In a prospective, randomized, multicenter study in patients undergoing laparoscopic gastric bypass procedures (LRYGBP), postoperative complications were reduced from 18 in control subjects to 8 in patients who were preoperatively given a diet of 800 kcal/d for 2 weeks. Surgeons, who were blinded as to who received the diet, also rated the operations as easier in those who received the diet, although operating times were not different between the groups.
To my knowledge, this article1 is the first to provide class I data regarding the benefits of weight loss on early operative outcomes of LRYGBP. The study was correctly designed and controlled, and therefore, the data should be reliable.
