Abstract
PURPOSE: In patients with cirrhosis, the Model for End-Stage Liver Disease Sodium (MELD-Na) score is a validated predictor of outcomes after transplant and non-transplant surgical procedures. This study investigates the association of MELD-Na score with complications following elective ventral hernia repair in non-cirrhotic patients. METHODS: The ACS NSQIP database was queried (2005-2016) for all elective laparoscopic and open ventral hernia procedures in patients without ascites or esophageal varices. Postoperative outcomes were compared by MELD-Na score using Chi-square tests. Multivariate logistic regression was used to control for potentially confounding variables. RESULTS: A total of 48,955 elective hernia repairs were identified; 68.7% were open repairs. The overall complication rate (Clavien-Dindo ≥ 1) was 14.3%, with a wound complication rate of 5.5%, and major complication rate (Clavien-Dindo ≥ 3) of 4.3%. A preoperative MELD-Na score ≥ 10 was present in 29.4%. Incremental increases in MELD-Na score (10-14, 15-19, and ≥ 20) were associated with increased overall complications (OR 1.25, CI 1.31-1.37; OR 1.53, CI 1.30-1.80; OR 1.70, CI 1.24-2.31, respectively), major complications (OR 1.42, CI 1.20-1.69; OR 1.85, CI 1.43-2.39; OR 2.13, CI 1.35-3.38, respectively), 30-day mortality (OR 1.58, CI 1.05-2.37; OR 2.34, CI 1.39-3.96; OR 3.16, CI 1.37-7.28, respectively), and return to the operating room (OR 1.19, CI 1.01-1.41; OR 1.38, CI 1.05-1.81; OR 1.78, CI 1.10-2.90, respectively). CONCLUSION: MELD-Na score is independently associated with postoperative complications in ventral hernia repair. As an objective and simple predictive model, it may be useful in preoperative risk calculations for complex patients.
