Colonoscopy prep when does diarrhea stop : Sigmoidoscopy is called when only the colon region called sigma is explored, which corresponds to the area closest to the rectum. And it’s called rectoscopy if you only explore the rectum area, often with a rigid rectoscope. In addition to obtaining the images it also allows the performance of the other procedures, discussed above.

Colonoscopy in any of its variants requires adequate patient preparation, which must collaborate to the fullest, once it has been correctly informed about the usefulness and diagnostic profitability of the technique.

It is essential that at the time of the examination the patient has his large intestine completely cleansed of faecal residue. Otherwise the correct observation of the intestinal mucosa and even the passage of the colonoscope is prevented. To do this, during the hours before the examination the patient should take a laxative preparation every half hour for four hours, which will cause a painless watery diarrhoea until the complete emptying of the intestine. The patient should not eat solid food from six o’clock in the afternoon of the day before the test, although he or she may drink as much water as he wants.

The scan takes approximately 15-20 minutes. The patient lies on his back on the stretcher and the colonoscope is inserted into the anus, slowly advancing to observe the entire large intestine through the chamber. This procedure does not cause discomfort to the patient, who practically does not perceive the movements of the colonoscope. If it is necessary to better observe a specific area of the colon, it is necessary to introduce a small amount of air, which is noted by the patient as a pain type of retortijon, of low intensity and duration. The patient is usually warned of this perfectly. In general, the patient also does not notice the small therapeutic maneuvers that may have to be performed in the course of the examination, such as removing polyps or taking biopsies of the lesions for study. After the scan, the patient can live a completely normal life immediately afterwards.

What is colonoscopy for?

Indications of colonoscopy include:

– The study of a patient with clinical manifestations of colon disease

– Biopsy taking for the study of colon lesions previously diagnosed by another scan such as the opaque enema

– Diagnosis and control of the evolution of inflammatory diseases of the colon

– Monitoring of evolution after surgical intervention of cancerous or precancerous lesions

– Early detection of colon cancer in a high-risk population.

Sigmoidoscopy

Sigmoidoscopy is a variant of colonoscopy, which allows the area of the colon closest to the rectum, called sigma, to be explored. A rigid endoscope about 25 centimeters long is often used to explore about 50 centimeters of colon from the anus. It is a less annoying technique than colonoscopy and patient preparation only requires the administration of two cleaning enemas, at twelve o’clock and at two hours before the scan.

Rectoscopy

Rectoscopy is another variant of colonoscopy when you want to explore only the rectum area. It is made with a rigid endoscope about 10 centimeters long that allows to explore about 12-15 centimeters of the rectum, from the anus. It is also a simple, well-tolerated, fast and reliable technique, and requires patient preparation similar to sigmoidoscopy.
