[Comparison of open versus laparoscopic surgeries for adrenal tumor: a meta-analysis].

OBJECTIVE: To systematically review the effectiveness and safety of open and laparoscopic surgeries for treatment of adrenal tumors. METHODS: The online databases including CNKI, PUBMED, SinoMed, EBSCO, Springerlink, WanFang Data, and VIP were searched for clinical trials published from 1999 to 2016. A meta-analysis was performed using RevMan 5.2 software. RESULTS: A total of 2340 patients in 25 trials were included. The results of meta-analysis showed that laparoscopic surgery was better than open surgery in terms of intestinal function recovery time (OR=-0.96, 95%CI [-1.22, -0.70] P<0.000 01), hospitalization time (OR=-3.48, 95%CI [-4.13, -2.78], P<0.000 01), complications (OR=0.22, 95%CI [0.14, 0.35], P<0.0001), and volume of blood loss (OR=-104.77, 95%CI [-138.95, -70.60], P<0.000 01). There was no significant difference in the surgery cost between open and laparoscopic surgeries. CONCLUSION: Laparoscopic surgery is superior to open surgery for treatment of adrenal tumors for shorter intestinal function recovery time, surgery duration, and hospitalization time and less complications and blood loss.
