A 45-year-old woman with morbid obesity (body mass index 44 kg/m²) presented to the emergency department with severe abdominal pain, nausea, vomiting and no defaecation. She had a laparoscopic adjustable gastric banding (LAGB) inserted elsewhere in 2006. No data or follow-up was performed postoperatively. A CT scan demonstrated a perforated LAGB through the gastric antrum (figure 1). Furthermore the connecting tube perforated the small intestine at the level of the proximal part of the jejunum with a partially intraluminally positioned banding (figure 2), causing prestenotic dilatation of the jejunum (figure 3). An upper gastrointestinal endoscopy confirmed an intact port site with a connected tube and migration and perforation of the band into the jejunum with an erosion of the gastric (figure 4) and duodenal wall. At closer inspection of the port site and connecting tube, we observed a high level of traction on the banding (figure 5). LAGB is a common bariatric procedure performed for the treatment of morbid obesity and is a restrictive procedure that compartmentalises the upper stomach by placing a tight, adjustable prosthetic band around the entrance of the stomach. Clinical diagnosis of postoperative complications is difficult because symptoms are often non-specific or even absent. Complications can be related either to the band such as slippage, erosion and pouch dilatation, or due to the connecting tube such as infection, disconnection or dislocation and migration.1 Band migration into the gastric wall is a well-known postoperative complication, connecting tube migration into the intestinal lumen is very rare though.2 A few cases have been described due to tube migration into the jejunal lumen or colonic lumen.2–4 In our case the tube migrated into the jejunal wall causing obstruction at the level of the proximal jejunum without disconnection from the port after a previous erosion and perforation of the gastric and duodenal wall. CT scan as well as endoscopy seem to be essential diagnostic tools in the evaluation of abdominal pain and obstruction due to band migration in order to observe previous erosion or perforation of the gastric or intestinal lumen. These complications should be considered even after many years of initial procedure. During an emergency laparotomy a gastrojejunal anastomosis was made after an intestinal resection of the distal duodenum and proximal jejunum. After 6 months an elective open gastric bypass was done, and 1 month later the patient regained a normal diet.
Complications such as erosion, perforation and migration of a laparoscopic adjustable gastric band (LAGB) should be carefully considered even after many years of initial procedure.
CT imaging as well as endoscopy can play a pivotal role in the diagnosis of a complication of an LAGB.
