I have had a colostomy for 3 years. I use the Convatec wafers and bags. They have worked so well with no leakages. After a few days the wafer wax does tend to melt onto the skin but then I change to new one. It is not easy. I have had 5 surgeries-two hernia; 1 twisted colon surgery; two bowel obstructions; still have a large parastomal hernia. But you just move on and do your best.
