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