Abstract
OBJECTIVES: Anastomotic leakage (AL) after anterior resection always leads to longer hospital stays, decreased quality of life and even increased mortality. Despite extensive research, no consensus on the world well-concerned surgical-related risk factors exists. We therefore conducted a meta-analysis of the available published literature to identify the effects of surgical-related risk factors for AL after anterior resection for rectal cancer, hoping to provide more information and improved guidance for clinical workers managing patients with rectal cancer who are at a high risk for AL. METHODS: In this study, the relevant articles were systematically searched from EMBASE, MEDLINE, PubMed, WangFang (Database of Chinese Ministry of Science & Technology), Chinese National Knowledge Infrastructure Database and China Biological Medicine Database. The pooled odds ratio (OR) with 95% confidence interval (95% CI) were calculated. Meta-analysis was performed using of RevMan 5.3 software. RESULTS: A total of 26 studies met the inclusion criteria and comprised 34238 cases. Analysis of these 26 studies showed that no defunctioning stoma was highly correlated with AL (pooled OR = 1.28, 95%CI: 1.05-1.57, P = 0.01, random effect), and intraoperative blood transfusion was significantly associated with AL (pooled OR = 1.64, 95%CI: 1.34-2.02, P = 0.02, random effect). However, the AL was not associated with type of anastomosis, type of surgery, technique of anastomosis, level of inferior mesenteric artery ligation, operation time and splenic flexure mobilization. CONCLUSIONS: Depend on this meta-analysis, no defunctioning stoma and intraoperative blood transfusion are the major surgical-related risk factors for AL after resection for rectal cancer. Because of the inherent limitations of the research, future prospective randomized controlled trials will need to confirm this conclusion.
