Predictors of Hiatal Hernia Recurrence After Laparoscopic Anti-reflux Surgery with Hiatal Hernia Repair: a Prospective Database Analysis

Abstract

BackgroundThe aim of this study is to identify factors that can predict hiatal hernia recurrence (HHR) in patients after anti-reflux surgery with hiatal hernia (HH) repair. MethodsA single-institution, prospectively collected database was reviewed (January 2002–October 2015) with inclusion criteria of GERD and laparoscopic anti-reflux (AR) surgery with HH repair. Demographics, esophageal symptom scores, and pre- and post-upper gastrointestinal imaging (UGI) were collected. Mesh usage, HH type (sliding, paraesophageal (HH) or type IV), and size were evaluated, and patients who had HHR versus those who did not (NHHR) were compared. Statistical analysis was performed using IBM SPSS v.23.0.0, with α = 0.05. ResultsThree hundred twenty-two patients met inclusion criteria. Mean age was 56.9±14.8 years (60.9% female), and mean follow-up was 19.9±23.8 months. 88.2% underwent total fundoplication and 11.8% underwent partial fundoplication. HHR rate was 15.5%. HHR patients had larger HH than the NHHR group. There was no significant difference between groups for age, gender, BMI, race, and mesh usage. Only 3 patients (10.3%) with HHR reported mild-to-moderate heartburn, regurgitation, and solid or liquid dysphagia at 12-month follow-up. Overall reoperation rate was 1% in this population. ConclusionsHHR is correlated with large hernia size. Mesh use and patient BMI were not predictors, and no correlation was identified between HHR and presence of GERD symptoms. Recurrence after repair is not uncommon, but is asymptomatic in most cases. Reoperation is rare and mesh is not routinely needed. Large asymptomatic HHs in the elderly often do not require intervention.
