This meta-analysis of randomized clinical trials (RCT) aimed to compare peritoneal irrigation followed by suction with aspiration only during laparoscopic surgery for complicated appendicitis (LA). PRISMA guidelines with the random-effects model were adopted using Review Manager Version 5.3 for pooled estimates. We retained six eligible RCT published between 2012 and 2019. They involved a total of 1019 patients (541 patients in the aspiration group and 478 patients in the irrigation group). Aspiration only during LA is associated with shorter operative time (MD = 8.50 min, 95% CI [− 12.97 to − 4.02], p = 0.0002) and lower reoperation rate (OR = 0.37 95% CI [0.14–0.96], p = 0.04). There was no difference between aspiration group and irrigation group in terms of Intraperitoneal abscess (IPA) (OR = 0.99 95% CI [0.54–1.81], p = 0.95), morbidity rate (OR = 1.14 95% CI [0.44–2.98], p = 0.79), wound infection (OR = 0.94 95% CI [0.20–4.40], p = 0.94), and hospital stay (MD = 0.65 day, 95% CI [− 0.52 to 1.82], p = 0.27). Irrigation during LA prevents post-appendectomy IPA in neither adults nor pediatric patients. However, it lengthens the operative time and involves a higher reoperation rate.
