Laparoscopic management of symptomatic urachal remnants in adulthood

Abstract

The traditional surgical approach to the excision of persistent urachal remnants is a lower midline laparotomy or semicircular infraumbilical incision. The aim of this study is to report our experience with laparoscopic urachus excision as a minimally invasive diagnostic and surgical technique. This study was a prospective study involving patients who were diagnosed with persistent urachus and underwent laparoscopic excision. The morbidity, recovery, and outcomes of surgery were reviewed. Fourteen patients (8 men) with a mean age of 22.8±6.42 years underwent laparoscopic excision. All patients presented with discharge from the umbilicus. Although four patients had no sonographic evidence of a patent urachus, a diagnostic laparoscopy detected a patent urachus that was excised laparoscopically. One patient required laparoscopic reoperation for persistent discharge, and one patient presented with bladder injury, which was repaired via a small Pfannenstiel incision without any morbidity. The mean operative time was 71.1±0.28minutes, and the mean duration of hospital stay was 1.3±1.38 days. Pathological examination confirmed a benign urachal remnant in all cases. Laparoscopy is a useful alternative for the management of persistent or infected urachus, especially when its presence is clinically suspected despite the lack of sonographic evidence. The procedure is associated with low morbidity, although a small risk of bladder injury exists, particularly in cases of severe active inflammation. Recurrence is uncommon and was caused by inadequate excision of inflammatory tissue in our series that was easily managed laparoscopically.
