Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery.More infoBACKGROUND: The remission rates of type 2 diabetes mellitus (T2DM) after Roux-en-Y gastric bypass (RYGB) vary according to the glycosylated hemoglobin A1c (HbA1c), fasting blood glucose (FG), and medication status. Our objectives were to describe remission using the American Diabetes Association standards for defining normoglycemia and to identify the factors related to the preoperative severity of T2DM that predict remission to normoglycemia, independent of weight loss, after RYGB. The setting was an urban not-for-profit community hospital. METHODS: We performed a retrospective analysis of prospectively collected data from a cohort of 2275 patients who qualified for bariatric surgery (2001-2008). Five different models for defining remission (no diabetes medication and a FG
- Celaya, M. P. (2010). Psychological classification as a communication and management tool in obese patients undergoing bariatric surgery.. Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery.More infoBACKGROUND: Psychological evaluations are used to ascertain patient suitability for bariatric surgery and to challenge their ability to comply with therapy. The modern paradigm of obesity includes a neurobiologic component working in parallel with the limbic system of appetite and reward. To achieve the goals of surgery, an evaluation of the psychological fitness of the patient is often included in the clinical pathway. We present a psychological classification system with the goal of integrating the psychological factors into patient treatment. METHODS: All patients (Roux-en-Y gastric bypass, n = 1814; laparoscopic adjustable gastric banding, n = 589) were evaluated using psychological testing/interview and assigned to groups 1-4 before surgery. The group 1 patients (n = 788; 32.8%) did not necessitate intervention, group 2 (n = 1110; 46.2%) were requested to attend the support group, groups 3A (n = 394; 16.4%) and 3B (n = 111; 4.6%) required intervention to continue to surgery, and group 4 patients were not recommended for surgery. The main outcome measures, including complication, readmission, and reoperation rates, were analyzed for differences among the psychological groups. RESULTS: After comparing the outcome measures between each classification, no significant differences were found in the major complication rates, readmissions, reoperations, or length of stay among the groups. Groups 3A and 3B were able to achieve similar rates of success, despite their psychosocial impairment at the initial evaluation. CONCLUSION: The assignment of a psychological classification can facilitate bariatric team recognition of the unique psychological factors that affect the success of surgery. Assessing the patient's psychological composition and addressing potential psychosocial barriers before surgery can increase the positive long-term outcomes and reduce the incidence of complications after bariatric surgery.
- Celaya, M. P. (2009). Metabolic acuity score: effect on major complications after bariatric surgery.. Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery.More infoBACKGROUND: Co-morbid conditions in obese patients contribute to the incidence and severity of major complications after bariatric surgery and significantly increase the cost of the procedure. Previous publications have validated the patient factors that increase the risk of mortality; however, it is currently a rare event. The development of a metabolic acuity score (MAS) to augment the body mass index might allow for accurate preoperative assessment and optimal treatment of patients. The present study has proposed a MAS for decreasing major complications. METHODS: Prospectively collected outcomes of 2416 patients undergoing Roux-en-Y gastric bypass (n = 1821) or laparoscopic adjustable gastric banding (n = 595) in a community hospital were evaluated for the incidence of major complications, readmissions, and reoperations. Beginning in August of 2006, 1072 patients were divided into MAS groups of 1-4 according to age, body mass index, weight, history of deep vein thrombosis/pulmonary embolism, sleep apnea, diabetes, hypertension, immobility, heart disease, and psychological classification. The acuity groups were compared with each other and with 1344 patients who underwent treatment before the MAS was implemented. RESULTS: A significant decrease occurred in the readmission rates within 30 days after the MAS was put into practice (8.5% before MAS versus 1.7% after MAS, P
