Comparative Study Observational StudyThe impact of bariatric surgery on retinopathy in patients with type 2 diabetes: a retrospective cohort study.
The impact of bariatric surgery on diabetic retinopathy (DR) is unclear. DR might improve after surgery because of improvement in DR risk factors, but the rapid improvement in hyperglycemia after surgery could worsen DR. ⋯ After bariatric surgery, patients with T2DM remain at risk for developing STDR, even those who did not have evidence of DR before surgery. However, surgery was associated with a lower progression to STDR or maculopathy compared with routine care. Randomized clinical trials are needed to ascertain the impact of bariatric surgery on DR.

Influence of intraoperative hypotension on leaks after sleeve gastrectomy.
Leak after a sleeve gastrectomy (SG) is a severe complication. Risk factors, such as regional ischemia, increased intraluminal pressure, technical failure of the stapling device, and surgeon error, have been reported. ⋯ Intraoperative hypotension may contribute independently to a leak after SG.

Multicenter StudyInternal herniation after laparoscopic antecolic Roux-en-Y gastric bypass: a nationwide Danish study based on the Danish National Patient Register.
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the most common surgical treatment for morbid obesity in Denmark. Internal herniation (IH) or intermittent internal herniation (IIH) is a major late complication after LRYGB due to persistent mesenteric defects. However, the incidence of IH/IIH is still not known in Denmark. ⋯ In the period from 2006 to 2011, mesenteric defects were not routinely closed during LRYGB in Denmark. The cumulative 5-year incidence of IH/IIH after LRYGB was 4% in a median follow-up period of 38 months (range 16-87) in Denmark when data was retrieved from the NPR.

Relationships between type 2 diabetes remission after gastric bypass and different weight loss metrics: arguments against excess weight loss in metabolic surgery.
Percentage excess weight loss (%EWL) outcome of bariatric surgery is distorted by deviations in baseline body mass index (BMI). It has been reported that this can lead to false conclusions, most likely because bariatric weight loss in fact is baseline-BMI independent. ⋯ In T2DM patients, weight loss after gastric bypass does not depend on BMI, HbA1c, or T2DM medication at baseline. The popular %EWL metric and the 50 %EWL success criterion are problematic in comparing bariatric and metabolic outcome of gastric bypass surgery. They should be abandoned. The %WL metric is the best and most commonly used alternative, whereas %AWL is ideal for selected logistics in bariatric research. Weight loss percentiles are best suited for defining bariatric success in metabolic surgery.
