Advanced polyp removal is a specialised medical procedure used to excise large or complex polyps from the gastrointestinal (GI) tract, primarily from the colon or rectum. This minimally invasive approach aims to prevent complications such as cancer or obstruction while avoiding the need for major surgery.

Advanced Polyp Removal?

Advanced polyp removal involves the use of specialised endoscopic techniques to safely and effectively remove polyps that are too large, flat, or otherwise challenging to address with standard methods. These techniques may include:

• Endoscopic mucosal resection (EMR): Removal of polyps from the superficial layers of the GI tract.
• Endoscopic submucosal dissection (ESD): A more complex technique allowing the removal of deeper or larger polyps in a single piece.

Why Do You Do This Procedure?

The procedure is performed to:

• Remove polyps that pose a risk of progressing to cancer, particularly adenomas.
• Alleviate symptoms caused by large polyps, such as bleeding or obstruction.
• Avoid the need for surgical resection, preserving bowel function and reducing recovery time.

It is both a diagnostic and therapeutic procedure, as removed polyps are sent for histological analysis to determine if they contain cancerous or pre-cancerous cells.

When Does This Procedure Happen?

Advanced polyp removal is recommended when:

• Polyps are detected during routine screening (e.g., colonoscopy) and are deemed too large or complex for standard techniques.
• Symptoms such as rectal bleeding, changes in bowel habits, or abdominal pain suggest the presence of a problematic polyp.
• Polyps are suspected or confirmed to be pre-cancerous or early-stage cancerous lesions.

The procedure is typically scheduled after a thorough evaluation, including imaging or biopsy, to determine the polyp’s size, location, and characteristics.

What Condition Does This Treat?

Advanced polyp removal is primarily used to manage and treat:

• Adenomatous polyps: Pre-cancerous growths in the colon or rectum.
• Sessile or flat polyps: Difficult-to-remove lesions that pose a higher risk of malignancy.
• Large polyps: Those that obstruct the bowel or bleed persistently.
• Early-stage colorectal cancer: In cases where the lesion is confined and accessible endoscopically.
