我们应用逐步回归分析法对我院经手术及病理确诊的８４例原发性肝癌进行了统计分析。结果表明在调查的１３个因素中（包括肿瘤位置、直径、有无肝硬变、肿瘤与周围器官有无粘连、麻醉方法、手术切口类型、肝切除量、切线距瘤体距离、肝血流阻断方式、出血量、补血量、手术时间及术中低血压时间），术中出血量及手术时间与术后恢复的关系最大。如出血量＞１５００ｍｌ，手术时间＞２４０ｍｉｎ则术后并发证明显增加。其它因素则多数与这两项因素存在不同程度的相关关系。术中注意控制这些因素有助于缩小术后风险。
We applied stepwise regression analysis to statistical analysis of 84 cases of primary liver cancer diagnosed by surgery and pathology in our hospital. The results showed that among the 13 factors investigated (including tumor location, diameter, presence or absence of cirrhosis, adhesion of tumors to surrounding organs, anesthesia method, surgical incision type, hepatectomy, tangential distance from the tumor, liver blood flow Blockage, blood loss, blood volume, operation time, and intraoperative hypotension time. The relationship between intraoperative blood loss and operation time and postoperative recovery was greatest. If the amount of bleeding> 1500ml, surgery time> 240min then the postoperative complications showed significant increase. The other factors are mostly related to the two factors in different degrees. Intraoperative attention to control these factors helps reduce postoperative risk.
