Risk of anastomotic bleeding after left colectomy with preservation of inferior mesenteric artery for diverticular disease: preliminary results

BACKGROUND: The inferior mesenteric artery (IMA) preservation in elective laparoscopic left colectomy for diverticular disease may reduce the risk of anastomotic leakage. However, an increased risk of bleeding is assumed. The purpose of this study is to investigate the risk of colorectal anastomosis bleeding, when IMA is resected or preserved during left colectomy.METHODS: A retrospective review of a prospectively collected database was...
