Sixty nine patients over 75 years old who had a colectomy were retrospectively studied. The carcinoma of the colon represented the main indication for 42 cases (60.9%) and 22 patients (31.9%) were immediately operated. The influence of parameters such as age, sex, visceral defects, emergency, performance of a colostomy or associated intervention, type of colic pathology, was statistically studied. The age (p less than 0.05), emergency (p less than 0.03) and the number of defects greater than or equal to 3 (p less than 0.04) contribute to mortality. The number of defects greater than or equal to 3 (p less than 0.006) contributes to general morbidity. Only complications connected with the operation by itself significantly prolong the duration of hospitalization (p less than 0.02). The authors draw the conclusion that the age by itself is not a contra-indication for operation except in case of associated polyvisceral failure. In addition, it is required to carry out an early detection of colic lesions in elderly subjects in order to contemplate surgery before complications whose prognosis is fearsome (54.5% of death in emergency operation).
