Introduction: Success in nonoperative management is only based on the clinical symptoms of patients with acute appendicitis. However, imaging studies can provide further insight into the status of the appendix to monitor treatment response if immediate appendectomy is not undertaken. This study investigates sonographic resolution following nonoperative management and assesses the feasibility of incorporating ultrasound into patient care. Materials and Methods: Adult patients with acute appendicitis who had been successfully treated with nonoperative management were enrolled and received repeat sonographic examinations using 3-day intervals until sonographic resolution. The relationship between the time to achieve sonographic resolution and clinical parameters was identified using negative binomial regression models. Results: From January 2003 to December 2009, 128 patients were successfully treated with nonoperative management. Eighty patients completed sonographic examinations until achieving resolution. Sonographic resolution was achieved on 17 ± 12 days (range, 3-69 days). Ninety-five percent of the patients achieved sonographic resolution within 41 days. The appendicolith was positively related to the time to achieve sonographic resolution (rate ratios, 1. 63; 95 % confidence intervals, 1. 06-2. 51). Conclusions: Ultrasound can be used to evaluate the condition of the appendix to monitor treatment response following nonoperative management on the sixth week.
