Chronologic evolution of variables associated with laparoscopic gastric bypass. Basis for bariatric surgery training standardization at Hospital Domingo Luciani

Abstract

Bariatric surgery is one of the specialties of mayor growth in last years. Objective: Characterize the laparoscopic gastric bypass learning curve. Methods: Retrospective study, of a prospective maintain date of base, with the first 300 obese patients operated, between august 2008 and july 2011 at Hospital Domingo Luciani, Caracas, Venezuela. All surgeries were perform by the author. Operative time, complications, mortality, reoperations, and conversions to open surgery were analyzed. Results: The minimal operative time was obtain after the 75 case, being between 70 to 110 min after that. Complications were around 5% after that number. There were two conversions to open surgery, and four reoperations, along the experience presented. Mortality was 0. Conclusions: Characterizing the learning curve, allows the development of training programs adapted to the reality of each center, so that the student skills acquirement does not affect the patient’s evolution .
