Endoscopic Treatment for Gastric Subepithelial Tumor

Area of Science:

• Gastroenterology
• Surgical Endoscopy

Background:

• Gastric subepithelial tumors (SETs) are often asymptomatic and incidentally found.
• While surveillance suffices for most, some SETs require active management.
• Traditional surgical resection has limitations, especially for intraluminal tumors.

Purpose of the Study:

• To review indications, methods, and outcomes of endoscopic therapy for gastric SETs.
• To propose a classification of SETs based on therapeutic indications.
• To suggest an algorithm for endoscopic management of gastric SETs.

Main Methods:

• Review of current endoscopic resection techniques for gastric SETs.
• Discussion of indications and outcomes.
• Development of a management algorithm and classification system.

Main Results:

• Several endoscopic techniques are emerging for gastric SET resection.
• These include submucosal tunneling, EFTR, LECS, and non-exposure EFTR.
• The study proposes a framework for selecting appropriate endoscopic therapies.

Conclusions:

• Endoscopic resection is a feasible and evolving treatment for select gastric SETs.
• Advances in technology enable minimally invasive management.
• A structured approach aids in therapeutic decision-making for gastric SETs.
