Background: Patients with hepatocellular carcinoma (HCC) and portal vein hypertension assessed with platelet count (PVH-PLT; platelet count < 100,000/mL) are often denied surgery even when the disease is technically resectable. Short- and long-term outcomes of patients undergoing minimally invasive surgery (MIS) versus open resection for HCC and PVH-PLT were compared. Methods: Propensity score matching (PSM) was used to balance the clinicopathological differences between MIS and non-MIS patents. Univariate comparison and standard survival analyses were utilized. Results: Among 1974 patients who underwent surgery for HCC, 13% had a PVH-PLT and 33% underwent MIS. After 1:1 PSM, 407 MIS and 407 non-MIS patients were analyzed. Incidence of complications and length-of-stay (LoS) were higher among non-MIS versus MIS patients (both p ≤ 0.002). After PSM, among 178 PVH-PLT patients (89 MIS and 89 non-MIS), patients who underwent a non-MIS approach had longer LoS (> 7 days; non-MIS: 55% vs. MIS: 29%), as well as higher morbidity (non-MIS: 42% vs. MIS: 29%) [p <0.001]. In contrast, long-term oncological outcomes were comparable, including 3-year overall survival (non-MIS: 66.2% vs. MIS: 72.9%) and disease-free survival (non-MIS: 47.3% vs. MIS: 50.2%) [both p ≥ 0.08]. Conclusion: An MIS approach was associated with improved short-term outcomes, but similar long-term outcomes, compared with open liver resection for patients with HCC and PVH-PLT. An MIS approach for liver resection should be considered for patients with HCC, even those individuals with PVH-PLT.

Abstract
Background: Patients with hepatocellular carcinoma (HCC) and portal vein hypertension assessed with platelet count (PVH-PLT; platelet count < 100,000/mL) are often denied surgery even when the disease is technically resectable. Short- and long-term outcomes of patients undergoing minimally invasive surgery (MIS) versus open resection for HCC and PVH-PLT were compared. Methods: Propensity score matching (PSM) was used to balance the clinicopathological differences between MIS and non-MIS patents. Univariate comparison and standard survival analyses were utilized. Results: Among 1974 patients who underwent surgery for HCC, 13% had a PVH-PLT and 33% underwent MIS. After 1:1 PSM, 407 MIS and 407 non-MIS patients were analyzed. Incidence of complications and length-of-stay (LoS) were higher among non-MIS versus MIS patients (both p ≤ 0.002). After PSM, among 178 PVH-PLT patients (89 MIS and 89 non-MIS), patients who underwent a non-MIS approach had longer LoS (> 7 days; non-MIS: 55% vs. MIS: 29%), as well as higher morbidity (non-MIS: 42% vs. MIS: 29%) [p <0.001]. In contrast, long-term oncological outcomes were comparable, including 3-year overall survival (non-MIS: 66.2% vs. MIS: 72.9%) and disease-free survival (non-MIS: 47.3% vs. MIS: 50.2%) [both p ≥ 0.08]. Conclusion: An MIS approach was associated with improved short-term outcomes, but similar long-term outcomes, compared with open liver resection for patients with HCC and PVH-PLT. An MIS approach for liver resection should be considered for patients with HCC, even those individuals with PVH-PLT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
