Early Intervention for Morbidly Obese Patients After Roux-en-Y Gastric Bypass (RYGB) Surgery (Back on Track)

February 7, 2012 updated by: Duke University

Early Intervention in Patients With Predicted Poor Long-term Outcome Following Laparoscopic Roux-en-Y Gastric Bypass: a Prospective Randomized Study

Purpose and objective: To identify in the early post-operative period following laparoscopic Roux-en-Y gastric bypass patients likely to fail to progressively lose weight in expected fashion, and to institute intervention and assess for its efficacy.

Study activities and population group: Patients identified to have "poor weight loss" (≤ 11% of excess weight loss) at 1 month will be randomized into a control versus study group. Intervention for subjects randomized to the IV arm will be by enrollment in the Back on Track program. This is a seven-week group education, counseling, nutrition, exercise, and journaling program of the Duke Weight Loss Surgery Center designed to help postoperative bariatric surgery patients who are failing to progressively lose weight resume an expected pattern of weight loss and improved overall outcome.

Data analysis and risk/safety: Data will be collected and analyzed by the identified investigators. The goal of data analysis is to uncover any difference in the EWL of subjects who underwent intervention for falling in the lowest EWL quartile when compared with those who did not undergo intervention, and determine the statistical significance of any such difference. There are no physical risks associated with this study. There is, however, the potential risk of loss of confidentiality. Every effort will be made to keep your information confidential.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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: Lifestyle counseling

This is a seven-week group education, counseling, nutrition, exercise, and journaling program of the Duke Metabolic and Weight Loss Surgery Center designed to help postoperative bariatric surgery patients who are failing to progressively lose weight resume an expected pattern of weight loss and improved overall outcome.

Weeks 1 and 2 consist primarily of a review of current dietary habits. Weeks 3, 4, & 5 introduces counseling, with specific emphasis on emotional aspects of eating and behavioral modification strategies. Week 6 focuses on the metabolic impact of exercise, and includes an exercise session with a personal trainer. Week 7 incorporates a question and answer session with a sharing of discoveries, as well as an option for additional individual follow-up as needed.
Behavioral: Lifestyle counseling
Weeks 1 and 2 consist primarily of a review of current dietary habits with initiation of a food journal; a basic review of macronutrients and metabolism; and the beginning of a weekly exercise regimen. Weeks 3, 4, & 5 introduces counseling, with specific emphasis on emotional aspects of eating and behavioral modification strategies. Week 6 focuses on the metabolic impact of exercise, and includes an exercise session with a personal trainer. Week 7 incorporates a question and answer session with a sharing of discoveries, as well as an option for additional individual follow-up as needed. During this period, patients will also be given access to an interactive web-based tool providing additional emphasis on the aforementioned components and clinician follow-up.
No Intervention: RYGB regular post-op care
Regular care and follow-up after RYGB surgery

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.
