title: [Use of a new selective stain for demonstrating the vagal fibers in gastric surgery. Experimental study].
abstract: Scalar concentrations (0.4%-0.2%-0.1%-0.05%) of methylene blue in a 7.02% ascorbic acid solution have been used in animals and humans for visualizing vagal branches at gastric level. These solutions constitute a simplified variation of Lee's test and the most effective for determining vagal fibres proved to be the 0.1% concentration.
