Mayo Clinic Upper Digestive Disease Survey (UDD)

March 24, 2026 updated by: Luis F. Tapias Vargas, Mayo Clinic
The Mayo Clinic Conduit Report Card Questionnaires have been created in order to have a consistent evaluation tools for patients undergoing esophageal reconstruction or treatment or patients that are experiencing an upper digestive disease in order to standardize and validate outcome measures. Data will be used to establish the validation of the questionnaires/survey. Data will also lead to the establishment of "normal" or expected scores for patients undergoing each type of esophagectomy procedure and for upper digestive diseases. Data will contribute to creating treatment algorithms for symptom management for upper digestive diseases and for post-operative complications and symptoms as well as contribute to pre-operative education.

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

Detailed Description

The Mayo Clinic Conduit Report Card Questionnaires are a compilation of standard questionnaires and questions that have been created specifically for this study some of which are patient report and others that are administered by the provider or study staff. It includes the Promis Global Health Score, modified Mayo GER Score questions, modified Dysphagia Questionnaire-30 Day questions, and Zubrod Score. It also includes a 10-point scale to grade postoperative pain, milk assessment, Modified Mayo Reflux Score adapted from the Mayo Clinic Reflux Score, Dumping Score adapted from Sigstad's Scoring System, Simple Dysphagia Score adapted from Mellows and Pinkas, Stricture Score adapted from Blackmon, et al., Pyloric Spasm Score, and Conduit Emptying Score abstracted from Vaezi, Baker, Achkar, and Richter. We will also be collecting information on their demographics, operation, nutritional status, laboratory values, testing results and clinical outcomes.

Patients will be asked to complete the Mayo Clinic Upper Digestive Disease Survey at their one month surgical follow up visit and then every three months for 1 year after surgery, then with each surveillance clinic visit or a minimum of once per year for their lifetime for patients who undergo surgery and at one month following diagnosis and then every three months for 1 year after diagnosis, then with each surveillance clinic visit or a minimum of once per year for their lifetime for patients that do not undergo surgery. The questionnaire can be completed at their clinic visit, over the telephone, or by mail using the paper form or may be completed using an electronic application. The electronic version is available for Mayo Clinic and non Mayo Clinic patients through the app store in conjunction Mayo IT.

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

Sampling Method

Non-Probability Sample

Study Population

Patients undergoing or having already undergone an esophagectomy or esophageal reconstruction.

Description

Inclusion Criteria:

  • Patients undergoing or having already undergone an esophagectomy or esophageal reconstruction.

Esophagectomy/Esophageal Reconstruction/Treatment
Patients who have undergone esophagectomy, esophageal reconstruction, or treatment
Other: Mayo Clinic Upper Digestive Disease Survey on Paper
Mayo Clinic patients will be asked to complete the Mayo Clinic Upper Digestive Disease Survey at their one month surgical follow up visit and then every three months for 1 year after surgery, then with each surveillance clinic visit or a minimum of once per year for their lifetime. The questionnaire can be completed at their clinic visit, over the telephone, or by mail. The patient's medical record will also be reviewed to gather any other contributing information.
Other: Upper Digestive Disease (UDD Monitor) App

Mayo Clinic and non Mayo Clinic patients can participate by loading the app through the app store. Patient consent will be completed in the app. Patients will be asked to complete questionnaires at their 1.5 month surgical or diagnosis follow up and then every three months for 1 year after their surgery or diagnosis, then with each surveillance clinic visit or a minimum of once per year for their lifetime or as long as they want to participate.

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
Completion of the Mayo Clinic Upper Digestive Disease Survey by patients at varying time points following surgery
Time Frame: 1 year
Completed Mayo Clinic Upper Digestive Disease Survey will be analyzed and used to establish validation.
1 year

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.
