Show morePurpose More medication-related issues are seen with the growing demand for bariatric surgery, because of possible altered pharmacokinetics after surgery. Collaboration with a pharmacist could improve the short- and long-term safety and efficacy of pharmacotherapy in patients undergoing bariatric surgery. The aim of this study was to evaluate the impact of a structured medication review to identify medication-related risks before bariatric surgery.Materials and Methods The impact on pharmacy-led interventions of introducing a structured medication review was evaluated in a historically controlled study. In the retrospective part, we evaluated patient characteristics, medication use, and number of pre-surgery consultations with a pharmacist before the introduction of medication reviews. A flowchart was developed to detect the use of medicines with risks associated with bariatric surgery. In the prospective part, we evaluated pharmacy-led interventions after the introduction of structured medication reviews using the flowchart. Outcome effectiveness was measured through the number of pre-surgery pharmacy-led interventions.Results Before using the flowchart for screening on risk medicines, 40 (2.6%) pharmacy-led interventions were identified in 1536 patients. In the prospective group, 195 patients were included and 88 (45%) interventions were identified (p < 0.001).Conclusion A structured medication review before bariatric surgery significantly increased the number of pharmacy-led interventions in bariatric surgery patients. This procedure will shift interventions to pre-surgery instead of post-surgery, contributing to the optimization of pharmacotherapy at an early stage. Show less

Show moreSparse information is available on pharmacokinetic changes of drugs over time after bariatric surgery. By reviewing the literature on the short- and long-term pharmacokinetic changes of drugs, several patterns were identified for 39 drugs. No relevant pharmacokinetic changes were identified for roughly a third of the drugs. Of the remaining drugs, levels were variable and partly unpredictable shortly after the surgery. In the long term, most of the drug levels remain altered, but in some cases they returned to preoperative values. Based on the changes and the efficacy-safety balance of each drug, clinicians may need to perform additional clinical monitoring for specific drugs, including measuring drug levels. This review provides suggestions for clinicians and pharmacists for specific time-dependent drug dosing advice. Show less

Show moreIntroduction Patients living with psychiatric illnesses (PIs) have a high prevalence of obesity. In a 2006 survey, 91.2% of professionals in the bariatric field identified "psychiatric issues" as clear contraindications to weight-loss surgery. Methods This retrospective matched case-control study investigated the impact, safety, and possible relapse after bariatric metabolic surgery (BMS) in patients with PIs. Also, we tested the incidence of patients who developed PI after BMS and compared the post-procedural weight loss with that in a matched control group without PIs. The cases were matched in a ratio of 1:4 to the control patients standardized for age, sex, preoperative BMI, and type of BMS. Results Of 5987 patients, 2.82% had a preoperative PI; postoperative de novo PI was present in 0.45%. Postoperative BMI was significantly different between the groups when compared to preoperative BMI (p < 0.001). Percentage of total weight loss (%TWL) after six months was not significantly different between the case (24.6% +/- 8.9) and control groups (24.0% +/- 8.4, p = 1.000). Early and late complications were not significantly different between the groups. The psychiatric drug use and dosage changes did not differ significantly pre- and postoperatively. Of the psychiatric patients, 5.1% were postoperatively admitted to a psychiatric hospital (p = 0.06) unrelated to BMS, and 3.4% had a prolonged absence from work after surgery. Conclusion BMS is an effective weight loss treatment and a safe procedure for patients with psychiatric disorders. We found no change in the patients' psychiatric status outside the usual disease course. Postoperative de novo PI was rare in the present study. Furthermore, patients with severe psychiatric illness were excluded from undergoing surgery and, therefore, from the study. Careful follow-up is necessary to guide and protect patients with PI.

Show moreBackground Insufficient weight loss or weight regain has been reported in up to 30% of patients after laparoscopic sleeve gastrectomy (LSG). Approximately 4.5% of patients who undergo LSG need revisional surgery for a dilated sleeve.Methods This randomized controlled trial compared the outcomes between banded (BLSG) and non-banded re-LSG (NBLSG) after weight regain. Percentage excess body weight loss (%EWL), percentage total weight loss (%TWL), associated medical problems, gastric volume measurement, and endoscopy were measured preoperatively and 1 and 2 years postoperatively.Results Both groups (25 patients each) achieved similar % EWL and %TWL at six months, one year, and two years postoperatively (%EWL 46.9 vs. 43.6, 83.7 vs. 86.3, and 85.7 vs. 83.9) (p= > 0.151) (%TWL 23.9 vs. 21.8, 43.1 vs.43.3, 44.2 vs. 42.2) (p=>0.342), respectively. However, the body mass index was significantly lower with BLSG (24.9 vs. NBLSG, 26.9). Both groups showed a significant reduction in stomach volume after two years (BLSG -248.4 mL vs. NBLSG -215.8 mL). Food tolerance (FT) scores were significantly reduced in both groups, whereby BSLG had significantly lower FT with an average of -1.1 point. No significant differences were observed regarding improvement of the associated medical problems after the first and two years after revisional LSG or the postoperative complications between both groups.Conclusion Laparoscopic re-LSG is feasible and safe with satisfactory outcomes in patients with weight regain after LSG who have gastric dilatation without reflux esophagitis. Both groups had comparable significant weight loss effects and improvement of associated medical problems. The BLSG tends to have a more stable weight loss after two years with a significantly lower BMI, lower stomach volume, and less weight regain. Food tolerance decreased in both groups but reduced more in the BLSG group. After a 2-year follow-up, we may regard both procedures are safe, with no significant differences in the occurrence of complications and nutritional deficits. Show less

Show morePurpose: Patients with prior bariatric surgery (BS) are at risk to develop alcohol use disorder (AUD) and alcohol-related liver disease (ALD). Severe alcoholic hepatitis (sAH) is one of the most severe manifestations of ALD with a 28-day mortality of 20-50%. The impact of prior BS on patients presenting with sAH was assessed. Methods: From 01/2008 to 04/2021, consecutive patients admitted to a tertiary referral center with biopsy-proven sAH were included in a database. Results: One hundred fifty-eight sAH patients of which 28 patients had a history of BS (BS group) were identified. Of this BS group, 24 patients underwent a Roux-en-Y gastric bypass (RYGB), 3 a biliopancreatic diversion, 1 an adjustable gastric band, and no patients a sleeve gastrectomy. The proportion of patients with BS increased threefold over time during the study period. Patients in the BS group were significantly younger at diagnosis of sAH (44.3 years vs 52.4 years), were more frequently female, and had a higher body mass index and a higher grade of steatosis on liver biopsy. The correlation between BS and a younger age at diagnosis remained significant in a multivariate regression analysis. There were no differences in disease severity between both groups. Furthermore, there were no differences in corticosteroid response, 28-day, 90-day, or 1-year survival. Conclusion: Prior BS is independently associated with a younger age of presentation with sAH, but is not independently associated with a different disease severity or outcome. These findings support the need for early detection of AUD in patients who underwent BS, in particular RYGB. Show less

Show moreIntroduction: Weight loss prior to bariatric-metabolic surgery (BMS) is recommended in most bariatric centers. However, there is limited high-quality evidence to support mandatory preoperative weight loss. In this study, we will evaluate whether weight gain prior to primary BMS is related to lower postoperative weight loss.Methods: A retrospective analysis of prospectively collected data was performed. Preoperative weight loss (weight loss from start of program to day of surgery), postoperative weight loss (weight loss from day of surgery to follow-up), and total weight loss (weight loss from start of program to follow-up) were calculated. Five groups were defined based on patients' preoperative weight change: preoperative weight loss of >5 kg (group I), 3-5 kg (group II), 1-3 kg (group III), preoperative stable weight (group IV), and preoperative weight gain >1 kg (group V). Linear mixed models were used to compare the postoperative weight loss between group V and the other four groups (I-IV).Results: A total of 1928 patients were included. Mean age was 44 years, 78.6% were female, and preoperative BMI was 43.7 kg/m2. Analysis showed significantly higher postoperative weight loss in group V, compared to all other groups at 12, 24, and 36 months follow-up. Up to three years follow-up, highest total weight loss was observed in group I.Conclusion: Weight gain before surgery should not be a reason to withhold a bariatric-metabolic operation. However, patients with higher preoperative weight loss have higher total weight loss. Therefore, preoperative weight loss should be encouraged prior to bariatric surgery. Show less

Show moreBackground Sleeve dilatation after laparoscopic sleeve gastrectomy (LSG) causes weight regain (WR). Banded sleeve gastrectomy (BSG) was proposed to prevent dilatation and reduce WR. Methods A retrospective cohort study on patients who underwent BSG and LSG and completed 4 years of follow-up from 2016 to 2021 was included. Body mass index (BMI), percentage of excess weight loss (%EWL), percentage of total weight loss (%TWL), and FT scores were calculated at 1, 2, 3, and 4 years. The sleeve volume was estimated at 6 months, 1 year, and 4 years. Multi-variate analysis was conducted to assess correlations between covariates. WR was calculated as weight gain > 10%, > 10 kg above the nadir, or BMI increase of >= 5 kg/m(2) above the nadir. Results This study included LSG 1279 patients and BSG 132 patients. Mean %EWL at 1 year was 83.87 +/- 17.25% in LSG vs. 85.71 +/- 7.92% in BSG and was 83.47 +/- 18.87% in LSG and 85.54 +/- 7.48% in BSG at 4 years. Both had significant weight loss over time (p. < 0.001) with no significant main effect of surgery (p.0.438). Mean sleeve volume at 6 months was 102.32 +/- 9.88 +/- 10.28 ml in LSG vs. 101.89 +/- 10.019 ml in BSG and at 4 years was 580.25 +/- 112.25 ml in LSG vs. 157.94 +/- 12.54 ml in BSG (p. < 0.001). WR occurred in 136 (10.6%) and 4 (3.1%) (p.0.002) in LSG and BSG patients, 90 (7%) vs. zero (0%) (p.0.002) and 31 (2.4%) vs. zero (0%) (p.0.07) using the > 10%, > 10 kg increase above the nadir and the >= 5 kg/m(2) BMI increases above the nadir formulas, respectively. Conclusion BSG had significantly lower sleeve volume, significantly lower WR, and significantly lower FT scores than LSG after 4 years from surgery; however, volume changes were not correlated with weight loss.

Show moreIntroduction Weight regain (WR) is described in approximately 30% of patient's post-bariatric surgery. It is related to the progression or recurrence of associated medical problems and decline in health-related quality of life. This study aimed to test the return of body composition and metabolic biomarkers to pre-operative levels when WR occurs. Methods In this cross-sectional study conducted in 2021, patients were randomly selected from the hospital's electronic databases between 2001 and 2020. Patient demographic data, comorbidities, body compositions, and metabolic biomarkers were collected. Three groups were defined: groups A (WR), B (weight loss), and C (control group; patients with obesity who had not yet undergone bariatric surgery). Results A total of 88 patients were enrolled in this study and matched with the control group. The body mass index in group A was 43.8 +/- 6.9 kg/m(2); group B was 28.6 +/- 4.2; group C was 43.9 +/- 7.1. Body muscle mass, body fat mass, and visceral fat significantly differed between groups A and B (p < 0.001) but not between groups A and C (p = 0.8). There was a significant difference in leptin, ghrelin, postprandial glucagon-like peptide-1, insulin, and fibroblast growth factor-21 (but not retinol-binding protein-4) between groups A and B. Most metabolic biomarkers in group A returned to the pre-operative values as in group C. Conclusion WR had a direct negative effect on body composition and metabolic biomarkers, whereby the values returned to pre-operative levels. Early detection of WR and possible additional therapy are necessary to prevent associated medical problems. Show less

Show moreBackground: To assess the prevalence, incidence, location, and behavior of chronic pre- and postoperative pain in bariatric surgery, and the use of analgesics.Methods: A cross-sectional e-survey was conducted on 3928 post-bariatric patients and four-time points for pain assessment were evaluated: preoperative, on the ward, day 1 at home postoperatively, and present time (at the time of the e-survey). A numerical rating scale (NRS) was used to assess the level of pain (0 to 10). The general incidence of chronic pain was calculated, as also, subgroups were defined as group A (pre and postoperative chronic pain), B (preoperative pain, and no longer postoperative), and C (preoperative painless, postoperative chronic pain). Besides the pain intensity, location of pain, and the use of analgesics were investigated. Results: A total of 3279 patients (83.9%) responded to the survey. Preoperative and postoperative chronic pain was found in 343 (10.5%) and 264 (8.1%) patients, respectively. In group A, chronic pain was present in 4.8% of the patients; in group B, it was present in 5.7%; and in group C in 3.3% of the patients. Furthermore, in 4.5% of patients pain was located in the abdomen, which was higher as compared to before surgery (+ 2.3%, p < 0.001). The ORs for present postoperative chronic pain were OR 1.45, 1.7, and 1.71 (p = 0.002, 0.003, 0.003) compared to respectively preoperative chronic pain, pain at the ward, and pain at day 1 after surgery. Among all participants, 4.6% consumed chronic analgesics. Of these, paracetamol was used most frequently (3.8%), followed by tramadol (1.3%) and oxycodone (0.5%). Conclusions: In this e-survey, chronic postoperative abdominal pain was prominent in patients after bariatric surgery. Of patients, 3.3% that were without preoperative chronic pain developed chronic pain after surgery. Opioid consumption in the queried population was relatively low. Show less

Show moreBackground: Lingering severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in gut tissue might be a source of infection during bariatric surgery. This study aimed to confirm the presence of SARS-CoV-2 nucleocapsid in gastric and gallbladder tissues removed during bariatric surgery in individuals previously infected with coronavirus disease 2019 (COVID-19) who had negative polymerase chain reaction results prior to the surgery.Methods: Gastric and gallbladder specimens from 80 patients who underwent bariatric surgery between November 2021 and May 2022 and had a history of COVID-19 infection with gastrointestinal symptoms were examined for the presence of lingering SARS-CoV-2 nucleocapsid proteins using immunohistochemistry.Results: Gastric specimens from 26 (32.5%) patients and 4 (100%) cholecystectomy specimens showed positive cytoplasmic staining for the anti-SARS-CoV-2 nucleocapsid protein in surface mucosal epithelial cells. The mean age was 37.8 +/- 10.3 years. The average body mass index was 44.2 +/- 7.0 kg/m(2); most of the patients were females (71.3%). The positive staining group was significantly younger than the negative staining group (p = 0.007). The full-dose vaccination rate was 58.8%, with a median of 91 days after the last vaccine dose. A positive serological anti-spike IgG response was observed in 99% of the patients. The median time between initial COVID-19 infection and surgery was 274 and 380 days in the positive and negative staining groups, respectively (p = 0.371).Conclusion: Gastric and gallbladder tissues can retain SARS-CoV-2 particles for a long time after COVID-19 infection, handling stomach specimens from patients during an operation must be done with care, as we usually do, but now with the knowledge that in 1/3 of patients they can be present. Performing LSG on post-COVID patients did not seem to increase perioperative morbidity. Show less

Show moreIntroduction: Obesity is associated with metabolic syndrome (MBS), a cluster of components including central obesity, insulin resistance (IR), dyslipidemia, and hypertension. IR is the major risk factor in the development and progression of type 2 diabetes mellitus in obesity and MBS. Predicting preoperatively whether a patient with obesity would have improved or non-improved IR after bariatric surgery would improve treatment decisions. Methods: A prospective cohort study was conducted between August 2019 and September 2021. We identified pre- and postoperative metabolic biomarkers in patients who underwent laparoscopic sleeve gastrectomy. Patients were divided into two groups: group A (IR < 2.5), with improved IR, and group B (IR >= 2.5), with non-improved IR. A prediction model and receiver operating characteristics (ROC) were used to determine the effect of metabolic biomarkers on IR. Results: Seventy patients with obesity and MBS were enrolled. At 12-month postoperative a significant improvement in lipid profile, fasting blood glucose, and hormonal biomarkers and a significant reduction in the BMI in all patients (p = 0.008) were visible. HOMA-IR significantly decreased in 57.14% of the patients postoperatively. Significant effects on the change in HOMA-IR >= 2.5 were the variables; preoperative BMI, leptin, ghrelin, leptin/ghrelin ratio (LGr), insulin, and triglyceride with an OR of 1.6,1.82, 1.33, 1.69, 1.77, and 1.82, respectively (p = 0.009 towards p = 0.041). Leptin had the best predictive cutoff value on ROC (86% sensitivity and 92% specificity), whereas ghrelin had the lowest (70% sensitivity and 73% specificity). Conclusion: Preoperative BMI, leptin, ghrelin, LGr, and increased triglycerides have a predictive value on higher postoperative, non-improved patients with HOMA-IR (>= 2.5). Therefore, assessing metabolic biomarkers can help decide on treatment/extra therapy and outcome before surgery. Show less

Show morePurpose: Hospitals performing a certain bariatric procedure in high volumes may have better outcomes. However, they could also have worse outcomes for some patients who are better off receiving another procedure. This study evaluates the effect of hospital preference for a specific type of bariatric procedure on their overall weight loss results. Methods: All hospitals performing bariatric surgery were included from the nationwide Dutch Audit for Treatment of Obesity. For each hospital, the expected (E) numbers of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB) were calculated given their patient-mix. These were compared with the observed (O) numbers as the O/E ratio in a funnel plot. The 95% control intervals were used to identify outlier hospitals performing a certain procedure significantly more often than expected given their patient-mix (defined as hospital preference for that procedure). Similarly, funnel plots were created for the outcome of patients achieving >= 25% total weight loss (TWL) after 2 years, which was linked to each hospital's preference. Results: A total of 34,558 patients were included, with 23,154 patients completing a 2-year follow-up, of whom 79.6% achieved >= 25%TWL. Nine hospitals had a preference for RYGB (range O/E ratio [1.09-1.53]), with 1 having significantly more patients achieving >= 25%TWL (O/E ratio [1.06]). Of 6 hospitals with a preference for SG (range O/E ratio [1.10-2.71]), one hospital had significantly fewer patients achieving >= 25%TWL (O/E ratio [0.90]), and from two hospitals with a preference for OAGB (range O/E ratio [4.0-6.0]), one had significantly more patients achieving >= 25%TWL (O/E ratio [1.07]). One hospital had no preference for any procedure but did have significantly more patients achieving >= 25%TWL (O/E ratio [1.10]). Conclusion: Hospital preference is not consistently associated with better overall weight loss results. This suggests that even though experience with a procedure may be slightly less in hospitals not having a preference, it is still sufficient to achieve similar weight loss outcomes when surgery is provided in centralized high-volume bariatric institutions.

Show moreBackground High rates of revision surgery have been reported for laparoscopic sleeve gastrectomy (LSG), with weight regain (WR) as the most frequently reported cause. Roux-en-Y gastric bypass (RYGB) is the most commonly performed revision procedure, whereas one-anastomosis gastric bypass (OAGB) is a less popular approach.Methods A single-blinded randomized controlled trial was conducted. One hundred seventy-six patients were enrolled and randomized. After loss to follow-up, 80 patients for RYGB and 80 patients for OAGB were analyzed, with a 2-year follow-up. Patients with grade B or higher gastroesophageal reflux disease (GERD) were excluded. Early and late postoperative complications were recorded. Body mass index (BMI), percentage of excess BMI loss (%EBMIL), nutritional laboratory test results, and the resolution of associated medical problems were assessed after revision surgery.Results After 2 years, both groups achieved significantly lower BMI than their post-LSG nadir BMI (p < 0.001). The %EBMIL changes showed significantly faster weight loss in the OAGB group than in the RYGB at the 6-month follow-up (mean difference: 8.5%, 95% confidence interval [CI]: 0.2 to 16.9%). However, at 1-year and 2-year follow-ups, the differences were statistically insignificant (p > 0.05). Early and late complications were similar between two groups. Both groups showed improvement or resolution of associated medical problems, with no statistically significant differences after 2 years (p = 1.00).Conclusion Both revisional RYGB and OAGB have comparable significant weight loss effects when performed for WR after LSG. After a 2-year follow-up, both procedures were safe, with no significant differences in the occurrence of complications and nutritional deficits. Show less

Show moreIntroduction: Vertical banded gastroplasty (VBG) is associated with high weight regain; Roux-en-Y gastric bypass (RYGB) is used as a revision procedure in patients with VBG experiencing weight regain. This study compared the 5-year follow-up outcomes of primary (PRYGB) and revision RYGB after VBG (RRYGB). Methods: Patients who underwent PRYGB or RRYGB after VBG from 2008 to 2016 were enrolled. Data on weight regain, weight loss (WL), food tolerance (FT), early and late complications, and resolution or improvement in associated medical conditions were analyzed.Results: PRYGB and RRYGB groups had 558 and 156 patients, respectively, after exclusion of the lost to follow-up patients. PRYGB group showed significantly lower mean body mass index (over the entire follow-up period), early complications, reintervention rates for late complications, and overall reintervention rates than that of the RRYGB group. On the other hand, FT scores, odds of late complications, and improvements (in the fifth year) in associated medical conditions were comparable between the two groups. Conclusion: RRYGB in patients with VBG who regained weight showed comparable safety and resolution of associated diseases to that of PRYGB over the 5-year follow-up period. The WL in the RRYGB group was acceptable despite being less than that of the PRYGB group. FT was better after RRYGB than that of PRYGB in the first year; however, both were comparable at the fifth year follow-up. Patients with VBG undergoing RYGB should receive attentive treatment and evaluation of associated factors. Show less

Grading of recommendations, assessment, development, and evaluations (GRADE), emphasizing the level of evidence (LoE) of both the guidelines, was performed. An overview of methodology was also performed, considering the following questions: how can research be improved, what can be done in the future using data, and how to collaborate more? Both guidelines did not explain how the LoE conclusions were derived regarding the risk of bias. There is also potential for forming a global consortium that deals with bariatric research, which can serve as a repository for all relevant data. Ensuring that this data is FAIR (findability, accessibility, interoperability, reusability) compliant and using this data to formulate future guidelines will benefit clinicians and patients alike.

Show morePurpose: To assess the effect of dialectical behavior therapy (DBT) on emotional and mindless eating and, consequently, body mass index (BMI) loss, in patients who have undergone bariatric surgery. Materials and Methods: A prospective exploratory cohort study was conducted with two groups of patients who had undergone bariatric surgery: the DBT group received DBT group skills training sessions, while the control group received no intervention. Outcome measurements included BMI and scores of the Emotional Eating Scale (EES) and Mindful Eating Questionnaire (MEQ). Results: The study included 36 women: 18 in each group. In the DBT group, the interval from surgery was 11.17 +/- 7.12 months, and in the control group 10.89 +/- 5.74. Laparoscopic sleeve gastrectomy was done in 88.9% and 83.3% of patients in the DBT and control groups respectively. The rest underwent Roux-en-Y gastric bypass. The DBT group showed significant changes in overall and subscale scores of the EES and MEQ and BMI in kg/m(2) after 6 months of follow-up. BMI in kg/m(2) changed from mean +/- SD 35.45 +/- 6.17 to 28.47 +/- 4.28 in the DBT group, in control 35.88 +/- 5.07 to 31.56 +/- 3.71. The excess weight loss percentage (EWL%) in the DBT was mean +/- SD 75.3 +/- 17.9 and in the control was 63.6 +/- 14.5. In the DBT group, the EES score and MEQ score changed from mean +/- SD 45.06 +/- 20.19 to 20.50 +/- 13.40 and 11.52 +/- 2.02 to 15.87 +/- 1.92, respectively. The control group showed no significant change in scores. Conclusions: DBT skills training can reduce emotional eating, increase mindful eating, and facilitate weight loss after bariatric surgery.

Show moreIntroduction Pooling population-based data from all national bariatric registries may provide international real-world evidence for outcomes that will help establish a universal standard of care, provided that the same variables and definitions are used. Therefore, this study aims to assess the concordance of variables across national registries to identify which outcomes can be used for international collaborations. Methods All 18 countries with a national bariatric registry who contributed to The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) Global Registry report 2019 were requested to share their data dictionary by email. The primary outcome was the percentage of perfect agreement for variables by domain: patient, prior bariatric history, screening, operation, complication, and follow-up. Perfect agreement was defined as 100% concordance, meaning that the variable was registered with the same definition across all registries. Secondary outcomes were defined as variables having "substantial agreement" (75-99.9%) and "moderate agreement" (50-74.9%) across registries. Results Eleven registries responded and had a total of 2585 recorded variables that were grouped into 250 variables measuring the same concept. A total of 25 (10%) variables have a perfect agreement across all domains: 3 (18.75%) for the patient domain, 0 (0.0%) for prior bariatric history, 5 (8.2%) for screening, 6 (11.8%) for operation, 5 (8.8%) for complications, and 6 (11.8%) for follow-up. Furthermore, 28 (11.2%) variables have substantial agreement and 59 (23.6%) variables have moderate agreement across registries. Conclusion There is limited uniform agreement in variables across national bariatric registries. Further alignment and uniformity in collected variables are required to enable future international collaborations and comparison. Show less
