Trial Identification

Brief Title: Hydrogel Injection to Assist Endoscopic Submucosal Dissection

Official Title: Gut Guarding Gel for Endoscopic Resection to Treat Early Gastroenterological Tumor and Polyps (Evaluation of the Safety of Sodium Alginate Mixed With Calcium Lactate on Endoscopic Mucosal Resection / Endoscopic Submucosal Dissection)

Study ID: NCT03321396

Conditions

Submucosal Tumor of Gastrointestinal Tract

Interventions

sodium alginate mixed with calcium lactate

Study Description

Brief Summary: The aim of the investigators' study is to evaluate the mucosa-elevating capacity and clinical safety of Sodium Alginate (SA) mixed with Calcium Lactate in assisting Endoscopic Submucosal Dissection/Endoscopic Mucosal Resection.

Detailed Description: The study will evaluate the mucosa-elevating capacity and clinical safety of Gut Guarding Gel (the Sodium Alginate (SA) mixed with Calcium Lactate) in assisting Endoscopic Submucosal Dissection/Endoscopic Mucosal Resection to treat early gastroenterological tumor and polyps. All participants in the study received Endoscopic submucosal dissection with Sodium Alginate mixed with Calcium Lactate prior to endoscopic resection. The product is used in Endoscopic submucosal dissection which is accomplished by steps listed as follows: lesion marking, submucosal injection, mucosal incision, submucosal dissection, then en-bloc resection. It's a new submucosal injection regimen, sodium alginate mixed with calcium lactate, which turned to calcium-alginate gel, we called it as "Gut Guarding Gel". Determine the rates of the delayed bleeding/perforation, postpolypectomy electrocoagulation syndrome, and the late tissue injury.
