Abstract
This review is aiming to discuss the bariatric surgery outcomes. The present review was conducted by searching in Medline, Embase, Web of Science, Science Direct, BMJ journal and Google Scholar for, researches, review articles and reports, published over the past years. Books published on bariatric surgery outcomes. If several studies had similar findings, we randomly selected one or two to avoid repetitive results. Based on findings and results this review is Charges and comorbidities were greatest in African Americans and Hispanics compared to Caucasians. Medicare and Medicaid-insured patients have higher LOS, charges, comorbidities, morbidity, and mortality compared to privately insured and self-pay patients. Lower income patients have higher LOS and total charges. Nonteaching hospitals have an increased LOS and charges and treat patients with more comorbidities compared to teaching hospitals. Centers of excellence performed substantially more operations than non-designated centers. Despite this, outcomes were equivalent at centers of excellence and hospitals without this designation. Volume-outcome modeling attempting to identify the optimal number for a minimum volume threshold for bariatric operations revealed that annual procedure volume has a weak effect on outcomes.
