Gastrointestinal cancer
Most people investigated for cancer symptoms don't have cancer — but the ones who do are best served by rapid diagnosis and, where it's caught early, treatment through the endoscope rather than surgery.
Symptoms that need investigating
Difficulty swallowing, food sticking, unexplained weight loss, persistent vomiting, new upper abdominal pain, anaemia, vomiting blood or passing black stools all warrant timely endoscopy. A change in bowel habit or rectal bleeding warrants colonoscopy. Private investigation means these questions are answered within days rather than months.
Dr Zeki's expertise
Upper gastrointestinal cancer and its precursors are the centre of Dr Zeki's academic career — his PhD examined the genomics of oesophageal cancer, and his clinical practice includes the endoscopic detection and resection of early cancers of the oesophagus and stomach. Detection at this stage is the difference between an endoscopic day‑case procedure and major surgery.
Diagnosis and treatment
- High‑quality gastroscopy and colonoscopy in JAG‑accredited units, with meticulous inspection — the quality of the examination determines what gets found
- Endoscopic mucosal resection and submucosal dissection of early lesions, removing them completely without external surgery
- Surveillance of pre‑cancerous conditions including Barrett's oesophagus and gastric precursor changes
- Care coordinated through specialist multidisciplinary teams at one of the UK's leading cancer centres
