Gastroscopy — Endoscopic Diagnostics

Gastroscopy — Endoscopic Diagnostics

Gastroscopy is an endoscopic procedure for visual examination of the esophagus, stomach, and duodenum. It detects the causes of abdominal pain, digestive issues, and suspected tumors.

At Medical Time Hospital, the examination is performed with modern flexible gastroscopes supervised by experienced gastroenterologists.

During the procedure, tissue samples (biopsy) can be taken, lavage performed, and foreign bodies removed.

The examination takes 20–30 minutes under general anesthesia with continuous vital signs monitoring.

The service is available without waiting, with precise diagnostics and professional team support.
