Abstract
Background
The aims of this study were to assess the efficacy of percutaneous drainage of postoperative
abscess after abdominal surgery and to identify factors predictive of failed drainage.
Methods
Data from 81 patients with postoperative abdominopelvic abscesses treated with percutaneous
drainage were reviewed. Percutaneous drainage failure was considered when surgery
was needed to control the sepsis. Predictive variables were sought using univariate
and multivariate analyses with logistic regression models.
Results
Successful drainage requiring 1 (n = 46) or 2 (n = 17) procedures was observed in
63 patients (78%; 95% confidence interval, 67%–86%). Surgery was needed in 18 patients
(22%; 95% confidence interval, 14%–38%). Residual collection after a first percutaneous
drainage was the single predictive factor for failed drainage on univariate and multivariate
analyses (P = .0275).
Conclusions
Percutaneous imaging-guided drainage is a feasible and effective method for the treatment
of abdominopelvic abscess, with a success rate of 78%. Residual collection is an independent
predictor of unfavorable outcome after percutaneous drainage.
