Examination of the anal canal
(protoscopy)If the lower section of the rectum and the anal area need to be examined, a rigid probe with a camera is used. This endoscope is used, for example, to clarify the presence of hemorrhoids. But it is also used for the finest cracks in the mucous membrane, so-called fissures. The method is also helpful when patients are affected by fistulas. In this case, pus ducts have formed between the anal canal and the area surrounding the anus.
Before the examination
For a better overview, the rectum must be cleared of stool before the examination. This is done using a mini-enema, a so-called clysma, or with an enema immediately before the examination.
After the examination
Discomfort in the anal area, flatulence or nausea after a protoscopy are generally harmless and disappear spontaneously. However, if you experience symptoms such as pain, fever, sweating, vomiting, vomiting blood or blood in the stool after the examination, please go to the emergency room of the hospital or your physician immediately.
