Has anyone in this forum had previous experience in a Diagnostic Laparoscopy ?

This procedure was performed upon me 3/29/11 in order to finally preclude/exclude any possible tumour on/in my liver. 5 MRIs since 2010 showed no enlargement but also no apparently discernible 'object'(?). It seems to 'exist' in scans, but not in reality.Portals for cameras were inserted and a biopsy taken. All up about 4 holes excised/cut and still nothing to be found. My best mate reckons it's just my evil twin mucking with their heads but the pain he has inflicted upon me over the past 7+ years has left me sceptical in this regard. They booted me out with 20 Endone and invited me back in 6 months time for another 3-hour cruise. Has anyone else here been in a similar movie or read the same book. I would dearly love to hear any/all responses from other...humans.
