Condition(s) studied

Investigational drug(s) / intervention(s)

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

Study summary

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

  operative time was defined as the duration from incision to closure, and was collected from anesthesia record sheet
• Number of participants with postoperative complications — through study completion, an average of 1 year
