Laparoscopic extraperitoneal resection of urachal cyst

Remnant urachal cyst is a rare anomaly with an incidence of 1:5,000 and the majority are benign. The treatment of urachal cyst is complete surgical resection, and the cases of laparoscopic surgery for the resection have been reported since 1993. Most of the reports were about transabdominal laparoscopic approach, and it has been revealed that multiple skin incisions and trocar placements on upper abdomen were ineludible. With this condition, we are able to describe an extraperitoneal approach modified from total extraperitoneal herniorrhaphy, and to report a case of successful management of a urachal cyst by total extraperitoneal laparoscopic excision.
