Perforated appendicitis: The solution to pollution is not dilution.

Area of Science:

• Pediatric Surgery
• Laparoscopic Surgery
• Infectious Disease Complications

Background:

• Traditional surgical principles suggest dilution as the solution to contamination.
• The study investigates withholding irrigation during Single Incision Laparoscopic Surgery (SILS) appendectomies for perforated appendicitis.
• A hypothesis was formed that omitting irrigation would reduce postoperative abscess rates.

Purpose of the Study:

• To evaluate the impact of withholding irrigation on postoperative abscess rates in pediatric SILS appendectomies.
• To determine if eliminating irrigation during these procedures affects surgical outcomes.

Main Methods:

• Retrospective review of 46 patients who underwent SILS appendectomy with irrigation (Group I) and 91 patients without irrigation (Group NI).
• Comparison of postoperative abscess rates between the two groups.
• Analysis of operative duration in relation to abscess formation.

Main Results:

• The abscess rate decreased from 19.6% in the Irrigation Group to 9.9% in the Non-Irrigation Group, though not statistically significant (p=0.12).
• Operative duration was significantly longer in patients who developed postoperative abscesses in the Non-Irrigation Group (OR 1.67, p=0.002) and overall (OR 1.45, p=0.0002).

Conclusions:

• Withholding irrigation during SILS appendectomies for perforated appendicitis demonstrated a trend towards reduced postoperative abscess rates.
• Increased operative times were associated with the development of postoperative abscesses.
