Pediatric gastric and colonic mucosal biopsy
Endoscopic biopsy in children is a painless method of obtaining a small sample of tissue during gastroscopy or colonoscopy. The procedure helps identify the causes of chronic diseases, inflammation, digestive disorders, and other pathologies.

Preparation depends on the type of examination. Before gastroscopy, the child should not eat for at least 11-12 hours before the procedure so that the digestive tract is empty. Before a colonoscopy, the intestines must be cleansed with medication or an enema (as medically recommended based on the child's age), and a special low-residue diet must be followed. The procedure is performed under sedation to ensure the child's comfort and safety.
A biopsy is performed during an endoscopic examination. The specialist inserts a flexible, thin endoscope with a camera and takes several small samples of the mucous membrane from different parts of the gastrointestinal tract. The material is collected using a thin instrument passed through the endoscope channel under video camera control. The procedure takes 10 to 20 minutes.
Endoscopic biopsies at Olymp Clinic are performed using high-quality disposable instruments from leading manufacturers. Thin endoscopes equipped with HD optics and enhanced imaging capabilities make the procedure suitable even for the youngest patients.
The child recovers for 30-40 minutes under medical supervision in a comfortable ward after the procedure. Once the child is fully awake, they get personalized recommendations on their future routine and diet. We suggest avoiding active games, sports, and long trips on the day of the procedure.

Pediatric gastroscopy
Gastroscopy is a safe procedure during which the esophagus, stomach, and initial section of the small intestine are carefully examined using a thin, flexible device called a gastroscope.
Pediatric colonoscopy
Colonoscopy is an examination which involves using special equipment to visually inspect the inner surface of the large intestine and the terminal ileum. The procedure helps identify inflammation, ulcers, polyps, and other changes that may cause abdominal pain, blood in the stool, constipation, or diarrhea. If the child has a polyp, a biopsy will be performed for histological examination. Then, the need for endoscopic removal will be determined.
