Hemoclip Application & Polypectomy
An endoclip is a device made of metal that is used in medical endoscopy to close two mucosal surfaces without going for surgery. Hemoclip is a kind of endoclip that is used for ligation of small blood vessels during surgical procedures. It is made up of malleable metal. and its function is similar to that of a suture which is used to join two disjointed surfaces. It can be applied through an endoscope under direct visualization.
Endoclips come in various shapes and sizes with two or three-prong devices. Reloadable and single-use systems are used to administer these endoclips.
Endoclips are used in treating gastrointestinal bleeding of both the upper and the lower gastrointestinal tract. It is also used to prevent bleeding after therapeutic procedures such as closing gastrointestinal perforations and polypectomy.
What is Polypectomy?
Polypectomy is used to remove polyps from the inside of the large intestine or colon. It is a non-invasive procedure that is generally carried out during colonoscopy.
What is the procedure of Polypectomy?
During a colonoscopy, a long, thin, flexible tube called a colonoscope is passed through the rectum to examine the inner segments of the colon. This is generally done for middle-aged people to check for any abnormal growth, indicative of cancer. Sometimes the doctor may find an abnormal collection of tissue, called polyps, during the procedure. In such cases, the doctor may perform a polypectomy at the same time and send polyps for histopathology examination.
What are Polyps?
A Polyp is a precancerous growth, which means that it can develop into cancer if left untreated. Polyps can be categorized into four types:
- Adenomatous polyps
- Hyperplastic polyps
- Inflammatory polyps, and
- Villous adenoma.
A flat-shaped polyp is called sessile while the one having a long stalk is called pedunculated.
What are the symptoms?
Polyps do not cause any symptoms and therefore go undetected until they are found during colonoscopy or other tests related to the colon. In certain cases, the following symptoms are seen:
- Blood in the stool.
- Diarrhea or constipation
- Bleeding from the rectum.
What risk factors are associated with the formation of Polyps?
Some people are more at risk of developing polyps than others. Some of these risk factors include:
- A personal history of ovarian cancer
- A sedentary lifestyle.
- Eating a high fat diet.
- A family history of Colon cancer.
- Age above 50 years.
- History of alcohol and cigarette smoking.
Polypectomy is considered quite safe with a low rate of complications.
