Ventral hernias are a common finding during bariatric surgery; however, the risks and benefits of repair during surgery remain unclear. Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, we examined the short-term outcomes of patients undergoing bariatric surgery with concurrent ventral hernia repair (VHR) versus bariatric surgery alone.


Patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) were included. A propensity-matched analysis was performed between laparoscopic bariatric surgery with and without concurrent VHR. The primary outcome was the 30-day major complication rate which includes but is not limited to 30-day reoperation, deep surgical site infection, and sepsis. Secondary outcomes included operative time, length of hospital stay, 30-day readmission, and 30-day mortality.


A total of 430,225 patients were included, of which 4690 (1.1%) received concomitant VHR. With one-to-one propensity score matching, 4648 pairs were selected. Concurrent VHR was associated with a higher major complication rate (5.8 vs 3.8%, p < 0.001) but no significant difference in mortality (0.3 vs 0.2%, p = 0.531). Both LSG with VHR (3.2 vs 2.4%, p = 0.007) and RYGB with VHR (9.3 vs 5.7%, p < 0.001) were associated with an increase in major complications.


Patients undergoing VHR during bariatric surgery do not experience higher mortality. However, these patients have an elevated risk of major complications with this risk being higher among patients undergoing VHR and LRYGB. Bariatric surgeons should consider these risks when choosing to perform VHR at the time of bariatric surgery.
