Sigmoidoscopy is a procedure that uses a special instrument called a sigmoidoscope to examine the inside of approximately 70 cm of the gastrointestinal tract, including the anus, the rectum, and the sigmoid and descending colons.
The purpose of the examination is to morphologically assess the mucosal surface of the large intestine.
With the use of additional instruments, it is possible to collect mucosal specimens for histopathological examination and perform endoscopic examinations. The examination can be performed under general anaesthesia (the patient is put to sleep for several minutes by being administered an intravenous agent).
How to prepare for the examination:
Three days before the examination:
- light diet excluding fruits, vegetables and brown bread.
One day before the examination:
- at around 12.00 a.m., you should drink the Fortrans preparation – available on presc.ription (dissolve the contents of the 4 sachets in 4 litres of still water and then drink the prepared solution within 3-4 hours);
- at 10.00 p.m. apply the first ENEMA (to be purchased at the pharmacy without a presc.ription);
- do not have any meal in the evening.
On the day of the examination:
- on an empty stomach (refrain from eating and drinking, with the exception of your regular medications which can be swallowed by drinking 1-2 spoons of water);
- the second ENEMA should be applied 2,5 hours before the examination
Once the examination is over, Espumisan (3 x 2 tabs) or No-Spa (3 x 1 tab.) can be used to avoid any discomfort.
