Polyps, polyposis

Polyps, polyposis is a collective term for tissue formation of different origin observed (often) on mucous membranes; these formations are related to the mucous membrane broad base or a leg, in which are the blood and lymphatic vessels; they have a different shape (pear, mushroom), size, density, and there are single (polyps) or multiple (polyposis).
In the basis of these groups can be organized part of the placenta (see Placental polyp), granulation tissue (see) in chronic inflammation and regeneration (granulation polyps), malformation of the mucous membrane or benign tumors (polypous adenoma, fibroma, lipoma, angioma and so on). Most often polyps see in the gastrointestinal tract, uterus, nasal cavity, larynx, bronchi. They grow into the lumen of the data of hollow organs. Leg polyp can have different lengths and sometimes drawn in the form of a long cord, the body of the polyp is far from the base.
The polyps may experience bleeding, swelling, inflammatory changes. When twisting legs polyp may his torpor, sometimes spontaneous rejection. Polypous adenomas of the stomach, intestines, uterus considered as precancerous conditions, as they often turn into cancer.
Polyposis mainly observed in the gastrointestinal tract, representing mostly malformation of the mucous membrane, and is sometimes hereditary disease (congenital multiple family polyposis).
Clinical course mainly depends on the localization of the polyp (see the article by name of individual organs), and the magnitude and structure of the secondary changes. In some cases polyps are asymptomatic, as an incidental finding at autopsy, others bleed, narrow, and sometimes close clearance authority (polyps of the colon, stomach, bronchus and others).
For the diagnosis of polyps apply various methods of investigation - x-ray examinations, gastrostomy, a sigmoidoscopy, bronchoscopy , etc.
The surgical treatment, sometimes excised only polyp, in other cases produce resection or total removal of the body that reported the polyp.

Polyps, polyposis (gr. polypous - polyp, literally "multilegged").
Polyps - tissue growths protruding above the surface of the body and the associated long or short peduncle.
Origin, structure and fabric composition polyps heterogeneous. For example, placental polyps (see) is called the remains of the placenta, partially or completely necrotic organized and speakers in the uterine cavity above the surface of the mucous membrane. Heart polyps - sites of swollen or modified fibrous tissue, sitting on the endocardium the Atria (usually the left); their origin is unclear.
Most often polyps are located on the mucous membranes that can have different structure and consist of ferrous, fibrous, fibrous or vascular smooth muscle tissue. Chronic inflammation of the mucous membranes (the middle ear, nose and paranasal cavities, urogenital organs and others) growth of granulation tissue can take a nature polyps (granulation polyps). However, chronic inflammation may be accompanied by proliferative processes in the mucous membrane, which character of glandular polyps, and in the genitals and anus - character pointed or wide condylomas.
Leg polyp, linking it to the base, has a different length. It can stretch out in the form of long cord, which are the blood and lymphatic vessels, and the body of a polyp in this case hangs in the cavity of the body far from its Foundation.
In other cases leg is very short and the body of the polyp is directly related to its base. The longest leg of the polyp contributes to its mobility. Possible torsion legs with impaired blood flow, followed by necrosis of the polyp and his or rejection, or rotting decay and reactive inflammation.
Eating disorders polyp often cause ulceration, bleeding and reactive inflammation.
Most often glandular or adenomatous, polyps. They consist of glandular tissue with the phenomenon of structural atypism inherent adenoma (see).
Such polyps are most often found on the mucous membrane of the nose and paranasal cavity, larynx, trachea, gastrointestinal tract (all departments)of the uterus. Sometimes they are plural, and in these cases, talk about polyposis of the mucous membrane of the relevant body. Typical places of formation of multiple polyps are the stomach, small and large intestine. In the diseased intestine polyposis sometimes have hundreds of adenomatous polyps of different size.
Reasons education adenomatous polyps diverse. They can be, in particular, the consequence of regenerative (see Regeneration) processes (superregenerative) in healing ulcers of the mucous membrane (for example, in ulcerative colitis dysenteric origin). In atrophic processes in mucous membrane (for example, stomach) they are the manifestation of the vicar of regeneration taking atypical nature. On the role of chronic inflammation - see above. Sometimes the distinct role of chronic irritation (such as polyps larynx, in speakers, singers), hormonal effects on the mucous membranes (for example, cancer) restructuring it. All these reasons are private stimulating agents tumor growth, General regularities of which (see Tumors) are the basis for development of the glandular polyps and polyposis.
The clinical significance of polyps is determined by several factors: by stenosis of the lumen of the authority and a violation of its terrain (for example, nasal passages, intestines, and so on); dysmotility bodies in the intestine may lead to intussusception; ulceration with inflammatory reaction and bleeding, the repetition of which can lead to significant secondary anemia; malignancy.
In this respect, particular threat is polyposis of the gastrointestinal tract, where each polyp is considered precancerous process.
Treatment of polyps surgery; diathermocoagulation.
Polyps separate bodies - see the Stomach, Intestines, Uterus, Nose, etc.
