The article was consulted by Specialist doctor Pham Trung Kien – Head of Functional Exploration Department, Thai Nguyen International Hospital.

Painless gastrointestinal endoscopy is an endoscopic technique that is performed while the patient is sedated. The technique is performed in a short time, the patient is comfortable and there is no pain, vomiting or any danger.

  1. What is gastrointestinal endoscopy?

Gastrointestinal endoscopy is a method of direct examination of the digestive system. To perform this technique, doctors insert a flexible endoscope with a camera on it to look into the patient’s digestive tract. The endoscope will be inserted either from the nose/throat (upper gastrointestinal endoscopy) or through the anus (lower gastrointestinal endoscopy). From there, the doctors will observe the lesions on the surface of the digestive tract such as: esophagus, stomach, duodenum, and colon.

This method helps doctors to diagnose most of the lesions and diseases on the digestive tract such as: inflammation, ulcers, damage of blood vessels, more seriously is cancer… If there are any abnormal signs, a biopsy may be performed to determine if cancer cells are present. In addition, interventional procedures such as: removing foreign body, cutting polyps, hemostasis of ulcers, sclerotherapy, dilatation, endoscopic ligation of esophageal varices… are more convenient and safe. This is also an early and effective method of diagnosing digestive cancer.
