OBJECTIVE Limited data on patients undergoing Roux-en-Y gastric bypass surgery (RY-GBP) suggest that an improvement in insulin secretion after surgery occurs rapidly and thus may not be wholly accounted for by weight loss. We hypothesized that in obese patients with type 2 diabetes the impaired levels and effect of incretins changed as a consequence of(More)
BACKGROUND There currently exist several training modules to improve performance during video-assisted surgery. The unique characteristics of robotic surgery make these platforms an inadequate environment for the development and assessment of robotic surgical performance. METHODS Expert surgeons (n=4) (>50 clinical robotic procedures and >2 years of(More)
The mechanisms responsible for the remarkable remission of type 2 diabetes after Roux-en-Y gastric bypass (RYGBP) are still puzzling. To elucidate the role of the gut, we compared β-cell function assessed during an oral glucose tolerance test (OGTT) and an isoglycemic intravenous glucose clamp (iso-IVGC) in: 1) 16 severely obese patients with type 2(More)
We thank Dr. Pontiroli, and agree with his commentary (1). Dr. Pontiroli provides an interesting observation regarding change in b-cell function following weight loss by gastric banding in subjects with type 2 diabetes. His data show minimal improvement in insulin release, as assessed by the Dinsulin/Dglucose during an oral glucose tolerance test (OGTT),(More)
