About this study

Official title: A Prospective Study of Treating Duodenal Papillary Sphincter in Different Ways During ERCP: Comparison of EST, EPBD, and sEST+EPBD in Endoscopic Choledocholithiasis Treatment.

Endoscopic retrograde cholangiopancreatography (ERCP) is commonly performed to remove bile duct stones.Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilation (EPBD), and endoscopic sphincterotomy plus balloon dilation (sEST+EPBD) are 3 methods used to enlarge the papillary orifice, but their efficacy and safety remains controversial. This study aimed to compare these methods for treating common bile duct (CBD) stones.

Read the detailed description

Investigators first divided the patients with different sizes of common bile duct stones into two groups. The bile duct stone diameter of group A is less than 1.0cm while group B is more than 1.0cm and less than 1.5cm. Each group compared Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilation (EPBD), and endoscopic sphincterotomy plus balloon dilation (sEST+EPBD) in ERCP. Through the postoperative comparison of relevant inspection test indicators, the recovery of patients, whether the occurrence of complications, including infection,bleeding,pancreatitis,perforation , and 1 year stone recurrence rate,Investigators assess the advantages and disadvantages in three different strategies in different sizes of common bile duct stones , and finally get a relatively objective evaluation to guide our daily ERCP work on the choice of duodenal papillary sphincter treatment strategy.

Study groups in NCT03416205
Study groupRoleWhat they receive
ESTExperimentalEST is an operation using the Erbao electric knife and Three-cavity incision knife to make a large incision to the duodenal nipples,and the incision scope is the nipple mouth uplift length of 4/5. It has been used since 1974. The technique is intuitive and intact. However, EST cut too small to achieve the purpose of treatment and will affect the next step, and if the incision is too large it may be easier to occur gastrointestinal perforation and bleeding.The EST will also damage the anatomy of the Oddi sphincter structure,which causes bacterial reflux to the bile duct, the recurrence of CBD.Some surgeons prefer it because it's postoperative pancreatitis rate is lower and it may be easier to find the lesion position if bleeding or perforation occurs.
Receives: Device: Erbao electric knife; Device: Three-cavity incision knife
EPBDExperimentalEPBD is an operation using the Columnar expansion balloon to expand duodenal to achieve the purpose of using the basket and other instruments to take stone out. Balloon expansion may retain part of the sphincter not destroyed, and basically retain the normal physiological function of the nipple sphincter.Thus it may reduce the risk of recurrence of stones and bacterial reflux. However,the postoperative pancreatitis rate is high(4.8% -19.5% ), and nipple sphincter tear is uncontrollable in EPBD.If the digestive tract perforation or bleeding occur after EPBD,it is hard to accurately find the lesion position.Some surgeons prefer it for it's lower bleeding and perforation rate.
Receives: Device: Columnar expansion balloon
sEST+EPBDExperimentalsEST+EPBD is an operation combining EST and EPBD. Investigators use the Erbao electric knife and Three-cavity incision knife to make a small incision to the duodenal nipples, and the incision length is less than 5mm while the incision scope is less than the nipple mouth uplift length of 1/2. Then, Investigators match the appropriate Columnar expansion balloon according to the diameter of the common bile duct and gradually expand the duodenal nipples.This method allows the nipple sphincter to be cut in a small range, then the balloon can guide the direction of the nipple sphincter tearing after the expansion , so that the digestive tract bleeding, perforation may be smaller and more controllable. Besides,it may reduce postoperative pancreatitis rate and the recurrence rate of stones.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the incidence of composite events of infection, hemorrhage, perforation, pancreatitis

    Investigators comprehensively assess whether the hemorrhage, perforation, pancreatitis and other complications of retrograde cholangiopancreatography (ERCP) happen or not by clinical sympton and blood index 1 day after the ERCP. The blood index includes CRP, amylase,lipase,leukocyte,red blood cell,hemoglobin.Besides,CT will be done if necessary.Finally investigators use statistical method to analyse the incidence of composite events of infection, hemorrhage, perforation, pancreatitis.

    Measured: 3 and 24 hours after the ERCP

Secondary outcomes (1)
  1. Recurrence rate of bile duct stones

    One year after the ERCP,the participants will have a CT scan to find out whether the bile duct stones recur again.

    Measured: 1 year after the ERCP.

Questions about this trial

What is this clinical trial studying?

A study testing Erbao electric knife, Three-cavity incision knife and Columnar expansion balloon in people with ERCP, run by Zhujiang Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the incidence of composite events of infection, hemorrhage, perforation, pancreatitis (time frame: 3 and 24 hours after the ERCP). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
