Hi Alex, My first pouch failed because of a separation on the staple line. I was hopeful that it could be repaired but no joy and I elected to have a pouch advancement. A diversionary ileostomy was created during the first surgery. Three months later, the cuff (the bit of colon that remains in a typical j-pouch surgery) was removed, the pouch was reshaped and brought-down and the new connection was hand sewn. After I healed, I was reconnected. Early j-pouch surgeries all used a hand-sewn connection. Surgeons moved to a cuff with a stapled connection becasue of the higher incidence of failure of the hand sewn. Please ask if you have any specific questions. Best, Steve
