I too prefer Hollister's New Image pouch, so I was reluctant to have to switch products when my skin troubles began. However, I found a great compromise and didn't have to. The various companies all sell a product called a barrier - it's a square shaped piece of material, the same size as the wafer, with an adhesive on on side. They use a different adhesive from the one used on the wafer. Wafer goes on barrier, barrier goes on skin, and you can use whatever pouching system you want without it having to touch your skin. Then you just hope that you don't end up allergic to the adhesive on the barrier, haha. Although I use a Hollister pouch, I use a Coloplast barrier. Coloplast prides themselves on having the most hypoallergenic products out there, so is probably your husband's best bet.
Diagnosed with UC in 2007
Flare in 2007 causing anemia requiring blood transfusions, eventually controlled by asacol and 6-MP.
Flared again in 2009 as 6-MP lost effectiveness, went on TPN and received more blood. Started Remicade, which induced remission.
Flared 2010; Remicade no longer effective.
Had 1st surgery of 3 step j-pouch at CC on 1/19/11. 2nd slated for April, and j-pouch in July!
