To examine the performance of indexed and non-indexed eGFR using creatinine levels and assess the impact of GFR changes on mortality and other clinical outcomes in patients undergoing biliopancreatic diversion.
Key Findings:
The CKD-EPI formula non-indexed was found to be the most appropriate for estimating GFR in this population, suggesting its use in clinical settings.
Patients with higher BMI had lower average eGFR values, indicating a potential risk factor for adverse outcomes.
No substantial differences in clinical characteristics were observed across baseline GFR tertiles, which may inform patient stratification.
Interpretation:
Accurate GFR assessment is crucial for evaluating surgical risk and long-term outcomes in bariatric surgery patients, particularly given the challenges posed by obesity-related changes in kidney function, which can complicate postoperative recovery.
Limitations:
The study's retrospective design may introduce biases.
The equations used for GFR estimation were developed from populations with lower obesity prevalence, potentially affecting their accuracy.
Sample size may limit the generalizability of the findings.
Conclusion:
The study highlights the importance of using appropriate GFR estimation methods in bariatric surgery patients to better understand their mortality risk and kidney health, emphasizing the need for tailored approaches in clinical practice.
A four-factor staging system stratified response rates from 90.9% to 37.5% in a retrospective cohort study, although the model showed only moderate discrimination (C statistic, 0.68) and requires external validation
