What is flexible sigmoidoscopy?
Flexible sigmoidoscopy is a medical procedure that includes sending a small camera connected to a special tube up through the rectum to the rectum and the lower colon to seek possible abnormalities. It can be used as a diagnostic test if someone has symptoms of possible gastrointestinal problems or as a screening test for colon cancer. Patients often have to follow certain instructions to prepare for flexible sigmoidoscopy. Generally, the procedure itself takes only a short time and can be performed in a hospital or other medical facility on an out-pacific basis. Flexible sigmoidoscopy can look at the inner part of this part of the large intestine, as well as the rectum and rectum, via a small video camera connected to the upper part of the long thin tube, which in turn is connected to the video monitor. The tube is inserted through the rectum and Air is pumped to help extend the large intestine for optimal viewing. The tube is also connected to a small cutting tool that ktErý allows the healthcare provider to take tissue samples from the inside of the large intestine and rectum.
people can undergo flexible sigmoidoscopy if they have digestive symptoms that indicate a possible problem in the lower colon. Such symptoms may include recurring constipation or diarrhea, stomach pain and rectal bleeding. Tissue samples can be removed for testing infections during the procedure. The test can also be used to help screening for colon cancer, which is generally recommended for most adults over 50 years of age, as it allows health care providers to view polyps and other potentially cancer or precancerous lesions inside the lower intestine. If such areas are visible, tissue samples can be removed for further testing.
you want to prepare for flexible sigmoidoscopy, the patient is usually served by enemahours before the start of the procedure. The enema helps to wash out any faecal material from the lower intestine. In some cases, patients may have to quickly and/or take laxatives starting a few days before the procedure to help clean the full intestine, not just the lower part.
flexible sigmoidoscopy is usually performed in a hospital or other medical facility. In general, this is a relatively short procedure, usually taking about 15-20 minutes from the time the range is inserted until it is removed. However, patients may have to be in the facility for a longer period of time to complete any preparatory steps and are briefly monitored after the procedure is completed.
In general, patients are not administered sedation, so they can return to their usual activities shortly after the procedure. Possible short -term side effects may include cramps and gas due to air pumped into the intestine or small amounat from rectal bleeding if any biopsy has been taken. Complications of flexible sigmoidoscopy are rare but may include perforACI colon. It may be a state of life threatening and usually requires repair of surgery.
