An unusual case: Atypical localization of the gallbladder

We present a in a sixty-eight-year-old male patient with a congenital abnormality scheduled for metabolic surgery. The anomaly was characterized by the gallbladder’s unusual placement in the left lobe of the liver. Preoperative evaluations revealed no gallbladder pathology, but during metabolic surgery, we observed that the gallbladder was localized to the left lobe of the liver and adhered to the surrounding tissues. The case was considered as "acalculous cholecystitis," and the patient underwent cholecystectomy. The procedure progressed smoothly, and was successfully completed without complications, following the criteria for safe cholecystectomy. The biliary system is an area where anatomical variations are quite common; therefore, surgeons performing biliary surgery must have a thorough understanding of these variations. In order to avoid unintended injuries, it is beneficial to take certain technical precautions. When necessary, trocar insertion sites may be modified, and anterograde dissection can be performed. All anatomical structures should be clearly identified before clipping, and the cystic duct should be clipped as close to the infundibulum as possible.
