Advanced endoscopy refers to specialized, minimally invasive procedures used to diagnose and treat complex gastrointestinal (GI) conditions. Unlike standard endoscopy, which focuses on visual examination, advanced techniques allow therapeutic interventions, real-time imaging, and tissue sampling with high precision.

1. Endoscopic Ultrasound (EUS)

• Combines endoscopy and ultrasound.

• Used for imaging and biopsy of organs like pancreas, liver, lymph nodes, and GI wall layers.

• Commonly used for cancer staging and drainage of cysts or abscesses.

2. Endoscopic Retrograde Cholangiopancreatography (ERCP)

• Visualizes bile ducts and pancreatic ducts.

• Helps remove stones, place stents, or take biopsies.

• Often used to manage gallstones, pancreatitis, and bile duct cancers.

3. Endoscopic Mucosal Resection (EMR) & Endoscopic Submucosal Dissection (ESD)

• Techniques to remove precancerous or cancerous lesions from the GI tract without surgery.

• ESD is more complex but allows removal of larger tumors in one piece.

4. Enteroscopy (Double Balloon / Single Balloon / Spiral)

• Designed to explore and treat diseases in the small intestine, which standard endoscopes cannot reach.

5. Endoluminal Therapies (e.g., POEM, TIF)

• POEM (Peroral Endoscopic Myotomy): Treats achalasia and other esophageal motility disorders.

• TIF (Transoral Incisionless Fundoplication): Used for treating GERD (acid reflux) without incisions.

6. Barrett’s Esophagus Ablation (e.g., RFA, Cryotherapy)

• Techniques used to destroy abnormal esophageal lining before it turns cancerous.
