目的:
LT の経験が局所進行肝胆道悪性腫瘍に対する CLR の転帰に与える影響を研究する。過去数十年の間にLTの知識と手術手技が進化したにもかかわらず、CLRの実施におけるLT経験の重要性を評価するデータはまだない。
OBJECTIVE: To study the impact of LT experience on the outcome of CLR for locally advanced hepatobiliary malignancy SUMMARY OF BACKGROUND DATA:: Despite evolution in LT knowledge and surgical techniques in the past decades, there is yet data to evaluate the significance of LT experience in performing CLR.
方法:
1995年から2019年までのCLR後の術後転帰をレビューし、LTとCLRの両方のサービスを提供している単一施設でのLT経験と相関関係を検討した。CLRは、血管再建を伴う肝切除術、または多嚢胞切除術、中央二等分切除術(S4/5/8)、または段階的肝切除術のための肝分割と門脈結紮を伴う肝切除術と定義した。CLR関連の転帰とLT経験との関連を定義するために、スピアマン順位相関とレシーバー操作特性分析が用いられた。
METHODS: Postoperative outcome after CLR between 1995 and 2019 were reviewed and correlated with LT experience in a single center with both LT and CLR service. CLR was defined as hepatectomy with vasculobiliary reconstruction, or multivisceral resection, central bisectionectomy (S4/5/8), or associating liver partition and portal vein ligation for staged hepatectomy. Spearman rank correlation and receiver operating characteristic analysis were used to define the association between CLR-related outcomes and LT experience.
結果:
単施設での累積経験は1452例で、CLRは222例[胆道再建を伴う肝切除術(27.0%)、血管再建を伴う肝切除術(21.2%)、多臓器切除を伴う肝切除術(9.9%)、肝分割と門脈結紮を伴う段階的肝切除術(18.5%)]であり、主に肝細胞癌(53.2%)、肝門部胆管癌(14%)を対象としている。腫瘍サイズの中央値は7.0"Zs_200A"cmであった。その他の特徴は、大血管浸潤(23.4%)、副腎浸潤(14%)などであった。主な術後合併症率は25.2%、死亡率は6.3%であった。CLRの合併症率はLT経験と逆相関していた(R = -0.88, P < 0.005)。多変量解析では、輸血、手術時間の延長、LT経験 </=95 が主要な術後合併症と関連していることが示された。
RESULTS: With cumulative single-center experience of 1452 LT, 222 CLR were performed during the study period [hepatectomy with biliary (27.0%), or vascular (21.2%) reconstruction, with multivisceral resections (9.9%), with associating liver partition and portal vein ligation for staged hepatectomy (18.5%)] mainly for hepatocellular carcinoma (53.2%), and hilar cholangiocarcinoma (14%). Median tumor size was 7.0 cm. Other features include macrovascular invasion (23.4%), and juxta-visceral invasion (14%). Major postoperative complication rate was 25.2% and mortality rate was 6.3%. CLR-complication rate was inversely associated with LT experience (R = -0.88, P < 0.005). Receiver operator characteristic analysis revealed the cutoff for LT experience to have the greatest influence on CLR was 95 with a sensitivity of 100% and Youden index of 1. Multivariable analysis showed that blood transfusion, prolonged operating time, LT experience </=95 were associated with major postoperative complications.
結論:
局所進行性肝胆道悪性腫瘍に対しては、LT経験はCLRを補完するものであり、術後の転帰は改善された。
CONCLUSION: LT experience was complimentary to CLR for locally advanced hepatobiliary malignancy with improved postoperative outcome.
