Metabolic changes after maternal bariatric surgery may affect subsequent fetal development. Many relevant perinatal outcomes have not been studied in this postoperative population, and the risks associated with short operation-to-birth (OTB) intervals have not been well examined. ⋯ Infants of mothers with a previous bariatric operation had a greater likelihood of perinatal complications compared with infants of NOMs. Operation-to-birth intervals of less than 2 years were associated with higher risks for prematurity, NICU admission, and SGA status compared with longer intervals. These findings are relevant to women with a history of bariatric surgery and could inform decisions regarding the optimal timing between an operation and conception.

Growing consensus suggests that frailty-associated risks should inform shared surgical decision making. However, it is not clear how best to screen for frailty in preoperative surgical populations. ⋯ The RAI-C and RAI-A represent effective tools for measuring frailty in surgical populations with predictive ability on par with other frailty tools. Moderate correlation between the measures suggests convergent validity. The RAI-C offers the advantage of prospective, preoperative assessment that is proved feasible for large-scale screening in clinical practice. However, further efforts should be directed at determining the optimal components of preoperative frailty assessment.

Severe obesity affects 4% to 6% of US youth and is increasing in prevalence. Bariatric surgery for the treatment of adolescents with severe obesity is becoming more common, but data on cost-effectiveness are limited. ⋯ Bariatric surgery incurs substantial initial cost and morbidity. We found that surgery could be a cost-effective treatment for adolescents with severe obesity if assessed over a time horizon of 5 years. Our study underscores the need for long-term clinical trials in adolescents with at least 5 years of follow-up data that capture financial and quality-of-life end points.
