Endoscopy
Diagnostic and therapeutic endoscopy — looking inside the digestive tract and treating problems without open surgery.
A thin camera examines the food pipe, stomach and duodenum to find the cause of acidity, pain, bleeding or difficulty swallowing — and to take biopsies.
View treatment ColonoscopyA camera examines the entire large intestine to investigate bleeding, change in bowel habit or pain, screen for cancer and remove polyps in the same sitting.
View treatment EnteroscopySpecialised endoscopy of the small intestine — the part beyond the reach of a standard gastroscopy or colonoscopy — to find hidden bleeding or disease.
View treatment ERCPAn endoscopic procedure that clears bile-duct stones, relieves blocked bile ducts and places stents — avoiding open surgery for many biliary problems.
View treatment EUS (Endoscopic Ultrasound)Combines endoscopy with ultrasound to image the pancreas, bile duct and gut wall in fine detail and to take precise needle biopsies.
View treatment ManometryMeasures the muscle function and pressures of the food pipe to diagnose swallowing disorders and confirm reflux before anti-reflux surgery.
View treatment StentingA self-expanding stent relieves a blocked food pipe, stomach outlet, bile duct or bowel — restoring passage and comfort, often without surgery.
View treatment PolypectomyRemoval of polyps during colonoscopy or gastroscopy — taking out growths before they can turn into cancer.
View treatment Foreign Body RemovalEndoscopic removal of swallowed objects or stuck food from the food pipe or stomach — a safe alternative to open surgery.
View treatment Gastric BalloonA soft balloon placed in the stomach by endoscopy to reduce appetite and kick-start weight loss — non-surgical and reversible.
View treatmentAfter years of acidity, the keyhole surgery finally fixed it. Honest advice, no pressure, excellent result.
Laparoscopy

View treatment Inguinal HerniaLaparoscopic repair of a groin hernia — the most common hernia, fixed with mesh for a durable, low-recurrence result.
View treatment Femoral HerniaRepair of a hernia low in the groin/thigh — more prone to obstruction, so prompt key-hole repair is advised.
View treatment Hiatus HerniaRepair of a hernia where the stomach slides into the chest — often the cause of stubborn reflux; corrected with anti-reflux surgery.
View treatment SpleenLaparoscopic spleen surgery (splenectomy) for blood disorders, enlargement or trauma — performed with key-hole precision.
View treatment RectumLaparoscopic surgery for rectal conditions including prolapse and rectal cancer — restoring function with minimally-invasive technique.
