Predicting liver repair in hepatitis B after treatment
This study looks at whether non-invasive tests can tell if liver damage is reversing in people with hepatitis B who have been on antiviral therapy for at least a year. It aims to help avoid repeated liver biopsies.
BeijingAges 18 years+ - NCT04523701RecruitingPhase 3
Testing a “white test” to find bile ducts during liver surgery
This trial studies whether a simple “white test” using a special lipid (fat-like) solution can help the surgical team spot open bile ducts early during liver removal. Finding them sooner may help prevent bile leakage after liver surgery.

Endoscopic treatment for certain superficial stomach growths
This trial studies how safe and effective a procedure called endoscopic submucosal dissection (ESD) is for treating certain early, superficial stomach (gastric) growths. It may be an option if your growth fits the endoscopy criteria and you are not a good candidate for stomach surgery.
