enema

Q:

1. Does an enema make ghusal waajib?

2. Does inserting a finger into the anal passage make ghusal waajib?

3. Liquid is inserted into the colon via an enema. The liquid is held in for a prescribed time and then expelled, generally with a bowel movement. If oil is used in the enema, then it is common for small amounts of fluid to leak from the colon and anal passage out of the anus. This may continue for several hours.  Underwear and the area around the anus is generally soiled with this leaking fluid. What is the status of this fluid? Is it in the category of stool?
