Each new appliance was supposed to last 5-7 days...mine would last about a day and a half, sometimes 2 days during the first couple months. By trying different techniques we were able to get it to last about 4 days by the end, thank goodness. At the beginning, my skin was getting raw all around the stoma (the actual opening) from using the various wipes, adhesive and powder.
This is what was used each and every time the appliance needed changed.
I'll warn you now...the next picture is pretty gross. It's a picture of my actual stoma with nothing on it. I took the picture when I was changing the appliance. This picture was taken after having the colostomy for about 5 months, so my skin was not too raw all around it anymore.
Okay, this is enough for one day.
