[Learning curve in laparoscopic Roux-en-Y gastric bypass for the treatment of morbid obesity].

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is currently considered the gold standard treatment for morbid obesity. The learning curve for this procedure is about 100 cases, and it is considered the most important factor in decreasing complications and mortality. We present our experience and learning curve with LRYGB.

Laparoscopic conversion of failed silastic ring vertical gastroplasty (SRVG) and vertical banded gastroplasty (VBG) into biliopancreatic diversion (BPD).

Background: The Silastic ring vertical gastroplasty (SRVG), a newer modification of Mason's vertical banded gastroplasty (VBG), was the restrictive procedure of choice for many bariatric surgeons before the advent of the laparoscopic adjustable gastric banding. However, a high rate of reoperations for failure and severe complications was reported in long-term studies. Around 50% of the patients underwent conversion to other bariatric procedures.
