The RYGBP is the most commonly performed bariatric procedure in the United States.1 Furthermore, there are numerous studies documenting both short-term and long-term outcomes.2- 12 These studies, listed in Table 1, collectively suggest that open RYGBP results in a hospital stay ranging from 4 to 8 days, a perioperative complication rate of 3% to 20%, a mortality rate of 0% to 1%, a pulmonary embolus rate of 0% to 3%, a leakage rate of 0% to 5%, and a hernia rate of 5% to 28%. Operative time and hospital stay were not reliably reported in most studies. Long-term weight loss at 5 to 15 years seems to be 49% to 77% of excess body weight. Most comorbidities including hypertension, sleep apnea, osteoarthritis, type 2 diabetes mellitus, and gastroesophageal reflux are improved or resolved and the quality of life is significantly improved. Late complications may include marginal ulcer, bowel obstruction, and anastomotic stricture. Late nutritional deficiencies are a consequence of the foregut bypass and include iron deficiency anemia (up to 47%), vitamin B deficiency (up to 40%), folate deficiency (up to 18%), and other micronutrient deficiencies.14 Most of these nutrient deficiencies can be circumvented by adequate dietary supplementation. Protein malnutrition, however, is not a recognized complication of RYGBP. It is against these benchmarks that all bariatric operations, laparoscopic or open, should be judged.
