Management of intestinal obstruction following laparoscopic donor nephrectomy

Transmesenteric Internal Herniation Leading to Small Bowel Obstruction Postlaparoscopic Radical Nephrectomy

Internal herniation following laparoscopic surgery is rare. We present a case of small bowel obstruction secondary to internal herniation in a 76-year-old male patient. Presentation was on postoperative day 28 following transperitoneal laparoscopic radical left nephrectomy for suspected renal carcinoma. The herniation was through a defect in the large bowel mesentery identified at exploratory laparotomy. To date, 10 cases of internal herniation following laparoscopic nephrectomy have been described in the literature. Two cases were managed laparoscopically and the remainder by laparotomy. One case required resection of an ischaemic portion small bowel and the remainder were managed by reduction of the hernia and closure of the defect. Internal herniation is rare but carries significant morbidity. It must be considered in cases presenting with obstructive symptoms after laparoscopic nephrectomy. Early CT scanning and prompt surgical management are hallmarks of best management.
