Every time your father has surgery to repair the leak it is a shock to his intestine and it won't absorb as much as it should (causing high-output). As his intestine heals then his output should decrease, but that takes weeks. It seems that they keep having to operate and it shocks his system preventing him from healing and starting the cycle all over again.
If that was his final surgery then the output should start to decrease soon. Has there been any decrease in output (on a daily or weekly basis)?
If there is no improvement then maybe you can get him transferred to another hospital that specializes in GI surgeries. I went to NYP Cornell in NYC, they had patients that traveled from all over the world to treat their severe issues.
