The use of the forceps biopsy has not solved many diagnostic problems of early forms of cancer, and the rate of pseudonegative findings may reach 18 to 60%. The endoscopic biopsy carried out by means of the diathermic loop is free of many drawbacks of the forceps biopsy, as the loop captures a portion of the mucous membrane and submucous layer of the gastrointestinal organs within the diameter of 20--25 mm. Clinical experience with 53 examinations has proved a high diagnostic effectiveness of the method and the necessity of its broad clinical use.
