Background. Many aspects of the management of perforated appendicitis
In children remain controversial. The objective of this study was to d
efine risk factors associated with the development of postoperative co
mplications in children undergoing treatment for perforated appendicit
is. Methods. We reviewed all children (age < 16 years) who were treate
d for perforated appendicitis at Cardinal Glennon Children's Hospital
between 1988 and 1997. Inclusion criteria included either gross or mic
roscopic evidence of appendiceal perforation. Results. Of 285 children
with perforated appendicitis, 279 underwent immediate operative treat
ment. Mean patient age was 7.7 years and there were no deaths. Major p
ostoperative complications included intra-abdominal abscess (n = 17),
ileus (n = 7), mechanical intestinal obstruction (n = 6) and wound inf
ection (n = 4). All children who had a postoperative abscess had more
than 5 days of symptoms before operation. Within this subgroup, drain
placement was associated with not only decreased postoperative abscess
formation and but also shorter duration of fever and length of hospit
alization. The incidence of mechanical obstruction or ileus was not in
creased and the rate of wound infection was actually lower after drain
age. Conclusions. Drain placement appears to be helpful in children wi
th late diagnosis but is of little benefit when the duration of sympto
ms is less than 5 days. Thus it is likely that drains are most useful
in patients With well-established and localized abscess cavities.
