Purpose.To investigate the liver volume change and the potential of early evaluation by contrast-enhanced magnetic resonance imaging (MRI) using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) after portal vein embolization (PVE).Materials and Methods.Retrospective evaluations of computed tomography (CT) volumetry of total liver and nonembolized areas were performed before and 3 weeks after PVE in 37 cases. The percentage of future liver remnant (%FLR) and the change ratio of %FLR (%FLR ratio) were calculated. Prospective evaluation of signal intensities (SIs) was performed to estimate the role of Gd-EOB-DTPA-enhanced MRI as a predictor of hypertrophy in 16 cases. The SI contrast between embolized and nonembolized areas was calculated 1 week after PVE. The change in SI contrast before and after PVE (SI ratio) was also calculated in 11 cases.Results.%FLR ratio significantly increased, and SI ratio significantly decreased (bothP<0.01). There were significant negative correlations between %FLR and SI contrast and between %FLR and SI ratio (bothP<0.01).Conclusion.Hypertrophy in the nonembolized area after PVE was indicated by CT volumetry, and measurement of SI contrast and SI ratio in Gd-EOB-DTPA-enhanced MRI early after PVE may be useful to predict the potential for hepatic hypertrophy.

Objective: To assess the safety and efficacy of “polyhedral fenestration technique” (PFT), which we newly developed, in combined hepatectomy and cyst fenestration (CHCF) for symptomatic polycystic liver disease (PLD). Summary of background data: CHCF for PLD has been reportedly less efficacious for its invasiveness because 50% to 70% patients suffered recurrent symptoms after CHCF. Methods: Patient characteristics, intra- and early postoperative variables were compared between 5 PLD patients undergoing CHCF performed with PFT (PLD group) and 95 patients with diseases other than PLD receiving hepatectomy without biliary reconstruction during the same period (Control group) to assess safety of PFT. Chronological changes in total liver volume (TLV) measured by computed tomography (CT) volumetry as well as recurrent symptoms after CHCF were investigated to assess long-term outcomes. Results: Although ≧ Clavien-Dindo grade 2 complications were more common in the PLD group than in the Control group (PLD vs Control, 5/5[100%] vs 27/95[28%], p=0.004), patient characteristics, intra-, and early postoperative variables, including ≧ Clavien-Dindo grade 3 complications, were comparable among the 2 groups. Postoperative observational period of the 5 PLD patients ranged 30 to 88 months with a median of 63. CT volumetry revealed that TLV continued to reduce up to 1 year after surgery and thereafter retained less than 0.5 times of preoperative TLV in all patients. Recurrent liver enlargement or recurrent symptoms were not observed in any of the 5 PLD patients. Conclusions: Although our case series was very small, newly-developed PFT in CHCF for PLD yielded acceptable safety and excellent long-term outcomes.
