Following a bowel movement sometime later usually during my walk, I have feces leak from rectum. Not watery but solid. My doctor thinks there may be a pocket in colon that holds a small amount and it leaks out. Colonoscopy showed nothing. I cannot feel it when it happens. It will occur after every bowel movement. My primary doctor suggest a saline enima following the b m. That seems to help control it. But there has to be a reason for this. I have heard the term overflow but don t know what it means. Thank you
