Whether it is More Appropriate to Spray Lugol's Solution From Cervical Esophagus to Esophagogastric Junction

January 8, 2020 updated by: Xiuli Zuo, Shandong University
The aim of this study is to compare the effectiveness and safety of spraying Lugol's solution from cervical esophagus to esophagogastric junction (downward) and from esophagogastric junction to cervical esophagus (upward)during chromoendoscopy.

Study Overview

Detailed Description

Chromoendoscopy using Lugol's solution is effective for the detection of early esophageal squamous neoplasia. However, there is no study to investigate the sequence of Lugol's staining during endoscopic procedure.

The aim of this study is to compare the effectiveness and safety of spraying Lugol's solution from cervical esophagus to esophagogastric junction (downward) and from esophagogastric junction to cervical esophagus (upward)during chromoendoscopy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Image Quality
Time Frame: intraoperative
Image quality is blindly quantified by a 4-point scale from the endoscopists. A higher score representing higher image quality.
intraoperative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adverse events
Time Frame: 24 hours
Adverse events of the two groups.
24 hours
Dose
Time Frame: intraoperative
Usage of Lugol's solution in each group.
intraoperative
Effectiveness
Time Frame: 1 month
Detection rate of esophageal squamous cell carcinoma of the two groups.
1 month
Tolerance
Time Frame: intraoperative
The 4-point scale was used to assess the tolerance of endoscopist to the esophageal spasm caused by Lugol's solution which prevent endoscopy from passing. 1-4 means the resistance as intolerable, tolerable, mild, or non-existing.
intraoperative
