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.
Acute appendicitis is the most common cause of surgical emergencies and laparoscopic appendectomy (LA) is usually attempted by surgical trainees. This study aim to explore the preoperative and intraoperative factors affecting the degree of surgical difficulty and to establish a model for validation, so that it can be subsequently replicated in training programs.
