Written for patients, reviewed by the surgeons who perform this treatment.
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.
A gastroscopy (upper GI endoscopy) passes a slim flexible camera through the mouth to inspect the food pipe (esophagus), stomach and the first part of the small intestine (duodenum). It gives a direct, detailed view that scans cannot, making it the key test for upper-digestive symptoms.
Gastroscopy diagnoses reflux damage, hiatus hernia, gastritis, ulcers, H. pylori infection, narrowings and early cancers. It is also therapeutic — it can take biopsies, stop bleeding ulcers, remove small lesions and stretch narrowings, all without surgery.
After a few hours of fasting, the procedure is performed under light sedation or with a numbing throat spray and usually takes 10–15 minutes. Most people go home the same day; if sedation is used, you will need someone to accompany you.

DOCUMENTED CASE · COLONOSCOPY & POLYPECTOMY
1BEFORE TREATMENT
A patient in their 50s with a family history of colon cancer and subtle change in bowel habit, anxious about screening.
2TREATMENT
The polyp was lifted and excised endoscopically in full, with clear margins, during the same colonoscopy.
3AFTER TREATMENT
Pathology confirmed a pre-cancerous lesion removed completely — a cancer prevented. A surveillance schedule was set so any future polyps are caught equally early.
