Background:
Higher MELD scores correlate with adverse operative outcomes regardless of the presence of liver disease, but their impact on pancreatectomy outcomes remains undefined. We aimed to compare 30-day adverse postoperative outcomes of patients undergoing elective pancreatectomy stratified by MELD score.
Methods:
Elective pancreatoduodenectomies (PDs) and distal pancreatectomies (DPs) were identified from the 2014-2016 ACS NSQIP Procedure Targeted Pancreatectomy Participant Use Data Files. Outcomes examined included mortality, cardiopulmonary complications, prolonged postoperative length-of-stay, discharge not-to-home, transfusion, POPF, CR-POPF, any complication, and serious complication. Outcomes were compared between MELD score strata (< 11 vs. ≥ 11) as established by the United Network for Organ Sharing (UNOS). Multivariable logistic regression models were constructed to examine the risk-adjusted impact of MELD score on outcomes.
Results:
A total of 7580 PDs and 3295 DPs had evaluable MELD scores. Of these, 1701 PDs and 223 DPs had a MELD score ≥ 11. PDs with MELD ≥ 11 exhibited higher risk for mortality (OR = 2.07, p < 0.001), discharge not-to-home (OR = 1.26, p = 0.005), and transfusion (OR = 1.7, p < 0.001). DP patients with MELD ≥ 11 demonstrated prolonged LOS (OR = 1.75, p < 0.001), discharge not-to-home (OR = 1.83, p = 0.01), and transfusion (OR = 2.78, p < 0.001). In PD, MELD ≥ 11 was independently predictive of 30-day mortality (OR = 1.69, p = 0.007) and transfusion (OR = 1.55, p < 0.001). In DP, MELD ≥ 11 was independently predictive of prolonged LOS (OR = 1.42, p = 0.026) and transfusion (OR = 2.3, p < 0.001).
Conclusion:
A MELD score ≥ 11 is associated with a near twofold increase in the odds of mortality following pancreatoduodenectomy. The MELD score is an objective assessment that aids in risk-stratifying patients undergoing pancreatectomy.
Insights
Higher MELD scores (≥11) significantly increase mortality risk after pancreatoduodenectomy and adverse outcomes in distal pancreatectomy. The MELD score aids in stratifying pancreatectomy patient risk.
Area of Science:
- Surgical outcomes research
- Hepatology and gastroenterology
- Medical decision making
Background:
- Elevated Model for End-Stage Liver Disease (MELD) scores are linked to poor surgical outcomes, but their specific impact on pancreatectomy is unclear.
- This study investigates the association between MELD scores and 30-day adverse postoperative outcomes in patients undergoing elective pancreatectomy.
Purpose of the Study:
- To compare 30-day adverse postoperative outcomes in patients undergoing elective pancreatectomy, stratified by MELD score.
- To determine if MELD score is an independent predictor of adverse outcomes following pancreatectomy.
Main Methods:
- Analysis of the 2014-2016 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Procedure Targeted Pancreatectomy Data.
- Comparison of outcomes (mortality, complications, length of stay, discharge disposition, transfusion) between patients with MELD scores <11 and ≥11.
- Multivariable logistic regression was used to assess the risk-adjusted impact of MELD score on outcomes.
Main Results:
- Patients undergoing pancreatoduodenectomy (PD) with MELD ≥11 had higher risks of mortality (OR=2.07), discharge not-to-home (OR=1.26), and transfusion (OR=1.7).
- Patients undergoing distal pancreatectomy (DP) with MELD ≥11 experienced prolonged length of stay (OR=1.75), discharge not-to-home (OR=1.83), and transfusion (OR=2.78).
- MELD ≥11 independently predicted 30-day mortality and transfusion in PD, and prolonged LOS and transfusion in DP.
Conclusions:
- A MELD score of 11 or higher is associated with a nearly twofold increase in mortality risk after pancreatoduodenectomy.
- The MELD score serves as an objective tool for risk stratification in patients undergoing pancreatectomy.
