What is flexible rectosigmoidoscopy?
Flexible rectosigmoidoscopy represents an examination of the lower part of the large intestine (sigmoid colon and rectum) by a sigmoidoscope, a flexible optical instrument that is approximately 50cm long. The sigmoidoscope emits a cold light which enables an overview of all anatomic structures of the descending colon, but also shows the pathological changes in the intestine itself, such as tumors, bleeding, diverticula.
When is a rectosigmoidoscopy performed?
A rectosigmoidoscopy is performed when a patient bleeds from the large intestine, that is, when there is blood or mucus in the stool, when he/she experiences pain in the anus or the large intestine area caused by often constipation that last for several days, as well as due to the occurrence of diarrhea with mucus. The examination itself could be slightly uncomfortable, or could cause bloating (because of the pushing of air into the large intestine) or pain in the area of the large intestine or abdomen.
How to prepare for the examination?
One must be on a light diet two days before the examination, and can only consume liquid or mushy food the day before the procedure. Do not have dinner. Buy 6 suppositories such as Panlax, Glicerol or Dulcolax. The day before the examination, at 6pm, put 2 suppositories deep into the anus, and empty your bowels a half an hour after that. Repeat this procedure at 10pm and 10am on the day of the examination. Do not consummate food and drinks on the day of the procedure.
