J tube removal issues: Anyone have a fistula?

I recently had a j tube placed and it became dislodged and was just causing all kinds of issues so the doctor thought it was best to remove it and use TPN instead. Before the removal, the incision that was used to place the j tube opened up and was having a lot of drainage which is what lead to the removal. The incision still has not closed and it's been 10 days and every time I drink anything (on liquids only) the drainage increases. Has anyone had a similar issue? how long did it take to close up? The drainage is so bad I have to wear an ostomy bag.
