Peritoneal oleogranulomatosis after laparoscopic gastric banding

Abstract

Laparoscopic adjustable gastric banding is one of the most frequently performed bariatric operations worldwide owing to its low incidence of iatrogenic complications. Peritoneal oleogranulomatosis, a sequelae of mineral oil contact with tissues, has not been reported in the context of bariatric surgery. We present the case of a 52-year-old woman with an incidental finding of peritoneal oleogranulomatosis at laparoscopic cholecystectomy, who had previously undergone laparoscopic gastric banding. A potential mechanism linking the two is postulated and the importance of histological diagnosis highlighted, given the macroscopic resemblance to carcinomatosis peritonei.
