Comparison of Off-site vs. hands-on Assistance for Trainees During ERCP: a Randomized, Controlled, Noninferiority Study

Endoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure. It takes time to learn the basic skill and at least 180 - 200 cases for trainees to achieve competency in ERCP. Hands-on practice in patients remains the gold standard for ERCP training. It required the trainer to stand by the trainee in the procedure room to assist. There were insufficient patients for most trainees to achieve competence until the trainee graduate. Technology-enabled health care at a distance has profound scientific potential and accordingly has been met with growing interest. We hypothesized that the trainee can be safely guided by a senior trainer off-site with the endoscopic view displayed on a screen. Using the teleguidance, the trainer can even continue to provide guidance when the trainees complete their training and return to their hospitals until they achieve the recommended clinical competency. Given the advantages of the off-site teleguidance, it could be an attractive substitute for hands-on assistance to ERCP training.

The primary aim of this study was to evaluate whether off-site assistance (OA group) could achieve a comparable success rate to standard hands-on assistance (HA group) with regard to the rates of successful selective biliary cannulation during ERCP training.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Patients aged 18-90 years who received ERCP
  2. Patients with native papilla

Exclusion Criteria:

  1. Patients with altered anatomy (Billroth I/II, Roux-en-Y)
  2. Type II duodenal stenosis
  3. Previously failed cannulation

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Off-site assistance group
The trainer supervised the trainee's cannulation operation outside the procedure room through a high-definition screen displaying the endoscopic view. Trainees wear headphones, and trainers use intercom to provide the unlimited verbal instructions. The trainer was not allowed into the procedure room and touched the endoscope or accessories until the trainee ask for help or failed to achieve deep biliary cannulation. Then the trainer would then take over and continue with the cannulation. The trainer would halt and correct the trainee's inappropriate maneuvers immediately to avoid unnecessary papillary trauma and potential complications.
Behavioral: The assistance type during ERCP
The senior trainer guides the trainees during ERCP procedure outside the operating room using communication equipment and the screen displaying an endoscopic view.
Active Comparator: Hands-on assistance group
During trainees' attempted cannulation, the trainer gave unlimited verbal instructions with hands-on assistance limited to only adjustment of scope position if necessary. To avoid unintended cannulation, the trainer was not allowed to touch the control section of the scope or the sphincterotome used for cannulation. However, the trainer would correct any inappropriate maneuvers immediately to avoid unnecessary papillary trauma and potential complications. The trainees could ask for help or stop cannulation at any time if they were not comfortable continuing the procedure. The trainer would then take over and continue with the cannulation.
Behavioral: The assistance type during ERCP
The senior trainer guides the trainees during ERCP procedure outside the operating room using communication equipment and the screen displaying an endoscopic view.
