Preserving Inferior Mesenteric Artery During Elective Laparoscopic Sigmoidectomy for Diverticulitis.

Abstract

Context: During a Laparoscopic Sigmoid Resection (LSR) for patients with diverticulitis, the inferior mesentericartery may or may not be preserved depending on the surgical technique. We aimed to evaluate results afterLSR with Inferior Mesenteric Artery Preservation (IMAP) and Superior Rectal Artery Preservation (SRAP)in terms of anastomotic leakages and denervation of the hypogastric nerves with consequent genitourinary anddefecation alterations.Evidence Acquisition: A retrospective PubMed research of manuscripts published from January 2000 to January2020 was conducted, enrolling studies about patients with symptomatic diverticular disease who underwent surgery.Results: A total of 1685 patients with IMAP and SRAP were included in the study.Conclusion: This retrospective review showed that patients with IMAP-SRAP demonstrated an equal or lowerleakage rate with reduced incidence of stoma, lower incidence of defecation disorders, and similar or improvedquality of life compared with laparoscopic left colectomy with no IMAP.
