I quickly switched my mother to disposable pouches. No problems at all. The bags detach and are discarded, 2-3 times/day. Right after surgery we had some overnight problems because residual gas in the GI system blew up the bags but that stopped quickly. The folks at Convatec (including nurses) were incredibly helpful, and had more up to date info than our stoma nurse. The pouches we used were tan with a window, but they come without a window. I also used Ease strips which were stuck along the sides of the barrier and added additional strength and seal.
