Objectives: To develop a radiomics algorithm, improving the performance of detecting recurrence, based on posttreatment CT images within one month and at suspicious time during follow-up.
Materials And Methods: A total of 114 patients with 228 images were randomly split (7:3) into training and validation cohort. Radiomics algorithm was trained using machine learning, based on difference-in-difference (DD) features extracted from tumor and liver regions of interest on posttreatment CTs within one month after resection or ablation and when suspected recurrent lesion was observed but cannot be confirmed as HCC during follow-up.
Article Synopsis
- Endoscopic sphincterotomy (EST) is a less invasive method for treating common bile duct stones (CBDS), but concerns exist over its complications and recurrence rates compared to open choledochotomy (OCT).
- This study aimed to compare the effectiveness of EST and OCT and identify risk factors for stone recurrence by analyzing the outcomes of 302 patients over a follow-up period of at least five years.
- Results showed EST required less time for procedure and recovery, had a higher complete stone clearance rate, but similar rates of complications and mortality compared to OCT; recurrence of CBDS occurred in 18.8% of patients.
