Abstract

Insights

A higher Model End-Stage Liver Disease (MELD) score (≥11) significantly increases the risk of 30-day complications and mortality after gastrectomy surgery. Patients with MELD scores below 11 experienced better outcomes.

Area of Science:

  • Surgical Oncology
  • Gastroenterology
  • Medical Informatics

Background:

  • The Model End-Stage Liver Disease (MELD) score is a validated tool for predicting patient outcomes in various surgical contexts.
  • Gastrectomy, a major surgical procedure for stomach conditions, carries inherent risks that necessitate accurate preoperative risk assessment.

Purpose of the Study:

  • To evaluate the association between preoperative Model End-Stage Liver Disease (MELD) scores and adverse 30-day postoperative outcomes in patients undergoing gastrectomy.
  • To determine if elevated MELD scores predict increased complication rates and mortality post-gastrectomy.

Main Methods:

  • Analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database from 2014 to 2019.
  • Inclusion of patients who underwent elective, non-emergent gastrectomy, categorized by their calculated MELD score.
  • Assessment of 30-day overall and major complication rates as primary outcomes.

Main Results:

  • Patients with a MELD score of 11 or higher demonstrated significantly higher rates of mortality, overall complications, and major complications compared to those with MELD <11.
  • Multivariate analysis confirmed that a MELD score ≥11 was independently associated with increased odds of any complication (OR 1.73) and major complications (OR 1.85).

Conclusions:

  • A preoperative MELD score of 11 or greater is a significant predictor of adverse outcomes following gastrectomy.
  • Elevated MELD scores indicate a higher risk profile, guiding preoperative risk stratification and patient counseling for gastrectomy.
