Choledochoscopy Combined with Electrohydraulic Lithotripsy for the Treatment of Pancreatolithiasis / 中国微创外科杂志

ABSTRACT

Objective To evaluate the clinical value of choledochoscopy combined with electrohydraulic lithotripsy (EHL) for the treatment of pancreatolithiasis. Methods From October 2002 to July 2006, choledochoscopy combined with EHL was used in 11 patients with pancreatolithiasis during a dissection of the pancreatic duct combined with pancreato-jejunum Roux-en-Y anastomosis (EHL group). The data of these patients were compared with the data of 12 patients with pancreatolithiasis, who were treated by routine dissection of the pancreatic duct combined with pancreato-jejunum Roux-en-Y anastomosis from January 1995 to September 2002 (Routine group). Results The intraoperative blood loss and the postoperative rate of residual stones in the EHL group were significantly less than those in the routine group [(145.5?82.0) ml vs (406.7?384.9) ml, t=-2.201, P= 0.039; and 0% vs 41.7%, P= 0.037]. The postoperative rate of pain relief in the EHL group was higher than that in the routine group (90.9% vs 58.3%), however the difference was not significant (P=0.155). In the EHL group, 6 patients had diarrhea before the operation, 4 of them achieved relief after the surgery (4/6), which was not significantly more than that in the routine group (5/9, P=1.000). Before the operation, 7 patients in the EHL group and 9 in the routine group had diabetic mellitus; in each group, the disease was relieved in 2 patients after the operation (2/7 vs 2/9, P=0.665). Conclusions Choledochoscopy combined with EHL 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.
