Abstract
Background
Defecatory disorders are very common complications after left hemicolectomy and anterior rectal resection. These disorders seem related primarily to colonic denervation after the resection. To evaluate the real benefits of inferior mesenteric artery (IMA) preservation via laparoscopic left hemicolectomy performed for diverticular disease in terms of reduced colonic denervation and improved postoperative intestinal functions, a randomized, single-blinded (patients) controlled clinical trial was conducted.
Methods
From January 2004 to January 2010, patients with symptomatic diverticular disease and a surgical indication were enrolled in the study and randomly assigned to two treatment groups. The first group underwent laparoscopic left hemicolectomy, which preserved the IMA by sectioning the sigmoid arteries one by one near the colonic wall, In the second group, the IMA was sectioned immediately below the origin of left colic artery. Defecation disorders were assessed by anorectal manometry and by three questionnaires to evaluate constipation, incontinence, and quality of life 6 months after the intervention.
Results
A total of 107 patients were included in the study. The 54 patients with preserved IMA showed a statistically lower incidence of defecation disorders such as fragmented evacuations, alternating bowel function, constipation, and minor incontinence, as well as less lifestyle alteration than the 53 patients with the IMA sectioned just below the left colic artery.
Conclusions
This study confirmed that preservation of the IMA should be recommended to reduce the incidence of defecatory disorders after left hemicolectomy for benign disease.
