How to Train Surgical Residents to Perform Laparoscopic Roux-en-Y Gastric Bypass Safely

World Journal of Surgery, 05/17/2012

The data suggest that under stringent supervision and with sufficient laparoscopic practice, implementation of LRYGB as part of surgical training is safe and results in only a slightly longer operating time. Complication rates, days of hospitalization, and the rates of readmission and reappearance in the ED within 30 days were similar between the both groups.


  • All patients who underwent LRYGB between March 2006 and July 2010 were retrospectively analyzed.
  • The procedure was performed by a surgical resident under strict supervision of a bariatric surgeon (group I) or by a bariatric surgeon (group II).
  • The primary end point was the occurrence of complications.
  • Secondary end points included operative time, days of hospitalization, rate of readmission, and reappearance in the emergency department (ED) within 30 days.


  • A total of 409 patients were found eligible for inclusion in the study: 83 patients in group I and 326 in group II.
  • There was a significant difference in operating time (129 min in group I vs. 116 min in group II; p < 0.001) and days of hospitalization.
  • Postoperative complication rate, reappearance in the ED, and rate of readmission did not differ between the two groups.
