Abstract:
Purpose:Laparoscopic appendectomy, a routine surgical procedure for acute appendicitis, is commonly performed in general hospitals. However, postoperative outcomes based on surgical subspecialty have not been well established. This study aimed to compare surgical outcomes of laparoscopic appendectomy across different surgical subspecialties using risk-adjusted cumulative summation (RA-CUSUM) analysis.
Methods:A retrospective analysis was conducted on 631 patients undergoing laparoscopic appendectomy between July 2020 and December 2022. Surgeons were categorized into gastrointestinal (GI) or non-GI groups and senior or young groups. Surgical failure was defined as operation time exceeding the mean plus 2 standard deviations, presence of postoperative complications, or readmission within 30 days after surgery. RA-CUSUM analysis was employed to evaluate surgical failure within each group.
Results:The GI group performed more partial cecectomies (P = 0.017) and had longer operation times (P = 0.019) than the non-GI group. The senior group exhibited shorter operation time (P < 0.001), reduced length of stay (P = 0.011), and a higher complication rate (P < 0.001) than the young group. RA-CUSUM analysis indicated a decrease in surgical failure as accumulation progressed in both senior and young groups, as well as in the GI and non-GI groups.
Conclusion:Outcomes of laparoscopic appendectomy varied by subspecialty and length of experience. However, each surgeon showed trends of decreasing surgical failure over time. These results suggest that the surgeon’s subspecialty minimally affects the outcomes of laparoscopic appendectomy, reflecting its fundamental nature within general surgery.
