[Replacement of Bauhin's valve with an end-to-end telescope anastomosis between the ileum and transverse colon. Experimental study in dogs].

A method of a telescope anastomosis for prevention of reflux was developed experimentally in dogs. After the resection of 40 cm of ileum and colon ascendens the ileal part was intussuscepted into the colon and fixed by seromuscular stiches. The vessels were left untouched. The intussuscepted part measured 3-4 cm. No ileus was observed in the 24 weeks. Glass balls of 1.2 cm diameter could pass through. Barium enema as well as air insufflation of different pressures showed no reflux. The serosa was covered pretty soon by a granular tissue and later on by normal mucosa.
