Effectiveness of Adjunctive Measures to Limit Recurrence and Reoperation After Laparoscopic Repair of Large Paraesophageal Hernias: A Single-Institution Series

Background: Despite surgical repair, large paraesophageal hernias (PEHs) often recur. To minimize recurrence, adjunctive measures, such as mesh and gastropexy, have been explored, but their impact on recurrence and reoperation rates remains unclear. Therefore, we analyzed our single-institution case series, where absorbable hiatal overlay mesh and percutaneous endoscopic gastrostomy (PEG) placement were utilized systematically.

Methods: Patients undergoing laparoscopic large PEH repair by a single surgeon between 1 January 2006 and 31 May 2021 were identified. Demographic data, hernia size, number of hiatal sutures used, use of mesh and/or PEG, fundoplication type, and complications were extracted by retrospective chart review. Hernia recurrence was assessed though postoperative radiographic and endoscopic studies or need for reoperation. Fisher’s exact, chi-square, Mood’s two-median and t-tests were used for between-group comparisons. Generalized linear models were used to assess associations between mesh and PEG placement and number of hiatal sutures and to compare risk differences for recurrence between treatment types (partial versus complete fundoplication; mesh versus no mesh; and PEG versus no PEG). Kaplan–Meier estimator with log-rank test was used to assess time to recurrence.

Results: Overall, 413 patients (median age 66 years) underwent laparoscopic large PEH repair and fundoplication (51% partial and 49% complete fundoplications). Of these, 78% had overlay absorbable mesh and 51% had a PEG. With an average follow-up time of over 5 years, we found 19.9% had radiographic or endoscopic recurrence. Although cohort stratification based on mesh implementation and fundoplication type did not identify differences in recurrence rates, significantly lower recurrence rates were noted in patients with PEG compared to no-PEG (14.8% vs. 23.5%, p = 0.01). Notably, of five reoperations, all were in complete fundoplication patients, and one occurred in a patient with PEG placement at the index operation.

Conclusions: PEG placement during laparoscopic PEH repair may lead to fewer recurrences in high-risk patients. Future prospective studies are warranted.
