Abstract

OBJECTIVE

To identify risk factors related to Mycobacterium abscessus subsp. bolletii infection during an outbreak, associated with laparoscopic surgery and to propose recommendations for preventing new cases.

DESIGN

A retrospective cohort study.

SETTING

A private hospital in Manaus, Brazil.

PATIENTS

A cohort of 222 patients who underwent laparoscopic surgery between July 2009 and August 2010 by a single surgical team.

METHODS

We collected information about the patients and the surgical procedure using a standard form. We included sex, age, and variables with P≤0.2 in the bivariate analysis in a logistic regression model. Additionally, we reviewed the procedures for reprocessing the laparoscopic surgery equipment, and the strains obtained with culture were identified by molecular methods.

RESULTS

We recorded 60 (27%) cases of infection. After multivariate analysis, the duration of surgery beyond 1 hour (odds ratio [OR] 2.4; 95% confidence interval [CI] 1.2–4.5), not to have been the first operated patient on a given day (OR, 2.7; 95% CI, 1.4–5.2), and the use of permanent trocar (OR, 2.2; 95% CI, 1.1–4.2) were associated with infection. We observed that the surgical team attempted to sterilize the equipment in glutaraldehyde solution when sanitary authorities had already prohibited it. Eleven strains presented 100% DNA identity with a single strain, known as BRA100 clone.

CONCLUSIONS

Because contaminated material can act as vehicle for infection, ensuring adequate sterilization processing of video-assisted surgery equipment was crucial to stopping this single clonal outbreak of nonturbeculous mycobacteria in Brazil.
