Purpose: To compare the surgical outcomes of peritoneal irrigation versus suction alone during laparoscopic appendectomy and to identify the risk factors of surgical site infection in patients with uncomplicated acute appendicitis.
Methods: Data from patients with uncomplicated acute appendicitis between January 2014 and March 2016 were reviewed. We compared the irrigation and suction alone groups with regard to the following parameters: postoperative complication incidence rate, length of hospital stay, operation time, time to flatus, time to diet commencement, and duration of postoperative antibiotic.
Results: A total of 578 patients underwent laparoscopic appendectomy for uncomplicated acute appendicitis. Twenty-five patients were excluded from the analysis because of need for drain insertion, loss to follow-up, simultaneous surgery for another indication, presence of an appendix tumor, or pregnancy. A total of 207 patients (37.4%) had undergone irrigation, and 346 patients (62.6%) received suction alone during laparoscopic appendectomy. The preoperative fever rate was significantly higher in the irrigation group than in the suction alone group. Operative time was also significantly longer in the irrigation group than in the suction alone group (53.8 ± 18.5 minutes vs. 57.8 ± 21.4 minutes, P = 0.027). The postoperative complication rate was higher in the irrigation group than in the suction alone group (4.5% vs. 12.6%, P = 0.001). Multiple logistic regression analysis showed that irrigation and preoperative fever were risk factors for surgical site infection after laparoscopic appendectomy for uncomplicated acute appendicitis.
Conclusion: There is no advantage to irrigating the peritoneal cavity over suction alone during laparoscopic appendectomy for uncomplicated acute appendicitis. Irrigation may actually prolong the operative time and therefore be detrimental.
