How to check the colon without colonoscopy: an alternative methodology


Patients who at least once had to go through this procedure, decide to find other ways how to check the colon without colonoscopy. Sometimes even the stories have held such an examination can be very scary. Undoubtedly, this manipulation is not pleasant, but it has a number of advantages over other research methods. So, for example, the colonoscopy allows not only to evaluate the internal state of a thick intestine, but also to take samples of the material if necessary. Also, this manipulation allows for the removal of tumors discovered in the research process.

Currently developed many techniques how to examine the small intestine non-invasive ways. One of their disadvantages is the inability to produce a biopsy.

Before talking about alternatives to this method of study, it is necessary to say what is the procedure. Colonoscopy – instrumental examination of the intestine, allowing to estimate its internal structure. This study helps in the diagnosis of neoplasms of different nature, diverticulitis, inflammatory and infectious processes hemorrhoids.

Correct patient preparation for study allows you to quickly perform the procedure and obtain the correct data!

To the procedure a colonoscopy is necessary to properly prepare that it was not necessary to repeat. How to implement it, you tell the doctor who ordered a colonoscopy, but there are some General rules: uncindery diet, enema or the use of special drugs (Fortrans, for example).

So, how to check the intestines in addition to a colonoscopy:

  • Magnetic resonance imaging.
  • CT.
  • A sigmoidoscopy.
  • The barium enema.
  • Capsule study.
  • Ultrasound colonoscopy.

MRI (magnetic resonance imaging)

You need to understand that MRI cannot replace an invasive procedure. Often it serves only as an additional method. To examine the bowel in such a way as you can with the use of contrast agents, and without.

MRI also has disadvantages. In addition to the lack of the ability to take a biopsy, you need to remember that such imaging does not allow to accurately identify pathological self education can only indirectly judge about the structure of the detected lesion. A clear disadvantage is the cost of research.

Computed tomography

An additional method of diagnosis does not allow to get all the information about the state of the body. In the case of small mucosal defect computed tomography will not be able to answer the question about its structure and character.

CT was supplemented with the possibility of creating a three-dimensional structure of internal organs. This study is called virtual colonoscopy. You can say it is similar to a conventional colonoscopy. However, a complete replacement for the standard colonoscopy, it is not, as it is impossible to forget about the impossibility to obtain samples of the material.


In the course of this study is instrumental inspection of the rectum. In some sources it is possible to meet opinion that sigmoidoscopy may replace the colonoscopy. However, we must understand that this procedure visualizes the intestines only within 30 cm from the anus.

Procedure sigmoidoscopy should be done every 5 years starting from 40-45 years!

As you can see from the above, to replace the study a colonoscopy will not work. But in some situations can be limited to only sigmoidoscopy.

Barium enema

Represents the x-ray examination of the intestine using a contrast agent. To do this, use suspension of barium. Methodology of the study requires a double contrast. First – filling of the lumen of the bowel contrast agent, and subsequently inflating air. Due to this, it is possible to obtain an accurate impression of the walls of the intestine, which helps to visualize any damage to see tumors and ulcers.

An advantage of this method is its non-invasiveness. But it also lacks the possibility of obtaining material and it is not always possible to say exactly at what point on the wall of the colon is the tumor. Specialist, who examines the state of the intestine will not be able to put the correct diagnosis in a difficult case.

Capsule study

Most often, this procedure is prescribed to those patients who due to the anatomical features cannot be performed standard colonoscopy. Another way to explore the intestines. The capsule has small size, does not cause significant inconvenience to the patient when swallowing. All the time advancement of the capsule through the digestive tract, it produces images. These frames are transmitted to the recording device. After the capsule opens naturally, the resulting material is evaluated by the specialist.

Despite the apparent ease of the study, capsule colonoscopy has a significant drawback. Sometimes it is very difficult to assess the localization of tumors, especially in the sigmoid colon that has twisted the course.

We can say that capsule colonoscopy – a good alternative to a colonoscopy of the bowel. It allows you to evaluate the intestinal all the way through, unlike other methods.


Ultrasound is a rapid screening study. This examination of the colon without colonoscopy can be performed transabdominally, ie through the abdominal wall. Thanks to the capabilities of ultrasound to assess the condition of the submucosal and muscular layers of the intestinal wall. If you need to visualize the anal canal that cannot be seen through the abdominal wall, an ultrasound study can be carried out intraluminal rectal sensor.

Typically, ultrasound is appointed in the following cases:

  • If the colonoscopy showed the presence of cancer.
  • To diagnose the pathology of a thick intestine.
  • If the patient is at risk for cancer of the intestine.
  • If a person applies with clinical signs of defeat of digestive system.

Any diagnosis is based on combined data obtained from different research methods. The only way to get detailed information.

You can see that a viable alternative to colonoscopy no. Some of the above diagnostic methods can complement each other, to obtain the correct diagnosis.
