Advantages of abandoning abdominal cavity irrigation and drainage in operations performed on children with perforated appendicitis.
OBJECTIVE
This study evaluates the effect of peritoneal irrigation and drainage on postoperative morbidity when used together for perforated appendicitis.


METHODS
This study was conducted on children undergoing open appendectomy for perforated appendicitis. Sixty-one children with perforated appendicitis operated on with irrigation and drainage between July 1998 and September 2001 (group DI) and 173 children with perforated appendicitis who underwent surgery without irrigation and drainage (group NDI) between October 2001 and November 2011 were retrospectively evaluated (a total of 234 patients). All patients were treated and followed up by the same pediatric surgeon using the same protocol. Both groups were compared in respect to postoperative complications, including wound infection, wound dehiscence, intraabdominal abscess, prolonged ileus, the presence of small bowel obstruction requiring surgery, operative time, and length of postoperative hospital stay.


RESULTS
Of the total 234 patients, 151 were male and 83 were female with a mean age of 8.9 ± 3.7 years (range, 1.5-15 years). The wound infection rates were 4.9% in group DI and 1.7% in group NDI (P = .184). Wound dehiscence was seen in 1.6% vs 0%, prolonged ileus in 8% vs 2.3%, intraabdominal abscess in 4.9% vs 1.7%, and small bowel obstruction requiring surgery in 1.6% vs 0.6% of the patients (P = .261, P = .054, P = .184, and P = .454, respectively). No statistically significant difference in postoperative infectious complications was found between both groups. The length of postoperative hospital stay was 9.9 ± 4.1 days in group DI vs 6.3 ± 2.4 days in group NDI (P < .001). The operation times were 39 ± 8 and 31 ± 11 minutes, respectively (P < .001).


CONCLUSIONS
This study demonstrates that peritoneal irrigation and drainage in children with perforated appendicitis is not required, and in fact, these procedures cause an increase in operative time.
