Weight training with a colostomy bag?

[Kieran R]

My father (55) who is moderately active, has expressed interest in strength training and the starting strength model would be appropriate. However, due to cancer surgery a number of years ago he has a permanent hole in his abdominal wall for a colostomy bag. Is it safe to train with this sort of thing, as it's possible to herniate under stress? Have you ever experienced training a client with a permanent or even temporary ostomy bag?
Thanks for your time.

This is out of my realm of expertise. We'll ask.
