Outcomes of concomitant ventral hernia repair performed during bariatric surgery

Abstract

Background

Currently there is no consensus on management of ventral hernias encountered during bariatric surgery (BS). This study aims to evaluate the incidence and outcomes of concomitant ventral hernia repair (VHR) during BS at our institution.

Methods

Patients who had concomitant VHR during BS from 2004 to 2015 were identified. Data collected included baseline demographics, comorbidities, perioperative parameters, surgical approach and postoperative outcomes.

Results

A total of 159 patients underwent concomitant VHR during the study period at the time of BS. One hundred and one (64 %) patients were female; median age was 53 years (IQR 45.0–60.3) and median BMI was 48.2 kg/m² (IQR 41.6–54.1). Comorbidities included: hypertension (n = 124, 78 %), type 2 diabetes (n = 103, 65 %), hyperlipidemia (n = 100, 63 %), obstructive sleep apnea (n = 98, 62 %) and reflux disease (n = 54, 34 %). Out of 159 patients, 41 patients (26 %) had a prior VHR. Out of 103 patients, 69 patients (67 %) had a previous abdominal surgery. Of the concomitant VHR, 144 (91 %) were completed laparoscopically, 12 (7 %) patients were converted to open surgery and 3 (2 %) patients underwent primary open procedures. Technique included primary suture closure in 115 (72 %) and mesh repair in 44. Early postoperative complications (<30 days) were reported in 16 (10 %) patients, with superficial wound infection (n = 9), bowel obstruction (n = 2), marginal ulcer (n = 2), DVT (n = 1) and pneumonia (n = 1). Hernia recurrence was reported in 3 patients (2 %) in the early post-op period and in 40 patients (25 %) as a late (>30 days) complication. Surgery for recurrent hernia was performed in 31/42 patients during follow-up. At 12-month follow-up, median BMI and % excess weight loss were 34.2 kg/m² (IQR 29.5–40.9) and 59.6 % (IQR 44.9–74.8 %), respectively.

Conclusion

Ventral hernia is a common finding in patients undergoing BS. Both primary suture repair and mesh repair result in acceptable results, both in terms of recurrence and perioperative complications.
