Study Overview

Status

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

14 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  3. Able to provide consent

Exclusion criteria:

  1. History of anti-reflux procedure
  2. History of foregut surgery

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: Crura Dissection
Participants with a visually detectable hiatal hernia at the time of sleeve gastrectomy procedure will undergo a crura dissection and hiatal hernia repair.
Procedure: Crura dissection
The diaphragmatic crura, one of two tendon structures below the diaphragm, will be removed during the laparoscopic sleeve gastrectomy.
Procedure: Sleeve gastrectomy
Surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature.
Procedure: Hiatal hernia repair
This involves tightening the opening in your diaphragm with stitches to keep your stomach from bulging upward through the opening in the muscle wall.
Experimental: National Practice
Participants with no detectable hiatal hernia will be randomized to either Group 2 or 3. Group 2 participants will be treated to the national practice patterns of complete dissection of the curvature of the stomach without dissection of the crura.
Procedure: Sleeve gastrectomy
Surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature.
Experimental: Standard of Care
Participants with no detectable hiatal hernia will be randomized to either Group 2 or 3. Group 3 participants will undergo the institutional standard of care with the dissection of the crura.
Procedure: Crura dissection
The diaphragmatic crura, one of two tendon structures below the diaphragm, will be removed during the laparoscopic sleeve gastrectomy.
Procedure: Sleeve gastrectomy
Surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature.

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
Change in Perioperative Symptoms as assessed by the Intermediate and Late-Post Operative Pain, Nausea and Dysphagia Questionnaire
Time Frame: Day 1, 12 months
The Intermediate and Late Post-Operative Pain, Nausea and Dysphagia Questionnaire is a 7-item questionnaire with scores ranging 0-40 with the higher score indicating severe symptoms.
Day 1, 12 months
Change in Perioperative Symptoms as assessed by the Rhodes Index of Nausea, Vomiting and Retching Questionnaire
Time Frame: Day 1, 12 months
The Rhodes Index of Nausea, Vomiting and Retching Questionnaire is an 8-item questionnaire with scores ranging from 0 to 32 with a higher score indicating increased symptoms of nausea.
Day 1, 12 months
Change in Perioperative Symptoms as assessed by the Gastroesophageal Reflux Disease-Questionnaire (GERD-Q)
Time Frame: Baseline, 12 months
The GERD-Q has a scoring range between 0-18 with a higher score indicating increased likelihood of GERD.
Baseline, 12 months
Change in Perioperative Symptoms as assessed by the Brief Esophageal Dysphagia Questionnaire (BEDQ)
Time Frame: Baseline, 12 months
The BEDQ has a scoring range between 0-40 with a higher score indicating increased symptoms of dysphagia.
Baseline, 12 months

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.
Outcome Measure
Measure Description
Time Frame
Correlation of the presence of hiatal hernias
Time Frame: Day 1
Correlation of the presence of hiatal hernias between pre-operative upper Gastrointestinal (GI) series and surgical findings.
Day 1

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
