ABSTRACT
Objective:To compare the clinical efficacy of percutaneous transhepatic choledochoscope lithotomy (PTCSL) with laparoscopic choledocholithotomy (LD) in treatment of choledocholithiasis.Methods:Data of 132 patients with choledocholithiasis treated at the First Affiliated Hospital of Guangzhou Medical University from July 2012 to December 2018 were retrospectively analyzed. There were 75 males and 57 females, with an average age of 62.7 years. For 76 patients underwent PTCSL (the PTCSL group) and 56 underwent LD (the LD group). The data of the patients the success rate of lithotomy, stone residual rate, operation time, postoperative complications and stone recurrence, chronic cholangitis, and acute cholangitis 1 month after operation were compared between the two groups.Results:The ratio of upper abdominal operation history and biliary tract infection in the PTCSL group was higher than that in the LD group, and the difference was statistically significant (both P<0.05). In the PTCSL group, the calculi were successfully removed in 64 patients in one treatment session, while residual calculi were removed through subsequent sinus choledochoscopy in 9 patients. In the remaining 3 patients, the residual calculi were removed with LD or laparotomy operations. Postoperative complications occurred in 14 patients (19.2%, 14/73). In the LD group, the calculi were successfully removed in one session in 46 patients while in 8 patients the residual calculi were removed by choledochoscopy (1 patient still had residual calculi after choledochoscopy). The remaining 2 patients underwent open surgery due to anatomical difficulties. Postoperative complications occurred in 11 patients (20.4%, 11/54). There were no significant differences between the two groups in the one-off stone removal rate, postoperative stone residual rate, final stone removal rate and postoperative complication rate (all P>0.05). The operation time of the PTCSL group was (156±60) min, which was significantly shorter than the LD group (203±59) min ( P<0.05). There was no significant difference between the two groups in the incidence of postoperative chronic cholangitis and recurrence rate of calculi (both P>0.05). The incidence of acute cholangitis in the PTSCL group was significantly higher than that in the LD group ( P<0.05). Conclusion:PTCSL was as safe and effective as LD, with fewer complications and faster recovery. It is especially suitable for patients with previous upper abdominal surgery, recurrence of calculi and repeated biliary tract infection.
ABSTRACT
Objective To investigate the curative effect on patients with choledocholithiasis by percutaneous transhepatic rigid choledochoscope lithotomy (PTCSL) vs endoscopic retrograde cholangiopancreatography (ERCP) plus EST.Methods From Jan 2010 to Dec 2015,92 cases of choledocholithiasis were treated by one-stage PTCSL (n =23) vs ERCP (n =69).The curative effects and postoperative complications in two groups were observed and analyzed.Results In PTCSL group,the complete stone clearance at one-time achieved in all 23 cases (100％).While in ERCP group stone clearance was achieved in 72.46％ cases at first attempt and the final clearance rate was 82.60％,leaving 12 cases with residual stones and among those 12 cases 5 cases were converted to surgical operation.The average intra-operative hemorrhage in two groups was (20.6 ± 4.6) ml vs (3.0 ± 0.3) ml,and the average hospital stay after operation was 6.8 d and 7 d respectively.The post-operative complications (30.43％) and stone recurrence (13.04％) were similar in the two groups.Conclusions PTCSL is safe,effective,and more suitable to patients with large stones and those with a history of biliary surgeries.
