history colonoscopy

colon study presents certain difficulties due to the anatomical location of the body.Previously used for this purpose x-ray, with which it was not possible to diagnose serious diseases such as polyps and colon cancer.Hard rektosigmoidoskopy used for inspection of the intestine through the anus, allowed to investigate o

nly 30 cm intestine.

In 1964 - 1965, the first flexible fibrocolonoscopy, and was invented by model colonoscope in 1966 were created, which became the prototype of the modern devices, with the possibility of photographing the structures under study and sampling of material for histological examination.

What applies colonoscopy

Until now, this type of diagnosis is the most reliable in determining the status and colon diseases.In addition to visual inspection, diagnostic colonoscopy allows tissue biopsy and remove polyps from the colon wall.

fibrocolonoscopy or optical probe is a thin, soft and flexible instrument that allows the passage of all the natural anatomy of the intestine bends without the risk of trauma and pain for the patient.the device length is 160 cm. At the end of the probe has minikamera transmitting the image on the screen with multiple images increases.The probe is equipped with a cold light source that eliminates the possibility of intestinal mucosa burns.

procedure can be carried out under local or general anesthesia and under sedation.

  • Local anesthesia - usually offered local anesthesia with the use of one of the drugs on the basis of lidocaine: Luan gel dikainovaya ointment Xylocaine gel, etc. When applied on mucous and lubricate the drug tip of the colonoscope reached a local anesthetic effect, at the same time.the patient remains fully conscious.Local anesthesia can be achieved, and intravenous administration of the anesthetic.
  • Sedation - the second option, in which a person is in a state similar to sleep, does not feel pain or discomfort, but consciousness is not off.Drugs used midazolam, propofol, and others.
  • General anesthesia involves injecting drugs, embedding patient into a deep sleep with a complete shutdown of the patient unconscious.Although the level of development of medicine, general anesthesia carries some risks, contraindications, and requires a certain time for patient recovery.Colonoscopy under general anesthesia is indicated for examination of children under 12 years of age, patients with mental illness, people with high pain threshold and in some other cases.

After anesthesia, the doctor inserts a colonoscope into the anus and consistently inspecting the wall of the large intestine, propelling the probe forward and palpation over the surface of the stomach tube on monitoring the promotion of intestinal bends.To picture was objective, intestines expands using supply air.

air Contact accompanied by bloating and discomfort for the patient, plus everything in the study can not make any movements, which is why patients prefer general anesthesia or sedation in the study period.

procedure lasts 15-30 minutes.It is promotion video colonoscope through the intestine.If necessary, a biopsy of tissue is taken, removed polyps.At the end of the study through a special channel colonoscope gas is removed and the probe gently removed from the intestine.

After the procedure, the doctor prepares a survey report, makes recommendations to the patient and sends it to a specialist.

If local anesthesia was, immediately after the procedure you can go home.General anesthesia requires observation for a certain time until the patient wakes up completely.

After the examination, you can eat and drink.If overcrowding is stored intestinal gases can take 10 tablets comminuted activated charcoal and wash it down with water.Also help massage the abdomen.

Possible complications of colonoscopy

  • perforation of the intestinal wall (frequency 1%);
  • flatulence, which runs independently;
  • bleeding in the gut (0.1%);
  • Respiratory arrest during general anesthesia (0.5%);
  • abdominal pain and pyrexia to 37.5 C for 2-3 days, if carried out removal of polyps.

  • nature of the surface - surface should be smooth and slightly striated, without ulcerations, tubercles and protrusions.
  • vascular drawing - should be uniform, without areas of gain or absence of blood vessels.
  • Overlays mucosa - associated with accumulations of mucus and have a view of the bright clumps, unsealed, impurities fibrin, pus or necrotic masses.

Any deviation from the rules described embodiments indicate a specific disease.

  • Acute myocardial infarction - acute ischemia of the heart muscle, threatening death.
  • Perforation of the intestinal wall - a condition accompanied by internal bleeding and requires emergency surgery.
  • Severe ulcerative and ischemic colitis, in which the possible perforation of the bowel during the procedure.
  • Pregnancy - the procedure can lead to premature birth.
