Biopsy of a large intestine
Contents:
Description:
The biopsy of a large intestine represents an intake of its fabrics or cells for the purpose of the subsequent their gistomorfologichesky research. Receive fragments mucous or a blind aspiration method, or withdraw precisely in the course of performing endoscopy (rektoromano-, kolonoskopiya) or anoskopiya.
Indications to a biopsy of a large intestine:
Indications in both specified cases will be various: the first option is applied only in need of verification of any diffusion defeats of a gut, and the second, in addition, is used at suspicion of a tumor, tuberculosis, a disease Krone.
Technology of carrying out biopsy of a large intestine:
The morphological research of a bioptat can be conducted by means of the light microscopy giving an opportunity and just routine way to study histology, and to apply histochemical processing of material. Also more difficult stereoscopic technique allowing to see drug in three dimensions is used, providing feeling of dimensions. Ultrastructural changes of a mucous gut are estimated by means of a submicroscopy.
Intravital morphological studying patholologically of the changed tissues of a large intestine in most cases is decisive a stage of diagnosis of the main nosological forms and allows to resolve many controversial clinical issues. Of course, first of all, the biopsy is extremely important for exact recognition of the nature of new growths. Thanks to what it is possible to avoid not repaid operative measures when they either are not shown at all, or have to have absolutely other focus. At a histologic research of bioptat of tumoral fabric define cellular structure and degree of a differentiation of its elements, and then, being based on the obtained data, develop tactics of treatment of the patient.
The method gives help and in recognition of inflammatory and even functional diseases of a large intestine. In the first case degree of manifestation and a phase of pathological process in an intestinal wall is objectively estimated and control over efficiency of the carried-out therapy is exercised. In the second – the organic reasons of the available clinical symptoms are excluded.
The intake of fabrics from distal departments of a large intestine for carrying out microscopy usually is made during execution of a rektoromanoskopiya, and of proximal – during a kolonoskopiya the tools entering endoscopic koloproktologichesky set.
For a biopsy usually choose those sites which or act in a gut gleam, or in any other manner differ from normal fabric. There are situations when important to receive fabric on border of the center of defeat and externally not changed mucous membrane (for example, when studying a malignant tumor). The received pieces fix in 10% solution of neutral formalin and already then carry out diagnostic manipulations.
The biopsy of a large intestine can be executed during a videokolonoskopiya
Complications after a biopsy of a large intestine:
As a rule, no complications neither during a biopsy, nor after it happen. But, those not less, it is the surgical procedure demanding extremely accurate performance the result of all research in many respects depends on correctness of an intake of material.
