If a person dies with a colostomy bag, how should he be washed and shrouded given the continuous discharge, should he be washed and buried with the bag, and will the bag burst as the body decomposes?

The deceased is honored by removing any impurities from them, which is done by taking off waste drainage bags and gently pressing their abdomen to expel whatever is ready to come out. Then, the exit is sealed with something that prevents the remaining waste from coming out, such as cotton, pure clay, or available medical means.
