Procedures

01Colonoscopy Colonoscopy

Colonoscopy is an endoscopic examination of the large intestine using a thin flexible camera. It diagnoses bleeding, polyps and cancer, and can remove polyps in the same sitting — preventing colon cancer before it starts.

02Gastroscopy (Upper GI Endoscopy) Gastroscopy (Upper GI Endoscopy)

Gastroscopy is a quick, sedated examination of the food pipe, stomach and duodenum with a thin flexible camera. It investigates acidity, ulcers, swallowing problems, bleeding and early cancer — and allows a biopsy to be taken in the same sitting.

Learn more
03 ERCP (Bile Duct Endoscopy)

ERCP is an advanced endoscopic procedure that treats problems of the bile and pancreatic ducts — clearing bile-duct stones, relieving blockages and placing stents — without the need for open surgery.

Learn more
04EUS (Endoscopic Ultrasound) EUS (Endoscopic Ultrasound)

EUS combines endoscopy with high-resolution ultrasound to image the pancreas, bile duct and gut wall in fine detail — and to take precise, minimally invasive needle biopsies of deep lesions that are hard to reach any other way.

Learn more
05Stenting (Endoscopic) Stenting (Endoscopic)

Endoscopic stenting places a small expandable tube to relieve a narrowed or blocked food pipe, bile duct, stomach outlet or bowel — restoring passage, relieving jaundice or allowing eating, often without open surgery.

Learn more
06PEG (Feeding Tube Placement) PEG (Feeding Tube Placement)

PEG (percutaneous endoscopic gastrostomy) is an endoscopic technique to place a feeding tube directly into the stomach, providing safe, comfortable nutrition for people who cannot eat normally for a prolonged period.

Learn more
07 POEM (Per-Oral Endoscopic Myotomy)

POEM is an advanced, incision-less endoscopic procedure that treats achalasia and related swallowing disorders by releasing the tight muscle at the lower end of the food pipe — restoring normal swallowing with no external cuts.
