| Popis: | Purpose: To provide immediate information on the anatomic position of the cystic duct for surgical candidates with biliary disease, we evaluate the insertion site of the cystic duct into the common bile duct by using computed tomography (CT). Materials and Methods: Axial CT images of 126 patients with biliary disease were reviewed by measuring the insertion angle between the dilated cystic duct and common bile duct. The insertion site of the cystic duct was located posterior to the horizontal line crossing the center of the common bile duct, i.e., the posterior insertion, in 115 patients (91.3%). Considering the negligible frequency of the anterior insertion (8.7%), we finally analyzed the patients with posterior insertion by subdividing the insertion angle at an interval of 20. Results: In total, 11 and 115 patients show the anterior and posterior insertion, respectively. The patient distribution with the posterior insertion was 1 (0-20), 7 (20-40), 26 (40-60), 43 (60-80), 15 (80-100), 7 (100-120), 8 (120-140), 5 (140-160), and 3 (160-180). The mean insertion angle was 77.4. Conclusion: We designed the method to readily evaluate the insertion site of the cystic duct at CT. Accordingly, the cystic duct sites were predominantly located posterior to the common bile duct, and most of them ranged from 40to 100. |
