摘要

Laparoscopic resection of giant hilar biliary cystadenoma has been rarely documented in clinical literature. Here, we report a case of a 51-year-old female patient whose laboratory results were unremarkable, while abdominal imaging identified a large cystic lesion located in the hepatic hilum. The patient underwent laparoscopic tumor resection under general anesthesia. During surgery, the tumor was noted to significantly compress nearby hilar structures—including the portal vein and gallbladder—and had a communication with the left hepatic duct. The tumor was successfully resected en bloc, and pathological analysis confirmed it to be a hilar biliary cystadenoma. Postoperatively, the patient recovered uneventfully without any complications and was discharged in good condition. No tumor recurrence was detected at the 6-month follow-up visit. This case underscores the potential for misdiagnosis of large hilar biliary cystadenomas and shows that laparoscopic resection is a viable therapeutic option for these lesions.
