Risk factors for antibiotic therapy failure in women with tubo‐ovarian abscess: A systematic review and meta‐analysis

Abstract Aim Medical therapy with antibiotics only and surgical drainage are the treatment options of tubo‐ovarian abscess (TOA). It is not yet known exactly which cases need surgical treatment. The aim of this systematic review and meta‐analysis was to evaluate the risk factors leading antibiotic therapy failure in women with TOA. Methods We searched the following databases from inception to June 1, 2022: PubMed, Ovid MEDLINE, The Cochrane Library, and Scopus. We also searched reference lists of eligible articles and related review articles. The observational cohort, cross‐sectional, and case–control studies were included in the meta‐analysis. At least four review authors independently selected eligible articles, assessed risk of bias, and extracted data. The random effect model was used in the meta‐analysis. Results A total of 29 studies, including 2890 women, were included in the study. The age, abscess size, history of intrauterine device use, postmenopausal status, history of diabetes mellitus, fever, white blood cell count, erythrocyte sedimentation rate, C‐reactive protein level, and history of pelvic inflammatory disease were found as significant risk factors for antibiotic therapy failure in women with TOA. Conclusions The findings of this study clarified the risk factors for antibiotic therapy failure in women with TOA.
