J-pouch coloanal anastomosis
Encyclopedia
J-pouch coloanal anastomosis is a surgical procedure in which the colon
is attached to the anus
after the rectum
has been removed. A 2-4 inch section of the colon is formed into a J-shaped pouch
in order to replace the function of the rectum and store stool
until it can be eliminated. This procedure is similar to the side-to-end coloanal anastomosis
but a larger pouch is formed.
