Rectoscopy is one of the methods that has an important place for early diagnosis of diseases of the last part of the large intestine. Rectoscopy in the human body has a highly effective place in examining the lower part of the digestive system. However, although it is used a lot today, many people do not have detailed information about this extremely important method.


Rectoscopy, which is used to examine the lower part of the digestive system, known as recto-sigmoidoscopy in medical language, is actually an endoscopic imaging method. The last part of the digestive system and large intestine is called the rectum. The rectum is 12 to 15 cm long and connects the large intestine to the anus. With rectoscopy, a type of endoscopic imaging method, the rectum can be examined in detail.

In this way, problems in the rectum are easily detected. In this procedure, a piece of tissue can be taken from the area if necessary, in addition to imaging. The existing disease can be diagnosed by pathological examination.

Rectoscopy is an application that allows visual examination of the last part of the large intestine by means of a lighted instrument, and before performing this application, the patient should go to the hospital hungry and the intestines should be examined. When such procedures are to be performed, sedation is applied and thus a painful application is not experienced. The patient is placed on a special examination table and the application is completed within 5 minutes. During this application, a biopsy can be taken for suspicions such as tumours, ulcers, and tumours.

In addition, if the lesions in the rectum are suspected, a piece is taken and examined pathologically. In this way, with the definitive diagnosis, the general condition of the patient and the treatment method to be applied can be determined much better.
