So sorry for the pain and problems, especially this soon after the surgery. Since my k pouch surgery I've never had bowel obstruction, although prior to the surgery I would get them on a weekly basis. The difference for me was because they removed extensive amount of adhesions on my intestine during the surgery. Also I previously had SIBO, which has miraculously disappeared since the surgery of close to two years ago.
Thus, I am sending sympathy but have no advice. Sorry. Keep us posted on specific diagnosis and treatment . Janet
