Introduction: Esophagogastric junction outflow obstruction (EGJOO) is attributed to primary/idiopathic causes or secondary/mechanical causes, including hiatal hernias (HH). While patients with HH and EGJOO (HH+EGJOO) may undergo HH repair without myotomy, it is unclear if an underlying motility disorder is missed by therapy which addresses only the secondary EGJOO cause. The goal of this study was to determine if HH repair alone is sufficient management for HH+EGJOO patients. Methods: A retrospective review of patients who underwent HH repair between January 1, 2016 and January 31, 2020 was performed. Patients who underwent high-reso-lution esophageal manometry (HREM) within one year before HH repair were included. Patients with and without EGJOO on pre-operative HREM were compared. Results: Sixty-three patients were identified. Pre-opera-tive HREM findings included: 43 (68.3%) normal, 13 (20.6%) EGJOO, 4 (6.3%) minor disorder or peristalsis, 2 (3.2%) achalasia, and 1 (1.6%) major disorder of peristal-sis. No differences between patients with EGJOO or normal findings on pre-operative manometry were found in pre-operative demographics/risk factors, pre-operative symptoms, and pre-operative HREM, except higher integrated relaxation pressure in EGJOO patients. No differences were noted in length of stay, 30-day complications, long-term persistent symptoms, or recurrence with mean fol-low-up of 26-months. Of the 3 (23.1%) EGJOO patients with persistent symptoms, 2 underwent HREM demon-strating persistent EGJOO and none required endo-scopic/surgical myotomy. Conclusion: Most HH+EGJOO patients experienced symptom resolution following HH repair alone and none required additional intervention to address a missed primary motility disorder. Further study is required to determine optimal management of patients with persistent EGJOO following HH repair.
