Does a 48-hour rule predict outcomes in patients with acute sigmoid diverticulitis?
INTRODUCTION: Sigmoid diverticulitis is an infection that resolves with conservative management in 70-85% of patients. Some patients require prolonged hospitalization or surgery during their admission. It has been taught that one should expect clinical improvement within 48 h. In this study, we examined whether basic clinical parameters (the maximum temperature and leukocyte count) of patients would predict improvement and discharge as expected, or prolonged hospitalization. MATERIALS AND METHODS: Data was acquired from 198 patients admitted with acute sigmoid diverticulitis as confirmed by computed tomography (CT) scanning and physical exam. One hundred sixty-five patients recovered without surgery with an average hospital stay of 4 days: 120 were discharged within 4 days, whereas 45 patients required longer stays. Nineteen patients underwent surgery early during their admission (within 48 h). Fourteen patients did not improve over time and required surgery later during their hospital
