RT Journal Article SR Electronic T1 The selective nerve stain leucomethylene blue as an intraoperative aid to achieving complete vagotomy JF Gut JO Gut FD BMJ Publishing Group Ltd and British Society of Gastroenterology SP 881 OP 882 DO 10.1136/gut.11.10.881 VO 11 IS 10 A1 Frimer, M. L. A1 Cohen, M. M. A1 Harrison, R. C. A1 Holubitsky, I. B. YR 1970 UL http://gut.bmj.com/content/11/10/881.abstract AB 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.
