What Is the Management of a Small Submucosal Gastrointestinal Stromal Tumor in the Esophagogastric or Duodenal Region?

When a submucosal lesion smaller than 2 cm is found in the esophagogastric junction or duodenum and GIST is suspected, a dedicated clinical pathway determines how to proceed — beginning with endoscopic evaluation.

Clinical Scenario

Esophagogastric or duodenal submucosal gastrointestinal stromal tumor smaller than 2 cm. These small lesions require careful characterisation before any therapeutic decision is made, as management differs from larger or more advanced GISTs.

Approach Overview

Primary management is guided by endoscopic ultrasound. What follows — and which further steps apply — depends on the findings obtained. The complete decision pathway, including all management options and their respective criteria, is set out in the full structured protocol.
