# GBDKVA score: a scoring system for preoperative risk assessment of adrenal tumors ≤6cm

## TL;DR

This study introduces a new scoring system, GBDKVA, to assess surgical risk for small adrenal tumors and validates its effectiveness.

## Contribution

The novel GBDKVA scoring system combines six preoperative factors to evaluate surgical risk for adrenal tumors ≤6cm.

## Key findings

- GBDKVA score correlated significantly with operation time and blood loss (p < 0.01).
- The score was also associated with postoperative complications but not with recovery time or hospitalization duration.
- The system proved reliable for preoperative risk assessment of adrenal tumors ≤6cm.

## Abstract

To propose a comprehensive scoring system for adrenal tumors ≤ 6cm and evaluate its rationality and validity.

This study retrospectively analyzed 268 patients with primary adrenal tumors who underwent laparoscopic surgery from January 2018 to December 2022 and all of them met the inclusion criteria. Evaluation scores were calculated for gender (G), body mass index (BMI) (B), tumor diameter (D), the relative position of the tumor to the kidney (K), the relative position of the tumor and the blood vessels (V) and the tumor location in the adrenal gland (A). Then, the total scores were correlated with the operation results, so as to verify the feasibility of GBDKVA in evaluating the surgical risk.

The GBDKVA score showed a consistent and statistically significant correlation with operation time (OT) and blood loss (BL), as well as a correlation with postoperative complications in patients (p < 0.01), but no significant correlation was found with recovery time of gastrointestinal function, bed rest days, indwelling drainage tube days and postoperative hospitalization time were opposite.

GBDKVA score is reliable for preoperative risk assessment of patients with adrenal tumors ≤6cm.
