Objective: The aim of this study was to obtain estimates of changes in perioperative outcomes and utilization of bariatric surgery in the United States from 1993 to 2016. Background: Bariatric surgery has evolved over the past 2 decades. Nationally representative information on changes of perioperative outcomes and utilization of surgery in the growing eligible population (class III obesity or class II obesity with comorbidities) is lacking. Methods: Adults with obesity diagnosis who underwent primary bariatric surgery in the United States from 1993 to 2016 were identified in the National Inpatient Sample database. Estimates of the yearly number, types and cost of surgeries, patients’ and hospital characteristics, complications and mortality rates were obtained. Prevalence of obesity and comorbidities were obtained from the National Health and Nutrition Examination Survey and changes in utilization of surgery were estimated. Results: An estimated 1,903,273 patients underwent bariatric surgery in the United States between 1993 and 2016. Mean age was 43.9 years (79.9% women, 70.9% white race, 70.7% commercial insurance); these and other characteristics changed over time. Surgeries were exclusively open operations in 1993 (n = 8,631; gastric bypass and vertical banded gastroplasty, 49% each) and 98% laparoscopic (n = 162,969; 69.8% sleeve gastrectomy and 27.8% gastric bypass) in 2016. Complication and mortality rates peaked in 1998 (11.7% and 1%) and progressively decreased to 1.4% and 0.04% in 2016. Utilization increased from 0.07% in 1993 to 0.62% in 2004 and remained low at 0.5% in 2016. Conclusions: Perioperative safety of bariatric surgery improved over the last quarter-century. Despite growth in number of surgeries, utilization has only marginally increased. Addressing barriers for utilization may allow for greater access to surgical therapy.

BACKGROUND: Defining factors associated with remission and relapse of type 2 diabetes (T2D) after Rouxen-Y gastric bypass (RYGB) can allow targeting modifiable factors. We investigated factors associated with T2D remission and relapse after RYGB. STUDY DESIGN: We conducted a retrospective review of consecutive patients with T2D who underwent RYGB between 1993 and 2017. T2D remission was defined as medication discontinuation and/or hemoglobin A1c <6.5%. Relapse was defined as recurrence medication use and/or hemoglobin A1c !6.5%. Independent correlates of T2D remission and relapse were identified using logistic regression. RESULTS: Six hundred and twenty-one patients (aged 46.7 AE 10.6 years; 30% on insulin; BMI 49.8 AE 8.3 kg/m 2) had at least 1-year follow-up. Median follow-up was 4.9 years (range 1 to 23.6 years). Prevalence of T2D remission was 74% at 1 year, 73% from 1 to 3 years, 63% between 3 and 10 years, and 47% beyond 10 years. Ninety-three percent of remissions occurred within 3 years of RYGB, 25% relapsed. Median time to relapse was 5.3 years (interquartile range 3 to 7.8 years) after remission. Higher 1-year percentage total body weight loss, lack of preoperative insulin use, and younger age at operation were independently associated with T2D remission. Preoperative insulin use, lower percentage total body weight loss at 1 year, and greater percentage total body weight regain after 1 year were independently associated with T2D relapse. CONCLUSIONS: This longitudinal retrospective analysis shows that preoperative insulin use and age, 1-year weight loss, and regain after that influence T2D remission and relapse after RYGB. Referring patients at a younger age, before insulin is needed, and optimizing weight loss and preventing weight regain after RYGB can improve the rates and durability of T2D remission.

Holt-Oram syndrome is clinically characterized by morphological abnormalities of the upper limbs and congenital cardiac defects. Although the disease is congenital, the diagnosis may only be made later in life. It is a rare autosomal dominant disorder, caused by a mutation in the TBX5 gene located on chromosome 12, but sporadic cases have also been reported. We describe the case of a 75-year-old man with known morphological alterations of the upper limbs since birth and congenital cardiac defect (atrial septal defect), who later in life also manifested with advanced atrioventricular block.
