Gastroscopy (Diagnostic and Therapeutic)
Gastroscopy is a procedure where the oesophagus, stomach and first part of the small bowel are visualised with a camera attached to the end of a flexible tube passed through the mouth. Reasons for this procedure to be performed include.
Unexplained low haemoglobin or iron levels (anaemia) and is usually performed in conjunction with a colonoscopy
Bleeding from the upper gastrointestinal tract (vomiting blood or passing blood per rectum)
Difficulty in swallowing (Dysphagia)
Painful swallowing (Odynophagia)
Chronic peptic ulcer (Gastric or duodenal ulcer)
After gastric surgery (raised incidence of gastric cancer)
Abnormalities on barium examination
Coeliac disease (via biopsy)
Treatment of oesophageal varices by banding, injection or balloon tamponade.
Injection of bleeding ulcers
Cutting off of larger pieces of tissue with a snare device (e.g. polyps, endoscopic mucosal resection)
PEG (Percutaneous endoscopic gastrostomy) feeding tube placement
Endoscopic retrograde cholangiopancreatography (ERCP)
Endoscopic ultrasound (EUS)
Cauterisation of angiomata, bleeding ulcers or aberrant tissue.
Retrieval of foreign bodies
Photodynamic therapy for premalignant oesophageal conditions
Drainage of pancreatic pseudocysts
Treatment of oesophageal strictures or achalasia by dilation and or stenting
