Irrigation versus suction alone during laparoscopic appendectomy for perforated appendicitis: a prospective...

Area of Science:

• Pediatric Surgery
• Gastrointestinal Surgery

Background:

• The necessity of peritoneal irrigation during laparoscopic appendectomy for perforated appendicitis remains debated.
• Prospective comparative data are limited, necessitating further research.

Purpose of the Study:

• To compare the efficacy of peritoneal irrigation versus suction alone during laparoscopic appendectomy for perforated appendicitis in children.
• To evaluate postoperative abscess rates and other clinical outcomes.

Main Methods:

• A prospective, randomized trial involving 220 children younger than 18 years with perforated appendicitis.
• Patients were randomized to receive either peritoneal irrigation (≥500 mL normal saline) or suction only during surgery.
• The primary outcome was the development of postoperative abscess; data were analyzed on an intention-to-treat basis.

Main Results:

• No significant difference in postoperative abscess rates between the irrigation group (18.3%) and the suction-only group (19.1%) (P = 1.0).
• Similar durations of hospitalization, mean hospital charges, and operative times were observed in both groups.
• Irrigation was deemed necessary in only one patient (0.9%) randomized to suction only.

Conclusions:

• Peritoneal irrigation provides no discernible advantage over suction alone in managing perforated appendicitis during laparoscopic appendectomy in children.
• The findings suggest that suction alone is a sufficient and effective method.
