Hematopoietic and Lymphoid System Neoplasm, Malignant Solid Neoplasm
Conditions
Brief summary
This study creates a patient registry of patients undergoing contrast-enhances-harmonic endoscopic ultrasound imaging. In order to improve what doctors see on the ultrasound exam, sometimes intravenous contrast can be used to better emphasize the blood flow in a particular organ or lesion. Creating a local database that can be used as a patients registry may help doctors keep track of all patients that undergo contrast-enhanced endoscopic ultrasound procedures and also to monitor for possible procedure adverse events.
Detailed description
PRIMARY OBJECTIVE: I. To describe the findings and outcomes of patient undergoing contrast-enhanced harmonic endoscopic ultrasound (CE-EUS) imaging. OUTLINE: This is an observational study. Patients who have undergo contrast-enhanced harmonic endoscopic ultrasound imaging have their medical records reviewed.

Inclusion criteria
* Male and female patients aged 18 years to 99 years old who were undergo CE-EUS are eligible for study inclusion * Based on clinical judgement of the advanced endoscopist will include those who present with lesions where increased microvasculature and perfusion visualization with contrast-enhanced harmonic endoscopic ultrasound imaging would be of beneficial for lesion characterization * Clinical medical stability to undergo sedation for endoscopy and provide informed consent
Exclusion criteria
* Medical condition that preclude the patient from having an endoscopic procedure * Patients who cannot provide adequate research authorization * Patients with known allergies to ultrasound contrast agents * Patient who did not receive contrast during endoscopic ultrasound (EUS) exams
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analyse continuous variable outcomes of patient undergoing contrast-enhanced harmonic endoscopic ultrasound imaging using medical record review and T-tests or Mann-Whitney U test. | Up to 5 years | Descriptive statistical analysis will be carried out at routine intervals for database analysis. Two-sided P values less than 0.05 will be considered statistically significant. For descriptive analyses, continuous variables will be reported as a mean +/- standard deviation or median (interquartile range) and compared based on either T-tests or Mann-Whitney U test. |
| Analyse categorical variable outcomes of patient undergoing contrast-enhanced harmonic endoscopic ultrasound imaging using medical record review and chi-square test or Fisher's exact test. | Up to 5 years | Descriptive statistical analysis will be carried out at routine intervals for database analysis. Two-sided P values less than 0.05 will be considered statistically significant. Categorical variables will be reported as frequencies with percentages and compared using the chi-square test or Fisher's exact test. |
| Analyse multivariables of patient undergoing contrast-enhanced harmonic endoscopic ultrasound imaging using medical record review and logistic regression or linear regression analyses depending on the outcome. | Up to 5 years | Descriptive statistical analysis will be carried out at routine intervals for database analysis. Two-sided P values less than 0.05 will be considered statistically significant. Multivariable analyses will be performed using logistic regression or linear regression analyses depending on the outcome, i.e. dichotomous or continuous respectively. |
