Comprehensive Upper Gastrointestinal Examination
Gastroscopy, also known as upper endoscopy or oesophagogastroduodenoscopy (OGD), provides direct visualisation of the oesophagus, stomach, and duodenum. This fundamental procedure forms the cornerstone of upper gastrointestinal diagnosis and treatment.
The Examination Process
A thin, flexible endoscope is gently passed through the mouth to examine the upper digestive tract. The procedure is performed under conscious sedation, ensuring patient comfort while allowing clear visualisation of the mucosa.
Diagnostic Capabilities
Gastroscopy effectively identifies:
- Peptic ulcers and gastritis
- Gastro-oesophageal reflux disease complications
- Barrett’s oesophagus
- Upper gastrointestinal bleeding sources
- Tumours or suspicious lesions
- Helicobacter pylori infection
- Coeliac disease changes
Therapeutic Applications
The procedure enables various treatments:
- Bleeding control through thermal therapy or injection
- Polyp removal and tissue sampling
- Foreign body retrieval
- Stricture dilation
- Varices banding for portal hypertension
Patient Comfort and Safety
Modern gastroscopy techniques prioritise patient comfort and safety. The procedure typically takes 15-30 minutes, and most patients return to normal activities the same day. Detailed preparation instructions ensure optimal examination conditions.
