Higher Edmonton Obesity Staging System scores are associated with complications following laparoscopic Roux-en-Y gastric bypass.

Background: The Edmonton Obesity Staging System (EOSS) is a staging system describing comorbidities and functional limitations associated with obesity, thus facilitating the prioritization of patients for bariatric surgery. Our objective was to elucidate any associations of EOSS scores with major complications after laparoscopic Roux-en-Y gastric bypass (LRYGB).

Methods: A retrospective chart review examined patients who received primary LRYGB from 2009 to 2015 at a single center.
