Abstract Background Indications for repair of hiatal and paraesophageal hernia (HH/PEH) repair evolved significantly over the past two decades, impacted by the increasing application of minimally invasive surgical (MIS) approaches. This transition underscores the importance of evaluating the operative trends and clinical outcomes associated with open (open), laparoscopic (lap), and robotic surgeries especially in cases of giant hernias (over 50% intrathoracic stomach). Understanding these dynamics is crucial, especially as MIS becomes increasingly prevalent in managing complex cases, including giant hernias. The aim of this study is to assess critical outcomes achieved during the evolution from open to lap to robotic HH/PEH repair in a high volume center. Methods This is a retrospective review of 1834 patients undergoing open (958), lap (390), and robot (486), consecutive HH/PEH repairs prospectively entered into an IRB approved database from 2000 to 2023 at a high-volume center. Patient demographics, operative techniques, and top three most common presenting symptoms were studied overtime. Impact of operative technique, hernia type and size, operative outcomes including length of stay (LOS), radiographic recurrence (esophagram at 3 and 12 months), revisional surgery, on post-operative symptom resolution was evaluated. Results Annual volume increased overtime, with 418 repairs (78% robotic) in the last two years. Average hernia size decreased over the study period. The majority of patients (99.1%) presented with symptoms (Fig 1) and robotic repair had significantly better symptomatic resolution than open surgery (p0.05). This advantage persists with symptoms in giant hernias (p.001) LOS decreased over the study period (Fig 1). Overall radiographic recurrence (8.6%) and reoperative rate (2.4%) did not differ among operative techniques, however robotic repair had higher radiographic recurrence rate in case of giant hernia (18%, p.001). Conclusion The operative volume of HH/PEH repair has increased overtime associated with the increased application along with advancements in MIS and robotic operative techniques. Surgical interventions markedly ameliorate HH/PEH symptoms, with greater improvement observed in large hernia cases. Significant improvement in LOS and at least equivalent clinical results favors MIS, particularly robotic surgery. Although the incidence of anatomic recurrent hernia and reoperation is relatively low continued assessment of especially robotic operations to decrease this incidence further is warranted.
