Insights
The red cell distribution width-to-albumin ratio (RAR) effectively predicts major complications and mortality in peptic ulcer perforation patients. This marker shows high accuracy, aiding clinical risk assessment.
Area of Science:
- Gastroenterology
- Surgical Outcomes
- Biomarker Research
Background:
- Peptic ulcer perforation is a severe complication of peptic ulcer disease.
- Existing scoring systems have limitations in predicting patient outcomes.
- The prognostic value of the red cell distribution width-to-albumin ratio (RAR) in this context is not well-established.
Purpose of the Study:
- To investigate the predictive value of the red cell distribution width-to-albumin ratio (RAR) for outcomes in patients with peptic ulcer perforation.
- To assess RAR's ability to predict major postoperative complications and 30-day mortality.
Main Methods:
- A retrospective study of 187 patients who underwent surgery for peptic ulcer perforation (2016-2024).
- Analysis of patient demographics, clinical data, laboratory values, and surgical outcomes.
- Multivariate regression and receiver operating characteristic (ROC) curve analysis to identify predictors and assess diagnostic accuracy.
Main Results:
- Major complications occurred in 18.1% and 30-day mortality was 9.6%.
- Age, surgical delay, elevated C-reactive protein, and RAR were independent predictors of major complications.
- Age and RAR were significant independent predictors of 30-day mortality.
- RAR demonstrated high diagnostic accuracy for predicting both major complications (AUC=0.883) and mortality (AUC=0.944).
Conclusions:
- The red cell distribution width-to-albumin ratio (RAR) is a sensitive and specific prognostic marker for peptic ulcer perforation.
- RAR has significant potential for clinical use in conjunction with traditional risk factors to predict outcomes.
- Incorporating RAR may improve risk stratification and patient management in peptic ulcer perforation.
Background:
Peptic ulcer perforation is a potentially life-threatening complication of peptic ulcer disease. Several scoring systems have been developed to predict outcomes in these patients. The red cell distribution width-to-albumin ratio (RAR) has shown promise as a prognostic marker in various conditions, yet its role in peptic ulcer perforation remains unclear. This study aimed to evaluate the predictive value of RAR in patients with peptic ulcer perforation.
Methods:
This retrospective study was conducted between 2016 and 2024 on patients who underwent surgery for peptic ulcer perforation. Patient demographics, clinical features, laboratory values, and surgical outcomes were analyzed. The main outcomes were major postoperative complications and 30-day mortality. Multivariate regression analysis was used to identify independent predictors of these outcomes. The ability of RAR to predict outcomes was also assessed.
Results:
The study included 187 patients with a median age of 49.7 years, of whom 78.6% were males. Major complications occurred in 18.1% of the patients and the 30-day mortality rate was 9.6%. Multivariate analysis identified age, surgical delay, elevated C-reactive protein and RAR as independent predictors of major complications. For 30-day mortality, only age and RAR remained significant in the multivariate model. Receiver operating characteristic curve analysis showed that RAR had high diagnostic accuracy for predicting both major complications (AUC = 0.883) and mortality (AUC = 0.944).
Conclusion:
With its high sensitivity and specificity for predicting major complications and mortality in patients with peptic ulcer perforation, RAR has significant potential as a prognostic marker in conjunction with traditional risk factors in clinical practice.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
