Our Assessment of Obesity-related Metabolic Comorbidities (AOMC) scoring tool combines pharmacotherapy and biochemical data to objectively define type 2 diabetes (T2D), hypertension (HTN), and dyslipidemia (DYS) severity. We previously showed that AOMC more accurately describes disease severity than clinical history alone. We aimed to show that AOMC more precisely and reproducibly measures metabolic disease response to RYGB and preoperative disease severity influences remission rates. University hospital, United States. AOMC scores for T2D, DYS, and HTN were calculated preoperatively and postoperatively (1-, 2-, and 5-years) for patients who underwent RYGB over 14 years. Generalized linear mixed-effect models were used to evaluate AOMC score trends and remission over time. Of 351 patients, 214, 188, and 303, presented with any T2D, DYS, or HTN respectively. One-year remission rates were: T2D 57.1%, DYS 59.7%, and HTN 29.3%. Over 5 years post-RYGB, remission rates declined for T2D ( < .05) and DYS ( < .05) but remained steady for HTN ( > .05). Remission was associated with preoperative disease severity: those with premetabolic disease had the highest remission rates (i.e., 1-year: pre-T2D 81.4%, pre-DYS 91.4%, pre-HTN 53.5%, all < .05), while those with most severe scores preoperatively (untreated/uncontrolled) had the lowest remission rates. AOMC allows precise assessment of comorbidity severity and disease-specific postoperative quantification of comorbidity responses and remission rates. These findings can guide preoperative metabolic disease optimization and postoperative metabolic recovery expectations and standardize communication regarding comorbidity severity.","PeriodicalId":49462,"journal":{"name":"Surgery for Obesity and Related Diseases","volume":"43 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To retrospectively analyze early outcomes (≤30 d) after anastomotic MBS with planned SDD (≤12 hr). University Hospital, Canada; Public Practice. SDD anastomotic MBS were proposed with strict preoperative criteria and included single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), and single-anastomosis sleeve ileal bypass (SASI). Enhanced recovery after bariatric surgery protocols and post-anesthesia care unit criteria were followed. Unplanned overnight stay, emergency department (ED) visit, readmission, morbidity-mortality, and reintervention rates were analyzed. Since 2021, 208 patients (191 female and 17 male) have undergone SDD anastomotic MBS, with 76% conversion procedures: 92 SADI-S, 72 RYGB, 35 OAGB, and 9 SASI (mean age = 41.4 yr and mean preoperative body mass index = 41.9 kg/m). Unplanned overnight stays and ED visits were 4.8% and 4.3%, respectively. Readmission rate was 5.8% (5 SADI-S, 5 RYGB, 1 OAGB, and 1 SASI). Overall morbidity rate was 14.9%, including 3.9% major complications. Within 30 days postoperatively, there were 2 duodenal leaks, 1 intrabdominal collection, 1 common bile duct stenosis, and 1 acute appendicitis in the SADI-S group. There were 2 occlusions on the jejunojejunal anastomosis and 1 bleeding on the gastrojejunal anastomosis in the RYGB group. Five (2.4%) required reintervention with no mortality.

This nationwide observational population-based cohort study analyzed data from the French National Health Insurance database. It included all patients who had undergone primary SG and AGB in France between January 1, 2012, and December 31, 2014, and followed until December 31, 2020. The study assessed LLT reimbursement evolution and costs across 4 different CMBS sequences. During follow-up, 6396 patients underwent the 4 CMBS sequences: SG-RYGB (Roux-en-Y gastric bypass) (n = 2400), AGB-SG (n = 2277), AGB-RYGB (n = 1173), and SG-SG (n = 546), with a rate of LLT reimbursement of 9.8%, 3.6%, 6.6%, and 7.9%, respectively, in the year before CMBS. The rates of discontinuation of treatment at 2 and 4 years were 41.9%, 35.4%, 45.6%, 20.5% and 45.6%, 31.3%, 64.3%, 31.6%, respectively. At 4 years, the median [interquartile range] annual costs (euros) per patient were significantly lower ( < .01) than the costs in the year before CMBS for each sequence: 86.8 [57.3; 136.1] versus 38.0 [.0; 64.6], 79.1 [50.5; 120.1] versus 50.4 [15.6; 64.1], 89.0 [66.5; 139.6] versus .0 [.0; 58.8], and 89.8 [66.1; 121.4] versus 63.1 [.0; 93.4].

However, many patients do not attend postsurgical appointments with the bariatric team, which may contribute to poor surgical outcomes. This study sought to understand sociodemographic factors related to follow-up appointment attendance and weight outcomes. The first objective was to determine whether there was a relationship between 1-year follow-up appointment attendance and sociodemographic factors. The second objective was to determine whether patients from certain sociodemographic groups were more likely to attend a 2-year follow-up appointment. The third objective was to determine whether there were differences in weight outcomes for patients who attended follow-up appointments compared with those who did not attend. University hospital, United States. This study was a retrospective observational study. Participants included 841 adult patients who underwent bariatric surgery, of whom 505 (60.05%) attended a 1-year appointment with the bariatric team (348 attended a follow-up visit with another medical provider), and 398 (47.32%) who had any follow-up medical visit at 2 years after surgery. Sociodemographic variables were collected during a presurgical psychological evaluation. Weight-related variables were obtained through patients’ electronic medical records 12 and 24 months after surgery. Younger patients and those with lower education levels were less likely to attend the 1-year follow-up appointment with the bariatric team. People who attend 1-year follow-up with bariatric team have more favorable weight outcomes at 1 year and 2 years after surgery. Follow-up appointment attendance with the bariatric team may be a critical factor in the effectiveness of bariatric surgery. Bariatric surgery teams should employ strategies to increase attendance at the 1-year follow-up visit with the surgical team. Additional strategies should be enacted to increase follow-up appointment attendance for patients with lower education levels.","PeriodicalId":49462,"journal":{"name":"Surgery for Obesity and Related Diseases","volume":"6 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
