“…The current study added a sixth definition of 15% total weight regain from nadir, in accordance with recommendations to use %TWL when reporting weight loss. A 15% regain of total body weight from nadir has been repeatedly used after RYGB [4,13,18]. In total, the following six definitions were applied: (1) an increase > 10 kg from nadir, (2) an increase > 25%EWL from nadir, (3) an increase in BMI of 5 kg/m 2 from nadir, (4) weight regain to a BMI > 35 kg/m 2 after successful weight loss, (5) any weight regain, and (6) an increase > 15% of total body weight from nadir.…”

“…Many different, arbitrary definitions of weight regain are currently found in the literature [10]. These definitions include, but are not limited to: Bany weight regain,^the percentage of total weight lost at nadir, the percentage of excess weight loss (%EWL), the percentage of weight change from nadir, or a minimum increase in kilograms [3,5,8,[13][14][15][16][17][18][19][20][21].…”

Introduction The prevalence and clinical significance of weight regain after bariatric surgery remains largely unclear due to the lack of a standardized definition of significant weight regain. The development of a clinically relevant definition of weight regain requires a better understanding of its clinical significance. Objectives To assess rates of weight regain 5 years after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), applying six definitions and investigating their association with clinical outcomes. Methods Patients were followed up until 5 years after surgery and weight regain was calculated. Regression techniques were used to assess the association of weight regain with health-related quality of life (HRQoL) and the presence of comorbidities. Results A total of 868 patients participated in the study, with a mean age of 46.6 (± 10.4) years, of which 79% were female. The average preoperative BMI was 44.8 (± 5.9) kg/m 2 and the total maximum weight loss was 32% (± 8%). Eighty-seven percent experienced any regain. Significant weight regain rates ranged from 16 to 37% depending on the definition. Three weight regain definitions were associated with deterioration in physical HRQoL (p < 0.05), while associations between definitions of weight regain and the presence of comorbidities 5 years after surgery were not significant. Conclusion These results indicate that identifying one single categorical definition of clinically significant weight regain is difficult. Additional research into the clinical significance of weight regain is needed to inform the development of a standardized definition that includes all dimensions of surgery success: weight, HRQoL, and comorbidity remission.

“…Roux-en-Y gastric bypass and sleeve gastrectomy are the most common procedures to treat patients with severe obesity both worldwide and in Germany [4,5]. The average percentage of excess weight loss (%EWL) 1 year after surgery is about 70% for gastric bypass [6] and 65% for sleeve gastrectomy [7], but about one-third of patients show failure with < 50% EWL [8] or weight regain in long-term evaluations [9].…”

Background: It is an important condition for adequate weight loss and prevention of adverse events that bariatric surgery (BS) candidates possess good specific health knowledge. There is a paucity of standardized instruments to evaluate the specific health knowledge of patients before and after BS. Therefore, we developed a 32-item multiple-choice test covering the main aspects of life which are important after BS, and investigated the correlation of specific health knowledge with health literacy, level of depression and anxiety, percentage of excess weight loss, and specific complications of BS in postoperative patients. Methods: Two groups participated in the cross-sectional study: the preoperative group (n = 109) was recruited from candidates for BS (gastric bypass or sleeve gastrectomy), the postoperative group (n = 110) was recruited from patients 12-74 months after BS (average 33 months, SD = 16.5). Both groups had completed a preoperative multimodal training program. Specific health knowledge was assessed with a newly developed knowledge questionnaire. Health literacy was evaluated with the short version of the European Health Literacy Survey (HLS-EU-Q16). The 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Scale (GAD-7) were used to assess the levels of depression and anxiety. Results: The pre-and postop-erative group did not differ with regard to the number of correctly answered questions on the knowledge questionnaire, with 75% correct answers in both groups (p = 0.059). No correlations were found with health literacy (p = 0.498) and levels of depression (preoperative group: p = 0.279; postoperative group: p = 0.242) and anxiety (preoperative group: p = 0.866; postoperative group: p = 0.119). In postoperative patients specific health knowledge was not associated with the weight loss achieved (p = 0.437). Conclusion: The newly designed knowledge questionnaire can be useful for screening specific knowledge of BS patients at different time points. associated with better weight loss nor with postoperative complications and do not replace the lifelong practical application of dietary recommendations and physical activity.Further longitudinal studies with knowledge assessment at various time points (before the start of training, before and after the surgery) are necessary for the evaluation of retained knowledge in the same patients over time.

“…Согласно данным проведенных исследований, после обоих видов оперативного вмешательства наблюдаются случаи как неэффективного снижения массы тела, так и повторного набора массы тела (ПНМТ) [5][6][7]. В настоящее время в литературе нет единого определения ПНМТ; большая часть исследователей считают повторным набором массы тела любую прибавку массы тела после точки надир (минимальная масса тела после оперативного вмешательства).…”

Dynamics of body weight and comorbidities in obese patients after sleeve gastrectomy vs. gastric bypass

et al. 2020

Background: Bariatric surgery methods have proven to be most effective in treating obesity. Weight regain (WR) is often found after various types of bariatric surgery. The clinical significance of WR is not clearly defined. Aims: to assess the dynamics of body weight and determine the amount of clinically significant WR based on the study of carbohydrate metabolism and blood pressure in patients with obesity after performing sleeve gastrectomy (SG) and gastric bypass (GB). Materials and methods: 68 patients with obesity after SG (40) and GB (28) were observed for 3 years. Body mass index (BMI), percentage of excess BMI lost (% EBMIL), WR, glycated hemoglobin, blood pressure were evaluated. Results: A comparable efficiency (EBMIL more than 50%) of the SG and the GB was at the nadir point. %EBMIL over 50% was achieved in 78.8% of patients after SG and 80.0% of patients after GB. WR more than 15% was associated with a significant increase in systolic blood pressure. Clinically significant WR in the SG group was detected in 32.5% of patients, in the GB group in 17.2% of patients (p 0.05). Conclusion: WR of more than 15% was associated with a significant increase in systolic blood pressure in patients with obesity after SG and GB, which makes it possible to consider WR of more than 15% clinically significant. A clinically significant WR 36 months after surgery was detected in 32.5% of patients after SG and 17.2% of patients after GB.
