title: Parastomal hernia incarceration due to migrated intragastric balloon.
abstract: The temporary placement of intragastric balloons is a common method to achieve rapid weight loss before planned metabolic surgery. We report the case of a 48-year-old morbidly obese patient. Ten years ago the patient underwent emergency sigmoidectomy with creation of a double-barreled ileostomy for perforated diverticulitis. Over time he developed a giant parastomal hernia. For preoperative weight reduction before planned restoration of intestinal continuity, an intragastric balloon was inserted 3 years ago. The patient was admitted to our emergency department with peritonism and a septic shock. After computed tomography showing small bowel ileus, laparotomy was performed, revealing marked ischemia of incarcerated small and large intestine. Only postoperatively was the intragastric balloon found in the resected small bowel, causing a mechanical ileus with consecutive incarceration of the bowel. We review the literature on complications due to the migration of intragastric balloons. This clinical case gives a fair warning of the possible deleterious outcome of intragastric balloons, especially in hernia patients.
