The LigaSure system (Valleylab, Boulder, CO) seals vessels by reforming collagen and elastin in vessel walls. We studied the feasibility and effectiveness of LigaSure in dividing porcine small bowel.
Twelve porcine small bowel portions were randomized to division with either endoscopic linear stapler or LigaSure system and the burst pressure of the sealed ends were measured.
Segments sealed with staples (6), LigaSure Atlas (Valleylab) (7), LigaSure Xtd (Valleylab) (4), and double-sealed with LigaSure Atlas (Valleylab) (4) were compared. Burst pressure for stapled segments was 131 (standard deviation [SD] 19) mm Hg; failure occurred in the bowel wall. Burst pressures for the 3 groups of Ligasure segments were 27 (SD 5), 20 (SD 6), and 11 (SD 13) mm Hg, respectively, with no statistically significant difference among them; failure occurred at the sealed end. Burst pressure for stapled segments was significantly higher than that of Ligasure segments (P < .001).
LigaSure does not safely seal small bowel.
LigaSure系统(美国科罗拉多州博尔德市柯惠医疗公司)通过重塑血管壁中的胶原蛋白和弹性蛋白来封闭血管。我们研究了LigaSure用于分割猪小肠的可行性和有效性。
将12个猪小肠段随机分为两组,分别使用内镜直线切割吻合器或LigaSure系统进行分割,并测量封闭端的爆破压力。
比较了用吻合器封闭的节段(6个)、用LigaSure Atlas(柯惠医疗公司)封闭的节段(7个)、用LigaSure Xtd(柯惠医疗公司)封闭的节段(4个)以及用LigaSure Atlas(柯惠医疗公司)双重封闭的节段(4个)。用吻合器封闭的节段的爆破压力为131(标准差[SD]19)毫米汞柱;肠壁出现破裂。三组Ligasure节段的爆破压力分别为27(SD 5)、20(SD 6)和11(SD 13)毫米汞柱,它们之间无统计学显著差异;破裂发生在封闭端。用吻合器封闭的节段的爆破压力显著高于Ligasure节段(P <.001)。
LigaSure不能安全地封闭小肠。
