Gastropleural Fistula Presenting as a Complication of Gastric Sleeve Surgery: A Case Report

A rare complication of sleeve gastrectomy surgery is gastropleural fistulas (GPF), where a fistula develops between the stomach and the pleural cavity. This complication can be debilitating and present with many nonspecific symptoms making it hard to diagnose. This is a case report of a 45-year-old female who underwent robotic-assisted gastric sleeve revision after developing a GPF as a complication of her gastric sleeve six years later. This led to the development of a recurrent subdiaphragmatic abscess in the left upper quadrant. Before presenting to us, she underwent multiple hospitalizations and received numerous endoscopic stent treatments. However, the abscess continued to recur. Given her recurrent abscess, she consented to gastric sleeve revision. GPFs are amongst the rarest complications, with only 76 reported cases. Since this complication can cause shock, early diagnosis and treatment are necessary to improve patient outcomes and reduce morbidity.
