Endoscopy is the process of introducing a long, thin tube into the body to closely inspect an internal organ or tissue. Additionally, it can be of use for basic surgery and other treatments. An endoscope is in use during the endoscopic treatment to view inside an organ or other hollow body cavity. During an endoscopy, the doctor puts an endoscope into the patient's body. At the ends of short tubes, it has tiny cameras and powerful lighting. Depending on the part of the body the doctor needs to see, the endoscope's length and flexibility will change. Doctors insert the endoscopes right into the organ during many other medical imaging procedures.
When there are symptoms that suggest cancer, it is in use during biopsies to diagnose cancer. It might be of use to look for signs including bleeding, inflammation, vomiting, and other things. Additionally, it is in use for medical procedures such as cauterizing a bleeding vessel, expanding a narrow esophagus, removing a polyp, or clipping off a foreign object.

When do we do an endoscopy?

An endoscopy can aid in the early detection of cancer in many body regions. On the other hand, it does not aid in treating cancer. Several conditions, including the following, may require an endoscopy:
Prevention and early cancer detection: Doctors do a biopsy during an endoscopy to assist the diagnosis of cancer or another condition.
To determine the origin of symptoms: An endoscope can be of use to find the cause of symptoms like vomiting, stomach pain, breathing issues, stomach ulcers, difficulty swallowing, or gastrointestinal bleeding.
For help with treatment: During various operations, doctors employ endoscopes. When used to remove a polyp or cauterize (heat-seal) a bleeding vessel, an endoscope can directly treat a problem.

Sometimes an endoscopy is in use with another procedure, such an ultrasound scan. It can be in use to place the ultrasonic probe close to difficult-to-scan organs, such as the pancreas.
There are certain modern endoscopes that have sensitive lights for narrow-band imaging. Certain blue and green wavelengths are of use in this imaging technique, which makes it simpler for doctors to spot precancerous conditions. Since the patient must be sedated, local anesthetic is in use throughout the surgery.

Surgical assistance

Thanks to improvements in endoscopy, a tailored endoscope can now be of use for a variety of surgical procedures. The process is consequently less invasive. Keyhole surgery utilizes a laparoscope, a modified endoscope (also referred to as laparoscopic surgery).
This approach to surgery provides for significantly faster recovery times and less blood loss than traditional surgical techniques.

Upper endoscopy

The treatment known as endoscopic gastroduodenoscopy (EGD) is an upper endoscopy that aids in the detection of most stomach malignancies. The doctor doing the test uses a narrow, illuminated tube known as an endoscope to peer inside your stomach. The medical professional pushes it down your throat and into your stomach. For this exam, you're under anesthesia. Your esophagus and a portion of your duodenum, which is the first part of your small intestine, are also under examination during an upper endoscopy. When examining aberrant tissue, a small sample is in use to test for cancer cells. A biopsy is what we term this specimen. The material is under examination under a microscope by a pathologist.

How does it work?

The physician performs an upper endoscopy using an endoscope. A flexible, thin tube with a light and a tiny camera on the end is an endoscope. The physician inserts it into the patient's mouth, throat, and esophagus. To check for tumors or other health issues, the doctor looks at the images on a screen.
The physician can remove tissue samples during an upper endoscopy by passing instruments through a passage in the endoscope. The samples are under examination in a microscope.

Diagnosing Stomach Cancer with upper endoscopy

Today, doctors view upper endoscopy as the gold standard test for detecting stomach cancer.
During upper endoscopy,

• Patients undergo general anesthesia prior to upper endoscopy procedures, which puts them to sleep and blocks off pain.
• A tube with a camera on the end is passed through the mouth, esophagus, and stomach by a doctor.
• A doctor carefully examines any abnormal regions that may be cancer as the scope advances down the esophageal and stomach walls.

Why is it the most effective option?

It might be challenging to distinguish between malignant lesions and healthy or damaged stomach tissue, even using an endoscope. The intricacies of extremely early stomach cancer can be more easily detected by doctors with significant expertise using this screening method. Recent developments in endoscopic technology, such as high-quality images and dyes, have made it possible for doctors to identify cancer at even earlier stages.

People can receive a diagnosis and treatment early because of the advancement of advanced technology and skilled medical professionals. Additionally, the likelihood of a positive outcome increases the earlier cancer is treated.

Conclusion

As was already established, endoscopy is more of a diagnostic tool than a therapeutic instrument. Endoscopy can therefore aid in the detection of cancer and perhaps even make surgery easier. Even with an endoscope, it could be difficult to tell the difference between cancerous tumors and healthy or damaged stomach tissue. This screening procedure makes it easier for doctors with substantial experience to identify the subtleties of very early cancer.
With the help of recent advancements in endoscopic technology including high-quality images and dyes, doctors are now able to detect cancer at even earlier stages. The development of cutting-edge technology and trained medical personnel allows people to receive a diagnosis and treatment at an early stage. Additionally, the earlier cancer is treated, the higher the likelihood of a successful outcome.
