Plain English summary of protocol

Background and study aims
Even though it's common for certain gallstone problems not to cause jaundice (yellowing of the skin), we don't fully understand why. People often think it's because the bile duct isn't completely blocked. This seems reasonable, but it doesn't explain everything.

This study looked at how bile (a digestive fluid) moves in these cases, using special scans called magnetic resonance cholangiopancreatography and selective intraoperative cholangiography before and during surgery to figure this out.

This study will give us a better overall view of how bile flows, helping us understand why jaundice might not happen in gallstone cases. It also helps doctors decide on the best treatment.

Who can participate?
Patients with anicteric choledocholithiasis admitted to the Department of Hepatobiliary Surgery of Hainan General Hospital from January 2019 to July 2023.

What does the study involve?
Preoperative magnetic resonance cholangiopancreatography and intraoperative cholangiography were performed to determine the direction of bile flow in all patients.

What are the possible benefits and risks of participating?
None

Where is the study run from?
Hainan General Hospital (China)

When is the study starting and how long is it expected to run for?
June 2019 to July 2023

Who is funding the study?
Hainan Provincial Department of Science and Technology (China)

Study typeDiagnostic, Treatment
Participant information sheet No participant information sheet available (retrospective study)
Scientific titleClassification and treatment of anicteric choledocholithiasis based on the patterns of bile flow into the duodenum
Study objectivesThe absence of jaundice in these patients may be due to the passage of bile into the duodenum through a specific path.
Ethics approval(s)

Approved 20/12/2018, The medical ethics committee of Hainan general hospital (No.19 Xiuhua road, Xiuying district, Haikou, 570311, China; +86 898-68622476; meng@hnsrmyy14.wecom.work), ref: Med-Eth-Re[2018] 81

Health condition(s) or problem(s) studiedCholedocholithiasis
InterventionCurrent interventions as of 19/01/2024:

Patients with anicteric choledocholithiasis were admitted to the Department of Hepatobiliary Surgery of Hainan General Hospital from January 2019 to July 2023. Preoperative magnetic resonance cholangiopancreatography (MRCP) and intraoperative cholangiography (IOC) were performed to determine the direction of bile flow in all patients.
