Hi I had my jpouch surgery 1yr. agoand still experience leakage mostly at night. I am currently seaking physical therapy for this matter. What she recommends doing is sticking your index finger,candle stick,or a pencil these hings must be covered with some kind of barrier like a condom. I have only been brave enough to use my finger ( ya, I know gross!) and sqeeze as many times as possible. And last your kagels are very important. If this is not done our muscle gets weak and no longer works! Well i hope thia is some help o some one out there!!
