Trial summary

Because the ampulla of Vater is strategically located at the confluence of the pancreatic and common bile ducts, endoscopic resection of papillary neoplasms may be technically different from endoscopic mucosal resection in other parts of the gastrointestinal tract. Read more about this study

About this study

Official title: A Prospective Comparative Study of Papillectomy

Because the ampulla of Vater is strategically located at the confluence of the pancreatic and common bile ducts, endoscopic resection of papillary neoplasms may be technically different from endoscopic mucosal resection in other parts of the gastrointestinal tract. The best method of endoscopic ablation and the optimal period for surveillance have not been established.

Read the detailed description

While some endoscopists advocate the use of submucosal injection of either physiologic saline solution or dilute epinephrine, some do not. Whether physiologic saline solution or dilute epinephrine should be used is also not established. Submucosal injection of either dilute epinephrine or saline solution may be useful for avoiding inappropriate resection because failure to lift the tumor from the proper muscle layer of the duodenum may indicate deeper invasion18 and is the strongest predictor of malignancy.

In adenomas of the major duodenal papilla, however, some investigators do not recommend submucosal injection. Not only the surrounding mucosa at the region of the duodenal papilla but also the tumor is lifted by submucosal injection, so capturing the lesion with a snare becomes difficult.

    Conventional endoscopic mucosal resection of ampulla of Vater using a snare with electrocurrent.

  • Papillectomy with injectionProcedure or surgery

    Conventional endoscopic mucosal resection of ampulla of Vater without submucosal saline or diluted epinephrine injection.

What is being measured

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

  1. complete resection

    Following endoscopic papillectomy, complete resection will be estimated by pathologic examination

    Measured: one month

Secondary outcomes (1)
  1. complication

    Immediate complications after papillecotmy Delayed complications during 24 hours

    Measured: within 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Papillectomy without injection and Papillectomy with injection in people with Ampulla of Vater Adenoma, run by Soon Chun Hyang University at 1 site in South Korea.

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 3 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: finished, as of the sponsor's last update on 15 Oct 2015. 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 South Korea. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

complete resection (time frame: one month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02165852, which also lists 1 linked publication.

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 15 Oct 2015.
