I'm sorry to report that I too had difficulties with a temporary diverting loop ostomy. I think it's the loop that is the problem...something to do with tension. Mine retracted to the point that it disappeared. They did a revision which helped with the retractions (and ongoing obstructions) but then I experienced ridiculous prolapsing. Again, I think the loop is the problem vs an end ostomy. My first ostomy (between the colectomy and take down) was problem free and I think it must have been a loop as well so who knows? I hope for a good outcome for you.
