I think the thing that upsets me the most about this, is that very early in the process the patient ws not informed of the trismus issues, and was not on a program of stretching the muscles of the mouth right from the get go as treatment started, to prevent this issue of not being able open his mouth more. Getting a peg does involve an upper endoscopy which is of course done with an air pump and very bright light so that they can hit the right spot when doing the surgical incision from the outside. Like the trismus, the doctors should have been thinking ahead of the curve and put the PEG tube in long before inflamation in the patients throat and airway issues became present. Mine was put in the second week of treatment (I complained that I didn't need it or want it at that early stage since I could still eat by mouth) but by week four I was unable to eat by mouth and glad it was there. I was on it for 13 months with severe complications from the radiation... something they had no way of knowing my body would respond to in that radical a manner early in the game. So that is why I am such an advocate of the PEG. You don't know how any particular patient is going to react, and if it is severely, it can be too late to put in the PEG unless treatment stops, so inflamation goes down, and that is not a very desireable thing to do. Please post where the treatments are being done at.
