Transumbilical laparoscopic-assisted appendectomy (TULAA) is one of the first endoscopic surgeries performed by trainee pediatric surgeons. While the operative time is generally shorter than for conventional laparoscopic appendectomy, the indications for this procedure are unclear and many unknown factors can prolong the operative time. We conducted this study to identify the factors that may prolong the operative time for TULAA. This retrospective, single-center study was conducted between 2015 and 2023. We performed multivariate analysis to identify the factors associated with prolonged operative time by analyzing TULAA procedures performed by trainees. The study included 243 patients. The median operative time was 84 min (interquartile range, 69-114 min). Multivariate analysis revealed that an increased body mass index, elevated C-reactive protein level, a history of conservative treatment for acute appendicitis, and appendix perforation, for the patient;
