Do you have what it takes for challenging endoscopic submucosal dissection cases?

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Oncology

Background:

• Endoscopic submucosal dissection (ESD) is a standard treatment for early gastric cancer (EGC), particularly in East Asia.
• Recent expansions in therapeutic criteria for ESD in EGC necessitate addressing technical challenges.
• Lesion characteristics like location, size, and fibrosis, along with operator expertise, significantly impact ESD feasibility.

Purpose of the Study:

• To describe the endoscopic submucosal dissection (ESD) procedure for managing early gastric cancer (EGC) lesions with high technical difficulty.
• To highlight the critical role of operator experience in the successful execution of ESD for complex cases.

Main Methods:

• Detailed description of the ESD procedure tailored for difficult-to-resect EGC lesions.
• Emphasis on specific techniques and considerations for managing challenging anatomical locations, larger sizes, or fibrotic submucosa.
• Case illustrations or procedural steps may be included to demonstrate the approach.

Main Results:

• Successful application of ESD for early gastric cancer (EGC) lesions previously considered high-risk or difficult.
• Demonstration of techniques that overcome challenges related to lesion characteristics and anatomical location.
• The importance of tailored approaches based on lesion complexity and surgeon's experience was underscored.

Conclusions:

• Endoscopic submucosal dissection (ESD) is technically feasible for a broader range of early gastric cancer (EGC) lesions, including those with high difficulty.
• Operator experience is paramount for achieving successful outcomes in complex ESD cases.
• Careful patient selection and procedural adaptation based on lesion characteristics and operator skill are crucial for safe and effective ESD treatment of EGC.
