Background: Laparoscopic appendectomy followed by postoperative intravenous (IV) antibiotics is the standard of care for acute appendicitis and postoperative prevention of intra-abdominal abscesses. The aim of or study was to determine if intraperitoneal irrigation with antibiotics could help prevent intra-abdominal abscess formation after laparoscopic appendectomy for complicated appendicitis in pediatric patients. 

Methods: A retrospective study was conducted on consecutive pediatric patients with acute appendicitis who had appendectomy in our Pediatric Surgery Department between August 2020 and February 2022. We compared two groups with similar age and symptoms. The first group (A) was treated with the normal standard of care, i.e., laparoscopic appendectomy and postoperative IV antibiotic therapy. For the second group (B) intraperitoneal cefazoline irrigation was added at the end of the laparoscopic procedure. Postoperative intra-abdominal abscess was diagnosed with ultrasound examination, performed after clinical suspicion/abnormal blood test results. 

Results: One hundred sixty patients (males:females 109:51; median age 10.5 years [range 3–17 years]) who had laparosopic appendectomy for complicated appendicitis were included, 82 in group A and 78 in group B. In the first 7 days after surgery, 18 patients in group and 5 in group B developed an intra-abdominal abscess (p < 0.005). Drains were positioned in 38 patients in group A vs. 9 in group B. One patient in group A had a different complication which was infection of the surgical incision. 

Conclusions: Intraperitoneal cefazoline irrigation at the end of the laparoscopic appendectomy in pediatric patients significantly reduces the formation of intra-abdominal abscesses
