Features of sigmoidoscopy
In the presence of intestinal pathologies, the correct conclusion can be made only by resorting to instrumental methods of diagnosis. One of the most popular techniques is considered to be the procedure for examining the inner surface of the intestine.
Sigmoidoscopy (rectoscopy) is an endoscopic examination of the intestine, located at a distance of up to 35 cm from the anus. A visual examination is done using a sigmoidoscope. This method is used as a mandatory element of proctological examination. For patients who have reached the age of 40, it is recommended for annual passage.
In the process of this manipulation, the following possibilities appear:
- detection of malignant neoplasms;
- assessment of the intestinal walls for their elasticity, muscle tone and features of the vascular pattern.
Even microscopic neoplasms that are not detected within the framework of other methods can be detected with its help.

Rectoromanoscope is a multifunctional and integral tool for proctological examination
Features of the sigmoidoscope
The device includes a metal tube with a diameter of 10 to 20 mm, with a built-in lighting device, an air supply mechanism and optical glasses.
In addition to examining the intestines, the instrument allows you to perform the following manipulations:
- remove foreign objects;
- take a biopsy;
- remove polyps;
- perform vascular coagulation.
Depending on the symptomatology present, rigid or flexible instrumentation is used.
Indications for the procedure
A specialist prescribes a study if the patient has the following manifestations of intestinal diseases:
- discomfort in the anal area;
- haemorrhoids;
- regular stool disorders;
- periodic constipation;
- discomfort during bowel movements;
- purulent discharge from the anus;
In the presence of inflammatory bowel processes, this manipulation is included in the list of mandatory measures.
With the help of a rectoscope, proctosigmoiditis, cracks, polyps, ulcerative colitis, benign and malignant neoplasms are detected.

Sigmoidoscopy allows you to examine the rectum and sigmoid colon
Contraindications to rectoscopy
Sigmoidoscopy is an affordable way of examining the intestines, which has practically no contraindications. Inspection is undesirable in the presence of the following processes or diseases:
- bleeding from the anus;
- mental disorders;
- acute paraproctitis;
- large anal fissures;
- heart failure;
- narrowing of the intestinal lumen;
- peritonitis.
If there is a need for an emergency examination, the procedure is performed under local anesthesia.
Preparation for rectoscopy of the intestine
Due to the fact that fecal masses make it difficult to diagnose, the intestines should be cleaned before visiting the doctor. To ensure that an accurate diagnosis is made, the proctologist recommends that the subject follow a slag-free diet for several days before the manipulation.

A reliable result can be obtained only with proper preparation for rectoscopy
Features of the menu before the procedure
Since medical nutrition is short-term, it has no contraindications. The only exception is individual intolerance to a particular product. The main principle of the diet is to avoid rough foods and focus on easily digestible foods.

Cleaning methods

After 2 hours after lunch, the patient should move on to cleansing the intestines
Fortrans
A safe product that does not affect the state of microflora and chemical processes in the body. Due to the slowing down of the process of absorption of liquid, softening and release of feces occurs.

"Fortrans" enables comfortable bowel cleansing
