Bouveret's syndrome, a rare and severe complication of gallstone disease, is characterized by gastric outlet obstruction resulting from the passage of a gallstone through a bilioenteric fistula, typically a cholecystoduodenal fistula. We present the case of a 68-year-old female patient with bilateral low back pain, nausea, vomiting, and constipation. Imaging revealed jejunal obstruction due to gallstone migration through a cholecystoduodenal fistula. Initial management involved nasogastric decompression and fluid resuscitation, followed by enterolithotomy. Diagnosis of Bouveret's syndrome is challenging due to nonspecific symptoms. Imaging, particularly computed tomography (CT), is essential for identifying Rigler's triad: pneumobilia, bowel obstruction, and ectopic gallstone. Early intervention is essential to avoid complications. This case highlights the complexity of diagnosing and managing Bouveret's syndrome. A high degree of clinical suspicion is essential for accurate diagnosis and timely treatment, ensuring the optimal management of Bouveret's syndrome.
