A case report of incisional hernia through a 5 mm lateral port site following laparoscopic cholecystectomy

INTRODUCTION: Less than 10 mm port-site herniation is a rare complication after laparoscopic surgery. We report a case of complicated herniation through the 5-mm lateral trocar port site. CASE REPORT: A 63-year old obese female was admitted due to intestinal obstruction. She has undergone the laparoscopic cholecystectomy 1 year ago. On examination, abdomen was bloated and roughly 10 cm size mass was palpable on the right subcostal area. Plane radiogram of the abdomen showed signs of intestinal obstruction. Since conservative treatment was ineffective, the patient was operated on. The laparotomy revealed a protrusion of a part of right large intestine and greater omentum into the subcutaneous space through the abdominal wall defect below right subcostal margin. There was a dilatation of intestines proximally incarcerated colon. It was released and a part of omentum was resected. The peritoneum and fascia-muscular defect was closed by interrupted vicryl sutures. CONCLUSION: Acute herniation through a 5 mm size most lateral trocar port site is a rare complication of laparoscopic surgery requiring prompt differential diagnosis.
