The clinical picture of echinococcosis
Helminthiases / / May 02, 2016
clinical picture echinococcosis liver diverse and largely depends on the development phase of the parasite, as, indeed, and a number of other factors: the nature of the non-specific reaction of the human body on the developing hexacanth, rapid growth of hydatid bubble, the number of the latter, their size changesoccurring in the affected organ complications arising from both parasitic cysts and the body of the patient.
In most cases, the disease develops for several years, sometimes decades, due to the fact that the echinococcus bubble growth is extremely slow.Only in rare cases, a rapid development of the latter.Patients may not be aware for many years that they are carriers of echinococcus.This fact should be explained by the fact that hydatid disease is much more common in middle-aged men, although infection usually occurs in childhood or adolescence.
From a clinical point of view within the liver echinococcosis useful to distinguish three stages, although it should be stressed that the selection o
first stage - since entering hexacanth the liver before the first clinical manifestations of the disease.The duration of its various, sometimes several years.Cyst in the liver in a period is thicker and has a small size, so it is usually not reveal possible.The patients were not significantly disturbed, they do not complain.The disease is hidden and revealed usually accidental - if the patient study or for another reason during operation undertaken in connection with any other disease.
The second stage is characterized by different symptoms of the disease.Their appearance is usually due to the fact that the cyst has reached a fairly considerable size, or there is a rapid increase in its accompanied by tension and sometimes stretching of the capsule.Patients say stupid or more intense pain, feeling of heaviness, pressure, tightness in the right upper quadrant, epigastric or lower part of the chest.This is often accompanied by weakness, malaise, poor appetite, fatigue, with or without weight loss, shortness of breath.Occasionally allergic reactions in the form of a recurring urticaria, diarrhea, nausea, vomiting.
An objective examination revealed an enlarged liver, often right of its departments, with multiple cysts - all body sizes.When parasitic cysts localization anteroinferior surface of the liver can be determined by the visible protrusion of the anterior abdominal wall, while its lateral location - deformation of the ribs and rib arch-like hump.Enlarged liver palpation dense.On its surface may be palpable protrusion having a smooth surface and a hemispherical shape, usually plotnoelasticheskoy consistency or density of woody (with calcified cyst wall).
Less defined symptom fluctuations.Palpation is usually painless, but pain can be expressed with festering cysts or inflammation of the tissue around it.In some cases, effleurage on the location of the cyst area detected symptom "gidatid shake" typical for echinococcosis.In order to identify it in the area of "tumor" to put II, III and IV fingers of his left hand.In short effleurage strokes on the average of these extreme fingers feel a kind of vibration such as shaking jelly, which is caused by movement of daughter bubbles floating in the cyst cavity.
In the third stage symptoms occur due to various complications echinococcosis.They can develop as a result of changes taking place not only in the parasitic cyst (abscess, perforation, calcification), but also in the affected organ or body of the patient as a whole.Examples of such complications are the appearance of ascites at progressively increasing compression of the inferior vena cava cyst or jaundice due to obstruction of intra- and extrahepatic bile ducts.
It should be emphasized that such a sequence of onset of symptoms in the clinical course of the disease is observed not always.In some cases, the first manifestation of the disease may coincide with the perforation echinococcus bubble and the evolution of the severe complications.Thus, immediately after the first comes the third stage of the disease.
most common complications encountered among echinococcosis hydatid cyst abscess (15-34%).Patients suddenly appear severe pain in the swelling, the latter increases, it becomes more tense, sharply painful to palpation.The temperature rises to 40-41 ° C and takes the hectic nature.Rapidly growing phenomena of intoxication, accompanied by shaking chills and drenching sweat.In the future may develop septic condition.It is also possible breakthrough abscess into the pleural or peritoneal cavity, retroperitoneal and perirenal fat.In more rare cases, festering cyst is emptied out or in one of the neighboring hollow organs (stomach, intestine, bronchus).

extremely serious complication is the severance of uninfected liver hydatid cysts, occurring in 6-9% of cases.This usually occurs at high superficial bladder with thinned walls.Often the cyst rupture contributes to easy injury.cyst rupture can occur during medical examination - with abdominal palpation, gynecological examination.In these cases, the contents of the cyst, together with its subsidiaries bubbles poured into the abdominal cavity, causing local spread of echinococcosis.This complication was associated with the development collaptoid state and a rapid decrease in the size of palpable "tumors", sometimes the latter ceases to be determined.Often in these cases, there are painful hives and even anaphylactic shock.In milder cases, it is limited to the appearance of the rash and itching.
also possible breakthrough and emptying of hydatid cysts in the gall bladder, intrahepatic bile ducts, stomach or intestine, and the localization of it on the diaphragmatic surface of the liver - in the pleural cavity, lung, bronchus.In the first case, at the same time develop a severe attack of pain as in cholelithiasis, cholangitis and jaundice, the latter - a bad cough with sputum containing hydatid bladders, torn cuticular membrane, purulent pleurisy.A break in the gastrointestinal tract of the elements of hydatid cysts are found in the stool.
