Many , many thanks to those who posted their best wishes. David went through his surgery at lunchtime. They had to make quite an incision in his lower torsoe, and discovered his appendix had become 'fused' to his bowel. The surgeon removed his appendix, but with his skill ( I believe ) he was able to sever the fusion, without harm to the bowel. Was heavily sedated with Morphine when we visited, but in his conscious moments, rest assured I passed on the best wishes of those members who posted. Many thanks again, Paul. Cheers folks :)
