Background:
Postappendectomy intra-abdominal abscesses (PAIAA) complicate the recovery of a small but significant fraction of patients with advanced appendicitis.
Study Design:
A retrospective review of 1,184 patients with appendicitis was undertaken to define the clinical characteristics and risk factors associated with PAIAA.
Results:
Thirty-three patients with 36 PAIAAs were found, an incidence of 2.8 percent. The mean age of patients with PAIAA was less than the overall group (16.9 versus 23.1 years, p = 0.002), and the mean core temperature of the PAIAA group was significantly higher (38.5 versus 38.2 degrees C). The incidence of PAIAA increased as the degree of appendiceal pathology worsened. The incidence of PAIAA was six (3.2 percent) of 190 in patients with gangrenous appendicitis and was 27 (8.7 percent) of 309 among patients with perforated appendicitis. Logistic regression analysis showed that independent predictors for the occurrence of PAIAA were young age and perforation. Although children presented with a higher rate of perforated appendicitis, this did not account for the younger age of the patients with PAIAA. Children (less than ten years of age) with perforation had PAIAA in ten (14 percent) of 69 cases compared with the incidence in the older patients with perforation of 17 (7.1 percent) of 240.
Conclusions:
These findings improve the surgeon's ability to identify patients at risk for PAIAA. Alterations in the perioperative management of perforated appendicitis, particularly in the pediatric patient, may reduce the occurrence of PAIAA.
Insights
Younger patients and those with perforated appendicitis face a higher risk of developing postappendectomy intra-abdominal abscesses (PAIAA). Early identification and tailored perioperative management, especially in pediatric cases, can help reduce PAIAA incidence.
Area of Science:
- Surgical outcomes
- Gastrointestinal surgery
- Pediatric surgery
Background:
- Postappendectomy intra-abdominal abscesses (PAIAA) are a known complication following appendicitis treatment.
- Identifying patients at risk for PAIAA is crucial for improving recovery and preventing complications.
Purpose of the Study:
- To define the clinical characteristics and risk factors associated with PAIAA.
- To improve the ability of surgeons to identify patients at risk for PAIAA.
Main Methods:
- Retrospective review of 1,184 patients with appendicitis.
- Analysis of clinical characteristics and risk factors for PAIAA development.
Main Results:
- The incidence of PAIAA was 2.8% (33/1184 patients).
- Younger age (mean 16.9 vs 23.1 years) and higher core temperature were associated with PAIAA.
- Independent predictors for PAIAA were young age and perforation; incidence increased with appendiceal pathology severity, particularly in perforated appendicitis (8.7%).
- Children under ten with perforation had a 14% PAIAA rate compared to 7.1% in older patients with perforation.
Conclusions:
- Younger age and appendiceal perforation are significant independent predictors of PAIAA.
- Perioperative management strategies, especially for pediatric patients with perforated appendicitis, may reduce PAIAA occurrence.
