Colonoscopy vs Flexible Rectosigmoidoscopy: What is the difference?


Very important in the diagnosis of colon and rectum diseases, colonoscopy and rectosigmoidoscopy are very similar exams, but with details that differentiate its recommendation.

Because they are specialized exams, they should be performed at trusted clinics, ensuring patient safety and privacy. At Colono you have specialists trained to perform the procedure within all safety standards, with the commitment of a reliable diagnosis. Now, check out the main differences between colonoscopy and sigmoidoscopy and schedule your procedure with us.

How Colonoscopy Works

One of the most requested tests by proctologists and gastroenterologists, colonoscopy helps in the investigation of diseases that affect the intestinal tract. The procedure works by introducing a flexible tube through the anus, which captures images of the interior of the intestine with high resolution and quality. In addition, the device also assists in performing biopsies, cauterizations and the removal of polyps.

Colonoscopy is essential for the diagnosis of colon and rectal cancer, as well as other abdominal and intestinal diseases, such as persistent diarrhea, anemia, chronic abdominal pain, and intestinal bleeding. For this, the patient remains sedated in most cases, and can return to normal activities the next day.

Among the advantages of colonoscopy is the possibility of a detailed analysis with enlarged images. This contributes to the recommendation of the most appropriate treatment for each case.

How Rectosigmoidoscopy Works

This procedure assists in the diagnosis of diseases that affect the final segments of the digestive tract and is performed with the same flexible device used in colonoscopy exams.

The major difference between rectosigmoidoscopy and colonoscopy is the scope of the procedure. Although not evaluating the entire large intestine, rectosigmoidoscopy is sufficient and adequate in a number of cases, particularly in the investigation of perceived bleeding from bowel movements in young and low risk patients for colorectal cancer.

Rectosigmoidoscopy does not require sedation, withdrawal from work for a full day, or a complete bowel preparation, like colonoscopy does. Its preparation can be performed a few hours before the exam and the patient can return to normal activities soon after. The duration of the exam is faster and the patient may appear unaccompanied to the clinic.

At Colono Clinic, it is possible to schedule both exams: colonoscopy and rectosigmoidoscopy. Both are performed by our experts with flexible equipment automatically decontaminated at a high level.

In the case of colonoscopy, because it is an exam that requires complete bowel preparation and sedation, it is necessary to schedule a consult before the exam. In this appointment, you will meet the doctor who will perform your exam, who will ask you for details of your history, such as medicines you use, health problems and allergies. You will leave this appointment with the exam scheduled and written and detailed information about the preparation you must do. You will also have the phone of the specialist responsible for your exam, in case you have any doubts.

In the case of flexible rectosigmoidoscopy, the scheduling can be done right now, through our online scheduling tool.
