Complications after a colonoscopy: abdominal pain, diarrhea, constipation, blood


Examination of the bowel in modern conditions is not such a rare procedure. This does not mean that it is recommended to go to the doctor each applied to the patient. But facts are facts. This method allows to assess the condition of the intestinal mucosa. Colonoscopy is also possible to determine the tone of the body, the presence of organic obstacles to the normal passage of intestinal contents. Usually study only accompanied by unpleasant sensations during the procedure. But failure to use proper technique study, inadequate preparation for her possible complications of colonoscopy. We would talk about it in the article.


This accumulation of gases, air in the gut. Usually there it appears in the decay and fermentation of intestinal contents. After colonoscopy bowel flatulence often develop. This is due to the flow of air during the study colonoscope.

The pain may appear at the time of the study, and after a certain time after the vote. What is it about?

  • Stretching of the bowel loops of the colonoscope at the wrong actions of the endoscopist.
  • Flatulence with plenty of air.
  • The wound of the mucosa of the colon at any segment.
  • Perforation of the intestine.
  • Stretching of the anus.
  • Ends with the action of anesthetics, so it hurts the area of the rectum.

Pain after colonoscopy is a common phenomenon. When the action component of anesthetic and sedation, you may receive pain impulses. After a colonoscopy from all the consequences of it – the most harmless. When using candles with the anesthetic component of the situation is normalized.

More serious is the situation with the perforation or wound of the mucous membrane of the colon.

If stomach pain after colonoscopy: what you need to do?

The priority should be to exclude perforation. This is the state when the integrity of the intestinal mucosa is broken, and its contents flow into the free abdominal cavity, causing at first, local irritation of the peritoneum. Then the local strange feeling transformirovalsya in diffuse peritonitis.

To avoid this complication is to carry out radiography of abdominal cavity organs. Appears shade free gas. When perforation resorting to surgical treatment. Better if access will be open.


This complication develops due to a number of factors. Often the colonoscope injure the mucous membrane. The defect may be of varying depth and extent. Depending on these factors, the degree of bleeding can range from petechiae on the intestinal wall to massive bleeding that can lead to hemorrhagic shock.

Manifestations of this complication is not always bright. You may receive the stool mixed with blood. When blood loss continues for a sufficient period of time, can increase the signs of anemia. Problems with skin, nails and hair. The patient becomes tired and lethargic. Appears tachycardia, tendency to low blood pressure.

In addition to errors on the part of the endoscopist, namely, the traumatic forces or failure to observe safety in the Genesis of hemorrhage has a value of a number of factors.

Before performing a colonoscopy, recommended the abolition of antiplatelet agents, and anticoagulants. Because this procedure is equivalent to surgery. It carries the risk of bleeding. The part and anticoagulant drugs affect the blood clotting system, strengthening the processes of «thinning» the blood. It is important for the prevention of thrombosis. But during a colonoscopy and other invasive procedures the risk of bleeding outweighs the risk of thrombosis, so you should exercise therapy «bridge» with a reduction in dose or temporary cessation of treatment.

The weakness of the capillary walls may cause profuse bleeding. During the procedure the colonoscope touches a mucous membrane. When the fragility of the vessel walls may be point bleeding, during each contact of the colonoscope with mucous membrane.

Finally, the appearance of blood could be diagnosed not only after but also during the colonoscopy. Then there is the possibility to carry out the coagulation of the damaged vessel.

How to treat bleeding? In a small volume of blood loss, you can avoid the introduction of hemostatic means. This aminocaproic acid, tranexam, menadione. If we were to lose a large amount of blood, you need to make up for lost volume with transfusion of the erythrocyte mass. Then in the stabilization of the state to resort to laparotomies intervention.

Violations of the chair

After carrying out the described diagnostic procedures may develop intestinal disorders. There are two options pathology: diarrhea (diarrhea) and constipation.

Diarrheal syndrome may occur due to the fact that increases intestinal peristalsis. This contributes to the irritation of its mucous colonoscope. During the first day after the procedure diarrhea is considered normal. But if it persists for more than 2 days, you should schedule an appointment antidiarrheal remedies.

Constipation – the second variant of violations of the chair. They may be associated with trauma to the sphincter of the rectum. The second reason – trauma of the mucosa and associated spasm. It is recommended that the inspection of the surgeon. If there are no signs of damage to the sphincter of the anus, it is possible to do conservative treatment, which includes laxatives and other medicines.

Only adequate preparation for the procedure, carefully following the instructions, the competence of the doctor guarantee a successful colonoscopy without complications and unpleasant consequences.
