The PPP - Perineal Body Preserving PSARP (Posterior Sagittal Anorectoplasty) for anorectal malformation with rectovestibular fistula in females - report of early outcomes.

Introduction The perineal body preserving PSARP (posterior sagittal anorectoplasty) (PPP) is a novel modification of the original PSARP for female patients with rectovestibular fistulas designed to eliminate the risk of perineal body dehiscence. This study aims to examine the outcomes following PPP. Methods A retrospective, single institution study was performed examining female patients with rectovestibular fistula who underwent PPP between 1/2020-12/2023. Exposure was done through the intended anoplasty only, there was no perineal body or posterior sagittal incision utilized. No routine post-operative dilations were performed. Post-operative outcomes, day of discharge, time to first feeding, and early stooling patterns were assessed. Results Fifteen patients underwent a PPP at a median age of six months (range 2 days-19 months) and median follow up of eleven months (range 1-36). Three (20%) patients underwent repair within the first three months of life. Five (33%) had diverting ostomies prior to referral to our team. There was no incidence of dehiscence or rectal prolapse. Two (13%) patients developed an anal stricture which required revision. Fourteen (93%) patients resumed normal feeds on post operative day one. Eleven (73%) were discharged on post operative day one. All patients were stooling spontaneously at their most recent clinical encounter with eleven (73%) utilizing laxatives. Conclusions The PPP eliminates the risk of perineal body dehiscence and has a quick return to regular diet and home. There is a 13% stricture rate which could relate to a difference in the distal rectal mobilization compared to the traditional PSARP.
