Enucleation of centrally located giant hepatic hemangioma: report of two cases.

Two centrally located giant hepatic hemangiomas were referred with severe pain, one of which had a protruding abdominal mass was listed for transplantation at another center. Tumors were 35 and 30 cm at their longest diameter. One was centrally located involving the hilum and segments VI/VII and II/III were partially spared. Volumetric analysis and imaging suggested enucleation is feasible if the left lateral segment and the right posterior sector are left intact. Operation was straightforward except few breaks in enucleation technique in an effort to secure the venous drainage of the remnant liver. She had an uneventful recovery except a biliary fistula through the operatively severed left hepatic duct, which was repaired over a stent. This was managed by lateral segmentectomy and resection of the fistula after the enlargement of the right posterior sector was confirmed volumetrically. The other tumor-involved segments II, III, IV, V, and VIII and the hilum were totally hemangiomatic. Enucleation and postoperative recovery was uneventful. The era of liver transplantation enhanced our knowledge about complex liver surgery and these cases are good examples about the feasibility of enucleation even in extremely complicated liver hemangiomas saving both the patients and a donor liver.
