Abstract
BACKGROUND
A posterior urethral diverticulum (PUD) is a serious postoperative complication after anorectal malformation correction. Complete resection is technical demanding because of limited retrourethral working space deep in the pelvis.
OBJECTIVE
We pioneered the single-incision laparoscopic approach for PUD excision and evaluated the efficacy.
DESIGN, SETTING, AND PARTICIPANTS
Twenty-six PUD patients undergoing redo surgeries between June 2011 and June 2021 were reviewed.
SURGICAL PROCEDURE
A series of transabdominal retraction sutures were placed through the PUD to facilitate dissection. The contents were evacuated to create a working space. Distal PUD dissection was carried along the submucosal layer to prevent injury of the urethra/pelvic nerve complex. The rectal mucosa was peeled off from the junction site for complete PUD excision. The muscular cuff of the distal rectum was then oversewn.
MEASUREMENTS
Operative time, postoperative recovery, and complications were assessed.
RESULTS AND LIMITATIONS
The mean age of redo surgery was 2.46 yr. The average operative duration was 2.35 h. The mean postoperative hospital stay, resumption of full diet, and bowel movement were 10.23, 2.15, and 1.54 d, respectively. The median follow-up period was 46 mo (12-132 mo). No remnant of PUD, recurrent fistula, or urinary leak was detected. None of the patients had difficulty in urination, urinary dribbling, urinary tract infection, constipation, or soiling. All patients retained morning erection, and two postpubertal patients had ejaculations.
CONCLUSIONS
Our single-incision laparoscopic redo surgery provides an effective approach for PUD excision. It minimizes complications. It also preserves urinary and bowel continence and sexual function.
PATIENT SUMMARY
Complete resection of a posterior urethral diverticulum (PUD) in anorectal malformation is technically demanding because of limited retrourethral working space in the deep pelvis. The outcomes of single-incision laparoscopic PUD excision were satisfactory.
