This randomized clinical trial assesses the efficacy and safety of standard gastric bypass vs distal gastric bypass in patients with a BMI of 50 to 60.
This study examines whether gastric bypass surgery is equally effective in reducing mortality in groups undergoing surgery at different ages.
This survey study examines patients’ self-reported presence and severity of symptoms and quality of life after Roux-en-Y gastric bypass surgery.
This article reviews a cost-performance feedback tool to provide surgeons with a continuous assessment of operating room expenditures to increase surgeons’ awareness of costs and encourage changes in behavior.
This cohort study reports that bariatric surgery increases the chance for remission of type 2 diabetes mellitus.
This cohort study compares the 5-year efficacy of gastrointestinal metabolic surgery vs medical treatment for type 2 diabetes mellitus in mildly obese patients.
This randomized clinical trial reports that bariatric surgery with 2 years of an adjunctive low-level lifestyle intervention resulted in more disease remission than did lifestyle intervention alone for obese participants with type 2 diabetes mellitus.
This interrupted time series with comparison series study reports that laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass were associated with flattened total health care cost trajectories but Roux-en-Y gastric bypass patients experienced lower total and prescription costs by 3 years postsurgery.
This randomized clinical trial reports that in patients with a body mass index of 50 to 60 kg/m2, duodenal switch resulted in greater weight loss and greater improvements in low-density lipoprotein cholesterol, triglycerides, and glucose 5 years after surgery compared with gastric bypass while improvements in health-related quality of life were similar.
The authors of this retrospective cohort study and modified Delphi procedure developed a list of procedure codes to identify high-risk surgical procedures in claims data.
This retrospective cohort study found that Roux-en-Y gastric bypass resulted in greater weight loss than adjustable gastric banding but a higher risk of short-term complications and long-term subsequent hospitalizations. See also the Invited Commentary by Dimick and Finks.
Thereaux et al assess the safety of revision procedures by comparing the 30-day outcomes of primary gastric bypass vs revisions following failed adjustable gastric banding. They performed a retrospective review using logistic regression models to compute odds ratios across preoperative body mass index quartiles. See the Invited Commentary by Gagner.
