Presacral venous haemorrhage during rectal movement is low, but is often massive, and even fatal. Our objective is the "in vitro" determination of the results of electrocoagulation applied to a fragment of muscle on the sacral bone surface during rectal resection due to a malignant neoplasm of the rectum.
Single-pole coagulation was applied "in vitro" with the selector at maximum power on a 2×2 cms muscle fragment, applied to the anterior side of the IV sacral vertebra until reaching boiling point. The method was used on 6 patients with bleeding of the presacral venous plexus.
In the "in vitro" study, boiling point was reached in 90 seconds from applying the single-pole current on the muscle fragment. Electrocoagulation was applied to a 2×2 cm rectal muscle fragment in 6 patients with presacral venous haemorrhage, using pressure on the surface of the presacral bone, with the stopping of the bleeding being achieved in all cases.
The use of indirect electrocoagulation on a fragment of the rectus abdominis muscle is a straightforward and highly effective technique for controlling presacral venous haemorrhage.
直肠手术中骶前静脉出血发生率较低，但常出血量大，甚至致命。我们的目的是“体外”测定在因直肠恶性肿瘤行直肠切除术中，对骶骨表面肌肉碎片进行电凝的效果。
在体外，将选择器调至最大功率，对一块2×2平方厘米的肌肉碎片进行单极电凝，该碎片置于骶骨椎体IV的前侧，直至达到沸点。该方法应用于6例骶前静脉丛出血患者。
在“体外”研究中，对肌肉碎片施加单极电流后90秒达到沸点。对6例骶前静脉出血患者的2×2厘米直肠肌肉碎片进行电凝，通过对骶骨表面施压，所有病例均实现了止血。
对腹直肌碎片使用间接电凝是控制骶前静脉出血的一种直接且高效的技术。
