Early lap-band erosion associated with colonic inflammation: a case report and literature review.

Overview

INTRODUCTION: Laparoscopic adjustable gastric banding is an effective and safe surgical modality for the treatment of morbid obesity. Erosion of the band into the stomach has been reported. No reports are available on erosion of the Lap-Band following diverticulitis of the colon. CASE REPORT: A 31-year-old female with a body mass index (BMI) of 52 underwent an uneventful laparoscopic Lap-Band placement. Postoperative contrast study revealed good positioning of the band and no evidence of leakage. The patient's recovery was uneventful except for an elevated temperature of 101.5 degrees F that was attributed to her atelectasis. She had lost 52 lbs. and remained asymptomatic for 3 months. Following this period of successful weight loss, she presented with complaints of abdominal pain for 3 days associated with diarrhea of 7 days' duration. A Gastrografin contrast study showed no evidence of a leak or band slippage but erosion was suspected. Upper endoscopy confirmed erosion of the band into the stomach. Computed tomography (CT) of the abdomen revealed thickening of the sigmoid and descending colon with mesenteric fat stranding consistent with diverticulitis. Laparoscopic removal of the Lap-Band system was performed. CONCLUSION: We postulate that colonic diverticulitis could have been a precipitating factor in the development of band erosion. Intraabdominal sepsis resulting in subacute infection of the Lab-Band system may be the underlying factor.
