Gastric Emptying After Sleeve Gastrectomy (EMRISS)

March 30, 2026 updated by: Rijnstate Hospital

Gastric Emptying Measured With MRI and Scintigraphy in Patients With Successful Versus Unsuccessful Weight Loss After Sleeve Gastrectomy

Sleeve gastrectomy (SG) increases gastrointestinal motility, which influences feelings of fullness and satiety. By understanding the differences in gastric emptying (GE) between patients with sufficient weight loss (Total weight loss [TWL] > 35%) and insufficient weight loss (TWL < 25%), better insight in the aetiology of weight loss after sleeve gastrectomy may be obtained. GE will be measured with scintigraphy and MRI.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access 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.

Detailed Description

Sleeve gastrectomy (SG) increases gastrointestinal motility, which influences feelings of fullness and satiety. Patients' weight loss response on SG varies widely and is difficult to predict. By understanding the differences in gastric emptying (GE) between patients with sufficient weight loss (Total weight loss [TWL] > 35%) and insufficient weight loss (TWL < 25%), better insight in the aetiology of weight loss after sleeve gastrectomy may be obtained. GE will be measured with scintigraphy and MRI. MRI is a non-invasive imaging method which provides more detailed images of the SG compared to the conventionally used scintigraphy scans.

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.

Study Population

Women after sleeve gastrectomy with either good or poor weight loss

Description

Inclusion Criteria:

  • Women aged between 20 and 55 years who underwent sleeve gastrectomy as primary procedure with either TWL < 25% or TWL > 35%.
  • Patients who had a follow-up period of 2-3 years after sleeve gastrectomy

Exclusion Criteria:

  • Maximum BMI >50 kg/m2

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
Gastric emptying compared between patients with poor and successful weight loss
Time Frame: 2-3 years
Gastric emptying (T1/2 [min] and retention [%/min])
2-3 years
Gastric emptying compared between measured with MRI and scintigraphy
Time Frame: 2-3 years
Gastric emptying (T1/2 [min] and retention [%/min])
2-3 years

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
Sleeve characteristics compared between patients with successful and unsuccessful (poor) weight loss
Time Frame: 2-3 years
Volume (sleeve size [mL] and gastric acid [mL])
2-3 years
to assess the association between gastric emptying rate and gastric sleeve characteristics in each group
Time Frame: 2-3 years
association between outcome 1, 2 and 3
2-3 years
to compare subjective ratings of gastric fullness and wellbeing between patients with successful and unsuccessful weight loss
Time Frame: 2-3 years
questionnaires (VAS-scale, MAIA, HADS, EBBS, Power of food scale, and Food tolerance test)
