Abstract

TORO-CALLE, Jerónimo; GUZMAN-ARANGO, Carolina; RAMIREZ-CEBALLOS, Mariana  and  GUZMAN-ARANGO, Natalia. Are the ASGE criteria sufficient to stratify the risk of choledocholithiasis?. Rev Col Gastroenterol [online]. 2020, vol.35, n.3, pp.304-310.  Epub Mar 01, 2021. ISSN 0120-9957.  https://doi.org/10.22516/25007440.464.

Introduction:

Biliary lithiasis is one of the most frequent diseases in the area of general surgery and gastroenterology. Treatment varies depending on the location of the gallstones. Several stratification scales of the risk of choledocholithiasis have been defined, being the criteria proposed by the American Society of Gastrointestinal Endoscopy (ASGE) the most used worldwide, with a diagnostic accuracy of 70%. However, the procedures or diagnostic aids defined by these criteria, sometimes, increase hospital stay, costs, and may lead to the development of complications.

Methodology:

An observational, analytical, retrospective, cross-sectional study was conducted with data obtained from the clinical records of patients undergoing laparoscopic cholecystectomy at the CES Clinic in Medellín, Colombia, between July and December of 2017.

Results and conclusions:

424 medical records were analyzed, of which 254 (56.76%) were classified as low-risk, 94 (22.11%) as intermediate-risk and 76 (17.88%) as high-risk. The frequency of choledocholithiasis was 90.8% in high-risk patients and 26.6% in intermediate-risk patients. For the intermediate-risk category, statistically significant differences were found between the two groups for the total bilirubin, direct bilirubin, and AST values (p: 0.001, p: 0.014, p:0.007, respectively). The low frequency of choledocholithiasis in the intermediate-risk category can be explained by less than 5mm gallstones not identified by the cholangioresonance. Based on this study, we propose to adjust the ranges of the ASGE criteria variables for the intermediate-risk category for better accuracy when classifying patients with biliary lithiasis and, thus, reduce costs and hospital stay.
