Indications for gastroscopy are basically all kinds of pain in upper abdominal area, that can suggest anomalies arose in esophagus, stomach or duodenum. Gastroscopy is also a main examination conducted in suspected peptic ulcer disease or its complications.
This examination should also be performed in case of people after age 45 with stomach ailments and younger patients in case of whom, there is a need of diagnosis or when alarming signals (as loss of weight, swallowing disorders, anemia, hematemesis) occur.
Diagnostic gastroscopy is conducted for indications listed below:
-dyspepsia (abdominal pain, belching, bloating, heartburn)
- suspected peptic ulcer disease
-painful swallowing and swallowing difficulties
-gastrointestinal tract bleeding or its suspicion
-suspected drug-induced damages to the mucous membrane in upper gastro-intestinal track in group of patients after long term non-steroidal anti-inflammatory and analgesic drug treatment.
-screening test or control study in case of patients with increased risk of cancer (patients with long term gastroesophageal reflux disease, Barrett syndrome, pernicious anaemia with atrophic gastritis, after a gastrectomy).
Gastroscopy can be both a diagnostic method and a therapeutic procedure consisting in foreign body removal from the upper part of gastrointestinal tract, stopping the bleeding, polypectomy or endoscopic widening of constrictions.
Polypectomy is conducted with use of an flexible wire loop which is inserted by a bioptic channel onto a protuberant polyp. After grabbing a polyp, high-frequency electromagnetic currents is let through the loop which cuts it off. This procedure is painless.
During gastroscopy it is also possible to find and remove a foreign body e.g. a fishbone stuck in the esophagus.
