Acute pancreatitis caused by gastric balloon: a case report.

ABSTRACT

Background: Intragastric balloon (IGB) insertion is a safe and effective method for the treatment of obesity. The most common side effects of the balloon-therapy are nausea/vomiting and abdominal pain, acute pancreatitis has rarely been reported. Case Description We present the case of a 28-year-old woman who underwent IGB insertion 9 months before onset of intense upper abdominal pain. We confirmed the diagnosis of acute pancreatitis by means of clinical symptoms, serological tests and cross-sectional imaging. Endoscopic removal of the balloon led to a complete resolution of the symptoms. Initial laboratory parameters were normal on admission, only the control of lipase and amylase levels led us to the diagnosis of pancreatitis. On imaging with computed tomography, the filling catheter of the balloon showed to be dislodged in the duodenum. After carrying out a systematic approach, other causes of pancreatitis were ruled out. Conclusions: Laboratory tests including amylase/lipase and adequate imaging should be considered in patients with relevant symptoms after gastric balloon insertion. A possible pathogenesis may be the direct compression and traumatic effect on the pancreas by the balloon or the dislodgement of the catheter into the duodenum and an obstruction/compression of the Papilla. Endoscopic removal of the balloon is not mandatory in every case, it should be decided individually.
