Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Detection of early esophageal cancer in surrounding normal tissue can be challenging even for experienced examiners. The early detection is essential to determine the following treatment. Early stages of esophageal cancers can be treated by endoscopic resection whereas advanced neoplasia might lead to an Operation of the esophagus. Diagnosis is made usually by biopsies of suspicious lesions or untargeted quadrant biopsies. The electrical properties in inflammatory tissue and cancer can be sensed by electrical bioimpedance technique.

The aim of this study is to compare the impedance probe with the histological result and to investigate the feasibility of the new technique in detection of esophageal cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Detection of early esophageal cancer in surrounding normal tissue can be challenging even for experienced examiners. The early detection is essential to determine the following treatment. Early stages of esophageal cancers can be treated by endoscopic resection (ER) whereas advanced neoplasia might lead to esophagectomy. Diagnosis is made usually by biopsies of suspicious lesions or untargeted quadrant biopsies. The electrical properties in inflammatory tissue and dysplasia can be sensed by electrical bioimpedance technique. The aim of this study is to compare the impedance probe with the histological result and to investigate the feasibility of the new technique in detection of esophageal cancer.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

Observation group: patient who are planned for endoscopic resection because of known esophageal cancer. Immediately after retrieval the resected specimens will be investigated for their electrical impedance properties. The results of the impedance measurement are compared to the histological results.

Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

no masking

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Impedance

every resected tissue will measured by an impedance probe

Group Type EXPERIMENTAL

impedance

Intervention Type DEVICE

After endoscopic resection of early esophageal cancer, the tissue will be measured by an impedance probe between 10Hz-1000000Hz, 20mV. 8 gold electrodes have been integrated to the probe. The impedance will be measured in different ways between the elctrodes. There will be 10 measurements in total for each specimen.

Interventions
