the anterior rectal wall completely separated from the posterior vaginal wall to the areolar plane. If you don't, the anoplasty will be under tension and can pull back, leak into the perineal body space, and dehisce." — Marc Levitt (clinical) [Ep 230 · 35:55](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2155)

- "Traditionally Dr. Levitt kept patients NPO for 7 days on 10% dextrose after female ARM repair. Recently he has been trialing clear liquids only for a week because the major problem is hard stool—clear liquids won't make hard stool." — Marc Levitt (clinical) [Ep 230 · 37:15](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2235)
- "If perineal body dehiscence is detected on days 5-8, Dr. Levitt will take the patient back to the OR and re-suture the perineal body, which can salvage the situation. This happens in maybe 1-2 cases out of about 200." — Marc Levitt (clinical) [Ep 230 · 37:47](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2267)

- "For high rectums, particularly bladder neck fistulas, the dissection of the distal rectum is quite challenging to make it reach with good blood supply. You must preserve the IMA because the colostomy may have disrupted collaterals down the left colic, making the rectum completely dependent on the IMA." — Marc Levitt (clinical) [Ep 230 · 39:10](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2350)
- "The rectum has an excellent intramural blood supply from the IMA. If you take the IMA or take branches too close to the aorta, the rectum will die because there's no collateralization down the left colic." — Marc Levitt (clinical) [Ep 230 · 39:40](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2380)

- "A bulbar fistula with a good sacrum (sacral ratio of 1) and normal spine should absolutely have bowel control. A bladder neck fistula with poor sacrum (sacral ratio 0.4) and tethered cord or myelomeningocele has no real chance of good bowel control." — Marc Levitt (clinical) [Ep 230 · 43:45](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2625)
- "For a soiling 4-year-old ARM patient, Dr. Levitt's first step is to get them clean mechanically with bowel management using enemas.

- "One of the biggest problems with ARM is that if you don't get it right, you don't know for a few years. Most surgical problems become obvious immediately, but with ARM, patients may not present with soiling until age 4, making it hard for surgeons to learn what to fix about their technique." — Marc Levitt (opinion) [Ep 230 · 46:05](https://qa.library.globalcastmd.com/watch/anorectal-malformations-complications-13872?t=2765)

- "Proper technique requires marking 1 cm proximal to the dentate line with a purple mark and placing 5-0 silk stitches circumferentially at that level.

- "By definition, you're leaving behind 1 cm of columnar epithelium that is Hirschsprung disease, plus the internal sphincter which has a problem with relaxation. However, good ganglionic bowel is able to overcome that, and the baby eventually learns to relax the sphincter." — Marc Levitt (clinical) [Ep 76 · 36:39](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-part-i-with-marc-levitt-311?t=2199)
- "The rectum doesn't really have a mesentery; the rectum's blood supply is intramural.

- "For laparoscopic biopsies through the umbilicus, a seromuscular biopsy (without violating mucosa) may show ganglion cells in the seromuscular layer but miss hypertrophic nerves in the submucosa.

- "It's preferable to take the IMA, preserve the arcade, and have the left colon and sigmoid nice and straight down into the perineum. This makes for an easy-to-irrigate baby.

- "For anything proximal to the splenic flexure, do colonic biopsies and an ileostomy and wait, because frozen section has been notoriously fraught with errors in those cases. There is no urgency.

- "Postoperatively, wait until the belly is absolutely soft and flat with bowel function before feeding. Get an X-ray because abdominal distention is sometimes subclinical.

- "With laparoscopy or robotics, you can go much lower than with laparotomy, but you want to get to the very end of vaginal insertion onto the common channel, which is hard to do.

- "In anorectal malformations, anal dilations start with a very small Hegar and increase weekly; in Hirschsprung, dilations can start near the goal size (e.g., size 12 if goal is 13) because the anastomosis is deeper and usually less tight." — Andrea Bischoff (clinical) [Ep 42 · 88:40](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-cases-and-complications-1028?t=5320)

- "Before making a diagnosis of Hirschsprung in a patient with anorectal malformation, surgeons should think carefully—most likely it is not Hirschsprung, as many patients have constipation but very few have true Hirschsprung." (opinion) [Ep 42 · 94:10](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-cases-and-complications-1028?t=5650)
- "For hypermotile (diarrhea-prone) Hirschsprung patients with fecal incontinence, the correct bowel management is small-volume saline enemas only (250 mL), not laxatives, fiber, or enemas with additives." — Andrea Bischoff (clinical) [Ep 42 · 97:00](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-cases-and-complications-1028?t=5820)

- "Published experience with sacral nerve stimulation (InterStim) in anorectal malformations is limited to only 10 patients in the literature, without specification of malformation type or sacral quality, making results impossible to evaluate." — Andrea Bischoff (epidemiological) [Ep 42 · 100:23](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-cases-and-complications-1028?t=6023)

- "Midline laparotomy incisions are preferred over transverse incisions for Hirschsprung surgery because they provide excellent exposure, can be extended if needed, and allow mobilization of splenic and hepatic flexures when necessary." — Andrea Bischoff (opinion) [Ep 42 · 73:31](https://qa.library.globalcastmd.com/watch/hirschsprung-disease-cases-and-complications-1028?t=4411)
- "The priority in surgery is to finish the operation happy—surgeon happiness at the end of the procedure is very important, and the family feels happy when the surgeon is confident, allowing the surgeon to sleep well."

## Common questions
### Give me more information about hirschsprung's disease?
Hirschsprung disease is a congenital developmental anomaly of intestinal ganglion cell migration that results in a functional bowel obstruction. It represents a loss of innervation to a section of bowel, typically affecting the lowermost aspect of the intestine, particularly the rectum or sigmoid. The condition is classified as a rare birth defect, though the exact cause remains unknown. Failure to pass meconium within the first 48 hours of life is a typical clinical presentation. Hirschsprung disease can be associated with genetic syndromes such as Down syndrome. The disease exists in different forms—proximal, distal, short segment, and total colonic variants—each requiring different operative approaches. Irrigations represent the best treatment, and while surgical emergency is rare, it becomes likely without irrigation. Diagnosis requires histopathological confirmation of absent ganglion cells across multiple levels with hypertrophic nerves.
