The aim of this work is to try to compare the results of different methods of circumferential small nerve suture according to the degree of magnification and type of microsurgical technique. Four techniques were studied in forty Wistar rats. 1. Microsurgical suture with the Set technique. Magnification 25, accurate suture. 2. Microsurgical suture with simple end to end approximation. Magnification 25, accurate suture. 3. Same technique, but delayed suture. 4. Suture with a simple end to end approximation. Magnification 4. Four stitches for reapproximation. After four months the sutured nerves have been studied both electrophysiologically and histologically. The results show clearly that the so-called set technique associated with an accurate circumferential suture with eight stitches under high magnification gives by far the best results, the regeneration rate of the nerve being higher than 80%. The results in groups 3 and 4 are definitely less good. The simple bringing together of both stumps under low magnification with only four stitches (group 4) gives the worst results with only 20% of regeneration.
这项工作的目的是根据放大程度和显微外科技术类型，尝试比较不同圆周小神经缝合方法的结果。在40只Wistar大鼠身上研究了四种技术。1. 使用Set技术进行显微缝合。放大倍数25，精确缝合。2. 简单端端对合的显微缝合。放大倍数25，精确缝合。3. 相同技术，但延迟缝合。4. 简单端端对合缝合。放大倍数4。四针进行重新对合。四个月后，对缝合后的神经进行了电生理和组织学研究。结果清楚地表明，在高倍放大下用八针进行精确圆周缝合的所谓Set技术，迄今为止效果最佳，神经再生率高于80%。第3组和第4组的结果肯定较差。在低倍放大下仅用四针将两个残端简单对合（第4组），效果最差，再生率仅为20%。
