Experiments in the development of a continent ileostomy: a simplified technique without a reservoir in dogs

A continent ileostomy without a reservoir was constructed in five dogs with minimal morbidity and mortality rates. The technique involved constructing a continent valve by retrograde intussusception of 8 cm of the terminal ileum, which was then exteriorized as an end ileostomy. The terminal ileum was emptied every 2 hours in the first week, 4 hours in the second week, 6 hours in the third week, and every 8 hours thereafter. This allowed it to gradually dilate and form its own natural reservoir. The follow-up period was 3 to 7 months. The animals remained fully continent to gas and feces. The reservoir capacity after 2 months was 600 cc. No pressure changes within the reservoir were observed with continuous infusion of saline solution.
