Actually, the rectum is a straight segment of large intestine. Combined with the flexible endoscope and the experience of the doctor, patients often feel a slight tightness in the lower abdomen during anorectal endoscopy and a feeling of having a bridge. But most patients can tolerate the entire colonoscopy because the endoscope inserted into the anus is only about 15 to 20cm. However, pain threshold is different for each person.
Hence some people have a lower tolerance to pain. In these people, in order to not feel pain during anorectal endoscopy, the doctor will pre-anesthetize the patient before the colonoscopy. During the endoscopy, the patient will sleep and not always feel pain.
This is an easy-to-implement, low-cost technique that offers accurate diagnosis, high intervention capacity and less discomfort for the patient.
