@susanf8 It is an alternative (not sufficiently considered) to ostomy/j-pouch for RECTAL surgery only, not for the resection of other parts of the colon, because, precisely, the rectum and the sygmoid are resected, a few centimeters of the colon are pulled through the anus, and a coloanal anastomosis is performed in a second surgery 5 to 7 days later. It constitutes a Low Anterior Resection (LAR) and leads to LARS (which varies in degree of severity depending on the individual). It is not an option for people having part of their ascendent, transversal or descendant colon resected.
