Obesity is a serious health problem in the United States today, and surgical treatment is recognized as long-term effective therapy. Minimally invasive techniques are becoming the “gold standard” approach to the treatment of disease, and robotic surgery has the potential to advance the use and development of minimally invasive procedures. In this article, we report our experience using robotically assisted technology to perform bariatric surgery. From mid 2002 to early 2004, 110 robotically assisted Roux-en-Y gastric bypass and 32 robotically assisted gastric banding procedures were performed at our institution. The mean preoperative body mass index was 46 for the patients receiving Roux-en-Y gastric bypass and 49 for the patients receiving gastric banding. The mean length of stay was 2.1 days and 1 day for patients in the 2 respective groups. There were 3 strictures in the Roux-en-Y group and 1 marginal ulcer in the gastric banding group; no leaks were observed in any patients in either group. There was 1 conversion to a laparoscopic procedure in the Roux-en-Y gastric bypass group. We conclude that robotically assisted bariatric surgery will allow more surgeons to offer patients the same safety and successful outcomes currently available through open techniques but without the significant morbidities of large surgical wounds.
