Endoscopic mucosal resection (EMR) is a key treatment for early gastrointestinal cancers and lesions. While risks like bleeding exist, EMR offers a valuable therapeutic option for endoscopists.

Area of Science:

Gastroenterology
Endoscopic Procedures
Oncology

Background:

Endoscopic mucosal resection (EMR) is an established endoscopic technique.
It is utilized for premalignant and early-stage gastrointestinal (GI) malignancies, especially in the esophagus and colon.
EMR also assists in diagnosing and treating subepithelial lesions within the muscularis mucosa or submucosa.

Purpose of the Study:

To review the role and application of EMR in GI oncology.
To discuss the available devices and associated adverse events.
To emphasize the importance of endoscopist skill in managing EMR complications.

Main Methods:

Review of current literature on EMR for GI malignancies and subepithelial lesions.
Analysis of adverse event rates compared to other endoscopic interventions.

Discussion of dedicated EMR devices and procedural considerations.

Main Results:

EMR is a recognized therapy for early GI cancers (esophagus, colon) and certain subepithelial lesions.
Dedicated EMR devices enhance procedural feasibility.
Adverse event rates (bleeding, perforation) are higher than basic endoscopy but lower than endoscopic submucosal dissection (ESD).

Conclusions:

EMR is a valuable endoscopic intervention for specific GI conditions.
Skilled endoscopist management is crucial for optimizing outcomes and mitigating risks.
Understanding EMR's risk profile relative to other techniques like ESD is essential.
