Acute pancreatitis after intragastric balloon insertion: case report

Abstract

The intragastric balloon (IGB) is a relatively recent non-surgical weight loss technique that is now widely used in the world to treat obesity. However, IGB causes a wide range of adverse effects that range from minor ones, such as nausea, stomach pain and gastroesophageal reflux, to serious ones, such as ulceration, perforation, intestinal blockage and compression of adjusting structures. A 22-year-old Saudi woman presented to the emergency department (ED) with a history of upper abdominal pain that started 1 day before admission. The patient's surgical background was unremarkable, and no other obvious pancreatitis risk factors were present. The patient underwent a minimally invasive treatment after being diagnosed with obesity (class 1), in which an IGB was inserted one and a half months prior to her ED presentation. She consequently began to lose weight (around 3kg). The hypothesis states that pancreatitis following IGB insertion can be caused either by stomach distention and pancreatic compression at the tail or body or by ampulla obstruction due to balloon catheter migration at the duodenum. Heavy meal consumption, which may cause an increase in pancreatic compression, is another potential cause of pancreatitis in such patients. We believe that the IGB-induced compression of the pancreas at its tail or body was the likely cause of pancreatitis in our case. This case was reported because it is the first one from our city as far as we know. A few cases from Saudi Arabia have also been reported, and reporting them will help to improve doctors' awareness of this complication, which can cause pancreatitis symptoms to be mistaken for something else because of the balloon-related effects on gastric distention.
