BACKGROUND: Preservation of the inferior mesenteric artery (IMA) and consequential blood flow to the rectum would reduce the risk of leakage of a colorectal anastomosis. METHODS:One hundred and sixty-three patients undergoing left colectomy for complicated diverticular disease of the colon were randomly placed into two groups: A, n = 86; and B, n = 77. In group A, the integrity of the IMA was preserved by artery skeletization (IMAS); in group B, the IMA was divided at its origin. Variables recorded included duration of the surgical procedure, need for blood transfusion, length of hospital stay, operative mortality and morbidity, staple-ring disruption, and radiologic and clinical leakage. Anastomotic stenosis and recurrence of diverticular disease were noted. RESULTS:Surgical time was superior in the IMAS group. Radiologic and clinical leakages were significantly higher in group B (P = 0.02, P = 0.03, respectively). In group A a significant lower number of staple-ring disruptions was observed, evolving into clinical dehiscence. CONCLUSION: Preserving the natural blood supply to the rectum and the ensuing use of a healthy well-nourished rectal stump are suggested as the main aspects of IMAS in preventing and healing leakage of colorectal anastomosis.
