| Abstract | ||||
| Echinococcosis (known as hydatid disease or hydatidosis) is a serious, sometimes fatal, zoonotic disease caused by Echinococcus two species. E. granulosus, causes worldwide cystic echinococcosis (hydatidosis) maintained in domestic transmission cycle involving dogs and livestock mainly sheep, and E. multilocularis, causes alveolar echinoccososis endemic in the northern hemisphere in wild transmission cycle involving dogs and wild carnivores and rodents. Intermediate hosts including man are infected by ingestion of eggs dropped from dog with food, fluid or fingers, or by crawling insects from site of fecal deposition. Eggs hatch in gut into invasive oncospheres, which penetrate intestinal mucosa, enter venous and lymphatic pathways. These oncospheres according to species developed into unilocular or classical hydatid disease or cystic echinococcosis, with few years’ incubation period or infiltration into alveolar or multilocular echinoccososis with 10-30 years incubation period. The clinical pictures of E. granulosus were usually from asymptomatic to fatal. But, alveolar echinoccososis particularly in the liver becomes metastatic and is frequently fatal. Chemotherapies (albendazole, mebendazole or praziquantil) may be of value prior to surgery or in inoperable cases, but alveolar cysts may require both surgery and prolonged chemotherapeutic treatment. Liver surgery has gone through the phases of wedge liver resection, regular resection of heaptic lobes, irregular and local resection, extracorporeal hepatectomy, hemi-extracorporeal hepatectomy and others. Taking the modern technologies advantage, the liver surgery is stepping into an age of precise liver resection. | ||||
