目的评估PK刀在腹腔镜阑尾切除（LA）中的应用价值。方法回顾性分析广西桂东人民医院2009年6月至2010年6月期间68例行LA患者的临床资料，其中PK刀组34例，高频电凝钩组34例，比较2组患者的手术时间、术中出血量、术后肠道功能恢复时间及住院时间。结果所有手术均获成功，无中转开腹及术后大出血等并发症发生，PK刀组较高频电凝钩组的手术时间明显缩短(Plt;0.05)、术中出血量明显减少(Plt;0.05)及术后肠道功能恢复时间更快(Plt;0.05)； 住院时间2组间差异无统计学意义(Pgt;0.05)。结论PK刀具有凝固均匀、完全、热损伤少、止血效果好、操作简单等优点，可选择性地应用于LA。
Objective To explore the curative effect of surgical treatment for primary liver cancer with portal vein tumor thrombus（PVTT）. Methods The clinical data of 227 patients who were performed surgical treatment because of primary liver cancer with PVTT were analyzed retrospectively. Results Two hundreds and seventeen cases were performed surgical resection, 14 cases died from postoperative complications. The median survival time was 17.7 months, and the l-, 2-, 3-, and 5-year survival rates were 61.9%, 37.2%, 21.7%, and 4.0% respectively. There were 40 cases with PVTT ofⅠtype, the l-, 2-, 3-, and 5-year survival rates were 82.3% , 61.7%, 38.6%, and 6.6% respectively，which was obviously higher than those with PVTT of Ⅱ type （n=129, 61.1%, 34.3%, 20.8%, and 5.3%） and PVTT of Ⅲ type （n=48, 46.8%, 24.0%, 9.6%, and 0）, P＜0.05. There were 84 cases whose PVTT and tumor were resected together, the l-, 2-, 3-, and 5-year survival rates were 67.3%, 43.2%, 28.1%, and 7.9% respectively，which were obviously higher than those patients whose PVTT were removed from cross-section of liver （n= 85, 65.1%, 38.8%, 22.3%, and 3.4%） and patients whose PVTT were removed by cutting the portal vein （n=48, 46.8%, 24.0%, 9.6%, and 0）, P＜0.05. The l-, 2-, 3-, and 5-year survival rates of 76 cases who received postoperative therapy of TACE/TAI were 75.3%, 53.2%, 33.1%, and 5.7% respectively, which were obviously higher than those patients who were not received any postoperative therapy （n=141, 54.8%, 29.1%, 15.9%, and 3.2%）, P＜0.05. Conclusions Surgical treatment is an effective treatment for primary liver cancer with PVTT. Surgery should strive for resecting the tumor and PVTT together, and postoperative therapy of TACE/TAI may have a favorable effect on the long term survival rate.
