A Brief Guide About Endoscopy

What is endoscopic? (endoscopic คือ, which is the term in Thai)During an endoscopy, your doctor will use small, specialized equipment to examine and treat problems within your body’s internal organs and blood arteries. Surgeons can use it to see inside issues without making major cuts.

The surgeon makes a small incision or uses another orifice, such as the mouth, to insert the endoscope. Your doctor can see inside your body with the help of a flexible tube equipped with a camera called an endoscope. During a procedure or biopsy, your doctor can use the endoscope’s built-in forceps and scissors to remove tissue.

Why Do I Require An Endoscopy?

Endoscopy is a method used to inspect inside organs without a traditional surgical incision. The doctor can observe what the endoscope sees in real-time, thanks to a screen in the operating room.

In most cases, your doctor will use an endoscope to:

  • Determine what’s causing your unusual symptoms;
  • Do an endoscopic biopsy, in which a little piece of tissue is removed for further testing in a lab.
  • Facilitate surgical procedures requiring intraoperative visualization, such as those used to treat stomach ulcers, remove gallstones, or treat cancers

What Should I Do To Be Ready For An Endoscopy?

Your doctor will provide you with thorough pre-op instructions. If you’re getting an endoscopy, you won’t be able to eat anything solid for at least 12 hours beforehand. Up to two hours before the treatment, you may be able to drink clear drinks like water or juice. Your doctor will explain everything in greater detail.

To prepare your digestive system for surgery, your doctor may prescribe laxatives or enemas to be used the night before. This is a common complication of gastrointestinal (GI) and anus surgeries.

A thorough physical examination and discussion of your medical history, including any recent surgeries, will precede the endoscopy.

Tell your doctor about any medications you’re taking, both prescription and otherwise, including vitamins and herbal remedies. Tell your doctor if you have any known allergies. Certain medications, such as anticoagulants and antiplatelet drugs, may need to be discontinued if they impair bleeding.

Since you might be groggy from the anesthetic, you should arrange for someone else to drive you home.


Endoscopic operations are often performed through the mouth, the nares, or tiny incisions. These methods can be used to learn more about a health issue, get a proper diagnosis, or even treat it. The recovery time for these operations is short, and patients can usually go home within only a few hours. Some negative effects could be such as a sore throat or gas. However, in most cases, the situation will improve rapidly. If symptoms persist, it’s important to see a doctor.
