Thanks for all the replies. The different opinions on PEG versus naso-gastric gave me lots of "food" for thought. (Sorry, bad pun.) The doctor is going to start him out without any kind of tube and reevaluate weekly or even daily. If and when he needs one inserted, it will be done immediately. I suppose that is one of the advantages of being at Cleveland Clinic; when something needs done, it happens very quickly! I was amazed when we went for workups on Tuesday, and the doctor had the results of his blood test and chest x-rays when we saw him just 30 minutes later. That is probably the norm for large hospitals, but it was new to us. The thought of a naso-gastric tube had me apprehensive at first, but after reading your replies, I feel reassured that it will be doable, if necessary.
