Summary
Laparoscopic appendectomy reduces wound infections and speeds recovery compared to open surgery. However, longer operating times and a slight increase in intra-abdominal abscesses were noted.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Gastrointestinal Surgery
Background:
- Acute appendicitis is a common surgical emergency.
- Laparoscopic appendectomy offers potential benefits over traditional open surgery.
Purpose of the Study:
- To compare the effectiveness and safety of laparoscopic versus open appendectomy.
- Evaluate outcomes including complications, recovery time, and pain.
Main Methods:
- Meta-analysis of 28 randomized controlled trials.
- Pooled data from 2877 patients using a random-effects model.
- Analyzed outcomes such as operating time, infection rates, and hospital stay.
Main Results:
- Laparoscopic appendectomy was associated with reduced wound infections and shorter hospital stays.
- Patients undergoing laparoscopic surgery returned to full fitness earlier.
- Operating time was longer for laparoscopy, and intra-abdominal abscesses occurred slightly more frequently.
Conclusions:
- Laparoscopic appendectomy improves postoperative recovery and reduces wound infections.
- Methodological limitations in primary studies impact generalizability.
- Further research may be needed to fully clarify risks and benefits.
