OBJECTIVE:
to report clinical and pathological features of patients with colorectal cancer diagnosed during emergency abdominal surgery.
METHODS:
records of 107 patients operated between 2006 and 2010 were reviewed.
RESULTS:
there were 58 women and 49 men with mean age of 59.8 years. The most frequent symptoms were: abdominal pain (97.2%), no bowel movements (81.3%), vomiting (76.6%), and anorexia (40.2%). Patients were divided into five groups: obstructive acute abdomen (n = 68), obstructive acute perforation (n = 21), obstructive acute inflammation (n = 13), abdominal sepsis (n = 3), and severe gastrointestinal bleeding (n = 2). Tumors were located in the rectosigmoid (51.4%), transverse colon (19.6%), ascendent colon (12.1%), descendent colon (11.2%), and 5.6% of the cases presented association of two colon tumors (synchronic tumors). The surgical treatment was: tumor resection with colostomy (85%), tumor resection with primary anastomosis (10.3%), and colostomy without tumor resection (4.7%). Immediate mortality occurred in 33.4% of the patients. Bivariate analysis of sex, tumor location and stage showed no relation to death (p > 0.05%).
CONCLUSIONS:
colorectal cancer may be the cause of colon obstruction or perfuration in patients with nonspecific colonic complaints. Despite the high mortality rate, resection of tumor is feasible in most patients.
