A case of Bouveret's syndrome treated with gastrojejunal anastomosis

Bouveret's syndrome is a rare cause of proximal gallstone ileus with obstruction of duodenum or gastric outlet. We report a case of an 87-year-old female patient presented with 1 week history of vomiting whose plain radiograms showed ileus and pneumobilia. The abdominal computed tomography confirmed pneumobilia and revealed free air and leakage of oral contrast agent in the hepatic hilum and subhepatic space and an impacted gallstone in the third portion of the duodenum. The patient underwent exploratory laparotomy, which showed that the duodenal perforation was circumvallated, and a side-to-side retrocolic gastrojejunal anastomosis was performed in order to surpass the impacted gallstone. Removal of the impacted gallstone through enterotomy or gastrotomy or endoscopic lithotripsy is the usual treatment of Bouveret's syndrome. However, gastrojejunal bypass may be a treatment option when the patient undergoes laparotomy and the gallstone is impacted in the third or fourth portion of the duodenum.
