Hemorrhoids may be external or internal. If they develop inside the rectum, they are called internal hemorrhoids. External hemorrhoids develop around the anus just below the skin. Some of the external hemorrhoids develop blood clots and are quite painful. They are called thrombosed hemorrhoids. Another type of piles is so large that they often protrude during defaecation. They are called prolapsing piles.
Colonoscopy is a procedure used to view the large intestine (colon and rectum) using an instrument called a colonoscope, a flexible tube with a small camera and light source attached to its tip. Colonoscopy can be performed for screening or diagnostic purposes. While diagnostic colonoscopy is performed to confirm the presence of colorectal cancer or colorectal polyps from a person showing symptoms (blood in stools, anemia, etc.), screening colonoscopy is performed on an asymptomatic person without any prior history of the two conditions.
Sigmoidoscopy and Proctoscopy
Sigmoidoscopy and proctoscopy are diagnostic procedures performed with lighted viewing tubes called scopes introduced through the anus to inspect the lower end of the large intestine (sigmoid colon) and the rectum (just above the anus) respectively. Each procedure uses a particular scope which permits the doctor to inspect for any signs of disease or abnormalities such as tumors, polyps, ulcers, hemorrhoids, inflammation, or bleeding.
Hemorrhoids, also known as piles, are swollen or enlarged blood vessels inside or around the rectum and anus. When veins in the lining of the anus and rectum become enlarged, they are filled with excess blood and cause the underlying tissues to swell, forming abnormal lumps.
The colon is another name for the large intestine. The rectum is the lower part of the large intestine that is connected to the sigmoid colon (lowermost part of the colon). The colon and the rectum (bowel) function to store and expel processed food and waste. Colorectal surgery is the surgical removal of all or a part of the colon or the rectum.
Open Colon Resection
The colon is the large intestine. The colon and the rectum (bowel) function to store and expel digested food and waste. Colon resection or colectomy is the surgical removal of all or a part of the colon.
Robotic Colorectal Surgery
Colorectal surgery is the surgical removal of all or a part of the colon or the rectum. The colon is also known as the large intestine or large bowel. The rectum is the lower part of the large intestine that is connected to the sigmoid colon (lowermost part of the colon). The colon and the rectum function to store and expel processed food and waste.
Laparoscopic Colon Resection
Laparoscopy is a minimally-invasive surgical procedure that uses a laparoscope to diagnose and treat various disorders. A laparoscope is a thin fiber-optic device fitted with a camera and lens. Images from the camera are transmitted to a large monitor for your doctor to view the inside of your body.
Robotic Colon Resection
The colon, also called the large intestine, along with the rectum function to store and expel digested food and waste. Robotic colon resection is the surgical removal of all or a part of the colon using robotic assistance. It is usually performed using the da Vinci surgical system which consists of three components- the surgeon’s console, robotic arms, and a video tower.
