Gastroscopic

Gastroscopic is an adjective relating to gastroscopy, the endoscopic examination of the upper part of the gastrointestinal tract using a gastroscope. The procedure, often called upper endoscopy or esophagogastroduodenoscopy (EGD), allows direct visualization of the esophagus, stomach, and duodenum and enables targeted biopsies or therapeutic interventions.

During the procedure, performed by a gastroenterologist, a flexible tube with a camera and light is passed through the mouth and advanced carefully through the esophagus, stomach, and into the duodenum. Patients typically fast for several hours beforehand. The exam may be performed under conscious sedation or with local throat anesthesia. Air or carbon dioxide is insufflated to improve visibility. Biopsies can be taken for histology or infection testing, and therapeutic actions such as polyp removal, hemostasis for bleeding, dilation of strictures, or clearing obstructions may be performed if indicated.

Indications for gastroscopic examination include persistent upper abdominal pain or dyspepsia, heartburn or reflux unresponsive to treatment, anemia of unknown origin, gastrointestinal bleeding, suspected ulcers or tumors, and surveillance for conditions such as Barrett’s esophagus. The procedure has a high diagnostic yield and is generally considered safe. Common temporary side effects include a sore throat and mild bloating; serious complications such as bleeding, infection, or perforation are rare.

Results are reported by the endoscopist and may include visual findings and tissue biopsy results, which guide diagnosis and management.
