Abstract 70P
Background
The safety and efficacy of intraoperative endoscopic nasobiliary drainage over primary closure of the common bile duct plus laparoscopic cholecystectomy (ENBD+ LC+ LCBD) for cholecystolithiasis combined with common bile duct stones (CBD stones) are uncertain.
Methods
The meta-analysis search was performed using PUBMED, OVID, EMBASE, and Cochrane database. All studies comparing ENBD+ LC+ LCBD and ECRP/EST+ LC from 1990 to 2018 were included. Pooled effect was calculated using the fixed and random effects models when necessary.
Results
A total of 5 trails included 700 patients with two different treatments (ENBD+ LC+ LCBD and ECRP/EST+ LC) were identified. The ENBD+ LC+ LCBD group had less total complications or adverse events (RR = 0.268, 95% CI:0.138–0.520, I2=0.0%, P < 0.001). And subgroup analysis of total complications exposed that although ENBD+ LC+ LCBD group developed more of biliary leak, there was no significance (RR = 3.890, 95% CI:0.88–17.25, I2=0.0%, P = 0.074). Meanwhile, there were lower rates of retained stones (RR = 0.272, 95% CI:0.09–0.85, I2=0.0%, P = 0.026), postoperative bleeding (RR = 0.129, 95% CI:0.02–0.75, I2=0.0%, P = 0.022) and pancreatitis (RR = 0.127, 95% CI:(0.04–0.43, I2=0.0%, P = 0.001) in ENBD+ LC+ LCBD group. Although operative time (WMD=32.465, 95% CI:0.468–64.61, I2=98.6%, P = 0.047) showed significant difference, sensitivity analysis didn’t confirm the robustness of the results. Futhermore, it seemed that ENBD+ LC+ LCBD group had a shorter length of postoperative hospital stay (WMD=-1.880, 95% CI:-3.063–-0.696, I2=94.4%, P = 0.002) and less expenditure of hospitalization (WMD=-430.439, 95% CI:-704.620–-156.258, I2=92.3%, P = 0.002).
Conclusions
It is safe and efficient by intraoperative endoscopic nasobiliary drainage over primary closure of the common bile duct for patients with cholecystolithiasis combined with CBD stones.
