Viosterol (Irradiated Ergosterol)

Abstract

bleeding and eroding posterior wall duodenal ulcers ; the end-results as related to cures are probably higher than after gastro-enterostomy. It also removes the lesion together with the possibility of malignant degen¬ eration in the intractable gastric ulcer which has failed to heal completely under medical management. It is not an operation to· be condemned in bleeding duodenal and in intractable gastric ulcers. In properly selected risks, such as nonobese persons in good condition, in properly selected lesions, particularly those which are movable and those which permit good closure of the duodenal stump, the operation has in our hands been valuable and will, I believe, come to occupy in the future, when prejudice for it and against it has been overcome, a definite but not universal position in the treatment of intractable gastric and duodenal ulcer. The mortality of partial gastrectomy, even if as low as 6 or 7 per cent, is too high, I believe, to permit its uni¬ versal application to all duodenal ulcers.The operation today, as yet unproved by time and by application in the hands of a variety of surgeons, but which to my mind offers most logical hope for the future in the surgery of duodenal ulcer, is the pyloroplasty with large partial excision of the pyloric
