BACKGROUND
Two sizes of endoscopic gastrointestinal anastomosis (Endo-GIA) staples are currently available for vascular control. The purpose of this study was to compare the Endo-GIA 30-2.0 mm with the Endo-GIA 30-2.5 mm vascular staple.
METHODS
The renal blood vessels, aorta, and vena cava were divided laparoscopically using the Endo-GIA 30-2.0 and 30-2.5 mm in four pigs, respectively. The arterial and venous segments were harvested en bloc for ex vivo burst pressure studies.
RESULTS
Both 2.0-mm and 2.5-mm staples achieved vessel sealing at supraphysiologic mean burst pressures (> or =310 mmHg). There were no statistical differences between mean burst pressures of vessels stapled by 2.0-mm compared to 2.5-mm staples. Both staples sealed arteries up to 17 mm and veins up to 22 mm in diameter.
CONCLUSION
Endo-GIA 30-2.0 mm and 30-2.5 mm vascular staples are equivalent in sealing vessels at supraphysiologic mean burst pressures.
背景
目前有两种尺寸的内镜下胃肠吻合器（Endo - GIA）钉仓可用于血管控制。本研究的目的是比较Endo - GIA 30 - 2.0毫米与Endo - GIA 30 - 2.5毫米血管吻合钉仓。
方法
分别使用Endo - GIA 30 - 2.0毫米和30 - 2.5毫米吻合钉仓在四只猪身上腹腔镜下分割肾血管、主动脉和腔静脉。将动脉和静脉段整块切除用于体外破裂压力研究。
结果
2.0毫米和2.5毫米的吻合钉仓均在超生理平均破裂压力（≥310毫米汞柱）下实现血管封闭。2.0毫米吻合钉仓与2.5毫米吻合钉仓吻合血管的平均破裂压力之间无统计学差异。两种吻合钉仓均可封闭直径达17毫米的动脉和直径达22毫米的静脉。
结论
Endo - GIA 30 - 2.0毫米和30 - 2.5毫米血管吻合钉仓在超生理平均破裂压力下封闭血管的效果相当。
