Using Pronase to Improve Mucosal Cleanliness During EGD

The Effects of Premedication With Pronase and Postural Exercise on Mucosal Cleanliness During Painless Esophagogastroduodenoscopy: A Prospective, Multicenter, Randomized Controlled Study Based on Artificial Intelligence Assessment

Not applicable Interventional Changhai Hospital · NCT06713421

This study is testing whether using a medication called pronase along with some exercises can help make it easier to see inside the esophagus and stomach during an EGD for patients with esophageal and gastric cancer.

What this trial studies

This study investigates the effect of premedication with pronase and dimethicone on mucosal cleanliness during esophagogastroduodenoscopy (EGD) in patients with esophageal and gastric cancer. It aims to determine whether adding postural exercises enhances the effectiveness of these medications in improving visibility during the procedure. The study will compare different intervention groups to assess the impact on mucosal cleanliness and the potential for better detection of lesions. The findings could provide insights into optimizing EGD procedures for better diagnostic outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 who are undergoing EGD for suspected upper gastrointestinal issues.

Not a fit: Patients with active gastrointestinal bleeding, severe comorbidities, or a history of upper gastrointestinal surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved detection rates of upper gastrointestinal lesions, reducing the risk of missed diagnoses in patients.

How similar studies have performed: Previous studies have suggested improvements in mucosal cleanliness with similar premedication approaches, but this study aims to provide more robust evidence.
