Surgical outcomes and prognostic factors associated with emergency left colonic surgery

Mortality from emergency left-sided colorectal surgery can be substantial due to acuteness of the presentation and the urgent need to operate in the setting of a limited preparation in a morbid patient.

Determine the 30-day postoperative outcomes and identify risk factors for complications and mortality following emergency colorectal operations.

Retrospective SETTINGS: Three tertiary hospitals in three countries.

Factors that were studied included age, sex, ASA score, type and extent of the operation, and presence/absence of malignancy. Unadjusted 30-day patient outcomes examined were complications and mortality. Differences in proportions were assessed using the Pearson chi-square test while logistic regression analyses were carried out to evaluate the correlation between risk factors and outcomes.

30-day postoperative morbidity and mortality SAMPLE SIZE: 104 patients.

Among 104 patients, 70 (67.3%) were men, and 34 (32.7%) were women. The mean (SD) age was 57.2 (17.1) years. The most common indication for emergency colonic surgery was malignant obstruction in 33 (31.7%) patients. The postoperative complication rate was 24% (25/104), and the mortality rate was 12.5% (13/104) within 30 days of the operation. The ASA status (P=.02), presence of malignancy (P=.02), and the presence of complications (P=.004) were significantly related to mortality in the multivariable logistic regression analysis.

The 30-day mortality of emergency colorectal operations is greatly influenced by the presence of malignancy in the colon and physiological status at the time of the procedure.

The retrospective design and small sample size.

None.
