Before my surgery, I watched a lot of YouTube videos of people showing how to change there osotmy bags and I thought...."wow, there sure is a lot of stuff needed". Come to find out that isn't the case for me. When I was having skin issues from leakage, I too was using "alot of stuff" but once I went back and consulted with a WOC nurse, she took one look at my situation and said "Oh, I can fix that" and she did. Just an Adapt Barrier ring, a convex bag and a warm wash cloth to get the adhesive off when I chang is all I use. It literally takes me less than 10 minutes and I'm on my way.
Recently I joined the local Ostomy Support Group in my area and I am learning so much for those veterens. One gal there has had her ileo for 42 years and boy the stories she tells. Things are so much better now.
Keep in mind that everyone is different....different body types, different lifestyles, etc. so getting good information goes along way to finding what works best for you regardless of how much "stuff" it takes.
