This is a prospective randomized study aimed to verifying the short and long-term results of inferior mesenteric artery preservation following colorectal resection for diverticular disease
This study wants to demonstrate that the preservation of the inferior mesenteric artery allow to improve postoperative defecatory function and improve patient\'s quality of life.

Performing left hemicolectomy, sigmoidectomy or rectal resection the IMA was preserved ligating the sigmoids arteries close to the colonic wall
Performing left emicolectomy, sigmoidectomy or rectal resection the IMA is sectioned after the origin of left colic artery.
Defecatory disorders
the presence of defecatory disorders was evaluated (Costipation, Evacuation frequency,evacuation urgency, fragmented evacuation,flatus incontinence, liquid incontinence)

Constipation
The incidence and severity of postoperative constipation was evaluated with Cleveland Clinic Constipation Score ( score range from 0 to 30, the higher score defines worse constipation status)
