Abstract    Objective    To evaluate the clinical value of choledochoscopy for the treatment of pancreatolithiasis. Methods    From January 2004 to September 2009, choledochoscopy was used in 9 patients with pancreatolithiasis during a dissection of the pancreatic duct combined with pancreato-jejunum Roux-en-Y anastomosis (choledochoscopy group ) in Shengjing Hospital of China Medical University. The data of choledochoscopy group were compared with the data of 12 patients with pancreatolithiasis treated by routine dissection of the pancreatic duct combined with pancreato-jejunum Roux-en-Y anastomosis from January 2003 to September 2009 (Routine group). Results    The intraoperative blood loss and the postoperative rate of residual stones in the choledo-choscopy group were significantly less than those in the routine group ［(233.3±55.9)mL vs. (583.0±135.4)mL, ( t = 5.448, P =0.031); and (0 vs. 41.7% , P = 0. 045 )］. The postoperative rate of pain relief in the choledochoscopy group was higher than that in the routine group (88.9% vs. 50.0%). However the difference was not significant (P=0.159). Conclusion    Choledochoscopy is effective for the treatment of pancreatolithiasis. The procedure can increase the rate of stone removal, decrease the intraoperative blood loss and elevate the postoperative rate of pain relief.
