Objective To assess the benefits and harms of routine primary suture (LBEPS) versus T-tube drainage (LCHTD) following laparoscopic common bile duct stone exploration. Methods The randomized controlled trials (RCTs) or quasi-RCTs were electronically searched from the Cochrane Controlled Trials Register (The Cochrane Library, Issue 2, 2010), PubMed (1978 to 2010), EMbase (1966 to 2010), CBMdisc (1978 to 2010), and CNKI (1979 to 2010); and the relevant published and unpublished data and their references were also searched by hand. The data were extracted and the quality was evaluated by two reviewers independently, and the RevMan 5.0 software was used for data analysis. Results Four studies including 3 RCTs and 1 quasi-RCT involving 274 patients were included. The meta-analysis showed that compared with LCHTD, LBEPS was better in shortening operation time (WMD= –17.11, 95%CI –25.86 to –8.36), abdominal drainage time (WMD= –0.74, 95%CI –1.39 to –0.10) and post-operative hospitalization time (WMD= –3.30, 95%CI –3.67 to –2.92), in lowering hospital expenses (WMD= –2 998.75, 95%CI –4 396.24 to –1 601.26) and in reducing the complications due to T-tube such as tube detaching, bile leakage after tube drawing, and choleperitonitis (RR=0.56, 95%CI 0.29 to 1.09). Conclusion LBEPS is superior to LCHTD in total effectiveness for common bile duct stone with the precondition of strictly abiding by operation indication. Due to the low quality of the included studies which decreases the reliability of this conclusion, more reasonably-designed and strictly-performed multi-centered RCTs with large scale and longer follow up time are required to further assess and verify the efficacy and safety of this treatment.
Objective To evaluate the safety and efficacy of primary closure (PC) and T-tube drainage (TD) after laparoscopic common bile duct exploration (LCBDE). Methods The randomized controlled trials of PC and TD after LCBDE were retrieved from the Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until April 2015. All calculations and statistical tests were performed using ReviewerManager 5.2 software. Results Both of the two groups had no postoperative deaths within 30 days. The operative time and hospital stay of PC gourp were shorter than TD group statistically〔OR=–24.76, 95CI (–29.21, –20.31),P<0.000 01〕and〔OR=–2.68, 95%CI (–3.69, –1.67),P<0.000 01〕. The reoperative rate of PC group was lower than that of TD group, and the difference was statistically significant〔OR=0.20, 95%CI (0.05, 0.81),P=0.02〕. There was no significant difference between the two groups in the occurrence of postoperative severe complications〔OR=0.54, 95%CI (0.26, 1.12),P=0.10〕. Conclusions Compared with the TD group, the operative time and hospitalization time are shorer in PC group, and complication rate is similar, but the cost of treatment of the TD group is higher than PC group, so after LCBDE a primary closure of common bile duct is safe and effective method.
