A full length Colonoscopy is a medical procedure performed to view the inner lining of the rectum and the colon (large intestine). The procedure uses a long, tubular and flexible instrument inserted into the anus through the full length of the colon to check for any suspicious obstructions or growth inside.
Colonoscopy is not painful, but it may produce certain discomfort among patients as he/she may have to change positions to allow the scope advance through the colon smoothly. Small polyps found inside are usually removed with the colonoscope. If there are excessive stools or blood or secretions that obstruct viewing, they are removed with the help of the scope. Sometimes, air is pumped through the scope to clear any blockage in order to open the channel.
If there are abnormal growths, tiny brushes and forceps are put inside the colon through the anus to extract tissue samples for further examination. Once complete, the doctor withdraws the instrument slowly from the back of the patient and the anal area is cleaned. Air instilled inside during the procedure is allowed to pass out and the patient is kept under observation for sometime before he/she is released.
The common symptoms of Colonoscopy include acute persistent abdominal pain, changes in bowel habits and profuse rectal bleeding. The procedure helps to detect colorectal cancer in patients after the age of 50. Before Colonoscopy procedure, the patient has to meet certain obligations specified by the doctor.
The recovery time of Colonoscopy takes several hours. The doctor keeps the patient under observation until the effects of anaesthesia wears off. Usually, patients are discharged after some hours and they can resume normal activities and a usual diet otherwise instructed.
In most cases, many feel drowsy after the procedure. Therefore, someone should be present to drive the patient home. However, they experience considerable amount of gas passing and abdominal cramping. If polyps were removed during colonoscopy, then the patient may notice blood in their stools for a few days. In case of extreme discomfort, patients should inform the doctor right away.
