Laparoscopic reoperation of the bile duct in a patient with situs inversus totalis: a case report.

Situs inversus totalis is a rare congenital anomaly, where the positions of major internal organs are reversed from their normal arrangement. This anatomical abnormality significantly increases the complexity of surgeries, especially in laparoscopic reoperations of the bile duct for patients with a history of abdominal surgery. Traditional anatomical landmarks and surgical steps need to be adjusted according to the patient's unique anatomy. This not only makes intraoperative identification of structures more challenging but also introduces greater uncertainty during the procedure. This case report summarizes the successful laparoscopic reoperation of the bile duct in a patient with situs inversus totalis, providing important reference and guidance for future similar procedures.
