Purpose : The aim of this retrospective study was to compare open (Mc
Burney incision group MB n = 92) and laparoscopic (group LAP n = 58) a
ppendectomy for complicated appendicitis (abscess or peritonitis). Mat
erial and method: 150 children, with a mean age of 8.5 years, were ope
rated in our department from January 1990 to April 1996. Only children
with complicated appendicitis and positive bacteriology of peritoneal
fluid were included in this study. All children received parenteral a
ntibiotics for an average of 5.3 days. Results : The mean operating ti
me was significantly longer in the LAP group (63 vs 43 min p<0.0001).
The conversion rate in the LAP group was 12%. The mean hospital stay w
as 8.4 days (3-29) without any difference between the 2 groups. There
was no significant difference for the complication rate in the 2 group
s, except for wound infections which were more frequent in the MB grou
p (p = 0.008). Late postoperative complications occurred in 3 cases in
the MB group (none in the LAP group) (NS). There were 2 small bowel o
bstructions and a wound dehiscence. Conclusion: Laparoscopic appendect
omy is a safe procedure for complicated appendicitis in children, but
the greatest short-term benefit is cosmetic. Long-term results have to
be evaluated, particularly with regards to the long-term complication
rate.
