PREPARATION FOR GASTRIC ENDOSCOPY

PREPARATION STEPS BEFORE GASTRIC ENDOSCOPY:

You should fast for at least 6 hours before endoscopy (preferably overnight) to avoid choking on food and ensure more accurate observation and assessment of lesions during endoscopy.

Gastroscopy not only detects damage to the esophagus, stomach, and duodenum, but also screens for Helicobacter pylori infection . Therefore, you should stop taking antibiotics for at least 1 month and anti-acid drugs for at least 2 weeks before the endoscopy.

Painless gastroscopy

WHY IS GASTRIC ENDOSCOPY NEEDED?

Gastroscopy is usually indicated in all cases with symptoms of suspected upper gastrointestinal tract pathology such as: epigastric pain, nausea, dysphagia, dysphagia, indigestion, belching, heartburn, epigastric burning, reflux, anemia, unexplained weight loss, upper gastrointestinal bleeding, etc.

Diagnosing gastrointestinal diseases by endoscopy is not only highly accurate but also helps to take biopsy tissue samples from lesions or esophageal and gastric mucosa for histopathological testing in cases of suspected cancer or to help assess Helicobacter pylori infection or not, early cancer screening staining, removal of foreign bodies in the gastrointestinal tract, hemostatic injection to treat gastrointestinal bleeding, etc.

HOW IS A GASTROSCOPY USUALLY PERFORMED?

You will lie on your left side, and the health care provider will spray a numbing medicine into your throat to reduce discomfort during the procedure.

The doctor will insert the endoscope into the mouth, through the throat, to the esophagus, stomach and duodenum to observe the mucosal surface, evaluate and record lesions, and take pictures for storage.

The doctor uses disposable biopsy forceps (safe, non-infectious) to take a small sample of stomach tissue for the CLO test to detect the presence of Helicobacter pylori bacteria in the stomach.

Endoscopy time is usually 2 to 3 minutes.

PAINLESS GASTRIC ENDOSCOPY:

Painless endoscopy will bring a gentle, smooth feeling, without causing nausea or vomiting as well as the discomfort of normal endoscopy. The doctor will inject a small amount of sleeping pills and you will sleep for a few minutes during the endoscopy. After the endoscopy, you will wake up immediately, the medicine will not affect your memory.

INTERVENTIONAL ENDOSCOPY FOR EARLY CANCER DIAGNOSIS:

Methylene blue staining endoscopy in the diagnosis of early gastric cancer aims to localize the lesion, identify the characteristics of the lesion, and help clarify the boundaries of cancerous lesions. NBI endoscopic technique with narrow band light has created a breakthrough in screening and diagnosis of gastric cancer in early and very early stages, as well as other lesions.

WHEN WILL THE ENDOSCOPY RESULTS BE AVAILABLE?

Usually, the patient will have the results after 30 minutes, including the endoscopy results and CLO test (finding the stomach disease-causing bacteria Helicobacter pylori ).

In case of suspicious lesions, the endoscopist will take a sample of the lesion tissue for histopathological testing. The test results will be available after a few days or the same afternoon if you register for the urgent results service.

WHEN TO LIGATE ESOPHAGEAL VARICOSE VEINS?

Esophageal varices are abnormally enlarged veins in the lower part of the esophagus (the tube that connects the throat and stomach).

Esophageal varices are common in patients with cirrhosis.

Esophageal varices usually do not cause symptoms unless they bleed. Signs and symptoms of bleeding from esophageal varices include: Vomiting blood, passing black stools.

Indications for esophageal variceal ligation (VEL):

Grade II, III varicocele, red mark, currently no bleeding.

Prevention of gastrointestinal bleeding (GIB) due to primary or secondary esophageal varices.

Treatment:

Rubber band ligation of varicose veins causes ischemia and necrosis, thereby causing fibrosis of the vascular wall, reducing the risk of gastrointestinal bleeding due to ruptured esophageal varices.

Follow-up after esophageal variceal ligation:

- Patients need to: Eat liquid and cool foods, avoid hot foods for the first 48 hours. Avoid heavy work for 1 week. Take medication regularly as prescribed by the doctor.

- If the patient experiences one of the following symptoms: Black stools or bloody stools, vomiting blood, high fever → Call the treating physician immediately for instructions on hospitalization.
