### SCOPE

#### DISEASE/CONDITION(S)

Gastric emptying and motility disorders

#### GUIDELINE CATEGORY

Diagnosis\
Evaluation

#### CLINICAL SPECIALTY

Nuclear Medicine\
Radiology

#### INTENDED USERS

Allied Health Personnel\
Physicians

#### GUIDELINE OBJECTIVE(S)

To assist nuclear medicine practitioners in recommending, performing,
interpreting, and reporting the results of gastric emptying/motility
studies

#### TARGET POPULATION

Adults and children with suspected or documented gastric motility
disturbances

#### INTERVENTIONS AND PRACTICES CONSIDERED

Radionuclide studies of gastric emptying and motility

#### MAJOR OUTCOMES CONSIDERED

Not stated

### METHODOLOGY

#### METHODS USED TO COLLECT/SELECT EVIDENCE

Hand-searches of Published Literature (Primary Sources)\
Hand-searches of Published Literature (Secondary Sources)\
Searches of Electronic Databases

#### DESCRIPTION OF METHODS USED TO COLLECT/SELECT THE EVIDENCE

Literature searches were performed. In addition, references known to
experts and references from the nuclear medicine community were
considered.

#### NUMBER OF SOURCE DOCUMENTS

Not stated

#### METHODS USED TO ASSESS THE QUALITY AND STRENGTH OF THE EVIDENCE

Not stated

#### RATING SCHEME FOR THE STRENGTH OF THE EVIDENCE

Not applicable

#### METHODS USED TO ANALYZE THE EVIDENCE

Review

#### DESCRIPTION OF THE METHODS USED TO ANALYZE THE EVIDENCE

Not stated

#### METHODS USED TO FORMULATE THE RECOMMENDATIONS

Expert Consensus

#### DESCRIPTION OF METHODS USED TO FORMULATE THE RECOMMENDATIONS

Drafts of the guideline were submitted to members of the Guideline
Development subcommittee (methodologists) and the Task Force (subject
experts). These reviewers indicated on a line-by-line basis any
suggestions or recommendations for the revision of the guideline. The
percentage of agreement for all reviewers was calculated for each
revision and compiled by the Society of Nuclear Medicine (SNM) central
office. It is expected that the percentage of agreement will increase
with each revision.

#### RATING SCHEME FOR THE STRENGTH OF THE RECOMMENDATIONS

Not applicable

#### COST ANALYSIS

A formal cost analysis was not performed and published cost analyses
were not reviewed.

#### METHOD OF GUIDELINE VALIDATION

Internal Peer Review

#### DESCRIPTION OF METHOD OF GUIDELINE VALIDATION

When the Task Force and Guideline Development Subcommittee completed
their edits, draft procedure guidelines were distributed to the Society
of Nuclear Medicine (SNM) Sample Review Group for comment. (The SNM
Sample Review Group is a cross-section of approximately 100 nuclear
medicine practitioners representing every field of specialization).

The guideline was approved by the SNM Commission on Health Care Policy,
the Board of Directors, and the House of Delegates.

The update was approved June 6, 2004.

### RECOMMENDATIONS

#### MAJOR RECOMMENDATIONS

**Background Information and Definitions**

Radionuclide studies of gastric emptying and motility are the most
physiologic studies available for studying gastric motor function. The
study is noninvasive, uses a physiologic meal (solids with/without
liquids), and is quantitative. Serial testing can determine the
effectiveness of therapy.

**Examples of Clinical or Research Applications**

A.  Postprandial:

    1.  Nausea, vomiting

    2.  Upper abdominal discomfort, bloating

    3.  Chronic aspiration

B.  Suspected gastroparesis

C.  Poor diabetic control

D.  Gastroesophageal reflux

E.  Following response to therapy for previously document motility
    disturbances

**Procedure**

The detailed procedure recommendations in the guideline address the
following areas: patient preparation; information pertinent to
performing the procedure (i.e., important data that the physician should
have about the patient at the time the exam is performed and
interpreted); precautions/contraindications; information regarding the
radiopharmaceutical (i.e., ranges of administered activity, organ
receiving the largest radiation dose, effective dose), image
acquisition; interventions; processing; interpretation/reporting;
quality control, and sources of error.

#### CLINICAL ALGORITHM(S)

None provided

### EVIDENCE SUPPORTING THE RECOMMENDATIONS

#### TYPE OF EVIDENCE SUPPORTING THE RECOMMENDATIONS

The type of evidence supporting the recommendations is not specifically
stated.

### BENEFITS/HARMS OF IMPLEMENTING THE GUIDELINE RECOMMENDATIONS

#### POTENTIAL BENEFITS

The intent of the procedure guideline is to describe radionuclide
studies of gastric emptying and motility, in order to maximize the
diagnostic information obtained in the study while minimizing the
resources that are expended.

#### POTENTIAL HARMS

Not stated

### CONTRAINDICATIONS

#### CONTRAINDICATIONS

-   Allergy to the meal

-   Fasting in diabetic patients resulting in hypoglycemia

### QUALIFYING STATEMENTS

#### QUALIFYING STATEMENTS

-   The Society of Nuclear Medicine (SNM) has written and approved these
    guidelines as an educational tool to promote the cost-effective use
    of high quality nuclear medicine procedures or in the conduct of
    research and to assist practitioners in providing appropriate care
    for patients. The guidelines should not be deemed inclusive of all
    proper procedures nor exclusive of other procedures reasonably
    directed to obtaining the same results. They are neither inflexible
    rules nor requirements of practice and are not intended nor should
    they be used to establish a legal standard of care. For these
    reasons, SNM cautions against the use of these guidelines in
    litigation in which the clinical decisions of a practitioner are
    called into question.

-   The ultimate judgment about the propriety of any specific procedure
    or course of action must be made by the physician when considering
    the circumstances presented. Thus, an approach that differs from the
    guidelines is not necessarily below the standard of care. A
    conscientious practitioner may responsibly adopt a course of action
    different from that set forth in the guidelines when, in his or her
    reasonable judgment, such course of action is indicated by the
    condition of the patient, limitations on available resources, or
    advances in knowledge or technology subsequent to publication of the
    guidelines.

-   All that should be expected is that practitioner will follow a
    reasonable course of action based on current knowledge, available
    resources, and the needs of the patient to deliver effective and
    safe medical care. The sole purpose of these guidelines is to assist
    practitioners in achieving this objective.

-   Advances in medicine occur at a rapid rate. The date of a guideline
    should always be considered in determining its current
    applicability.
