    BackgroundThe natural history of hiatal herniation of small and/or large bowel post-esophagectomy (HHBPE) in the current era of improving long-term survival and evolving surgical technique is unknown. The aim of this study was to describe the rate and risk factors of HHBPE at our hospital.MethodsPatients undergoing esophagectomy between January 2011 and June 2017 were included if both follow-up information and axial imaging were available beyond 3 months post-esophagectomy. Patient characteristics, disease information, and treatment factors were all included in univariate analysis comparing patients with and without HHBPE, and multivariate regression was used to identify significant independent risk factors associated with HHBPE.ResultsOf 310 esophagectomy patients analyzed, 258 patients were included in the study, with 79 patients (31%) showing evidence of an HHBPE and an overall median follow-up of 24 months; 44 of 79 patients (56%) had symptoms possibly referable to HHBPE and 17 of 79 patients (22%) underwent surgical repair. On univariate analysis, neoadjuvant therapy (n = 176), higher clinical stage, minimally invasive approach (n = 154), and transhiatal esophagectomy (n = 189) were significant predictors of HHBPE (p < 0.05). On multivariate analysis, neoadjuvant therapy and transhiatal approach remained significant independent predictors (p < 0.05). The rate of HHBPE was 44% in the 131 patients (51%) that had both factors.ConclusionsHHBPE in the current era of neoadjuvant therapy and minimally invasive esophagectomy is common. HHBPE can cause gastrointestinal symptoms, but operation to repair HHBPE is uncommon on intermediate follow-up. Additional study and long-term follow-up are required to fully assess the impact of HHBPE and to potentially modify surgical practice to prevent or minimize HHBPE.Copyright © 2020 American College of Surgeons.
