Multidisciplinary approach to evaluation of rectovaginal fistulas.

Thorough evaluation of a rectovaginal fistula is essential to optimize surgical repair. The underlying cause should be addressed and treated, which can affect the timing and the approach to repair. It is imperative to be well prepared because the highest chance of successful closure occurs during the initial repair attempt. Our objective was to demonstrate how multidisciplinary colorectal surgery and urogynecology teams use specific methods during the examination under anesthesia to evaluate a complex rectovaginal fistula and to optimize the surgical approach to repair. Anesthesia may be provided with monitored anesthesia care and a posterior perineal block. This pain control allows for a wide range of techniques to evaluate the fistula using anoscopy, fistula probe, hydrogen peroxide, and sigmoidoscopy. In addition, the teams show how curettage and subsequent seton placement can encourage closure by secondary intention and decrease the risk of abscess formation, respectively.

Mohs surgery for female genital Paget's disease: a prospective observational trial.

BACKGROUND: Extramammary Paget's disease recurs often after traditional surgical excision. Margin-controlled surgery improves the recurrence rate for male genital disease but is less studied for female anatomy. OBJECTIVE: This study aimed to compare surgical and oncologic outcomes of margin-controlled surgery vs traditional surgical excision for female genital Paget's disease. STUDY DESIGN: We conducted a prospective observational trial of patients with vulvar or perianal Paget's disease treated with surgical excision guided by Mohs micrographic surgery between 2018 and 2022. The multidisciplinary protocol consisted of office-based scouting biopsies and modified Mohs surgery followed by surgical excision with wound closure under general anesthesia. Modified Mohs surgery cleared peripheral disease margins using a moat technique with cytokeratin 7 staining. Medial disease margins (the clitoris, urethra, vagina, and anus) were assessed using a hybrid of Mohs surgery and intraoperative frozen sections. Surgical and oncologic outcomes were compared with the outcomes of a retrospective cohort of patients who underwent traditional surgical excision. The primary outcome was 3-year recurrence-free survival. RESULTS: Three-year recurrence-free survival was 93.3% for Mohs-guided excision (n=24; 95% confidence interval, 81.5%-100.0%) compared to 65.9% for traditional excision (n=63; 95% confidence interval, 54.2%-80.0%) (P=.04). The maximum diameter of the excisional specimen was similar between groups (median, 11.3 vs 9.5 cm; P=.17), but complex reconstructive procedures were more common with the Mohs-guided approach (66.7% vs 30.2%; P<.01). Peripheral margin clearance was universally achieved with modified Mohs surgery, but positive medial margins were noted in 9 patients. Reasons included intentional organ sparing and poor performance of intraoperative hematoxylin and eosin frozen sections without cytokeratin 7. Grade 3 or higher postoperative complications were rare (0.0% for Mohs-guided excision vs 2.4% for traditional excision; P=.99). CONCLUSION: Margin control with modified Mohs surgery significantly improved short-term recurrence-free survival after surgical excision for female genital Paget's disease. Use on medial anatomic structures (the clitoris, urethra, vagina, and anus) is challenging, and further optimization is needed for margin control in these areas. Mohs-guided surgical excision requires specialized, collaborative care and may be best accomplished at designated referral centers.

New neovagina-creating technique on the basis of a fasciocutaneous flap for Müllerian agenesis.

OBJECTIVE: To present a new surgical technique on the basis of an internal thigh fasciocutaneous flap for generating a compliant and sensitive neovagina with preservation of the external genitalia. DESIGN: Video demonstration of the surgical steps. PATIENT(S): An 18-year-old woman with Müllerian agenesis confirmed at ultrasound and magnetic resonance imaging. The residual vagina was 3 cm long and 1.5 cm wide. After counseling by a gynecologist and plastic surgeon, in which all available techniques with pros and cons were exposed, the patient opted for the new technique. The long time required by conservative approaches and the desire to preserve the external genitalia with the chance to have a sensitive vagina guided the choice. INTERVENTION(S): The cul-de-sac of the vaginal stump was incised transversally. A 4-cm-wide and 9-cm-long canal bounded anteriorly by the bladder, posteriorly by the rectum, and superiorly by the peritoneum of Douglas was developed by blunt dissection. Fasciocutaneous flaps of 12 per 5 cm on the anteromedial aspect of the thighs were developed, identifying the vascular-from the pudendal artery-and nervous pedicles. A tunnel between the flap pedicles and neovagina introitus was created between fascia and subcutaneous tissue, detaching the vulvar structures from the ischiopubic ramus. Flaps were tunneled up to the neovagina introitus and sutured together by interrupted suture to form a tube with outside skin. The flaps were transposed into the canal everting the tube to obtain the skin lining the internal neovagina. The inferior margins of the flaps were sutured to the vaginal stump mucosa. No internal stitches were placed. Antibiotic prophylaxis was used during surgery. The entire procedure lasted 6 hours. During the postoperative period, no special positioning or ambulation restrictions were used. MAIN OUTCOME MEASURE(S): Compliance and sensitivity of the neovagina, esthetic result, and perioperative and long-term complications. RESULT(S): The postoperative course was uneventful, with early mobilization. The length of hospital stay was 16 days to allow proper vaginal dilator use; initial daily followed by intermittent use was planned. At a 2-year follow-up, the neovagina was sensitive and patent, allowing sexual intercourse. No complications were reported, and the patient was satisfied with the functional and esthetic result. CONCLUSION(S): The new surgical technique was feasible and effective, preserving the external genitalia and avoiding graft healing and bowel secretion drawbacks without an intra-abdominal surgical step and related risks. However, more cases-2 cases performed to date with similar results-and long-term follow-up are needed to confirm the efficacy. In this regard, the regular use of vaginal dilators and forecast adherence between flaps and the connective tissue of the bladder and rectum are expected to prevent neovagina prolapse without any anchoring to the pelvic structures.

Multidisciplinary management of adult cloacal exstrophy complications: A challenging case of nephrolithiasis and abdominal wall extrusion of a catheterizable ileal pouch.

Cloacal exstrophy is a rare congenital syndrome which comprises multiple genitourinary, gastrointestinal and musculoskeletal anomalies. The long-term effects following childhood cloacal exstrophy management is poorly characterized in living adults. In this report, a 42-year-old female born with cloacal exstrophy presented after numerous prior surgical reconstructions with abdominal extrusion of a catheterizable ileal pouch and bilateral staghorn calculi. We review the steps in surgical management of this uncommon scenario with a goal of improving the patient's quality of life.
