Antegrade spyglass and lithoripsy as treatment modality for retained intrahepatic duct stone after biliary reconstruction

Abstract

The mean observation period was longer for the LCJ group than for the OCJ group (31.6 vs. 25.3 months, p = 0.03). The incidence of postoperative cholangitis tended to be higher (16.9% vs. 8.2%, p = 0.061) and the incidence of intrahepatic stone was significantly higher in the LCJ group (8.4% vs. 1.9%, p = 0.035). The proportion of patients who required invasive intervention for anastomotic stenosis, such as endoscopic or percutaneous stenting or surgical reanastomosis, was significantly higher in the LCJ group (11.7% vs. 1.9%, p = 0.005). Conclusions: Although LCJ using continuous suture had been standardized within the study period, it is more likely to cause anastomotic stenosis than OCJ using interrupted suture.
