Abstract:
Accurate identification of anatomical variations in the biliary tree is crucial in hepatobiliary surgeries, including the widely performed laparoscopic cholecystectomy. Coexisting anomalies, though rare, present challenges for surgeons. This case study follows a 43-year-old female post-sleeve gastrectomy, diagnosed with mild gallstone pancreatitis and choledocholithiasis, who underwent early cholecystectomy. Intraoperatively, a 3 mm aberrant right hepatic duct and three 1 mm subvesicular ducts were identified. Recognizing these variants is pivotal for surgical success. Utilizing preoperative imaging, intraoperative vigilance, and advanced techniques like cholangiography are essential in preventing complications. Continuous education and collaborative experiences among surgical teams are integral in enhancing patient safety in these complex procedures.
