Research and development of artificial biliary substitutes is an indispensable part of modern biliary surgery, bearing great clinical significance on the recovery of the normal functions of the biliary system. The implantation of artificial biliary substitutes may cause the blockage or stenosis of the biliary duct at the transplantation site, which is the most urgent problem in the research of artificial biliary substitutes. The fundamental cause of the problem is tissue hyperplasia caused by chronic inflammatory stimulation of artificial biliary substitutes. The regeneration of new bile duct tissue at the transplantation site can provide a solution to this problem. By looking at the literature from China and abroad, this paper reviewed the research and development of non-degradable artificial bile duct, degradable artificial bile duct and tissue-engineered artificial bile duct in order to provide reference for the further development of biliary replacements. Future studies should focus on the rapid formation of biliary epithelial layer on the tissue-engineered artificial biliary wall, the promotion of new biliary tissue formation, and the regulation of the degradation performance and mechanical properties of artificial biliary duct in order to fundamentally solve the problems encountered in the research of artificial biliary substitutes and accelerate the development of artificial biliary duct.

The biliary system is crucial for liver function, regulating bile production, secretion, and transport. Dysfunctions within this system can lead to various diseases, such as cholangiopathies and biliary fibrosis, which may progress from benign to malignant states like cholangiocarcinoma. While liver organoid research is well-established and technologically advanced, bile duct organoids (BDOs) offer significant potential.

Gallbladder cancer (GBC) frequently mimics gallbladder benign lesions (GBBLs) in radiological images, leading to preoperative misdiagnoses. To address this challenge, we initiated a prospective, multicenter clinical trial (ChicCTR2100049249) and proposed a multimodal, non-invasive diagnostic model to distinguish GBC from GBBLs. A total of 301 patients diagnosed with gallbladder-occupying lesions (GBOLs) from 11 medical centers across 7 provinces in China were enrolled and divided into a discovery cohort and an independent external validation cohort.

Background: Mild acute biliary pancreatitis (MABP) presents significant clinical and economic challenges due to its potential for relapse. Current guidelines advocate for early cholecystectomy (EC) during the same hospital admission to prevent recurrent acute pancreatitis (RAP). Despite these recommendations, implementation in clinical practice varies, highlighting the need for reliable and accessible predictive tools.
