Abstract
BACKGROUND: Metabolic and bariatric surgery (MBS) has a low incidence of post-operative morbidity and mortality. Understanding risk factors associated with complications that occur allows surgeons to define at-risk patients and assess the need for preventive and prophylactic measures. OBJECTIVES: To determine risk factors associated with development of pulmonary embolism (PE) within 30 days of MBS and to predict the increased risk for mortality when PE occurs. SETTING: USA, MBSAQIP database. METHODS: Analysis of the MBSAQIP database was undertaken. This included information on 966,646 MBS cases from 2015 to 2019 in the USA. RESULTS: Twenty-two risk factors for development of PE post-MBS were identified to be statistically significant. CONCLUSIONS: PE is a relatively uncommon complication after MBS. When it does occur, there is a 50.9-fold increased risk for mortality. Patients with significant risk factors for PE may benefit from higher dose perioperative and/or extended VTE prophylaxis after MBS.
