Abstract

© 2016 Wiley Periodicals, Inc. Introduction: The aim of this study was to determine thymectomy-associated morbidity and mortality outcomes among myasthenia gravis (MG) patients. Methods: Patients undergoing thymectomy were identified from the National Surgical Quality Improvement Program database from 2005 to 2012 using Current Procedural Terminology codes. Patient demographics, clinical characteristics, and postoperative outcomes were stratified by MG diagnosis. Logistic regression was used to identify predictors for morbidity outcomes. The chi-square test was used to examine the association between MG diagnosis and surgical approach. Results: A total of 1,148 subjects underwent thymectomy, and 108 had MG. Compared with control subjects, MG patients had a more severe American Society of Anesthesiologists physical classification and frailty index score, greater corticosteroid usage, and a higher rate of reintubation. There were no deaths among MG patients. The majority of MG patients underwent transsternal thymectomy. Conclusion: Although patients with MG have a greater preoperative morbidity and a higher frequency of reintubation, thymectomy was found to be a safe procedure overall.
