Overview
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.
Detailed description
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.
Interventions
- Other Observations on preoperative and intraoperative factors influencing the difficulty of surgery
Age, body mass index, gender, inflammatory indicators, previous history of abdominal surgery, underlying disease
Primary outcome measures
- Operative time [Time frame: During surgery]
- Number of participants with postoperative complications [Time frame: through study completion, an average of 1 year]
- Hospitalization [Time frame: 1 day of discharge]
- Degree of pain [Time frame: approximately 4 hours after surgery and on postoperative day 1]
Eligibility criteria
