Customer question:
How is a gastroenterological examination performed? Anonymous customer's question
Pharmacist's answer:
There are several types of gastroenterology examinations, depending on the symptoms and the suspected diseases. Before the examination, patients often consult with their doctor about the procedure, preparations, and potential risks.
Before the procedure, the doctor may also request special diets or food and fluid restrictions.
Some standard gastroenterological examinations include:
Endoscopy
- Gastroscopy (esophagogastroduodenoscopy - EGD): a procedure in which a flexible tube instrument (gastroscope) is used, which is inserted through the mouth and throat into the esophagus, stomach, and the first part of the small intestine (duodenum).
- Colonoscopy: a procedure that uses a long, flexible endoscope (colonoscope) inserted through the rectum into the large intestine to examine the inner wall of the intestine.
Capsule endoscopy
The patient swallows a small capsule containing a camera, which then passes through the digestive system and takes pictures of the inner walls of the intestine. It is mainly used to examine the small intestine.
Ultrasound of the digestive system
Used to examine abdominal organs, including the liver, gallbladder, pancreas, and stomach.
X-ray examinations
- Abdominal X-ray: helps to examine structures in the abdomen.
- Colonography with double contrast: X-ray examination of the colon after administration of a contrast medium.
Lab tests
These may include tests of the liver, pancreas, and other parameters that help assess the function of the digestive system.
Biopsy
During an endoscopy or other procedure, the doctor may take a small tissue sample (biopsy) for further laboratory analysis.
