Abstract

Purpose: High body mass index (BMI) increases the risk of postoperative complications and hernia recurrence after abdominal wall reconstruction (AWR). However, BMI does not provide specific information on the mass and distribution of adipose tissue. We hypothesized that visceral fat volume (VFV) was a better predictor than BMI for recurrence after AWR. Methods: We included all patients undergoing AWR at our institution from November 2010 to December 2016. Data were collected from a prospective database and all patients were summoned for follow-up. VFV was calculated from preoperative CT. The primary and secondary outcomes were hernia recurrence and 30-day postoperative surgical site occurrences (SSO), respectively. Results: We included a total of 154 patients. At follow-up, 42 (27.3%) patients had developed recurrence. The recurrence rate was significantly higher in patients with a VFV higher than the mean compared to a VFV lower than the mean, P = 0.004. After multivariable Cox-regression, VFV remained significantly predictive of recurrence (HR 1.09 per 0.5 L increase of VFV, P = 0.018). In contrary, BMI was not associated with hernia recurrence. There was no significant difference in the rate of SSO between patients with a VFV above and below the mean. A multivariable logistic regression model showed that VFV was significantly associated with development of SSO (OR 1.12 per 0.5 L increase, P = 0.009). Conclusion: VFV was significantly associated with recurrence and SSOs after AWR. This study suggests VFV as a risk assessment tool for patients undergoing AWR.
