About this trial
No prior studies have stratified the difficulty of laparoscopic appendectomy (LA). The investigators aimed to investigate preoperative factors as indicators of difficult LAs based on the experience of surgical trainees and to develop a predictive model accordingly.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Clinical diagnosis of acute appendicitis
Participants who underwent laparoscopic appendectomy
Disqualifiers
Participants refused or could not tolerate laparoscopic appendectomy
Incomplete preoperative examination or missed information
Trial population
Patients with confirmed acute appendicitis, were willing to and suitable to undergo laparoscopic appendectomy (LA). Patients were well informed about the surgical procedure and were aware of the potential benefits and risks. Patient consented for us to use perioperative data.
