About this study

Official title: The Efficacy and Safety of Precut Papillotomy Using the Knob-tipped Knife and Needle Knife in Difficult Biliary Cannulation: a Randomized-controlled Trial.

The aim of the present study was to compare the efficacy and safety of the knob-tipped knife and needle knife for precut papillotomy in difficult common bile duct (CBD)cannulation.

Read the detailed description

Precut sphincterotomy is an alternative technique used to facilitate CBD cannulation following the failure of conventional bile duct cannulation. Needle knife papillotomy is the most widely practiced precut technique. However,Pre-cutting the papilla with a needle-knife is difficult, requiring experience and dexterity to control the axis and depth of the cut. Due to the increased rate of complications associated with this procedure, including pancreatitis, hemorrhage, and perforation, it was recommended to be performed only by experienced endoscopists.

The knob-tipped knife, a novel instrument utilizing a 2mm or 1.5mm cutting knife, is usually used for endoscopic submucosal dissection (ESD). Its knob-shaped tip and nonadjustable length make the knife less likely to slip and penetrate the tissue during the resection. Since the process of precut papillotomy is similar to ESD, the precutting procedure with the knob-tipped knife may be easier to be performed, as well as be safer. The efficacy and safety of this instrument in precut papillotomy have not been reported. We therefore assessed the efficacy and safety of the knob-tipped knife in precut papillotomy in difficult CBD cannulation.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Precut papillotomy in people with Endoscopic Retrograde Cholangiopancreatography and Bile Duct Diseases, run by Changhai 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 2 inclusion and 4 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 10 Dec 2012. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact zhaoshen Li, MD (86-21-81873241, zhaoshenlismmu@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Successful biliary cannulation rate after precut papillotomy (time frame: During endoscopic retrograde cholangiopancreatography (ERCP) procedure). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2012.
