Primary versus redo paraesophageal hiatal hernia repair: a comparative analysis of operative and quality of life outcomes

Introduction We compared patient outcomes after initial versus redo paraesophageal hernia (PEH) repair at two high-volume GI surgery centers. Materials and methods Retrospective review analyzed one-year outcomes after initial versus redo elective laparoscopic PEH repair, including wound/non-wound-related complications and quality of life benefits as measured by four validated instruments: reflux symptom index, gastroesophageal reflux disease health-related, laryngopharyngeal reflux, and swallowing scales. Results Three hundred and seventeen patients (271 initial and 46 redo) underwent laparoscopic PEH repair. Groups differed with respect to age (64.6 vs. 60.2 years, p = 0.027), but were comparable in gender (71.2 vs. 67.4% female, p = 0.596), BMI (29.0 vs. 27.6 kg/m 2 , p = 0.100), and ASA score (2.3 vs. 2.3 p = 0.666). Redo surgery was more complex with longer mean operative times (112.2 vs. 139.1 min, p
