upper-GI endoscopyA procedure in which a fiberoptic oesophagogastroduodenoscope, is inserted by mouth and the mucosal surfaces of the oesophagus, stomach, duodenum, and proximal jejunum are examined for ulcers, polyps, tumours, bleeding sites, strictures, and other changes. During the procedure, suspicious lesions may be sampled and specimens submitted for culture, histology or other studies.
UGE is used to evaluate acute upper-GI bleeding (e.g., of the oesophagus in cirrhosis, dysphagia) which may be due to strictures, dyspepsia, oesophageal pain, and evaluate changes seen by an upper-GI study, to identify causes of the gastric outlet syndrome, and to monitor premalignant conditions (e.g., Barrett’s oesophagus, lye-induced strictures); “low-yield” indications for upper-GI endoscopy include atypical chest pain, abdominal pain of unknown origin.
