- Placement of a catheter into the common channel is challenging because it may go into any of three organ systems (bladder, vagina, or rectum), making standard VCUG unreliable. (clinical) [Ep 4 · 16:02](https://origin-library.globalcastmd.com/watch/cloaca-workup-evaluation-683?t=962)
- High-grade reflux is not commonly identified in cloacal malformation patients; most reflux is mild and warrants observation rather than mandatory preoperative intervention. (clinical) [Ep 4 · 16:54](https://origin-library.globalcastmd.com/watch/cloaca-workup-evaluation-683?t=1014)
- In neonatal cloacas, trying to make a very accurate anatomic diagnosis during the newborn period is useless and may actually hurt the baby. — Alberto Peña (opinion) [Ep 4 · 17:26](https://origin-library.globalcastmd.com/watch/cloaca-workup-evaluation-683?t=1046)
- In the neonatal period, the crucial information is whether the baby has hydronephrosis, megaureters, or hydrocolpos compressing the ureters, which can be determined by ultrasound without endoscopy. — Alberto Peña (clinical) [Ep 4 · 17:29](https://origin-library.globalcastmd.com/watch/cloaca-workup-evaluation-683?t=1049)
- Knowing whether a neonate with cloaca has reflux is not crucial; the priority is decompressing the gastrointestinal and urogenital tracts. — Alberto Peña (opinion) [Ep 4 · 18:09](https://origin-library.globalcastmd.com/watch/cloaca-workup-evaluation-683?t=1089)

- The two critical endoscopic measurements are common channel length (from perineum to urethral takeoff) and urethral length (from urethral takeoff to bladder neck); urethral length determines the surgical approach. — Marc Levitt (clinical) [Ep 17 · 25:25](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=1525)
- Traditional classification uses 3 cm common channel length (≤3 cm straightforward, >3 cm complicated), but urethral length is equally important and not mentioned in published papers. — Marc Levitt (clinical) [Ep 17 · 25:27](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=1527)
- Endoscopy can falsely suggest the rectum is reachable when it is actually a long narrow fistula with healthy rectum high in the abdomen; contrast study (cloacogram) is needed to assess this. — Marc Levitt (clinical) [Ep 17 · 26:21](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=1581)
- 3D cloacogram reconstruction is superior to 2D fluoroscopy; experienced surgeons answer anatomy questions more correctly with 3D imaging, and printed 3D models may be even better. — Marc Levitt (clinical) [Ep 17 · 28:34](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=1714)

- Urogenital mobilization is appropriate when common channel is ≤3 cm AND urethral length above the takeoff is at least 1.5–2 cm; this leaves adequate urethral length after splitting the common channel. — Marc Levitt (clinical) [Ep 17 · 33:39](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=2019)
- With inadequate urethral length, do not perform total urogenital mobilization; instead leave the common channel to become the urethra and separate the vagina from it—a technically demanding operation. — Marc Levitt (clinical) [Ep 17 · 34:26](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=2066)

- Separating the vagina from the common channel and leaving the common channel as the entire urethra gives the patient about a 4 cm urethra, allowing intermittent catheterization and continence. — Marc Levitt (clinical) [Ep 17 · 36:05](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=2165)
- Type 1 cloaca (common channel ~1 cm with adequate urethral length): mobilize the vagina and leave the urethra slightly hypospadiac; patient will void if no neurogenic bladder component. — Marc Levitt (clinical) [Ep 17 · 36:40](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=2200)
- Patients with tethered cord or neurogenic bladder need a visible urethral orifice that is easily catheterized; slightly hypospadiac urethra is acceptable only if certain the patient will void and not need intermittent catheterization. — Marc Levitt (clinical) [Ep 17 · 37:11](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-299?t=2231)

- For vaginostomy tube placement, use an 8 or 10 French pigtail catheter from interventional radiology; a curled catheter prevents tube fallout as the hydrocolpos recedes, unlike straight catheters which fall out. — Marc Levitt (clinical) [Ep 9 · 14:15](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=855)
- For bilateral hydrocolpos, open into both vaginas at the dome, remove some of the common wall (septum), and one tube will drain both sides. — Marc Levitt (clinical) [Ep 9 · 13:27](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=807)
- The two critical endoscopic measurements are common channel length (traditional measure, with 3 cm or less being straightforward) and urethral length from urethral takeoff to bladder neck (newly emphasized measure that determines surgical approach). — Marc Levitt (clinical) [Ep 9 · 25:25](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=1525)
- Endoscopy can falsely suggest the rectum is reachable when it is actually a long narrow fistula with healthy rectum in the abdomen; a contrast study (cloacogram) is needed to determine this. — Marc Levitt (clinical) [Ep 9 · 26:21](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=1581)

- Urogenital mobilization, first described by Alberto Pena in 1996, mobilizes the urethra and vagina as a unit without operating on the wall between them, eliminating the 10% urethral-vaginal fistula rate from prior techniques. — Marc Levitt (clinical) [Ep 9 · 32:15](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=1935)
- Urogenital mobilization is appropriate when common channel is 3 cm or less AND there is at least 1.5-2 cm of urethra above the urethral takeoff; this leaves adequate urethral length after splitting the common channel. — Marc Levitt (clinical) [Ep 9 · 33:39](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2019)
- When urethral length is inadequate (less than 1.5 cm from takeoff to bladder neck), the common channel must be left alone to become the urethra, and the vagina must be separated from the common channel—a technically demanding operation. — Marc Levitt (clinical) [Ep 9 · 34:34](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2074)
- If urogenital mobilization is attempted with inadequate urethral length and the complex does not reach, the only option is abdominal delivery of the urogenital complex, which often does not work and can lead to urethral devascularization and loss. — Marc Levitt (clinical) [Ep 9 · 35:17](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2117)

- Separating the vagina from the common channel and leaving the common channel as the entire urethra gives the patient about a 4 cm urethra, allowing intermittent catheterization and continence. — Marc Levitt (clinical) [Ep 9 · 36:05](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2165)
- For type 1 cloaca (common channel of 1 cm with adequate urethral length), mobilizing the vagina alone and leaving a slightly hypospadiac urethra is acceptable if the patient will void and not require intermittent catheterization. — Marc Levitt (clinical) [Ep 9 · 36:40](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2200)

- Many cloaca patients have neurogenic bladder component whether or not they have tethered cord; a visible urethral orifice that is easily catheterized is needed if intermittent catheterization will be required. — Marc Levitt (clinical) [Ep 9 · 37:11](https://origin-library.globalcastmd.com/watch/cloaca-management-with-dr-marc-levitt-dr-aaron-garrison-957?t=2231)
- On ultrasound, the bladder is the first cystic structure seen from the abdominal cord insertion, outlined by umbilical arteries; a cystic structure posterior/inferior to the bladder reaching into the abdomen is hydrocolpos in a cloacal malformation. — Maria Cappels (clinical) [Ep 14 · 8:10](https://origin-library.globalcastmd.com/watch/prenatal-imaging-and-counseling-cloaca-and-complex-arms-2015-1021?t=490)

- In almost every cloaca, vesicostomy is unnecessary; the hydrocolpos must be drained, and perineal catheterization can relieve bladder outlet obstruction by decompressing the hydrocolpos and allowing ureters to drain. — Marc Levitt (guideline) [Ep 18 · 13:40](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=820)
- CIC frequency: initially three times daily in the NICU, then twice daily when families take over. Follow with serial ultrasounds every 2–3 days initially, then weekly, then monthly at home to confirm kidney decompression. — Richard Wood (guideline) [Ep 18 · 15:01](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=901)
- The goal of hydrocolpos drainage is kidney decompression. If kidneys are completely normal despite hydrocolpos, the hydrocolpos is not urgent; if kidneys are obstructed, drainage is critical. — Richard Wood (clinical) [Ep 18 · 15:01](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=901)

- 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 18 · 21:00](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=1260)
- For massive hydrocolpos requiring open vaginostomy, use a lower midline incision to get above the hydrocolpos, which is very adherent and inflamed against the anterior abdominal wall. A standard left lower quadrant incision will not provide adequate access. — Marc Levitt (clinical) [Ep 18 · 21:37](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-17-cloaca-part-1-4322?t=1297)

- Since implementing the measurement protocol, surgeons have never encountered a cloacal anatomy that differed from preoperative expectations. — Marc Levitt (clinical) [Ep 20 · 42:13](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-24-cloaca-part-3-5055?t=2533)
- The protocol has resulted in a significant reduction in the need for redo surgeries, likely because surgeons can define anatomy preoperatively and decide whether to proceed or refer. — Marc Levitt (clinical) [Ep 20 · 4:43](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-24-cloaca-part-3-5055?t=283)
- A patient with no anal opening and a single perineal orifice has a cloaca, not ambiguous genitalia or urogenital sinus. If the patient has a normal anus, then urogenital sinus or ambiguous genitalia can be discussed. — Marc Levitt (clinical) [Ep 21 · 4:03](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=243)

- The common channel in cloaca emanates just below the clitoral hood, which is not a typical location for the female urethra. — Marc Levitt (clinical) [Ep 21 · 4:40](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=280)
- Leaving the urethral opening in the clitoral location is suboptimal both cosmetically and functionally if the patient needs intermittent catheterization. — Marc Levitt (opinion) [Ep 21 · 5:04](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=304)
- In utero ascites in cloaca occurs when urine flows from the bladder into the vagina, cannot exit the common channel, and backs up through the fallopian tubes into the peritoneal cavity. — Marc Levitt (clinical) [Ep 21 · 8:08](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=488)
- The vast majority of hydrocolpos can be drained perineally; many times abdominal surgery is not needed to drain a hydrocolpos. — Marc Levitt (clinical) [Ep 21 · 9:01](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=541)
- When hydrocolpos is decompressed perineally, the bladder will suddenly dilate because there is less pressure on the distal ureters, allowing them to empty into the bladder. — Marc Levitt (clinical) [Ep 21 · 9:23](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=563)
- A vesicostomy in almost all cloacas is not the correct treatment because it will not solve the distal ureteral obstruction. — Marc Levitt (clinical) [Ep 21 · 9:46](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=586)

- The measurements vital in cystoscopy are the bladder neck location, the length of the common channel, and the length of the urethra. The urethral length must not be forgotten. — Marc Levitt (clinical) [Ep 21 · 12:10](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=730)

- Historically, total urogenital mobilization was done based on common channel measurement alone, but this was done in some cases for patients with inadequately lengthed urethra. — Marc Levitt (clinical) [Ep 21 · 12:34](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=754)
- Most low confluence cloacas have a long urethra, and when long means greater than 1.5 centimeters, which is needed for bladder function. — Marc Levitt (clinical) [Ep 21 · 13:23](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=803)
- You do not want to disrupt the urogenital diaphragm or pull the bladder neck down out of the urogenital diaphragm, as this will result in urinary leakage. — Marc Levitt (clinical) [Ep 21 · 13:31](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=811)
- For a patient with a 3.5 cm common channel and only 1.5 cm native urethra, the preference is to do rectal mobilization, vaginal mobilization, repair the back of the common channel, and leave the urethra to become 5 cm (native urethra plus common channel), which is more likely to result in a dry patient. — Marc Levitt (clinical) [Ep 21 · 14:01](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=841)
- The distinction between TUM versus UG separation is based on: common channel length (3 cm or less is low confluence, likely TUM; greater than 3 cm is high confluence, likely UG separation) and urethral length (if urethra cannot be guaranteed to be 1.5 cm or greater, must do UG separation). — Marc Levitt (clinical) [Ep 21 · 15:56](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=956)
- A study of patients who underwent VCUG because of UTI found them to have at least 1.5 cm, if not greater, urethral length, which is where the recommendation for minimum urethral length comes from. — Marc Levitt (clinical) [Ep 21 · 16:28](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=988)
- If you split a long common channel and there is very little urethra on the other side, you are essentially bringing the bladder neck down to the perineum, which must be avoided. — Marc Levitt (clinical) [Ep 21 · 17:19](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1039)
- A new technique involves making an incision in the posterior common channel to recess the urethral meatus below the clitoral hood for better cosmesis and catheterization access. — Marc Levitt (clinical) [Ep 21 · 19:19](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1159)
- Occasionally the vagina does not reach and requires vaginal replacement, ideally using a segment of sigmoid colon. — Marc Levitt (clinical) [Ep 21 · 20:18](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1218)
- A nice trick for vaginal replacement is to use the sigmoid colostomy site itself, taking a segment needed for vaginal replacement and then recreating the colostomy slightly more proximal. — Marc Levitt (clinical) [Ep 21 · 20:40](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1240)
- Tissue engineering for vaginal replacement is a key future endeavor; in theory, a tissue engineered vagina could be created from the patient's own stem cells over 3 months in the lab. — Marc Levitt (opinion) [Ep 21 · 21:17](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1277)
- The best time for cloacal correction is somewhere between 2 months and 1 year, with most repairs done at about 6 to 8 months of age. — Marc Levitt (clinical) [Ep 21 · 23:13](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1393)
- For a hypospadic urethra 1 cm away, you could consider leaving it hypospadic and doing only vaginal mobilization and introitoplasty, but must recognize the urethra might need catheterization one day, particularly if the patient has a spinal issue like tethered cord. — Marc Levitt (clinical) [Ep 21 · 18:28](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1108)
- The TUM itself may be needed just to mobilize the posterior vagina to get the introitus to reach comfortably. — Marc Levitt (clinical) [Ep 21 · 19:05](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1145)
- Fine needle cautery at low setting (usually 10, pure and spray for cut and coag) staying full thickness outside the TUM plane has not caused problems with stricture or fistula. — Marc Levitt (clinical) [Ep 21 · 25:51](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1551)
- Complications of PSARP are quite minimal with good technique, but rectal stricture can occur. When the vagina is mobilized and separated from the common channel, if under tension, vaginal stenosis can result. — Marc Levitt (clinical) [Ep 21 · 26:19](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1579)
- For vaginal stenosis after repair, as long as there is an opening, would not intervene at that point; would let the patient go through puberty and maybe consider an introitoplasty much later in life. — Marc Levitt (clinical) [Ep 21 · 26:45](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1605)
- For patients with greater than 3 cm common channel who undergo UG separation, 4 out of 5 (80%) will need intermittent catheterization. For those with 3 cm or less common channel, 1 out of 5 need intermittent catheterization. — Marc Levitt (epidemiological) [Ep 21 · 27:24](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1644)
- There is definitely increased mucus production with a bowel neovagina, so if it can be avoided, it should be, but it should be done if the vagina doesn't reach successfully to the perineum. — Marc Levitt (clinical) [Ep 21 · 28:19](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1699)
- There is some literature on pregnancy in cloacal patients. A few patients have become pregnant, and C-section is definitely advised because of the extensive perineal dissection. — Marc Levitt (clinical) [Ep 21 · 28:36](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1716)
- For stenotic vagina post-op, if the orifice is there, would leave the patient alone, let them go through puberty, and maybe do an introitoplasty later in life. — Marc Levitt (clinical) [Ep 21 · 29:05](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1745)
- If the vagina has disappeared post-op, a very good time to correct it might be at the time of colostomy closure when you can take the colostomy site itself and bring down a neovagina independently. — Marc Levitt (clinical) [Ep 21 · 29:17](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1757)
- The number of redo operations has dramatically reduced because surgeons are doing anatomy analysis first, doing it well, and not attempting complex cases they don't feel comfortable with. — Marc Levitt (opinion) [Ep 21 · 30:32](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1832)
- In the speaker's hands, TUM is a very straightforward case with very good results, virtually no vaginal stenosis, and a very good urethral repair. — Marc Levitt (opinion) [Ep 21 · 31:02](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1862)
- From a technical point of view, if dissecting the rectum and perineal body, vaginal replacement if needed should be done then, though it is much more difficult to do as a teenager. — Marc Levitt (clinical) [Ep 21 · 31:22](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1882)
- Vaginal switch operation is no longer done; those patients ended up with a lot of stenosis. — Marc Levitt (clinical) [Ep 21 · 32:14](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1934)
- Neovaginal dilatation is not done; would rather allow for a skin-level stenosis and later do an introitoplasty rather than subject the patient to vaginal dilatation. — Marc Levitt (clinical) [Ep 21 · 32:37](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1957)
- The perineal sphincter muscle complex is absolutely preserved during a posterior sagittal repair. — Marc Levitt (clinical) [Ep 21 · 32:54](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1974)
- For perineal vaginal drainage, the common channel may need catheterization 2 or 3 times per day. The baby may start to void between catheterizations, which can be followed on ultrasound. — Marc Levitt (clinical) [Ep 21 · 33:12](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=1992)
- Families are taught how to catheterize and brought to radiology to confirm by ultrasound that they are putting the perineal catheter in the correct location. Sometimes it needs to be directed right or left if there is bilateral hydrocolpos. A Coude catheter is useful because it can be twisted and directed. — Marc Levitt (clinical) [Ep 21 · 33:26](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2006)
- When doing UG separation, dissection starts on the back of the vagina as it enters the common channel, lifting it up off the common channel and dissecting the plane between vagina and posterior urethra. Do not touch the common channel at all to avoid getting into spongiosum tissue. — Marc Levitt (clinical) [Ep 21 · 34:09](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2049)
- Personal preference is to always start posterior sagittally if the confluence is low, below the peritoneal reflection. In the rare case where vagina and rectum are in the abdomen already, would start in the abdomen. — Marc Levitt (clinical) [Ep 21 · 35:25](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2125)
- 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. It's easier to start posterior sagittally and then go into the abdomen to continue that dissection. — Marc Levitt (clinical) [Ep 21 · 35:48](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2148)
- A TUM can always be done in prone position. If a TUM doesn't reach, can go into the abdomen, mobilize the confluence together, and pull through, but in such a case it would have been better to do a separation, not a TUM. — Marc Levitt (clinical) [Ep 21 · 36:36](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2196)
- The key to saving kidneys in cloaca is keeping the bladder empty through aggressive intermittent catheterization and bladder management, with vesicostomy in appropriate patients, particularly those with grade 4 or 5 reflux. This is learned from spina bifida management. — Marc Levitt (clinical) [Ep 21 · 38:10](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2290)
- Small bowel is the second choice after colon for neovagina. The blood supply of small bowel is quite tenuous and not as forgiving as that of colon. — Marc Levitt (clinical) [Ep 21 · 38:49](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2329)
- Personal preference is to do the entire cloacal operation together rather than staging the rectum first and doing UG mobilization later, though it is reasonable to do TUM later if it can be done perineally without touching the rectum. — Marc Levitt (opinion) [Ep 21 · 39:21](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2361)
- Perineal body length is individualized, measured from the bottom of the labia where they meet in the middle to the anterior limit of the anal sphincter. Everything in between is the perineal body. — Marc Levitt (clinical) [Ep 21 · 40:00](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2400)
- Hydrocolpos can recur after procedure if vaginal stenosis occurs. In that case, would dilate up the vaginal opening to allow flow. Usually vaginal stenosis is quite skin level and does allow drainage of mucus. — Marc Levitt (clinical) [Ep 21 · 40:32](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2432)
- There is rarely an occasion to close the bladder neck because most urethras are salvageable if you respect the principle of keeping the common channel intact to become the neourethra. They all have a smooth, catheterizable common channel, but you need to get the vagina off of it. — Marc Levitt (clinical) [Ep 21 · 40:57](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2457)
- Only in very rare circumstances of congenital urethral atresia, where the patient never was able to drain urine and drained urine out the fallopian tubes with in utero ascites, do those patients need vesicostomy at birth and ultimately a Mitrofanoff. — Marc Levitt (clinical) [Ep 21 · 41:32](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2492)
- Colon is preferred over small bowel for vaginal replacement for its more sturdy blood supply and because using the left colon at the colostomy site saves an anastomosis by taking the colostomy down and making a more proximal colostomy. — Marc Levitt (clinical) [Ep 21 · 43:58](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2638)
- Patients are plugged into the concept of transition at about age 12 because that's when girls are going through puberty and need gynecology colleagues. Officially at age 21 they no longer are seen at Children's Hospital, though can flex till about age 30 if needed. — Marc Levitt (clinical) [Ep 21 · 45:32](https://origin-library.globalcastmd.com/watch/ern-eurogen-arm-webinar-series-management-of-cloacal-malformations-what-is-new-i-6228?t=2732)
- In the previous technique for cloacal repair, the urethra and vagina were brought up to the introitus and separately anastomosed, resulting in poor definition of the vaginal vestibule and labia, often with skin separation between the urethra and vagina.

- Prior to the PSARP, an abdominal perineal pull-through was done for ARM (same concept as Hirschsprung's disease): throw the rectum away and pull the sigmoid down. That was wrong. (clinical) [Ep 29 · 13:48](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=828)
- In older ARM patients who had abdominal perineal pull-through, you see haustral markings at the anus and in the pelvis on contrast study because they pulled through sigmoid (the rectum has no haustral markings).

- A patient with sacral ratio of 0.45 has poor sacral development, so the perineum and musculature are probably not great, making them likely a bowel management candidate who will probably never achieve successful bowel control.

- Dr. Levitt's approach for this unique case would be to remove the entire mega-rectosigmoid, pull through the proximal sigmoid, make a well-sized anaplasty, and do a Malone at the same time. (opinion) [Ep 29 · 16:49](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=1009)

- For a redo PSARP with mega-rectosigmoid, Dr. Levitt would remove all the perineal rectum, dissect it out, go into the abdomen, dissect out the dilated segment, pull through the proximal sigmoid, close the posterior sagittal incision, and do a Malone.

- Dr. Geyer's plan is to try Malone only first, telling the family it might not succeed and more definitive surgery (removing colon) may be needed. — Chris Gayer (clinical) [Ep 29 · 18:49](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=1129)
- Very often a mega-rectosigmoid patient's anaplasty is not good (strictured, mislocated, or prolapsed), requiring redo of the anaplasty. (clinical) [Ep 29 · 19:24](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=1164)
- If the anus has only a stricture, making the anus bigger might give the colon a chance to decompress and improve. (clinical) [Ep 29 · 20:14](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=1214)
- If the mega-rectosigmoid is not strictured and is enormous, it was probably an inherent problem present since birth, and resection is appropriate. (clinical) [Ep 29 · 20:14](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-47-13846?t=1214)

- The more common scenario of anorectal malformation with absent vagina is a recto-vestibular fistula with completely normal urethra but no vagina in between—this is called recto-vestibular fistula with distal vaginal atresia, where the rectum ends as a fistula in the vestibule. — Marc Levitt (clinical) [Ep 30 · 6:37](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-40-13852?t=397)
- In this case, the rectum ended blind and quite high in the pelvis, making it unreachable through a posterior sagittal incision. — Marc Levitt (clinical) [Ep 30 · 7:08](https://origin-library.globalcastmd.com/watch/colorectal-quiz-episode-40-13852?t=428)
