AIM: To determine whether the outcomes of laparoscopic fenestration (LF) were superior to open fenestration (OF) for congenital liver cysts. METHODS: Comparative studies published between January 1991 and May 2010 on Medline (Ovid), Emsco, PubMed, Science Direct; Cochrane Reviews; CNKI; Chinese Biomedical Database, VIP and other electronic databases were searched. Randomized controlled trials (RCTs) and retrospective case-control studies on the management of congenital hepatic cysts were collected according to the pre-determined eligibility criteria to establish a literature database. Retrieval was ended in May 2010. Meta-analysis was performed using RevMan 5.0 software (Cochrane library). RESULTS: Nine retrospective case-control studies involving 657 patients, comparing LF with OF were included for the final pooled analysis. The meta-analysis results showed less operative time [mean difference (MD): -28.76, 95% CI: -31.03 to 26.49, P < 0.00001]; shorter hospital stay (MD: -3.35, 95% CI: -4.46 to -2.24, P < 0.00001); less intraoperative blood loss (MD: -40.18, 95% CI: -52.54 to -27.82, P < 0.00001); earlier return to regular diet (MD: -29.19, 95% CI: -30.65 to -27.72, P < 0.00001) and activities after operation (MD: -21.85, 95% CI: -31.18 to -12.51, P < 0.0001) in LF group; there was no significant difference between the two groups in postoperative complications (odds ratio: 0.99, 95% CI: 0.41 to 2.38, P = 0.98) and cysts recurrence rates. CONCLUSION: The short-term outcomes of LF for patients with congenital hepatic cysts were superior to open approach, but its long-term outcomes should be verified by further RCTs and extended follow-up.
