BACKGROUND: Short-stay laparoscopic appendectomy for acute appendicitis (AA) has not yet been validated. This study was designed to prospectively evaluate the hospital length of stay (LOS) after laparoscopic appendectomy for AA and to determine predictive factors for successful short-stay surgery (LOS <24 h). METHODS: Between January and December 2010, all consecutive adults admitted for AA were prospectively treated with LOS <24 h as a patient management goal. The proportion of patients with LOS <24 h was analyzed for the intention-to-treat (ITT) population and for the population eligible for short-stay surgery. Predictive factors for LOS <24 h were analyzed. RESULTS: Of the 123 patients included in this study, 71.5 % (88/123) were eligible for short-stay surgery. The proportion of LOS <24 h cases was 52 % (64/123) in the ITT population and 72.7 % (64/88) in the eligible population. LOS <12 h was achieved in 17.8 % (22/123) in the ITT patients and 25 % (22/88) of the eligible patients. The main cause of unexpected readmission was postoperative pain (n = 10, 8.1 %). Age <23 years and a serum C-reactive protein level <18 mg/l had a positive predictive value of 100 % for LOS <24 h. Of the eligible patients, 27.2 % (24/88) were subject to unplanned overnight admissions and postsurgery readmissions. CONCLUSIONS: LOS <24 h was feasible for 52 % of patients admitted for AA and for 72.7 % of the patients eligible for short-term surgery. Low age and a low preoperative serum CRP level are predictive factors for the feasibility of short-stay laparoscopic appendectomy for AA.
