Early onset Bouveret syndrome: a unique case in a young patient

Abstract

Abstract Background Bouveret syndrome is a rare etiology of gastric outlet obstruction, presenting with clinical manifestations that resemble those of several gastric pathologies. Timely diagnosis is imperative to mitigate potentially fatal consequences associated with this condition. Case presentation This case report involves a male patient, aged 35, who exhibited symptoms of intense abdominal discomfort, nausea, and vomiting over a 24-h period. The individual experienced identical symptoms of lesser intensity on three separate occasions throughout the preceding 4-month period, during which they resorted to analgesic medication for temporary relief. A contrast-enhanced computed tomography (CT) scan of the abdomen was performed, which identified the presence of the Rigler triad, characterized by pneumobilia, a cholecysto-antral fistula, and an ectopic gallstone lodged in the gastric antrum resulting in an obstruction. The patient’s diagnosis of Bouveret syndrome was determined based on the imaging findings. A surgical procedure known as cholecystectomy was conducted, which confirmed the existence of the sizable cholecystoduodenal fistula that was previously detected in the computed tomography (CT) scan. The surgical procedures that were conducted included a partial duodenectomy, a gastrojejunostomy, a cholecystectomy, and a common bile duct exploration with the removal of common bile duct stones. After examining the bile duct, a t-tube was inserted into the bile duct. Conclusion This case demonstrates a distinctive occurrence of a condition in a young man, typically observed in elderly females. There is a lack of established treatment guidelines for this particular entity. The appropriate course of action depends on various factors, including the patient’s condition, CT scan results, medical history, presence of co-existing illnesses, and intraoperative circumstances. These considerations are taken into account when determining whether a single-step surgical strategy or a multi-step approach should be pursued in order to minimize complications in patients. In this case, due to favorable conditions, a single-step approach was taken that yielded promising results.
