Incidence of Hiatal Hernia Repair During Primary Bariatric Surgery Conversion: an Analysis of the 2020 MBSAQIP Database.

Abstract

The rate of hiatal hernia (HH) repair during conversion bariatric surgery is largely unknown. Wesought to determine this rate in 12,788 patients undergoing conversion surgery using the 2020 participant use fileof the MBSAQIP database. Concurrent HH repair was performed in 24.1% of conversion cases; most commonlyduring SG to RYGB (33.1%), followed by AGB to SG conversion (20.2%). The remaining conversion pathways hada repair rate around 13%. Only 12.1% of HH repairs were performed using a mesh. GERD was the primaryindication for conversion in 65% of the SG to RYGB cases. A much higher proportion of patients with concomitantHH repair reported GERD as the main reason for conversion than those without a HH repair (44.5% vs. 23.7%;p<0.001).
