Interval appendectomy (IA) shows better treatment results than does emergency appendectomy (EA) for complicated appendicitis (CA). However, the deviation cases of CA that are planned for IA undergo EA instead. In this study, we evaluated the treatment results of deviated cases and examined the validity of IA for CA. The study included 165 cases of CA diagnosed from January 2011 to August 2017. The results were classified into the EA, IA success (IA-S), and IA deviation (IA failure; IA-F) groups; the surgical results and hospitalization days were compared. In this study, the EA, IA-S, and IA-F groups comprised 95, 53, and 17 cases, respectively. The postoperative complication rates in EA, IA-S, and IA-F groups were 37.9％, 7.5％, and 11.7％, respectively: complication rates in the IA-S and IA-F groups were lower than those in the EA group. With respect to the amount of bleeding and operation time, outcomes in the IA-S group were superior to those of EA, and outcomes in the IA-F and EA groups were similar. The durations of hospitalization in EA, IA-S, and IA-F groups were 10, 13, and 10 days, respectively：hospitalization days in the EA and IA-F groups were equivalent. As IA has a low postoperative complication rate and the hospitalization days in the IA-F group were comparable to those associated with EA, we suggest that IA should be the first-choice treatment for CA.
