Introduction:

Intra-abdominal abscesses are the post-appendectomy complications that most frequently cause hospital admissions.

Objective:

To study the risk factors for the appearance of post-appendectomy intra-abdominal abscesses.

Methods:

A retrospective study of patients over 14 years of age, operated on for suspected acute appendicitis by laparoscopic appendectomy, was performed from January 1, 2007 to December 31, 2010. Chi-square statistical tests, Fisher's exact test were used. Student's t and logistic regression.

Results:

During the 4 years of the study, 672 patients suffered with symptoms and signs compatible with acute appendicitis. An intra-abdominal abscess appeared in 35 cases (5.2%). In the multivariate analysis using logistic regression, the following possible risk factors were found: advanced forms of appendicitis (p <0.0001), which increased the risk by about 6 times (95% CI 2.2-14.9) and male sex (p = 0.033), could also increase the risk about 2.5 times (95% CI 1-6).

Conclusions:

Possible risk factors for the appearance of intra-abdominal abscesses after appendectomy are male sex and advanced stage, the latter being the most influential factor.
