Endoscopic treatment of Bouverets syndrome in an extremely elderly patient with Holmium: YAG laser.

Unlabelled: Bouveret's syndrome is a rare presentation of duodenal obstruction or gastric outlet obstruction caused by a large gallstone migrating through a cholecystoduodenal or choledochoduodenal fistula. Most patients are elderly and often have underlying comorbidities, complicating surgery. Endoscopic therapy should be used as first-line treatment for these patients who are not good surgical candidates. We report a case of a 98-year-old Chinese female who presented with vomiting for three days. Esophagogastroduodenoscopy and computed tomography confirmed the diagnosis of Bouveret's syndrome. The patient successfully underwent endoscopic lithotripsy with the Holmium: Yttrium- Aluminum-Garnet (Ho: YAG) laser. Ho: YAG laser lithotripsy has been used to treat Bouveret's syndrome in four case reports. It can be recommended in patients with Bouveret's syndrome who are poor candidates for surgery.
