Abstract

BACKGROUND:

laparoscopic appendectomy(LA) has proved to be a safe alternative to open appendectomy(OA) in uncomplicated appendicitis; however, the feasibility of LA for complicated appendicitis(CA) has not been conclusively determined.

OBJECTIVES:

To assess the feasibility and safety of LA for CA through a systematic review and meta-analysis.

METHODS:

A literature search in PubMed, Embase, Cochrane Library, and web of Science was performed for eligible studies published from the inception of the databases to January 2016. All studies comparing LA and OA for CA were reviewed. After literature selection, data extraction and quality assessment were performed by two reviewers independently, and meta-analysis was conducted using Revman software, vision 5.2.

RESULTS:

Two randomized controlled trials (RCTs) and 14 retrospective cohort studies(RCSs) were finally identified. Our meta-analysis showed that LA for CA could reduce the rate of surgical site infections (SSIs) (OR = 0.28; 95% CI: 0.25 to0.31, P < 0.00001), but LA did not increase the rate of postoperative intra-abdominal abscess(IAA) (OR = 0.79; 95% CI: 0.45 to 1.34, P = 0.40). The results showed that the operating time in the LA groups was much longer than that in the OA groups (WMD = 13.78, 95% CI: 8.99 to 18.57, P < 0.00001). However, the length of hospital stays in the LA groups were significantly shorter than those in the OA groups (WMD = -2.47, 95%CI: -3.75 to -1.19, P < 0.0002), and the time until oral intake(TTOI) was much earlier in the LA groups than in the OA groups (WMD = -0.88, 95% CI: -1.20 to -0.55, P < 0.00001). No significant difference was observed in the times of postoperative analgesia between the two groups(P > 0.05).

CONCLUSION:

LA was feasible and safe for complicated appendicitis, and it not only could shorten the hospital stays and the time until oral intake, but it could also reduce the risk of surgical site infection.
