Among the frequently manifested pathological changes in the gastrointestinal organs, diagnostics began to detect such benign tumors as polyps. The structure they have is the same as the pathology in other organs.
In its structure, this formation on the mucosa of the digestive organs is a protrusion that protrudes into the cavity of the organ, which is connected to its wall by a wide base( sessile), or a thin pedicle( standing).The shape and magnitude of this may vary.
In stand-up neoplasms, the pedicle is very pronounced and sufficiently high up mushroom-shaped or spherical in structure over the surface of the mucosa. At visual inspection it is visible, that he high enough rises in a free cavity of an organ.
The sessile shape of these outgrowths is completely absent. Such formations develop directly on the organ wall and do not protrude upward. This type usually gives metastasis of malignant cells.
They also differ in the external structure of the surface, which is ulcerated, lobed, vi
llous or smooth. There can be both single outgrowths and polyps collected in the colony. In this case, the patient develops a disease such as polyposis.
Structure of polyps and the nature of their occurrence
These tumors can have a different structure. Usually its following varieties are distinguished:
- Inflammatory. This includes psevdopolopoly, which in structure exophytic outgrowths of the mucosa and are surrounded by significant erosive lesions. This structure of neoplasms is usually noted in those patients who have a history of prolonged inflammatory bowel disease;
- Lymphoid structure of the polyp. This is a type of inflammatory neoplasms in which lymphoid infiltration of the mucosa is well expressed;
- Hyperplastic polyps according to the structure. The structure of these, rather small, pathological outgrowths is usually mastoid, and the dimensions do not exceed 5 mm.
By the nature of its occurrence, these benign, though quite dangerous, neoplasms are also different. The development of them depends on the following factors:
- Disturbances in the diet, as well as the patient's admitted biases in the diet;
- Impairment of lifestyle;
- Presence of addictions;
- Frequent stressful conditions;
- Nervous and physical overwork;
- Hormonal disorders.
Depending on the nature of the polyp, as well as on the structure and size, the specialist chooses the most appropriate method of therapy in a particular case. This can be like cauterization of small-sized single neoplasms, and surgical intervention to remove large and numerous.
Blood flow in the
polyp These benign neoplasms are localized in different parts of the digestive system unequally. Most often they occur in the stomach, then in the intestines, and the rarest of their appearance is noted in the esophagus.
All of them are different in structure, shape and size. To remove these pathological changes did not cause problems in the future, it is necessary before the operation to collect the most complete information about this tumor.
Diagnose them usually with the help of ultrasound. In the event that the detected benign growth is large, it is also necessary to perform a Doppler study, which helps to determine the blood flow in it as well as in adjacent tissues.
In the case of blood flow disturbance in any polyp in structure, its color changes to dark purple, and in some cases even purple. Removal of large tumors without this additional study is unacceptable.
