Sigmoid resection for diverticular disease - to ligate or to preserve the inferior mesenteric artery? Results of a systematic review and meta-analysis.

This meta-analysis failed to demonstrate a statistically significant difference in the anastomotic leakage rate when comparing IMA preservation with IMA ligation. Thus, to date there is insufficient evidence to recommend the IMA-preserving technique as mandatory in resection for left-sided colonic diverticular disease.
