Hi, I've been lost for some time, but I must say that it is temporary, not definitively. It is just for personal reasons, once solved I'll be back as "old times". Nevertheless, I've been reading almost all the messages you've sent.
My problem is this: I must write a surgical article titled " Laparoscopy in the staging of the abdominal cancer " or something like that. I'd like you to help me in where I may find bibliography.
