The purpose of this study was to assess the usefulness of a cauterizing laparoscopic linear stapler for intestinal anastomosis. In a porcine model, intestinal anastomoses performed with a standard laparoscopic linear stapler, a cauterizing laparoscopic linear stapler (RF stapler), and a two-layer, hand-sewn technique were compared by measuring bursting pressures at 4 and 7 days after surgery. During surgery, the RF stapler provided better hemostasis than the regular stapler for mesenteric transection. At 4 days, one leak occurred in the RF stapler group, and the bursting pressure in the RF stapler group was significantly lower than the bursting pressures in the regular stapler group and the hand-sewn group. In addition, the bursting pressure was significantly greater in the hand-sewn group than in the regular stapler group at 4 days. By 7 days, there were no differences in bursting pressure among the groups. We recommend that the RF stapler not be used for intestinal anastomosis. However, the device may be beneficial for controlling vasculature.
本研究的目的是评估一种用于肠道吻合术的烧灼式腹腔镜线性缝合器的效用。在猪模型中，通过测量术后4天和7天的破裂压力，比较了使用标准腹腔镜线性缝合器、烧灼式腹腔镜线性缝合器（射频缝合器）和两层手工缝合技术进行的肠道吻合术。手术过程中，射频缝合器在肠系膜横断时比普通缝合器提供了更好的止血效果。在术后4天，射频缝合器组出现1例渗漏，且该组的破裂压力显著低于普通缝合器组和手工缝合组。此外，术后4天时，手工缝合组的破裂压力显著高于普通缝合器组。到术后7天，各组之间的破裂压力没有差异。我们建议不要将射频缝合器用于肠道吻合术。然而，该器械可能有助于控制脉管系统。
