Endoscopy and reflux testing
Dr Zeki performs endoscopy in JAG‑accredited units at London Bridge Hospital, and personally delivers the full suite of oesophageal physiology testing — a combination few London practices offer under one consultant.
Gastroscopy (OGD)
A thin, flexible camera examines the oesophagus, stomach and duodenum — the definitive test for reflux complications, swallowing problems, ulcers and anaemia, with biopsies taken wherever they add information. Performed with throat spray or sedation, as you prefer; the examination itself takes under ten minutes.
Colonoscopy
Examination of the large bowel for bleeding, change in bowel habit, anaemia and bowel cancer screening, with polyps removed at the same visit. Performed under sedation in a JAG‑accredited unit with meticulous attention to examination quality — the measure that actually determines how much a colonoscopy protects you.
BRAVO wireless pH monitoring
The modern way to prove — or disprove — acid reflux. A capsule the size of a pencil eraser is attached painlessly to the oesophageal lining during gastroscopy and transmits acid readings to a small receiver for up to 96 hours while you eat, work and sleep normally. No tube down the nose, and the extended recording substantially increases diagnostic accuracy compared with 24‑hour catheter studies. The capsule detaches and passes naturally after a few days.
24‑hour pH‑impedance monitoring
A fine catheter measures both acid and non‑acid reflux and — critically — correlates every reflux episode with the symptoms you record. This is the test that answers the hardest question in reflux medicine: are your symptoms actually caused by reflux? Essential when medication hasn't worked or surgery is being considered.
High‑resolution oesophageal manometry
A pressure‑sensing catheter maps every swallow along the length of the oesophagus, diagnosing motility disorders — achalasia, spasm, ineffective motility — against the international Chicago Classification. Oesophageal physiology is Dr Zeki's subspecialty: he performs and interprets these studies personally, and manometry is mandatory before any anti‑reflux surgery.
Therapeutic endoscopy
Beyond diagnosis, Dr Zeki performs endoscopic dilatation of strictures, removal of polyps, endoscopic mucosal resection and submucosal dissection of early cancers, and radiofrequency ablation for Barrett's oesophagus with dysplasia.
