Plication of diaphragm minimal invasion?

I have been diagnosed with unilateral (one sided) elevated diaphragm with the recommendation for plication surgery.  The diaphragm is markedly elevated and a picture of it is rather startling.  At one point, my diaphragm is higher than my heart.  I have the usual symptoms related to this condition.  But here's my question: my doctor will not do the surgery using laproscopic techniques.  He feels there are too many vital organs right beneath this rather thin diaphramagtic wall which  could be easily nicked with all the sewing that needs be done.  So he wants to do it "the old fashioned way."   Is his position a valid one?  Or is it just that he doesn't know how to do it using the laproscopic tools?  Has anyone had this surgery done using the laprocopic technique? Thank you.
