Optimal Procedural Sequence in Same-day Bidirectional Endoscopy: A Prospective Randomized Controlled Study

December 4, 2016 updated by: Chi-Liang Cheng, Evergreen General Hospital, Taiwan

Optimal Procedural Sequence in Same-day Bidirectional Endoscopy With Moderate Sedation and Carbon Dioxide Insufflation: A Prospective Randomized Controlled Study

The Same-day bidirectional endoscopy (BDE) is commonly used in clinical practice. However, the optimal sequence of performing a same-day BDE has not been well-established.The primary aims of this study are to compare the sedative doses and patient discomfort between the study groups who received a colonoscopy followed by and EGD (colonoscopy-EGD), or an EGD followed by a colonoscopy (EGD-colonoscopy) during a same-day BDE. The secondary aim is to assess colonoscopy performance, including the cecal intubation time and adenoma detection rate between the two endoscopic sequences.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

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

16 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

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.
Active Comparator: EGD-colonoscopy group
In this group, patients receiving an EGD followed by a colonoscopy during a same-day bidirectional endoscopy. Patients receive moderate conscious sedation with fentanyl and midazolam for the procedures. Gastric polypectomy will be provided when gastric polyps are found during an EGD study. Colon polypectomy will be provided when colon polyps are found during a colonoscopy study. Patients' heart rate, respiratory rate, blood pressure, and oxygen saturation will be recorded every 60 seconds during the endoscopic examinations. Patients' tolerability to EGD and colonoscopy examinations will be scaled by patients and endoscopists after the completion of the examinations. Aldrete scores are recorded15 minutes and 25 minutes after entering the recovery room. The recovery time will also be recorded.
Procedure: EGD and colonoscopy
Cold forceps biopsy, cold snare polypectomy, and/or hot snare polypectomy will be performed for stomach and/or colon polyps during EGD and colonoscopy examinations will be performed whenever indicated.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sedative Doses of Fentanyl
Time Frame: On the day of endoscopic procedures.
During bidirectional endoscopy, the total doses of fentanyl were recorded and compared between the two study groups.
On the day of endoscopic procedures.
Sedative Doses of Midazolam
Time Frame: On the day of bidirectional endoscopy procedures
During bidirectional endoscopy, the total doses of midazolam were recorded and compared between the two study groups.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
