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

@entity1 @entity28
BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is currently considered the gold standard treatment for morbid @entity28 . 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. METHODS: The data was collected prospectively. All @entity1 with primary LRYGB between March 2006 and April 2014 were included. Only @entity1 with full data on demographics, length of stay, operating time, and complications were included in the study. RESULTS: Five hundred and eleven @entity1 underwent a LRYGB. Ninety five of them underwent a redo RYGB (conversion), and were excluded. Of the remaining 416 @entity1 , full data was available for 326 and the statistical analysis refers to this group. The complication rate was available for all @entity1 who were included in the study. The mean age and body mass index were 43 years (14-76 years) and 42.8 kg/m2 (34-76) respectively. The mean duration of surgery was 86 minutes (40-420). In the first 100 @entity1 , operating time was 148 min, while in the last 125 @entity1 it was 75 min. The major perioperative complication rate was 7.7%. Of 4 leaks (0.95%, 3 were encountered in the first 100 operations, and one in the following 316 (3% and 0.3% respectively). The mean length of stay was 2.2 days (1-46). None of the @entity1 stayed in the intensive care unit. There was no mortality. CONCLUSIONS: LRYGB is very safe. We confirm that the learning curve for this procedure is more than 100 cases. Appropriate training is crucial.
