Purpose: The purpose of this study was to determine the frequency and causes of bile duct dilatation following subtotal gastrectomy.
Materials and Methods: We retrospectively reviewed consecutive 55 patient’s pre-operative and post-operative abdominal computed tomography. Patients with early gastric carcinomas were 19 (Billroth I=10, II=9), and patients with advanced gastric carcinomas were 36 (Billroth I=16, II=20). We also reviewed medical records of all patients to get the level of total bilirubin and alkaline phosphatase at approximate period of CT examination.
Results: Intrahepatic bile duct dilatation was seen in 25 patients (45%). The frequency of intrahepatic bile duct dilatation was higher in patients who had Billroth II operations (52%) than Billroth I operation (38%). But the difference was not statistically significant (p0.05). Intrahepatic bile duct dilatation was seen more frequently in patients with advanced gastric carcinomas (56%) than early gastric carcinomas (26%, p0.05). Regardless of anastomotic methods and types of gastric cancer, mean diameter of extrahepatic bile duct dilatation has increased after gastrectomy in all groups (p0.05).
Conclusion: Bile duct dilatation is frequently seen after subtotal gastrectomy, especially when the patient had advanced gastric carcinoma or received Billroth II anastomosis.
