Insights
Drain placement in children with perforated appendicitis is beneficial for late diagnoses, reducing abscesses and hospital stays. It is less effective for early symptom onset, suggesting utility in established abscesses.
Area of Science:
- Pediatric Surgery
- Gastrointestinal Surgery
- Infectious Disease Management
Background:
- Management of perforated appendicitis in children presents several controversial aspects.
- Identifying risk factors for postoperative complications is crucial for improving outcomes.
Purpose of the Study:
- To define risk factors for postoperative complications in pediatric perforated appendicitis.
- To evaluate the impact of drain placement on outcomes in this patient group.
Main Methods:
- Retrospective review of children under 16 with perforated appendicitis (1988-1997).
- Inclusion criteria: gross or microscopic evidence of appendiceal perforation.
- Analysis of postoperative complications and association with symptom duration and drain placement.
Main Results:
- 285 children treated, 279 with immediate surgery; mean age 7.7 years; no deaths.
- Major complications: intra-abdominal abscess (17), ileus (7), intestinal obstruction (6), wound infection (4).
- Children with >5 days symptoms and abscesses benefited from drain placement (reduced fever, shorter hospitalization, fewer abscesses).
Conclusions:
- Drain placement is beneficial for perforated appendicitis with symptom duration >5 days, particularly for localized abscesses.
- Drains offer limited benefit for early diagnoses (<5 days symptom duration).
- Drainage may help prevent or manage intra-abdominal abscesses in specific pediatric cases.
Background:
Many aspects of the management of perforated appendicitis in children remain controversial. The objective of this study was to define risk factors associated with the development of postoperative complications in children undergoing treatment for perforated appendicitis.
Methods:
We reviewed all children (age < 16 years) who were treated for perforated appendicitis at Cardinal Glennon Children's Hospital between 1988 and 1997. Inclusion criteria included either gross or microscopic evidence of appendiceal perforation.
Results:
Of 285 children with perforated appendicitis, 279 underwent immediate operative treatment. Mean patient age was 7.7 years and there were no deaths. Major postoperative complications included intra-abdominal abscess (n = 17), ileus (n = 7), mechanical intestinal obstruction (n = 6), and wound infection (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 hospitalization. The incidence of mechanical obstruction or ileus was not increased and the rate of wound infection was actually lower after drainage.
Conclusions:
Drain placement appears to be helpful in children with late diagnosis but is of little benefit when the duration of symptoms is less than 5 days. Thus it is likely that drains are most useful in patients with well-established and localized abscess cavities.
