This is a massive, 262 page report for physicians, with several hundred references, and considerable government bafflegab built in..  It was compiled by an all-star panel of physicians, but with few, if any, surgeons among them.  This report will become a standard reference.

This report was sponsored by the insurance industry, and prepared by a Medical Advisory Panel which was heavily laden with insurance executives from the Blues, and from Kaiser..  It does acknowledge the value of bariatric surgery in a tentative way, while determining that laparoscopic procedures have not been adequately evaluated for safety.  The criteria for inclusion, and for this decision was, in my opinion, excessively stringent, demanding a standard which is essentially impractical, if not impossible, to meet.  It is likely that the insurance industry will use this report to deny coverage for many procedures.

Our paper on our first 500 Laparoscopic cases was included among the 6 that were considered.  We reported 500 consecutive cases, and that report included the first 5 cases of Laparoscopic Gastric Bypass performed worldwide.  We had very acceptable complication rate, and no mortality.  We also demonstrated a 96% reduction of major co-morbidities.
