Thank you for choosing DoctorSpring.
Sorry to hear about your mother's illness. I understand your concern.
I am of the opinion that the decision of two stage surgery is correct and carries low life risk, in view of obstructive diverticulitis stricture and presence of rectovaginal fistula.
But during first stage it had to be made sure that the stricture part and rectovaginal fistula part is well corrected.
Colostomy can be managed easily. .similar to ileostomy. ..as u you will be already knowing how to manage an ileostomy.
After the first surgery patient can expect good clinical improvement and hence the second surgery should uneventful.
Single stage surgery will carry high risk of leak from intestine joining site leading into infection and sepsis.
I strongly recommend two stage procedure for your patient.
All the best for surgery
Hope this helps
