The data of 60 consecutive patients who underwent LR for HCA were analyzed. Twenty-one patients (35.0%) underwent LR plus PVR and 39 (65.0%) LR only. Clinicopathologic data were evaluated by the use of uni- and multivariate analyses.
The majority of resections was performed for Bismuth–Corlette type III/IV tumors (97.3%). Hepatectomy involved trisectionectomies in 41 patients (68.3%). R1 resection margin status was identified as adverse prognosis factor for survival (hazard ratio 3.61; P = .003). PVR increased the perioperative morbidity (P = .04). The 90-day mortality rate was comparable between both groups (P = .70). Negative resection margin status was similar between groups (P = .70). The lymph node clearance was equal (P = .86). PVR was not associated with a beneficial long-term outcome, the 5-year and disease-free survival were comparable (LR only 17.8% vs LR plus PVR 20.0% [P = .89] and LR only 10.6% vs LR plus PVR 21.4% [P = .63]). PVR was no prognostic factor for tumor-dependent or disease-free survival (hazard ratio 0.64; P = .26 and hazard ratio 0.76; P = .47).
The presented data indicate that simultaneous PVR has no beneficial impact on oncologic long-term outcome in patients undergoing LR for HCA. Because it increases the perioperative morbidity, a recommendation for routine application cannot be given.
