## Statements
Every statement is attributed, typed, and timestamped; the link is the citation.
- Anorectal malformations are commonly not properly diagnosed or completely missed in the newborn period. — Marc Levitt (clinical) [Ep 5 · 2:57](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=177)
- Male babies with perineal fistula may pass meconium and no one notices anything wrong with their anorectal anatomy, typically presenting in the first year of life with severe constipation. — Marc Levitt (clinical) [Ep 5 · 3:06](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=186)
- A newborn anus should accept a size 12 Hagar dilator and a 1-year-old should accept a size 15. — Marc Levitt (clinical) [Ep 5 · 6:13](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=373)
- Relocating a perineal fistula into the sphincters improves anatomy but does not completely fix constipation; patients will inherently have some constipation requiring aggressive treatment. — Marc Levitt (clinical) [Ep 5 · 4:54](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=294)
- If a perineal fistula is not centered in the sphincter, patients with loose stool will soil, and athletic activity will cause soiling because sphincter squeeze cannot completely close the hole. — Marc Levitt (clinical) [Ep 5 · 5:38](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=338)
- In females, diagnostic criteria for perineal fistula are: hole too close to vagina (inadequate perineal body), inadequate hole size by Hagar dilators, and hole not centered in sphincter. — Marc Levitt (clinical) [Ep 5 · 8:02](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=482)
- If a female's anal opening is adequate size and centered in the sphincter, even if appearing slightly anterior with short perineal body, no surgery is needed; the perineal body will lengthen with growth. — Marc Levitt (clinical) [Ep 5 · 8:47](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=527)
- The standard practice of checking temperature on forehead or ear rather than rectally makes it easier to miss anorectal malformations in newborns. — Marc Levitt (opinion) [Ep 5 · 4:25](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=265)
- An anesthesia nerve stimulator costing $150 with appropriate needle probes works as well as commercial $15,000 stimulators for identifying sphincter muscles. — Marc Levitt (clinical) [Ep 5 · 11:06](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=666)
- The most common colostomy error is opening too distal in the sigmoid, restricting the ultimate pull-through by the location of the colostomy or mucous fistula. — Marc Levitt (clinical) [Ep 5 · 17:18](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1038)
- Incompletely diverting loop colostomies allow stool to spill across and contaminate the distal segment, leading to urinary tract infections. — Marc Levitt (clinical) [Ep 5 · 17:45](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1065)
- With transverse colostomy and large rectourethral fistula, the left colon absorbs urine which doesn't exit the mucous fistula, potentially causing acidosis from urine absorption. — Marc Levitt (clinical) [Ep 5 · 18:38](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1118)
- Prolapse risk depends on colostomy location: mid-transverse allows bilateral prolapse, hepatic flexure allows only distal prolapse, proximal sigmoid allows only distal prolapse because left colon is fixed to retroperitoneum. — Marc Levitt (clinical) [Ep 5 · 19:58](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1198)
- Marking the sphincter ellipse on skin surface before making any incision prevents confusion from muscle stimulation after dissection is open, avoiding misplaced anoplasty. — Marc Levitt (clinical) [Ep 5 · 21:30](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1290)
- A distal colostogram showing flattening of the rectum corresponding to the pubococcygeal line indicates insufficient contrast or pressure; more pressure is needed to overcome the sphincters and reveal the true rectal position and fistula. — Marc Levitt (clinical) [Ep 5 · 24:26](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1466)
- Fistula level is determined by viewing the urethra as a reverse C or elbow: fistula at or below the elbow is bulbar, above the elbow is prostatic, at bladder neck is bladder neck fistula. — Marc Levitt (clinical) [Ep 5 · 25:23](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1523)
- Bulbous rectum on colostogram may be reachable posterior sagittally and difficult laparoscopically; tapered rectum is better approached laparoscopically. — Marc Levitt (clinical) [Ep 5 · 25:55](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1555)
- Opening posterior sagittally without knowing exact rectal location risks finding and potentially mobilizing bladder neck instead of rectum. — Marc Levitt (clinical) [Ep 5 · 27:00](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1620)
- Bulbar and low prostatic fistulas with bulbous rectum are best approached posterior sagittally; high prostatic with tapered rectum and bladder neck fistulas are best approached laparoscopically. — Marc Levitt (clinical) [Ep 5 · 30:09](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1809)
- Attempting laparoscopy for bulging rectum below peritoneal reflection at low prostatic or bulbar level risks leaving behind a remnant of the original fistula (roof) if the surgeon is timid. — Marc Levitt (clinical) [Ep 5 · 30:43](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1843)
- Laparoscopy replaces laparotomy, not PSARP; a mini-PSARP during laparoscopy allows safe entry through peritoneal reflection and tacking rectum to posterior muscle complex to prevent prolapse. — Marc Levitt (opinion) [Ep 5 · 31:48](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=1908)
- Rectal prolapse occurs in about 3% of cases, particularly in patients without great muscles. — Marc Levitt (epidemiological) [Ep 5 · 33:35](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2015)
- Rectal prolapse more than 3 millimeters should be treated because it causes bleeding, mucus, and can inhibit bowel control in patients with good muscle potential. — Marc Levitt (clinical) [Ep 5 · 34:14](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2054)
- Circumferential prolapse can be trimmed in two separate ambulatory sessions (half circumference each), avoiding hospitalization and eliminating need for dilation since half the circumference remains untouched. — Marc Levitt (clinical) [Ep 5 · 34:48](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2088)
- Perineal body dehiscence is the most common cause of reoperation in female ARM repairs. — Marc Levitt (clinical) [Ep 5 · 36:03](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2163)
- Complete anterior rectal wall mobilization to the areolar plane between rectum and vagina is essential to avoid tension on the anoplasty that can lead to perineal body dehiscence. — Marc Levitt (clinical) [Ep 5 · 35:41](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2141)
- Clear liquids only for one week postoperatively prevents hard stool formation while allowing more stool volume, showing good perineal body healing results without traditional 7-day NPO period. — Marc Levitt (clinical) [Ep 5 · 36:45](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2205)
- If perineal body dehiscence is recognized on days 5-8, taking the patient back to OR to re-suture can salvage the repair; by 3-4 weeks the entire perineal body is dehisced and unsalvageable. — Marc Levitt (clinical) [Ep 5 · 37:48](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2268)
- During laparoscopic approach for high rectums, the IMA must be preserved because prior colostomy may have disrupted collaterals down the left colic, making the rectum completely dependent on IMA blood supply. — Marc Levitt (clinical) [Ep 5 · 39:33](https://library.globalcastmd.com/watch/complications-of-anorectal-malformations-with-dr-marc-levitt-304?t=2373)
- Continence potential in ARM patients is predicted by three factors: original malformation type, sacral ratio, and spine quality (ARM continence index).

- Vaginostomy can be performed with or without a tube. Tubes can become encrusted and colonized, so tubeless (suturing vagina to abdominal wall) may be preferable if the vagina reaches the abdominal wall easily. — Richard Wood (clinical) [Ep 10 · 21:00](https://library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=1260)

- Post-discharge follow-up for cloaca: monitor kidney decompression with serial ultrasounds, follow kidney function tests, ensure stoma management and growth. Definitive imaging and reconstructive planning are deferred until the patient is growing and thriving. — Richard Wood (guideline) [Ep 10 · 24:36](https://library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=1476)

- In type 1 cloaca, the hypospadic urethral orifice is not touched; the plan is vaginoplasty, anorectoplasty, and PSARP. — Richard Wood (clinical) [Ep 11 · 10:57](https://library.globalcastmd.com/watch/colorectal-quiz-episode-18-cloaca-part-2-4336?t=657)
- Even in type 1 cloaca, the true rectum can still be high, so imaging is important to determine rectal position. — Richard Wood (clinical) [Ep 11 · 11:17](https://library.globalcastmd.com/watch/colorectal-quiz-episode-18-cloaca-part-2-4336?t=677)
