Mirizzi Syndrome With Bouveret Syndrome: A Rare Amalgam

Mirizzi and Bouveret syndromes are uncommon but important complications of calculous cholecystitis. Mirizzi syndrome commonly presents with jaundice due to extrinsic compression on the common bile duct by an impacted stone at the gall bladder infundibulum, whereas Bouveret syndrome presents with gastric outlet obstruction due to a large stone in the duodenum. Our case is a 65-year-old lady who presented with pain in the right upper abdomen associated with nausea and vomiting. Contrast-enhanced computed tomography and MRI of the abdomen were suggestive of calculus in the infundibulum of the gall bladder with compression over the common bile duct and a large stone in the first part of the duodenum. Upper gastrointestinal endoscopy confirmed the findings but could not retrieve the stone. Cholecystectomy with the retrieval of calculus from the infundibulum and duodenum was performed with the closure of the fistulous opening. The patient did well in the post-operative period and is doing well after nine months of follow-up. Chronic calculus cholecystitis can present in varied forms, and one should be aware of such rare complications and their management.
