Kock ileostomy A surgical method presented by Dr. Nils Koch in Gothenburg, Sweden in the late 1960´s. Kock ileostomy (also called Kock pouch, continent ileostomy) consists of an internal reservoir and a valve, both constructed from the distal part of the small bowel. The opening with the valve was then insterted through the bowel wall and the patient could empty the reservoar when needed (abotu four times aday) with a small tube.Kock ileostomy is nowadays rarely done as J-pouch has become the operation of choice when patients need a colectomy because of ulcerative colitis.
