Background: While the number of research publications related to bariatric surgery have increased remarkably in the past decade, research efforts remain uncoordinated and have limited focus, and numerous important questions remain unanswered.
Objective: To generate a research agenda in bariatric surgery.
Setting: National survey.
Methods: The membership of the American Society of Metabolic and Bariatric Surgery (ASMBS) was asked to submit research questions needed to advance the field of bariatric surgery. An expert panel grouped and collated submitted questions and redistributed them back to the membership to rate their importance on a 5-point Likert scale using a 3-round modified Delphi methodology. The top research questions were determined based on provided rankings.
Results: Two hundred ninety-two research questions were initially submitted that were collapsed to 59 unique questions. The ratings for the top 40 questions ranged from 2.67-4.33 (overall mean, 3.46). The highest-ranked questions centered on the mechanisms of effectiveness of bariatric surgery for weight loss and diabetes resolution, the underlying etiology of weight recidivism, and predictors of success.
Conclusions: A research agenda for bariatric surgery was developed using the Delphi methodology. This research agenda may enhance the ability of investigators and funding organizations, including the ASMBS, to focus attention to areas most likely to advance the field, and by editors and reviewers to assess the merit and relevance of scientific contributions.

Department of Surgery, Center for Endocrinology, Diabetes and Metabolism, Children's Hospital Los Angeles and Keck School of Medicine of USC, Los Angeles, CA, USA.
Background: Classic congenital adrenal hyperplasia, primarily due to 21-hydroxylase deficiency, leads to impaired cortisol and aldosterone production and excess adrenal androgens. Lifelong glucocorticoid therapy is required, often necessitating supraphysiological doses in youth to manage androgen excess and growth acceleration. These patients experience higher obesity rates, hypertension, and glucose metabolism issues, complicating long-term health management.

Background: Earlier evidence indicated that metabolic and bariatric surgery (MBS) may adversely affect neonatal outcomes among patients conceiving soon after MBS, but recent studies demonstrated conflicting results, especially for new surgical techniques.
Objectives: The aim of this study was to assess the effects of MBS types and surgery to birth interval on maternal, birth, and nonbirth outcomes in women with severe obesity.
Setting: New York State's all-payer hospital discharge database (2008-2019).
Background: Transumbilical single-port sleeve gastrectomy (SPSG) is a minimally invasive bariatric surgery that offers cosmetic benefits. However, the procedure's feasibility in patients with higher BMI or taller stature remains debated. This study evaluates the outcomes of SPSG based on patient height and BMI.
