A Case Report of Gastric Outlet Obstruction Due to Gall Bladder Distension from Acute Cholecystitis

ABSTRACT

Gastric outlet obstruction (GOO) is a disease that causes pyloric canal or duodenal atresia by various etiologies. It is mainly caused by malignancy or peptic ulcer and rarely caused by corrosive injury, gastric polyp, pyloric stenosis, bezoar, or biliary stone. We report a rare case of GOO due to unreported etiology. A 74-year-old male patient with medical history of hypertension, diabetes mellitus, and stroke came to the emergency medical center with a chief complaint of acute stomachache. On abdominal computed tomography, it was diagnosed as GOO due to gall bladder distension from acute cholecystitis. During conservative treatment and antibiotics administration, gastrofibroscopy and magnetic resonance cholangiopancreatography was performed to determine other etiologies; however, the final diagnosis was made as acute cholecystitis. After laparoscopic cholecystectomy, he was discharged without specific complications. On a pathology examination postoperation, there was no specific diagnosis, except for acute cholecystitis. Gastric outlet obstruction is caused by various etiologies, with the course of treatment being dependent on the specific etiology. We report a rare case of GOO caused by gall bladder distension due to acute cholecystitis. Various etiologies should be considered carefully to include even the rare etiologies for choosing the correct treatment.
