比较Ligasure^TM血管闭合系统和传统结扎方法在开放式胃癌D₂根治术中应用的安全性和疗效。

2006年6月至2008年12月间行胃癌D₂根治术86例患者，随机分为Ligasure^TM组（45例）和传统手术组（41例），比较两组患者的手术时间、术中出血量、术后疗效及并发症等临床资料。

两组均无手术死亡，Ligasure^TM组手术时间、术中出血量显著低于常规手术组（P<0.05），术后平均淋巴结检出数、并发症发生率、肛门排气时间、术后住院日无统计学差异。Ligasure^TM组术后第1天腹腔引流液少于常规手术组（P<0.05），第2~5天及术后总量两组无统计学差异。

Ligasure^TM血管闭合系统在胃癌D2根治术中安全可靠，与传统结扎手术相比术中出血减少，手术时间缩短，具良好的临床应用价值。

To evaluate the the efficacy and safety of Ligasure^TM Vessel Sealing System and conventional clamping method in gastric D₂ lymphadenectomy.

Patients undergoing gastric D2 lymphadenectomy were randomly divided into two groups treated with Ligasure^TM(n=45) and conventional method (n=41), Operation time, intraoperative blood loss, postoperative courses and complications were analyzed prospectively.

There were no hospital deaths. The operation time, intraoperative blood loss in Ligasure^TM group were significantly less than that in conventional operation (P<0.05). No significant differences were found between the two groups in number of lymph node removed, postoperative complications, time to pass flatus and hospital stay. The volume of intraperitoneal drainage in Ligasure^TM group were less than those in conventional group at the first day (P<0.05), but there was no significant difference from the 2nd to the 5th day after operation.

The Ligasure^TM Vessel Sealing System is safe and effective for use in gastric D2 lymphadenectomy, and is associated with a shorter operation time and decreased blood loss compared with conventional surgery.
