A Case of Duodenal Obstruction and Pancreatitis Due to Intragastric Balloon.

BACKGROUND Intragastric balloons have several advantages such as easy placement and low complication rates over other bariatric procedures. It is very rare for intragastric balloons to dislodge and give rise to pancreatitis. In this article, we present a case of duodenal obstruction caused by a gastric balloon leading to pancreatitis. CASE REPORT A 38-year-old obese female patient had undergone intragastric implantation one month before admission. The patient was admitted to our hospital because of sudden onset of abdominal pain. On the abdominal ultrasonography and tomography, edematous pancreatitis and cholelithiasis were observed. The patient was given medical treatment for pancreatitis. Abdominal ultrasonography was repeated on the next day, and a distended gallbladder was revealed. Thus, the patient was operated on with the pre-diagnosis of acute cholecystitis and biliary pancreatitis. Laparoscopic cholecystectomy was performed. During the operation, a hard and trapped object was determined in the second part of the duodenal lumen. The patient was reevaluated on the second postoperative day as her pain had increased. On direct abdominal X-ray and computed tomography scan, the tubular part of the gastric balloon was found to be stuck in the duodenum. A gastroscopy was performed, but the balloon could not be removed. Therefore, an immediate laparotomy was performed, and the balloon was removed via gastrotomy. CONCLUSION Although intragastric balloons are designed to reduce the risk of displacement, all unexpected patient complaints should lead to a thorough examination of the position and status of the balloon.
