为了阐明肝脏恶性肿瘤行肝切除术后膈下感染发生的高危因素，我们对１１０例肝脏恶性肿瘤施行的肝切除术进行回顾性分析，其中９例发生膈下感染，发生率８．１８％。结果表明，膈下感染的发生与肝切除范围，是否伴肝硬化背景和术中出血量有关；与原发性肝癌的病程或分期无关；术后膈下与残肝面的通畅引流是防止肝切除术后膈下感染发生的关键因素。
In order to elucidate the risk factors for subgingival infection after hepatectomy for hepatic malignancies, we conducted a retrospective analysis of 110 cases of hepatectomy for liver malignancies. Among them, 9 cases had subgingival infections, and the incidence was 8.18%. The results showed that the occurrence of subphrenic infection was related to the extent of liver resection, whether it was associated with cirrhosis background and intraoperative blood loss; it was not related to the course or stage of primary liver cancer; the smooth drainage of postoperative axilla and residual liver surface was to prevent liver damage. The key factors for the occurrence of subphrenic infection after resection.
