Rate of Duodenal-biliary Reflux Increases in Patients With Recurrent Common Bile Duct Stones
December 1, 2015 updated by: Yanglin Pan, Air Force Military Medical University, China
Rate of Duodenal-biliary Reflux Increases in Patients With Recurrent Common Bile Duct Stones: Direct Evidence From Barium Meal Examination
ERCP is the primary choice for removal of common bile duct stone (CBDS) currently.
However, 4-24% patients underwent recurrence after successful clearance of CBDS.
Stone re-formation due to chronic inflammation of biliary duct is generally considered an important cause of CBDS recurrence, which is associated with duodenal-biliary reflux (DBR) after sphincterotomy.
Although it was believed that DBR was the important cause of CBDS recurrence, the direct evidence was still lacking.
Here we conducted a case control study to investigate the DBR rate in patients with recurrent CBDS after ERCP.

Study Population
Patients with history of recurrent common bile duct stone (recurrent group) and non-recurrent common bile duct stone (control group) in Xijing Hospital of Digestive Diseases were invited to participate the study.
All the patients underwent successful stone removal by ERCP previously.
Patients in the control group were matched with the recurrence group by age and gender at 1:1 ratio.
Description
Inclusion Criteria:
- Patients with common bile duct stone underwent successful stone removal by ERCP in Xijing Hospital of Digestive Diseases.
Exclusion Criteria:
- Gallbladder stones or hepatolithiasis;
- Stenosis of biliary duct;
- Incomplete common bile duct stone removal by ERCP;
- Common bile duct stent;
- Unable to provide informed consent.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Recurrent group
Patients with history of recurrent common bile duct stone after successfully ERCP stone remove.
|
All eligible patients received standard barium meal examination, MRCP and enhanced abdominal CT.

Control group
Patients without history of recurrent common bile duct stone after successfully ERCP stone remove.
|
All eligible patients received standard barium meal examination, MRCP and enhanced abdominal CT.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Duodenal-biliary reflux rate
Time Frame: up to 6 months
|
The proportion of patients with barium reflux into bile duct during the standard barium meal examination.
|
up to 6 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Distal common bile duct angle
Time Frame: up to 6 months
|
MRCP revealed the first angulation from the ampullary orifice along the course of the common bile duct stone.
|
up to 6 months
|
Maximal CBD diameter
Time Frame: up to 6 months
|
Maximal CBD diameter was determined by MRCP.
|
up to 6 months
|
Peripapillary diverticulum
Time Frame: up to 6 months
|
Peripapillary diverticulum was defined endoscopically as the presence of a diverticulum within a 2-cm radius from the papilla and was divided into 2 types in terms of the relation between the papilla and diverticulum: type A, papilla located on the inner rim of the diverticulum or papilla located deep within the diverticulum; and type B, papilla located outside the diverticulum.
|
up to 6 months
|
Pneumobilia
Time Frame: up to 6 months
|
Pneumobilia were determined by CT
|
up to 6 months
