Large postoperative umbilical hernia following laparoscopic cholecystectomy. A case report.

The authors report a case of large postoperative umbilical hernia following laparoscopic cholecystectomy, which occurred in the early postoperative period despite primary suture of the trocar insertion site. Forced dilation of the fascial layer is proposed as the etiological mechanism. This procedure should be avoided and an accurate and aseptic removal of the gallbladder should be performed in order to prevent risk of abdominal wall weakness and visceral herniation.
