Complicated Surgical Site Infection with Mycobacterium Abscessus After Liposuction and Affections of Corticosteroids in the Treatment Regimen: Three Cases Report and a Systematic Review.

[INTRODUCTION] Mycobacterium abscessus infection after liposuction/fat grafting is a rare complication that is hard to diagnose and treat. Misdiagnosis could result in treatment failure and prolonged hospital stays. The paradoxical reaction is another complication that rarely occurs in non-HIV patients infected with nontuberculosis mycobacteria. This study reported 3 cases infected with M. abscessus complicated by the paradoxical reaction after liposuction and fat grafting. It highlighted characteristics giving clues of the paradoxical reaction and a successful strategy. Also, a systematic review was conducted to comprehensively provide varied aspects of M. abscessus infection after liposuction and/or fat grafting.

[METHODS] Three cases were retrospectively included reporting data characteristics of patients, cosmetic procedures, and treatment strategy. PubMed, Scopus, Virtual Health Library (VHL), and Global Health Library (GHL) were searched to find and include cases with M. abscessus infection after liposuction and/or fat grafting based on defined selection criteria. Relevant data were extracted and summarized. The risk of bias in included studies was assessed using JBI critical appraisal checklists.

[RESULTS] Twenty-four articles were included in the systematic review. Symptoms often developed approximately 1 month after the cosmetic surgery. Culture, AFB, and PCR were common methods of diagnosis of M. abscessus after liposuction and/or fat grafting. It took about 33 days on average from the presentation to isolate and detect the pathogens. Antibiotics based on susceptibility testing results along with surgical interventions were effective methods of treatment. Our three cases which were complicated by the paradox were addressed by adding methylprednisolone for 2 weeks to the macrolide-based therapy.

[CONCLUSIONS] Awareness of this disease should be widely raised among physicians for early diagnosis and proper treatments. Cultures of specimens and AFB should be repeated many times before excluding the possibility of Mycobacterium spp. A paradoxical reaction should be suspected if the symptoms were worse after the antibiotic therapy based on susceptibility testing results and proper surgical interventions, especially if patients had taken corticosteroids before being admitted.
