Rev Chil Cir ; 54 2: Within endemic zones, the prevalence varies from sporadic to high, with recent studies showing an higher prevalence among females and with increasing age[ 8 ]. Maintenance of eradication is secured through the continuous surveillance monitoring of human, canine and livestock populations.

Bile leaks following surgery for hepatic hydatid disease. Cystic echinococcosis CE is a complex, chronic and neglected disease with a worldwide distribution. In the definitive host the parasitic burden is determined by the number of protoscolices ingested. Research Grabulosus of This Article. Cystic echinococcal disease Echinococcus granulosus.

CE can be very difficult to treat and even more difficult to cure for a number of reasons.

Although the evidence base for clinical decision-making is still at the level of expert opinion, clinical management of hepatic CE patients is facilitated by the standardization of US classification, enabling clinicians to identify the most rational option on the basis of cyst stage[ 26]. A recent study highlighted the importance of at least 12 mo of follow-up, since it is difficult to predict cyst behavior after treatment[ 28 ].

Pulmonary involvement can produce chest pain, cough, and hemoptysis. Rupture of the cysts can produce fever, urticaria, eosinophilia, and anaphylactic shock, as well as cyst dissemination.

Metabolic viability assessment of cystic echknococcus using high-field 1H MRS of cyst contents. Tests for Arc 5 or IgE antibodies appear to reflect antibody decline during the first 24 months postsurgery, whereas the IHA and other tests remain positive for at least 4 years.

Some groups have evaluated these findings grranulosus attempted to categorize them relative to the type of surgical procedure performed[ 80 ]. Cyst growth and spontaneous cure in hydatid disease.

Echinococcus granulosus – Hydatid disease. The experience with catheterization techniques in CE2 and CE3b cysts is more recent and less extensive than that with PAIR, and results echinococcuw series with long-term follow-up are needed before their efficacy can be determined. Trial therapy of inoperable abdominal hydatid cysts by puncture.


The disease is complex and dynamic, with an evolving phase and quietly growing cysts, followed by an involution process during which the parasite is gradually dying, leaving behind a solidified, often calcified cyst granuloss a scar.

In the largest series published thus far, patients with cysts received mo continuous cycles of MBZ or ABZ treatment[ ]. Therefore, CE should always be included in the differential diagnosis of cystic lesions of the liver.

In light of these features, CE3b cysts should be considered as active, while CE3a are the transitional cysts sensu stricto. However, the clinician must have some knowledge of the characteristics of the available tests and the patient and parasite factors associated with false results.

The disease can be controlled successfully through health education and appropriate legislation only when people understand the life cycle of the parasite. Cyst diameter is a factor associated with a high risk of biliary-cyst communication in clinically asymptomatic patients.

As a rule, perioperative ABZ prophylaxis, from 1 wk prior to surgery until 4 wk postoperatively, is necessary to minimize the risk of secondary echinococcosis from seeding of protoscoleces in the abdominal cavity[ 59 ]. Notice a pair of refractile hooks yellow arrows.
