PERI-CYSTECTOMY VERSUS- CYSTOTOMY AND ENUCLEATION OF GERMINAL LAYER BY TISSUE SPEARING TECHNIQUE FOR LUNG HYDATID IN EGYPT

Echinococcal disease is caused by infection with the metacestode stage of the tapeworm Echinococcus,which belongs to the family Taeniidae. Four species of Echinococcus produce infection in humans; E.granulosus and E. multilocularis are the commonest, causing cystic echinococcosis (CE) and alveolarechinococcosis (AE), respectively. The clinical features of infection due to E. granulosus and E. multilocularisdiffered from each other. The two other species, E. vogeli and E. oligarthrus, cause polycysticechinococcosis but have only rarely had been ass-ociated with man. Surgery is still the gold standardtreatment, chemotherapy is retracted to some patient, because yields inconsistent result. The study was carriedout up on 16 male patients with single giant uncomplicated lung hydatid admitted to Kobry El Kobba MilitaryCampus. The patients was randomly divided into two groups, GI included 8 patients, of whom 6 patients withright lung lesion and 2 with left lung lesion. One of the 6 patients with right side liver lesion was treated bycystotomy, after aspiration of cyst fluid and enucleation of germinal layer and de-roofing the cyst. G II included8 patients, 4 patients with left side lesion and 4 with right side lesion and 2 patients had both lung andThe most diagnostic tool was chest radiography and CT. Treatment included medical and surgical treatmentwas divided into conservative surgery and radical surgery. Both groups were treated by conservativesurgical method but the outcome in GI was better than in GII.
