title: [Colon and rectum cancer complicated with obstruction: immediate results and long-term follow-up].
abstract: Colorectal cancer is the leading cause of large bowel obstruction in Chile. The aim of this work was to assess the immediate results and long term survival of the surgical treatment of this complication. The clinical features of 113 patients (48 male and 65 female) with a mean age of 65 years, operated in a period of 10 years, were reviewed. The follow up was made by clinic appointments or home visits. The tumor was localized in the right colon in 30 cases, transverse colon in 20, splenic angle in 14, left colon in 39 and rectum in 10. Operative mortality was 34% for tumors of the right colon and 14% form tumors of the left colon. The follow up of the 89 survivors was accomplished in 97% with a mean follow up of 54 months (range 6 months-10 years). The principal prognostic factor was the initial stage of the tumor; survival was 87% for Dukes-Turnbull stage A, 70% for stage B and 32% for stage C1. The maximal survival period for stages D was 28 months. Patients subjected to an initial resective surgical procedure fared better, although not significantly, than colostomized patients. Present tendency is to perform one surgical procedure, avoiding colostomies that worsen patients quality of life and require a second intervention that increases surgical morbidity.
