为了探讨微波刀行肝段切除之可行性，经过19例临床实践与9例同期未使用微波刀行肝段切除相比较得出：19例微波刀行肝段切除术其平均每例出血量和输血量为361ml和421ml；其并发症为2例。9例未使用微波刀行肝段切除术其平均出血量和输血量为581ml和722ml；其并发症为4例。两组相比其出血量、输血量及并发症均有明显差异性（均P＜0．05）。本组患者无手术及住院死亡。进而说明微波刀行肝段切除术出血量小、并发症少和死亡率低，是一种安全、有效和符合肝脏解剖特点的手术，值得推广应用。
In order to investigate the feasibility of microwave resection for liver segment resection, 19 cases of clinical practice were compared with 9 cases of unresected microwave resection. The blood transfusion volume was 361 ml and 421 ml; its complications were 2 cases. The average blood loss and blood transfusion volume of nine patients who did not use microwave knife resection was 581ml and 722ml; the complications were 4 cases. The bleeding volume, blood transfusion volume, and complications were significantly different between the two groups (all P<0.05). This group of patients died without surgery and hospitalization. Furthermore, it was demonstrated that the microwave knife-lined hepatectomy had less bleeding, fewer complications, and lower mortality. It was a safe, effective, and hepatic anatomical feature. It is worthy of popularization and application.
