Endoscopic Mucosal Resection (EMR)

ENDOSCOPIC MUCOSAL RESECTION (EMR)

Endoscopic Mucosal Resection (EMR) is a minimally invasive procedure used to remove abnormal, pre-cancerous, or early-stage cancerous lesions from the esophagus, stomach, colon, or rectum without the need for open surgery.

What is Endoscopic Mucosal Resection (EMR)?

Endoscopic Mucosal Resection (EMR) is a minimally invasive procedure used to remove abnormal or precancerous lesions, early-stage cancers, or polyps from the gastrointestinal (GI) tract, primarily in the esophagus, stomach, or colon. It allows for tissue removal without the need for open surgery.

Endoscopic mucosal resection (EMR) is a minimally invasive procedure that removes abnormal tissue from the digestive tract. It’s used to treat early-stage cancer, precancerous lesions, and other abnormal tissue.

Why is EMR Performed?

EMR is used to treat and diagnose:

1. Early-stage gastrointestinal cancers (esophageal, gastric, or colorectal cancer)
2. Precancerous lesions (e.g., Barrett’s esophagus with dysplasia)
3. Large polyps that cannot be removed with standard polypectomy
4. Benign tumors in the GI tract

Procedure Overview:

Preparation:
Fasting for 6-8 hours before the procedure.
Bowel preparation (for colonic EMR) to clear the intestines.
Sedation:
Given under conscious sedation or general anesthesia.
Endoscope Insertion:
A flexible tube with a camera is inserted through the mouth or rectum.
Lesion Identification & Marking:
The target area is identified, and sometimes marked with dye.
Submucosal Injection:
A fluid (saline or a special solution) is injected under the lesion to lift it and separate it from deeper layers.
Resection (Removal):
A snare loop or electrocautery is used to cut and remove the lesion.
The specimen is collected for biopsy.
Hemostasis (Bleeding Control):
Clips or coagulation may be used to stop bleeding if needed.
Completion & Recovery:
The procedure takes 30-90 minutes, depending on the lesion size.
Patients are monitored for a few hours before discharge.

Risks and Aftercare:

1. Mild discomfort or bloating.
2. Rare risks: bleeding, perforation, or infection.
3. Avoid solid foods and alcohol for 24 hours post-procedure.
4. Follow-up endoscopy may be needed for surveillance.
