Brief Summary:
The aim of the study is to evaluate the anorectal function after hemicolectomy if we preserve or not the Inferior Mesenteric Artery (IMA). This study wants to demonstrate that IMA preservation could improve patient's quality of life reducing incontinence and/or constipation rate.

Arm Intervention/treatment
Experimental: Inferior Mesenteric Artery Preservation
Performing left hemicolectomy the IMA was preserved ligating close to the colonic wall the sigmoids arteries.
 Procedure: Inferior Mesenteric Artery Preservation
Performing left hemicolectomy the IMA was preserved ligating close to the colonic wall the sigmoids arteries.
Other Name: IMA-P
Active Comparator: Inferior Mesenteric Artery Ligation
Performing left hemicolectomy the IMA is ligated and sectioned after the origin of left colic artery
 Procedure: Inferior Mesenteric Artery Ligation
Performing left hemicolectomy the IMA is ligated and sectioned after the origin of left colic artery
Other Name: IMA-L


Outcome Measures
Go to

Primary Outcome Measures :
  1. Change from preoperative time in anorectal function [ Time Frame: 6 and 12 months ]
    We evaluate the presence of modification in anorectal function respect to the preoperative time. This is assessed with specific questionnnaires and anorectal manometry


Secondary Outcome Measures :
  1. Constipation [ Time Frame: 6 and 12 months ]
    We evaluate with a questionnaire (Constipation scoring system) the presence of postoperative constipation

  2. Incontinence [ Time Frame: 6 and 12 months ]
    We evaluate with a questionnaire (Continence scale), anorectal manometry and eventually with endoanal ultrasonography the precence of incontinence

  3. Quality of life [ Time Frame: 6 and 12 months ]
    We evaluate with SF-36 questionnaire the postoperative quality of life

  4. Postoperative complication [ Time Frame: 1 month ]
    We evaluate the presence of postoperative complication such as anastomotic leakage, anastomotic stricture, pneumonia etc.
