The passage discusses the use of X-irradiation for treating benign ulcer disease in dogs, highlighting the challenges and clinical outcomes. The treatment, which involves eight treatments of 1600 rads, can last up to 40 days. The techniques used at the University of Chicago are detailed, and the results show a significant reduction in ulcer recurrence compared to the control group. However, the treatment is controversial and not widely accepted. The book also addresses concerns about radiation-induced neoplasia, which, according to careful follow-up, does not appear to be a significant complication. Despite criticisms of the book's organization and the lack of a gastroenterologist's perspective, the treatment remains relevant for certain patients with severe recurrent disease.The passage discusses the use of X-irradiation for treating benign ulcer disease in dogs, highlighting the challenges and clinical outcomes.
