Usefulness of simplified comprehensive geriatric assessment as a pre-ERCP screening for the elderly.

Abstract

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is often performed in elderly patients for stone removal and biliary drainage following common bile duct stones or malignant biliary obstruction. Safety in ERCP should be considered in elderly patients due to complications and decreased activities of daily living (ADL), but there are no adequate pretest evaluation criteria. In recent years, the usefulness of the comprehensive geriatric assessment (CGA) for planning treatment and predicting prognosis has been reported.

Methods: We retrospectively analyzed consecutive patients who underwent ERCP at our institution between October 2021 and June 2023. The relationship between CGA and ERCP outcomes was examined by dividing CGA scores into three groups (Group A; score 0, Group B; score 1-4, Group C; score 5-7) among patients 65 years of age and older. Risk factors for prolonged hospitalization were identified using univariate and multivariate analysis.

Results: Of the 388 patients, 290 were 65 or older with a CGA score. The median length of hospital stay was significantly longer in the higher CGA7 scores group (5 vs. 8 vs. 15 days, p < .01). There was no significant difference in the rate of adverse events (p = .54) and median total procedure time (p = .35). In univariate and multivariate analysis, higher CGA score groups were significant risk factors for a prolonged hospital stay.

Conclusions: CGA appears to be a valuable tool for preadmission screening in elderly patients undergoing ERCP.
