ObjectiveTo summarize our experience of choledochoscopy combined with shockwave lithotomy in the treatment of postoperative retained calculi in biliary tract.
MethodsCholedochoscopy via T-tube fistula and calculus-removing baskets combined with shockwave lithotomy was applied to treat 1 573 patients with postoperative retained calculi in the biliary tract, and the clinical data were analyzed retrospectively.
ResultsOf 1 573 patients,1 511 were cured(96.1%).The calculus-removal sessions varied from 1 to 9 times (average 3.31 times).Complications during treatment included hemobilia in 3 cases, fever in 17 cases and diarrhea in 22 cases rapy.
ConclusionsOwing to its advantages such as safety, effectiveness，mini-trauma and few complications，the choledochoscopic calculus-removing technique combined with shockwave lithotomy is currently an effective approach for treatment of postoperative retained calculi in the biliary tracts.
