Laparoscopic versus open appendectomy in children with uncomplicated and complicated appendicitis.

PURPOSE: To address whether laparoscopic appendectomy could be an alternative to conventional open appendectomy in children with complicated appendicitis as well as uncomplicated appendicitis, a retrospective study comparing laparoscopic and open appendectomies was performed.
METHODS: One hundred patients who were treated by immediate appendectomy, either laparoscopically or by the open method, between May 2000 and August 2003 were included in the study. There were 53 patients in the laparoscopic appendectomy group and 47 patients in the open appendectomy group.
RESULTS: The operating time was significantly longer for laparoscopic appendectomy than for open appendectomy (P < .001). The length of hospital stay was significantly shorter in laparoscopic appendectomy in patients with uncomplicated appendicitis (P = .001). Thirteen of the 100 patients (13.0%) had 15 postoperative complications including wound infection (n = 8), intraabdominal abscess (n = 4), stitch abscess (n = 2), and small bowel obstruction (n = 1). In both uncomplicated and complicated appendicitis, there was no significant difference between laparoscopic and open appendectomies in the complication rates, and the incidences of each complication did not differ between the procedures. Among the 14 patients with generalized peritonitis, postoperative complications were seen in 5 patients (35.7%). Although the presence of generalized peritonitis was associated significantly with postoperative complications (P = .017), there was no significant association between the procedure and complications. Overall treatment costs were increased by 26.0% in laparoscopic appendectomy.
CONCLUSIONS: Laparoscopic appendectomy should remain an option in children with uncomplicated and complicated appendicitis, and when laparoscopy is selected, consideration of the advantages and disadvantages of the procedure is essential.
