Bouveret syndrome: A fatal diagnostic dilemma of gastric outlet obstruction.

The patient presented in this study was a 54-year-old woman complaining of nausea and vomiting, onset preceding four days, with no significant past medical history and an unremarkable surgical history. The patient was afebrile and hypertensive. Physical examination revealed a non-tender abdomen, and initial laboratory evaluation revealed elevated blood glucose level, ketonuria, leukocytosis, elevated C-reactive protein, gamma glutamyl transferase, lactate dehydrogenase, and total bilirubin. The patient was admitted to the internal medicine ward due to new onset of diabetes mellitus. Due to persistent nausea and vomiting, gastroscopy revealed a healed duodenal ulcer, and abdominal ultrasonography revealed cholelithiasis. The medical condition of the patient deteriorated further in the internal medicine ward, with impending hypotension, tachycardia, leukocytosis, and acute renal failure, and she was admitted to the intensive care unit due to septic shock. A computerized tomography was obtained, which revealed an impacted gallstone in the distal duodenum. The patient was taken to the operating room. The gallstone was encountered in proximal jejunum immediately distal to the ligament of Treitz. A longitudinal enterotomy was made, and the stone was extracted. Her drains were cleared on postoperative day 5, and gastrointestinal function returned to normal. Unfortunately, the patient developed an overwhelming sepsis due to bacteremia and fungemia, and died on post-operative day 19.
