Ex-situ liver resection for complex Echinococcus multilocularis infection: a case report

Echinococcus multilocularis, the fox dwarf tapeworm, causes alveolar echinococcosis (AE), a critical and life-threatening condition. A radical surgical approach represents the only curative option. In this case study, we present a 37-year-old man diagnosed with extensive hepatic AE requiring ex-situ extended right-sided liver resection including the caudate lobe and retro-hepatic vena cava. The left liver segments were auto-transplanted with reconstruction of the left hepatic vein and an inferior vena cava graft. In the post-operative course, the patient developed a bile leak, which was successfully managed with endoscopic stent intervention. He was discharged after a three-week hospitalization. Medical treatment with albendazole was initiated preoperatively and continued postoperatively.
