Nomogram for Predicting Difficult Laparoscopic Appendectomy

Recruiting

• Conditions: Emergencies

• Registration Number: NCT06818942
• Lead Sponsor: Shanghai 6th People's Hospital

Brief 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.

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.

Primary Outcome Measures

Name	Time	Method
Number of participants with postoperative complications	through study completion, an average of 1 year	Postoperative bleeding, surgical site infection and other complications
Hospitalization	1 day of discharge	days of hospitalization
Degree of pain	approximately 4 hours after surgery and on postoperative day 1	pain intensity was assessed using a standard visual analogue score, with a score of 0 to 10 corresponding to no pain to the most severe pain
Operative time	During surgery	operative time was defined as the duration from incision to closure, and was collected from anesthesia record sheet
