Laparoendoscopic single-site versus traditional laparoscopic surgery in patients with cholecystectomy: a meta-analysis.
OBJECTIVE
To evaluate the primary outcomes of traditional laparoscopic cholecystectomy (TLC) compared with laparoendoscopic single-site cholecystectomy (LESSC).


METHODS
Randomized controlled trials (RCTs) comparing TLC with LESSC were included by a systematic literature research. The inclusion and extraction of the data were completed by two authors independently. Meta-analysis was performed using Review Manager version 5.1.4 software. The clinical outcomes were evaluated by odds ratio (OR) and standard mean difference (SMD) according to the different types of data. Sensitivity and heterogeneity analyses were used to account for rationality of pooling data and sources of heterogeneity.


RESULTS
Seven RCTs involving 611 patients met the predefined inclusion criteria. The cosmetic score of the LESSC group was significantly higher at 1 week (SMD = 0.48; 95% confidence intervals [CI] 0.24, 0.73; P = .0001), 2 weeks (SMD = 0.87; 95% CI 0.61, 1.13; P < .00001), and 1 month (SMD = 0.88; 95% CI 0.62, 1.44; P<.00001) postoperatively. However, LESSC showed a lesser physical quality of life (PQOL) score at 3 days (SMD = -0.28; 95% CI -0.52, -0.44; P = .02), 1 week (SMD = -0.31; 95% CI -0.55, 0.06; P = .01), and 2 weeks (SMD = -0.30; 95% CI -0.55, -0.05; P = .02) postoperatively. There was no significant difference between the two groups in operating time, perioperative complication, intraoperative blood loss, postoperative hospital stay, Visual Analog Scale pain score, and PQOL on 1 day, 5 days, and 1 month postoperatively.


CONCLUSIONS
LESSC is associated with a higher cosmetic score and a lesser short-term PQOL score compared with TLC.
