Stoma always changing its size due to peristalsis.
Dermacol has turtle neck made of soft stretchable silicone, so it will accommodate peristalsis. Unfortunately Dermacol made for round stomas or almost round. So if your stoma is oval D is not for you.
My stoma is oval shaped but a trick I do ( I use ConvaTec moldable barriers) is I slightly pull up on the skin above my stoma till it's round and then stick down my barrier and it works like a charm :)
