Association of preoperative workup and comorbidities with risk of gastroesophageal surgery failure.

Background: While surgical failure rates for fundoplication and hiatal hernia repair are low, there has been no clear evaluation of the preoperative risk factors associated with surgical failure. This study aimed to identify risk factors predisposing patients to surgical failure.

Methods: Patients who underwent antireflux surgery during a 3-year period were evaluated for evidence of surgical complications and placed accordingly into the failure or control group.
