JGES guidelines for colorectal endoscopic submucosal dissection/endoscopic mucosal resection.

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Colorectal endoscopic submucosal dissection (ESD) is increasingly used for early colorectal cancers and precancerous adenomas.
• Establishing practical guidelines for preoperative diagnosis and endoscopic treatment selection is crucial for safe and effective procedures.

Purpose of the Study:

• To compile evidence-based guidelines for colorectal endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR).
• To outline diagnostic and therapeutic strategies, including considerations before, during, and after ESD/EMR.

Main Methods:

• Development of guidelines by the Japan Gastroenterological Endoscopy Society in collaboration with major Japanese gastroenterological societies.
• Utilized evidence-based methods, with recommendations largely based on expert consensus due to limited evidence in specific areas.

Main Results:

• Guidelines cover diagnostic and therapeutic strategies for colorectal ESD/EMR.
• Recommendations address indications, preoperative diagnosis, and procedural considerations, excluding specific technical details of instruments or drugs.

Conclusions:

• The compiled guidelines provide a framework for the safe and effective endoscopic treatment of colorectal neoplasia.
• Expert consensus played a significant role in establishing recommendations where evidence was scarce.
