Comparison Study between ERCP and PTBD for Recurrent Choledocholithiasis in Patients Following Gastrectomy

The recurrence rate of choledocholithiasis in the general population has been reported to exceed 10%. incidence cholelithiasis was be higher patients following gastrectomy than that population. However, there is no study for recurrent gastrectomy. This aimed evaluate and identify risk factors A retrospective analysis performed on with history who underwent removal Kyungpook National University Hospital between January 2011 December 2019. Choledocholithiases were treated by endoscopic retrograde cholangiopancreatography (ERCP) (n = 41) or percutaneous transhepatic biliary drainage (PTBD) 90). type classified as subtotal Billroth I (18.3%), II (45.0%), total Roux-en-Y (36.6%). During a median follow-up period 31.5 (range, 6–105) months, noted 19 131 (14.5%). In subgroup analysis, ERCP group (24.4%) had PTBD (10.0%). Stone modality (ERCP), use balloon sphincteroplasty, presence periampullary diverticulum significant choledocholithiasis. multivariate (hazard ratio (HR), 3.597; 95% confidence interval (CI): 1.264–10.204) CBD stricture (HR, 3.823; CI: 1.118–13.080) sphincteroplasty 4.830; 1.669–13.889) stone removal. stones similar ERCP, stricture, are potential When we consider disadvantages, procedure active recommended decrease stones.
