Dr A. Oliaro (Torino, Italy): You have reported 5 plications of the diaphragm for phrenic nerve involvement. In the Torino experience, we never suture the phrenic nerve after resection, because we don’t believe in suture of the phrenic nerve. But last month, we resected the nerve and we sutured the nerve, and the phrenic nerve now functions; the diaphragm is functional. What do you think about that? Is it necessary to have a study if we must suture the nerve or we cut the nerve and we plicate the diaphragm?
