Abstract:Objective:To evaluate the value of clinical application of the technique of choledochoscopic balloon dilatation of Oddi sphincter.
Methods :The clinical data of 67cases who underwent cholecloscopic ballon dilatation of Oddi sphinctor between Jul 2005 and Apr 2007 was analysed, and compared with those patients who had endoscopic sphincterotomy(EST) during the same period.
Results:There was no difference between balloon dilatation group and EST group in rate of short-term complications and therapentic results (P<0.05), but the rate of reflux biliary tract infection and retained stones was lower in the balloon dilatation group compared to that of EST group(P<0.05).
Conclusions:Choledoscopic dilatation of Oddi sphincter is a safe, feasible and more effective way to treat patients with gallbladder calculi complicated with bile duct calculi, and this method is worthy of widespread use.
