Purpose: Excessive working hours have been reported to contribute to burnout among surgeons. In Japan, work-style reform is a problem that needs immediate attention. Acute appendectomy, which often occurs at nighttime, is one of the most common emergency surgeries. The feasibility of delayed and interval appendectomy remains to be investigated.
Methods: Two hundred forty-five consecutive patients who underwent laparoscopic appendectomy in our hospital were enrolled. They were divided into three groups: emergency appendectomy (immediate surgery, soon after the diagnosis [EA group], n = 153), delayed appendectomy (surgery during daytime the following day [DA group], n = 38) and interval appendectomy (antibiotics treatment followed by selective surgery three to four months later [IA group], n = 54). The clinical background and surgical outcomes were compared. Next, the residents' excess working time per month was calculated.
Results: The surgical outcomes (operation time, blood loss, length of hospital stay, postoperative complications) were similar between the EA and DA groups. However, no DA was performed during nighttime hours whereas 15.7% of EA was performed during nighttime hours (p = 0.0007). The surgical outcomes of the IA group were also comparable. The residents' excess working time declined following the introduction of DA and workstyle reform.
Conclusion: Delayed and interval laparoscopic appendectomy are feasible, and can be performed to promote workstyle reform without impairing patient safety.
