[Obstructing colon cancer--what's the surgical strategy?].

Introduction: The aim of the study was to define the therapeutic approach used for obstructing colon cancer.

Patients And Methods: In the period 1990-2002 in the Emergency Surgery Department of the University of Naples Federico II, 81 patients underwent colon surgery for obstructing colon cancer (25 M, 57 F, age range: 55-88 years, mean: 72). Were performed subtotal colectomies, left or right hemicolectomies, sigmoid colectomies, anterior resections, temporary or permanent enterostomies. The authors put morbidity and mortality in touch with the type of surgical operation and with results of the literature.

Results: Mortality was 32%: 2.4% as a result of an anastomotic dehiscence; 4.9% for cardiovascular pathologies; 1.2% for sepsis; 23.4% for metastasis. Morbidity for anastomotic leakage was 4.9%: 2.4% after left emicolectomy and colo-colonic anastomosis; 1.2% after right emicolectomy and ileo-colonic anastomosis; 1.2% after defunctioning colostomy and left emicolectomy after 20 days.

Conclusions: This experience suggests that a subtotal colectomy with primary anastomosis (one stage) can be performed more safely, by an experienced, skilled surgeon, in patients in good clinical conditions with acute obstruction of the colon. Healing remains a process depending more on the patient than on any aspect of the surgical technique. A defunctioning colostomy may be idealfor surgeons with little experience in colorectal surgery and in high risk patients with a very poor prognosis (unresectable lesions).
