Laparotomy closure relies on the incisional edges as anchor for the suture material. The results of these techniques are not satisfying, with failure rates of up to 20%. To investigate the effect of different conventional closure techniques and a novel "bridging technique" on abdominal wall perfusion an animal study was performed in rabbits. Abdominal wall perfusion was measured using the method of dynamic laser-fluorescence videography in the first 72 h of incisional wound healing in 25 animals. Suture tension was controlled with a water-filled polyurethane balloon connected to a pressure detector. The effect of laparotomy closure on abdominal wall tissue perfusion depends significantly on the applied technique and suture tension. Avoiding direct sutures in the incisional edges during laparotomy closure leads to a better tissue perfusion of the incisional region than conventional suture techniques. Suture tension can be controlled and adjusted using a water-filled polyurethane balloon as a pressure sensor.
剖腹手术切口的闭合依赖于切口边缘作为缝合材料的锚定部位。这些技术的效果并不令人满意，失败率高达20%。为了研究不同传统闭合技术和一种新型“桥接技术”对腹壁灌注的影响，在兔子身上进行了一项动物研究。在25只动物切口愈合的前72小时内，采用动态激光荧光摄像法测量腹壁灌注。通过连接压力探测器的充水聚氨酯球囊控制缝合张力。剖腹手术切口闭合对腹壁组织灌注的影响显著取决于所应用的技术和缝合张力。与传统缝合技术相比，在剖腹手术切口闭合过程中避免在切口边缘直接缝合可使切口区域获得更好的组织灌注。可使用充水聚氨酯球囊作为压力传感器来控制和调节缝合张力。
