Abstract:
Objective To evaluate the possibility,efficacy and safety of endoscopic balloon dilation(EBD)for the treatment of common bile duct stones.Methods EBD of the sphincter of Oddi and removal of the stones by balloon,basket net and mechanical lithotripsy were performed in 47 patients with common bile duct stones.In order to prevent the possible complicated pancreatitis,Sandostatin,endoscopic nasobiliary drainage(ENBD)and small sphincterotomy were used according to the patients conditions.Results The success rate of EBD for the treatment of common bile duct stones was 91 5%(43/47)in our group.During one EBD session the common bile duct was cleared in 41(87 2%)of 47 cases.Incomplete duct clearance was achieved in 2(4 3 %)cases,both of whom underwent repeated EBD with successful duct clearance without undergoing endoscopic sphincterotomy(EST).Mechanical lithotripsy was required in 27(57 4%)of the 47 cases for stones greater than 1 0cm in diameter.Failure to clear the common bile duct with EBD in 4 cases(8 5%)was primarily related to large stones size (≥2 0cm),in whom EST was required to clear the duct.No perforation or hemorrhage was observed.Temporal hyperamylasemia was observed in 11 patients,only 1 of whom was accompanied by abdominal pain,which was rapidly relieved through conservative treatment.Conclusion EBD for the treatment of common bile duct stones is possible,effective and safe.
