Risk factors for cholecystectomy: analysis of 935 patients.

We evaluated 935 patients for risk factors of cholecystectomy. Factors assessed included reason for cholecystectomy, preoperative laboratory values, sex, age, weight, presence of associated disease, and pathologic findings. Evaluation revealed an overall significant complication rate of 10.50% and a mortality of 1.07%. Risk factors were age over 60 years, hypertension, atherosclerotic cardiovascular disease with prior heart failure, and acute cholecystitis. Incidental cholecystectomy was associated with an increased risk due to concomitant associated disease. Patients with obesity and uncomplicated diabetes had the same risk as the general population.
