Bariatric Surgery: Bridge for Ventral Hernia Repair?

Area of Science:

• Surgical outcomes
• Bariatric surgery
• Hernia repair

Background:

• Obesity is a known risk factor for complications and recurrence in ventral hernia repair (VHR).
• The specific impact of prior bariatric surgery on VHR outcomes remains under-investigated.
• This study examines elective VHR in patients with and without a history of bariatric surgery.

Purpose of the Study:

• To evaluate the outcomes of elective ventral hernia repair (VHR) in patients with a history of bariatric surgery.
• To compare postoperative complications and reoperation rates between obese patients with and without prior bariatric procedures.

Main Methods:

• Retrospective analysis of the IBM MarketScan® database (2000-2021).
• Inclusion of elective VHR patients: bariatric group vs. obese control group.
• Propensity score weighting to balance confounders; comparison of 30-day complications and 1, 3, 5-year reoperations.

Main Results:

• 10,468 patients included; 55.9% of the bariatric group remained obese at VHR.
• Bariatric group had lower comorbidity index but more concurrent operations.
• Higher incidence of hematoma/seroma drainage (3.7% vs 2.3%) and hernia reoperation (1, 3, 5 years: 7.8% vs 5.5%, 12.9% vs 9.9%, 14.7% vs 11%) in the bariatric group.

Conclusions:

• Patients with prior bariatric surgery demonstrated an increased risk of hernia reoperation after VHR.
• Weight loss from bariatric surgery may mitigate some VHR risks.
• Additional factors related to bariatric surgery and weight loss require careful consideration for VHR outcomes.
