Postoperative recurrence of cystic hydatidosis. In seronegative patients with hepatic image findings compatible with echinococcosis, ultrasound guided fine needle biopsy may be useful for confirmation of diagnosis; during such procedures precautions must be taken to control allergic reactions or prevent secondary recurrence in the event of leakage of hydatid fluid or protoscolices.

The experience with catheterization techniques in CE2 and CE3b cysts is more recent and less extensive than that with PAIR, and results from series with long-term follow-up are needed before their efficacy can be determined. Serologic testing for CE is hampered by many problems[ 41 – echinococvus45 ]. Postoperative recurrence in hepatic hydatid disease. Currently, lipoprotein antigen B AgB and Ag5, the major components of cystic fluid, have received the most attention with regard to diagnosis, but purified cyst hydatid fluid is still the most widely used in current assays for immunodiagnosis of CE, which are not geanulosus 4142 ].
