title: [A case of gallstone ileus treated with electrohydraulic lithotripsy guided by colonoscopy].
abstract: A 63-year-old woman was admitted to the hospital with abdominal pain and nausea. Her abdomen was distended with obstructive bowel sounds on exam. There was diffuse abdominal tenderness but no palpable masses. Abdominal computed tomography (CT) scan revealed a large gallstone in the ileum. Surgical intervention was deferred given patient's known significant liver cirrhosis (Child-Pugh class B). Instead colonoscopy was performed and a large gallstone was found to be impacted at the ileocecal valve. The gallstone was fragmented using electrohydraulic lithotripsy (EHL) and then retrieved with snare and forceps. The patient made a full recovery and was eventually discharged home. This is the first reported case of an impacted gallstone at the ileocecal valve with successful colonoscopic treatment using electrohydraulic lithotripsy in Korea. This case highlights the potential therapeutic benefits for colonscopic retrieval of a gallstone impacted at the ileocecal valve in well selected individuals.
