It means that disease severity such as fever, WBC count either uncomplicated or complicated appendicitis did not affect the timing of surgery. In addition, there was no significant difference in the ratio of accompanied by appendicoliths between two groups. In our study, the presence of appendicoliths

Combretastatin A4 molecular weight did not affect the timing of surgery unlike with results of recent studies [24, 25]. There were no significant differences in time to soft diet and length of postoperative hospital stay between two groups. There were also no significant differences in all parameters regarding hospital costs between two groups. Especially, there was no significant difference in complication rate including surgical site infection. One patient in group A and one patient in group B readmitted due to postoperative intra-abdominal abscess within 30 days. These results were similar with previous other studies [7, 19, 20]. Therefore delayed appendectomy is safe similar with early appendectomy. Moreover, mean WBC count

at postoperative first day of group B was lower than that of group A. These results might be due to sufficient and effective preoperative intravenous (IV) antibiotics injection to cover aerobic and anaerobic colonic flora [26]. In our hospital, when a patient was diagnosed as uncomplicated appendicitis by clinical and radiologic evaluation, IV cephalosporin (first or second generation) was given see more to the patient. If a patient was diagnosed as complicated appendicitis, IV metronidazole was added. As a result, patients in group A received single dose preoperative antibiotics and patients in group B Docetaxel order received those twice or three times. There are several limitations of this study. Firstly, this study was retrospective observational study. As above mentioned, several situations such as lack of resident, tight

operation schedule made prospective study difficult. Secondly, optimal timing of appendectomy could not be elucidated. We expect to solve these limitations through the large prospective randomized trial in the near future. Conclusions We still consider that appendicitis is not a medical disease but a surgical disease. This study revealed that delayed appendectomy was safe and feasible for adult patients with appendicitis although the clinical outcomes of delayed appendectomy were not superior to those of early appendectomy. Therefore, we suggest that surgeons would decide the appropriate timing of appendectomy with consideration other situations such as available hospital resources. References 1.
