ABSTRACT
Objective To study the clinical application of laparoscopic cholecystectomy (LC) combined with intraoperative endoscopic sphincterotomy (IOEST) with the antegrade guidewire technique in the treatment of cholecystocholedocholithiasis.Methods This is a prospective controlled study comparing LC combined with preoperative endoscopic sphincterotomy (POEST) versus LC combined with IOEST in the treatment of cholecystocholedocholithiasis.Patients who were diagnosed to have cholecystocholedocholithiasis from June 2012 to February 2013 in our hospital were divided into the POEST group and the IOEST group.There were 50 patients in each group.The operation time,successful stone-extraction rate,residual stones rate,complication rate,postoperative stay and hospitalization cost between the groups were compared.Results The sex,age,stone size,number of stones and diameter of the common bile duct showed no significant difference between the two groups (P ＞ 0.05).There were no differences between the two groups in surgical time of EST,surgical time of LC combined with EST,successful stone-extraction rate and hospitalization cost (P ＞ 0.05).There were significant differences between the two groups in the residual stones rate,postoperative hyperamylasemia rate,postoperative acute pancreatitis rate and postoperative stay (P ＜0.05).LC combined with IOEST using the antegrade insertion of guidewire technique significantly reduced the residual stones rate (0 vs 8％),postoperative hyperamylasemia rate (4％ vs 18％),postoperative acute pancreatitis rate (0 vs 8％) and postoperative stay.Conclusions LC combined with IOEST using the antegrade guidewire technique could be performed safely when compared with the traditional sequential technique,LC combined with IOEST using the antegrade guidewire technique significantly reduced the postoperative acute pancreatitis rate and the residual stones rate.LC combined with IOEST using the antegrade guidewire technique should be the recommended technique to treat patients with cholecystocholedocholithiasis.
ABSTRACT
Objective To study the value of sequential duodenoscopic-laparoscopic treatment in patients with cholelithiasis. Methods Clinical data of 2 248 cases of cholelithiasis treated with sequential duodenoscopic-laparoscopic plan from January 2000 to December 2004 were retrospectively reviewed. Results Duodenoscopy indicated the confirmative diagnosis of gallbladder stones in 1 817 cases and gallbladder stones with associated common bile duct stones in 431 cases. Among 2 021 cases diagnosed as having gallbladder stones by B-ultrasonography: endoscopic retrograde cholangiopancreatography (ERCP) was performed in 690 cases, 213 of which were found having associated common bile duct stones; intraoperative cholangiography (IOC) was conducted in 85 cases, 10 of which were found presenting common bile duct stones; residual stones in the common bile duct after laparoscopic cholecystectomy (LC) were noted in 6 cases which were cured by endoscopic sphincterotomy (EST). Among 227 cases diagnosed as having gallbladder stones combined with common bile duct stones by B-ultrasonography, the diagnosis of common bile duct stones were confirmed by ERCP in 202 cases. Out of the 2 248 cases, 1 817 cases underwent the LC, 395 cases received EST and LC, and 36 cases were given the laparoscopic bile duct exploration (LBDE) (the bile duct was closed by primary suture in 26 cases and a T-tube was left in the bile duct in 10 cases). The 6 cases of residual stones in the bile duct were cured with EST postoperatively. A total of 28 cases required a conversion to open surgery (1.2%), and complications occurred in 52 cases (2.3%). Conclusions Sequential duodenoscopic- laparoscopic treatment for cholelithiasis offers a low residual stone rate and a high success rate.
