Topic Overview

A surgical conference session on female anorectal malformations covering diagnosis, operative technique, and management of complications. The discussion emphasizes the critical importance of complete anterior rectal wall mobilization to prevent perineal body dehiscence, with debate over whether to mobilize just enough for tension-free reach versus ensuring complete separation from the vagina. Speakers address management of associated anomalies including vaginal agenesis (which carries 75% risk of urologic problems), vaginal septa, and cloaca with hydrocolpos. The session includes audience polling on clinical decisions and highlights the lack of prospective data for many perioperative management questions.

Key Takeaways

  • Incomplete anterior rectal mobilization causes perineal body dehiscence in female ARM redos; dissect completely to vaginal separation. (6:38)
  • 75% of patients with vaginal agenesis have urologic problems; 50% develop CKD stage 3+. Evaluate kidneys early and monitor long-term. (37:13)
  • For newborn cloaca with hydrocolpos: divided colostomy + pigtail catheter decompression. Defer cystoscopy/vaginoscopy to 2-3 months. (46:09)
  • Hydrocolpos creates vicious cycle: vaginal distension obstructs urethra, causing urine reflux into vagina, worsening distension. (50:28)
  • Vaginal septum resection in adolescents is straightforward; use electrocautery and approach cervix closely without injury. (31:29)

Chapters

  • 0:00Introduction and Perineal vs Vestibular Fistula Diagnosis — Opening announcements followed by audience polling on distinguishing perineal from vestibular fistulas using clinical photographs. Discussion of proper examination technique holding labia up and out.
  • 10:00Mobilization Technique and Extent of Dissection Debate — Panel debate on how much anterior rectal wall mobilization is necessary. Don advocates mobilizing just enough to reach without tension; Ivo and Michael argue for complete separation from vagina despite losing internal sphincter tissue. Mark notes finding undissected areolar plane in every female redo.
  • 20:00Perioperative Management Controversies — Discussion of NPO duration (Mark keeps patients NPO 6-7 days until perineal body heals), use of Foley catheters, bowel preparation protocols, and the need for prospective trials. Kate Deans introduces concept of rapid learning healthcare systems.
  • 30:00Vaginal Anomalies: Septa and Agenesis — Management of vaginal septa (Jerry notes patients often asymptomatic with intercourse but have tampon difficulties). Vestibular fistula with absent vagina requires sigmoid neovagina; 75% have urologic problems including 50% with CKD stage 3 or greater per Shamel's 2009 series.
  • 40:00Cloaca and Hydrocolpos Management — Newborn cloaca with hydrocolpos management: divided colostomy with pigtail catheter decompression versus vaginostomy. Discussion of laparoscopic approach, intermittent catheterization under ultrasound guidance, and physiology of hydrocolpos compressing ureters.
  • 50:00Final Questions and Closing — Question about difficulty mobilizing vagina after vaginostomy tube placement. Announcements about lab forms and closing remarks.

Key claims

  • 6:38In every single female redo, undissected areolar tissue is found that had never been dissected by the original surgeon — Mark
  • 7:09If anterior rectal wall is not free enough it can pull back and disrupt the perineal body — Mark
  • 7:51Many female redos were done without colostomy in the newborn period — Mark
  • 11:35The vast majority of common perineal grooves, if observed, will become normal skin over time — Mark
  • 14:12Rectal blood supply is intramural, so injuring the rectal wall hurts its blood supply — Mark
  • 14:36Coming in from lateral to anterior is key; the lateral defines the anterior plane — Mark
  • 15:25The more proximal you are, the easier rectum and vagina are to separate — Mark
  • 17:27Mark keeps patients NPO until perineal body is healed, usually around day 6 or 7 — Mark
  • 18:17Can use 10% dextrose for NPO period instead of hyperalimentation in healthy robust children — Mark
  • 19:54Systematic review shows early enteral nutrition seems better than later nutrition, but all studies are retrospective and poor quality — Mark
  • 30:15Women with longitudinal vaginal septa often learn to use one side more than the other and are not really bothered with intercourse — Mark
  • 30:53Women with vaginal septa often have tampon difficulties - can't use them, need one in each side, or need tampon plus pad — Mark
  • 31:29Resecting vaginal septum in adolescent is not hard; use electricity and get as close to cervix as possible without damaging it — Mark
  • 27:40About 2-5% of vestibular fistulas have a vaginal septum — Mark
  • 37:13Of 33 patients with absent vagina, 75% had urologic problems including neurogenic bladder — Shamel
  • 37:26Of patients with absent vagina, 50% had CKD stage 3 or greater — Shamel
  • 37:31Solitary kidneys, reflux, hydronephrosis, neurogenic bladder, and UTIs are long-term sequelae in absent vagina cohort — Shamel
  • 38:17Rectum separates very nicely from urethra in absent vagina cases - thick fibrous tissue, not as adherent as rectum to posterior vagina — Mark
  • 39:35Ideal time to fix vagina is when fixing rectum because perineal body is open — Mark
  • 39:42Neovagina pedicle reaches much easier when child is young and doesn't have as long a pelvis — Mark
  • 46:09For newborn cloaca with hydrocolpos, do open divided colostomy and decompress vagina with pigtail catheter rather than formal vaginostomy — Mark
  • 46:48Doing cystoscopy at time of colostomy creation in cloaca patient makes colostomy creation very difficult — Mark
  • 47:20No rush to scope vagina in newborn period; better to wait until 2-3 months for better visualization — Mark
  • 50:02With hydrocolpos, straight tubes fall out at about 2 months when inflammation recedes; use curled tube instead — Mark
  • 50:28Much of hydrocolpos fluid can be urine refluxing up, not just vaginal secretions — Mark
  • 51:37As vagina distends it obstructs urethra, resulting in more urine going into vagina - cycle perpetuates itself — Mark
  • 52:08Catheter can go into right vagina, left vagina, bladder, or rectum - need ultrasound guidance to ensure draining correct structure — Mark
  • 53:50Once hydrocolpos is drained, bladder fills beautifully, demonstrating that hydrocolpos compresses ureters — Mark

Points of disagreement

  • 3:13Extent of anterior rectal wall mobilization in vestibular fistula repair
    • Mark: Mobilize just enough so rectum reaches perineal skin with a little tension, then quit
    • Mark: Completely separate rectum from vagina even though it means losing some internal sphincter tissue, to prevent wound problems and retraction
  • 16:36Duration of NPO period after primary vestibular repair without colostomy
    • Mark: Wait 6-7 days until perineal body is healed to allow intervention before dehiscence
    • Mark: Feed earlier (4 days or less) based on wound appearance
  • 26:33Use of Foley catheter in vestibular/perineal fistula repair
    • Mark: Never use Foley; urine leaking on perineum is not a big deal
    • Mark: Always use Foley to keep alkaline urine away from fresh wound
  • 42:08Timing of vaginal septum resection
    • Mark: No rush if premenarchal; wait until puberty unless another operation is planned
    • Mark: Ideal time is during rectal repair when perineal body is open

Open questions

  • What is the optimal duration of NPO period after primary vestibular repair without colostomy?
  • Should all vestibular fistulas undergo formal vaginoscopy or only visual inspection of introitus?
  • Is complete rectal-vaginal separation necessary or is mobilization to tension-free reach sufficient?
  • What is the role of prospective randomized trials versus rapid learning healthcare systems in rare pediatric surgical conditions?
  • Should vaginal septa be resected at time of rectal repair or deferred until puberty?
