Efficacy and Safety of Recurrent Paraesophageal Hernia Repair with Roux-en-Y Gastric Bypass

Roux-en-Y gastric bypass (RYGB) has been explored as a revisional option to failed paraesophageal hernia (PEH) repair with fundoplication, particularly in patients suffering from obesity. However, few studies have assessed long-term outcomes of RYGB with revisional PEH repairin regard to acid-suppressing medication use. We retrospectively identified 19 patients who underwent revisional PEH repair with RYGB between 2011 and 2018. The median operative time was 232 minutes with a median hospital length of stay of two days. The median length of follow-up was 24 months. Two patients (10.5%) had complications in the first 30 days, and five patients (26.3%) had complications within one year. Of the 12 patients on preoperative acid suppression, 6 (50%) were either off medication or on reduced dose at 12 months. The median BMI decrease was 14.4 kg/m2 at 12 months and did not change significantly afterward. Although rates of acid-suppression medication use did not change overall after revisional PEH repair with RYGB, patients experienced successful long-term management of morbid obesity and sustained weight loss. Revisional PEH repair with RYGB is a safe and effective option, with a complication rate comparable with the reported rates after revisional foregut procedures such as revisional Nissen fundoplication.
