Laparoscopic posterior rectopexy (Well's procedure) for full-thickness rectal prolapse following laparoscopic repair of an anorectal malformation: A case report.

INTRODUCTION: Intractable full-thickness rectal prolapse (IRP) unresponsive to conservative treatment remains a major problem after anorectoplasty for high or intermediate anorectal malformation (ARM). Surgical management must aim for a permanent fixation of the rectum to the presacral fascia. While in children with IRP following ARM repair the optimal procedure has not been established yet, laparoscopic posterior mesh-rectopexy (Well's procedure) has demonstrated efficacy in adults.

PRESENTATION OF CASE: A male infant with intermediate ARM received laparoscopic-assisted anorectal pull-through at the age of 4 months. Three months later he developed mucosal prolapse and received multimodal conservative treatment. Because of progression into a full-thickness RP with ulcerations, the parents opted for surgical management. Well's procedure was performed at the age of 4 years. Using four ports, the rectum was circumferentially mobilized down to the pelvic floor and pulled inside. A 5 × 5 cm prolene mesh was tacked to the sacrum, enveloped posteriorly 270° around the rectum, fixed with interrupted prolene sutures on both edges and carefully covered with peritoneum. Any redundant external mucosa was excised from a perineal approach. There were no intra- and postoperative complications. Within 1.5 years of follow-up the boy had voluntary bowel movements and was toilet trained. No prolapse recurrence could be observed nor provoked.

DISCUSSION: We present the first pediatric case of IRP secondary to laparoscopic ARM repair which has been successfully treated by combined Well's procedure and perineal mucosal resection.

CONCLUSION: Well's procedure is a successful technique and should be further explored in children with ARM and IRP.
