Posterior approach to Calot’s triangle in situs inversus totalis: A case report and review of literature

Figure 1 Preoperative imaging confirming situs inversus totalis. A: Chest computed tomography showing dextrocardia; B: Magnetic resonance cholangiopancreatography demonstrating cholelithiasis and situs inversus totalis.

Figure 2 Illustrates the operative setup and key steps in the posterior dissection of Calot’s triangle. A: Schematic diagram of laparoscopic port placement; B: Gallbladder located left of the falciform ligament with dense adhesions to the greater omentum; C: Posterior dissection of the cystic duct in Calot’s triangle; D: Posterior dissection of the cystic artery in Calot’s triangle.

Figure 3 Schematic diagram of the posterior approach to Calot’s triangle. A posterior window is developed to enable a posterior-to-anterior dissection sequence and stepwise anatomic confirmation of the cystic duct and cystic artery. CA: Cystic artery; CD: Cystic duct; CHD: Common hepatic duct; CBD: Common bile duct.
