In a recent paper, Rivas (1926) has reported the results of duodenal and colonic lavage for the treatment of gastro-intestinal parasitism, poisoning and other conditions in man and dogs. On the basis of tests he concludes that protozoan and metazoan parasites are killed in about ten minutes at 45°C. and in a few minutes at 47°C. and believes that the passage of worms during febrile conditions, a thing quite generally thought to be of common occurrence, is due to the increase in temperature.

His experiments on dogs were as follows: One dog was treated, following a preliminary laparotomy, by inserting a trocar in the duodenum and flushing the intestines with 900 cc. of water at 52° to 55°C.; this removed 7 tapeworms, 19 ascarids, and 11 hookworms; dog died four days later; postmortem, no parasites, but a hemorrhagic enteritis present.
