Summary
Endoscopic mucosal resection (EMR) allows removal of large digestive tissue samples for superficial lesions. Proper handling and detailed histological analysis are crucial for accurate staging and treatment, requiring close endoscopist-pathologist collaboration.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Histopathology
Context:
- Endoscopic mucosal resection (EMR) is an advanced endoscopic technique for resecting large digestive mucosa fragments.
- Indications include staging and treatment of superficial lesions in the esophagus, stomach, and colon.
Purpose:
- To outline the specific macroscopic and histological challenges associated with endoscopic mucosal resection specimens.
- To emphasize the critical steps for proper specimen handling and histological reporting.
Summary:
- EMR fragments require specific techniques for inclusion, including pinning under a rigid support and independent sampling of lateral margins.
- Histological reports must detail resection depth and margin status (lateral and deep).
- Coagulation artifacts are a common challenge, potentially hindering accurate interpretation, especially at lateral margins.
Impact:
- Ensuring accurate histological analysis of EMR specimens is vital for effective patient management.
- Highlights the necessity of strong collaboration between endoscopists and pathologists for optimal outcomes in EMR procedures.
