Alveococcosis of the liver - strategy of surgical treatment with special focus on liver transplantation.

BACKGROUND

Echinococcosis is a zoonosis caused by infestation with any of 4 (of the 16) members of the Echinococcus genus, namely Echinococcus granulosus, Echinococcus multilocularis, Echinococcus oligarthus, and Echinococcus vogelii. The aim of this retrospective analysis was to present the outcomes of patients undergoing liver resection and liver transplantation (LT) for E. multilocularis infection.

METHODS

A total of 44 patients who underwent surgical treatment of E. multilocularis infection in the period between 1989 and 2014 were included in the study cohort and retrospectively analyzed.

RESULTS

LT was performed in 22 patients (50.0%), including 4 of 26 patients undergoing initial non-transplant management. Non-transplant procedures comprised liver resection in 23 patients (88.5%), diagnostic laparoscopy in 2 (7.7%), and left adrenalectomy in 1 patient (3.8%). Post-transplantation survival rates were 90%, 85%, and 75% at 1, 5, and 10 years, respectively.

CONCLUSION

In conclusion, LT for E. multilocularis infection is a safe and effective treatment method.
