The recently reported vagal nerve stain leucomethylene blue was assessed in 20 patients as an intraoperative aid to attaining complete vagotomy. Of 101 stained specimens removed at surgery, only 30 (30%) contained nerve tissue. Four of 17 postoperative insulin tests were positive by Hollander's criteria. The dye technique was found to be an unreliable method of ensuring complete vagotomy at the time of surgery.
最近报道的迷走神经染色剂亮亚甲蓝在20例患者中作为术中辅助手段以实现完全迷走神经切断术进行了评估。在手术中切除的101个染色标本中，只有30个（30%）含有神经组织。按照霍兰德标准，17例术后胰岛素试验中有4例呈阳性。发现该染色技术在手术时确保完全迷走神经切断术是一种不可靠的方法。
