Abstract
The objectives of this study are to define the distinguishing features between elective and emergency colonic surgery. The records of adult patients who underwent elective and emergent colonic resection over a 4-year period were retrospectively reviewed. Univariate analysis was performed to compare outcomes for elective and emergency procedures and multiple logistic regression analysis was performed to identify the significant predictors of outcome. Three hundred and thirty-eight elective and 147 emergency colonic resections were performed. Diverticular disease was most common in the emergency group (43.5% vs 14.2%, P = 0.001) whereas malignancy predominated in the elective group (56.2% vs 5.4%, P = 0.001). The emergency group accounted for 54.7 per cent and 79.3 per cent of the total morbidity and mortality. Emergency colonic surgery has distinctive features and significance. Emergency surgery for colonic obstruction and total/subtotal resection are associated with higher morbidity and mortality. Diverticular disease compares favorably to other pathologies in postoperative outcome.
