Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) is the preferred method to achieve significant weight loss in patients with Obesity Class V (BMI > 60 kg/m2). However, there is no consensus regarding the best procedure(s) for this population. Additionally, these patients will likely have a higher risk of complications and mortality. The aim of this study was to achieve a consensus among a global panel of expert bariatric surgeons using a modified Delphi methodology. METHODS A total of 36 recognized opinion-makers and highly experienced metabolic and bariatric surgeons participated in the present Delphi consensus. 81 statements on preoperative management, selection of the procedure, perioperative management, weight loss parameters, follow-up, and metabolic outcomes were voted on in two rounds. A consensus was considered reached when an agreement of ≥ 70% of experts' votes was achieved. RESULTS A total of 54 out of 81 statements reached consensus. Remarkably, more than 90% of the experts agreed that patients should be notified of the greater risk of complications, the possibility of modifications to the surgical procedure, and the early start of chemical thromboprophylaxis. Regarding the choice of the procedure, SADI-S, RYGB, and OAGB were the top 3 preferred operations. However, no consensus was reached on the limb length in these operations. CONCLUSION This study represents the first attempt to reach consensus on the choice of procedures as well as perioperative management in patients with obesity class V. Although overall consensus was reached in different areas, more research is needed to better serve this high-risk population.

Abstract
INTRODUCTION The Lancet Commission on Global Surgery seeks to improve surgical care outcomes and equity for the world population through 6 indicators outlined in its 2030 Global Surgery Report. Our study aimed to estimate the percentage of the Mexican population with access to surgical care within the 2-hour distance range (indicator 1), the surgical workforce density (indicator 2), and the number of surgical procedures performed per 100,000 inhabitants (indicator 3) during the year 2020. Knowing these indicators can help to design and implement policies to increase surgical care access coverage and equity in our country. METHODS Data related to population distribution, local referral hospitals, and surgical volume were obtained from the 2020 Mexican National Census. Information relating to hospital characteristics and surgical specialists was collected from the Secretariat of Health's public records. We calculated travel time between health care facilities and municipalities using the TrueWay Matrix API and R Studio. RESULTS Taking into consideration the health care system affiliation, the proportion of the Mexican population with timely access to essential surgery was 81.7%, with 29.3 specialists per 100,000 inhabitants and 726.9 annual procedures performed per 100,000 inhabitants. We identified clusters of municipalities where a low proportion of the population has timely access to essential surgery. CONCLUSION These findings illustrate that changes in Mexican policy are required to facilitate more equitable and timely access to essential surgical care among the population.

Abstract
BACKGROUND Intraoperative parathyroid hormones have been used to establish operative success in patients with primary hyperparathyroidism. This study's aim was to assess the impact of estimated glomerular filtration rate and serum creatinine levels on the fulfillment of >50% drop and normalization of intraoperative parathyroid hormone levels. METHODS Patients successfully treated for primary hyperparathyroidism were analyzed. The samples for parathyroid hormone were collected at baseline, 5-, 10-, and 30-minutes postexcision. The patients were classified as follows: (1) estimated glomerular filtration rate >60 mL/min, (2) estimated glomerular filtration rate <60 mL/min and serum creatinine levels <1.2 mg/dL, and (3) estimated glomerular filtration rate <60 mL/min and serum creatinine levels >1.2 mg/dL. Comparative analysis of patients achieving the >50% parathyroid hormone drop criterion and normalization of intraoperative parathyroid hormone was performed. RESULTS One hundred-fourteen patients were distributed as follows: 88 patients (77.2%), 14 (12.3%), and 12 (10.5%) for groups 1, 2 and 3, respectively. No difference between groups in the proportion of patients fulfilling the >50% parathyroid hormone drop criterion was found. An abnormally elevated intraoperative parathyroid hormone level at 30-minute postexcision was observed in 0, 14.3, and 16.6% in groups 1, 2, and 3, respectively (P ≤ .0001). CONCLUSION In the study, >50% parathyroid hormone drop criterion was equally achieved despite normal or reduced estimated glomerular filtration rate. When serum creatinine levels increased >1.2 mg/dL and estimated glomerular filtration rate declined <60 mL/min, the likelihood of reaching normal intraoperative parathyroid hormone levels postexcision was significantly lower.

Abstract
BACKGROUND Sleeve gastrectomy (SG) is the most common bariatric procedure performed worldwide. It accounts for more than 50% of primary bariatric surgeries performed each year. Recent long-term data has shown an alarming trend of weight recidivism. Some authors have proposed the concurrent use of a non-adjustable gastric band to decrease long-term sleeve failure. OBJECTIVE To compare the outcomes (weight loss) and safety (rate of complication and presence of upper GI symptoms) between SG and BSG. METHODS A systematic search with no language or time restrictions was performed to identify relevant observational studies and randomized controlled trials (RCT) evaluating people with morbid obesity undergoing SG or SGB for weight loss. An inverse-of-the-variance meta-analysis was performed by random effects model. Heterogeneity was assessed using Cochrane X2 and I2 analysis. RESULTS A total of 7 observational studies and 3 RCT were included in the final analysis. There were 911 participants pooled from observational studies and 194 from RCT. BSG showed a significant higher excess of weight loss (% EWL). The difference among groups was clinically relevant after the third year where the weighted mean difference (SMD) was 16.8 (CI 95% 12.45, 21.15, p < 0.0001), while at 5 years, a SMD of 25.59 (16.31, 34.87, p < 0.0001) was noticed. No differences related to overall complications were noticed. Upper GI symptoms were up to three times more frequent in the BSG group (OR 3.26. CI 95% 1.96, 5.42, p < 0.0001). CONCLUSIONS According to the results, BSG is superior to SG in weight loss at 5 years but is associated with a higher incidence of upper GI symptoms. However, these conclusions are based mainly on data obtained from observational studies. Further RCT are needed to evaluate the effect and safety of BSG.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) has been proposed as a rescue technique for laparoscopic adjustable gastric banding (LAGB) poor responders. AIM We sought to analyze, complications, mortality, and medium-term weight loss results after LAGB conversion to OAGB. METHODS Data analysis of an international multicenter database. RESULTS One hundred eighty-nine LAGB-to-OAGB operations were retrospectively analyzed. Eighty-seven (46.0%) were converted in one stage. Patients operated on in two stages had a higher preoperative body mass index (BMI) (37.9 vs. 41.3 kg/m2, p = 0.0007) and were more likely to have encountered technical complications, such as slippage or erosions (36% vs. 78%, p < 0.0001). Postoperative complications occurred in 4.8% of the patients (4.6% and 4.9% in the one-stage and the two-stage group, respectively). Leak rate, bleeding episodes, and mortality were 2.6%, 0.5%, and 0.5%, respectively. The final BMI was 30.2 at a mean follow-up of 31.4 months. Follow-up at 1, 3, and 5 years was 100%, 88%, and 70%, respectively. CONCLUSION Conversion from LAGB to OAGB is safe and effective. The one-stage approach appears to be the preferred option in non-complicate cases, while the two-step approach is mostly done for more complicated cases.

Abstract
BACKGROUND There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates. METHODS We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020. RESULTS Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country. CONCLUSIONS BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak.

Abstract
BACKGROUND Adrenocortical carcinoma is a rare malignant tumor with a poor prognosis. Discernment of adrenocortical carcinoma in an adrenal mass through imaging studies is paramount for early surgical treatment. Recently, necrosis has been proposed as a single morphological parameter for adrenocortical carcinoma diagnosis. The aim of this study was to analyze the measures of diagnostic efficiency of necrosis and the different computed tomography-scan features related to adrenocortical carcinoma diagnosis. METHODS We conducted a case-control study of patients surgically treated for an adrenal mass with histopathological report consistent with adrenocortical carcinoma (cases) and adrenocortical adenoma (control patients) between 1987 and 2019. Radiological features on computed tomography scan were collected. Bivariate and multivariate statistical analyses were performed for the different imaging features. The measures of diagnostic efficiency for each feature were calculated. Concordance analysis between image-detected and histopathological-identified necrosis was performed. RESULTS Eighteen adrenocortical carcinoma and 41 adrenocortical adenomas were included. Differences between adrenocortical carcinoma and adrenocortical adenoma were found regarding heterogeneity (odds ratio 4.53, 95% confidence interval 2.3-8.9; P < .0001), tumor size ≥4 cm (odds ratio 3.5, 95% confidence interval 2.05-6.14; P < .0001), and attenuation index ≥10 Hounsfield units (odds ratio 1.9, 95% confidence interval 1.3-2.6; P = .001). Necrosis was the most important imaging feature significantly associated with adrenocortical carcinoma (odds ratio 35, 95% confidence interval 5.1-241.6; P < .0001), present in all adrenocortical carcinoma cases. After measures of diagnostic efficiency calculation, necrosis had the highest diagnostic accuracy (98%). Cohen's kappa for concordance between image-detected and histopathological-identified necrosis was 90.4% (P < .0001). CONCLUSION Computed tomography scan-detected necrosis is a reliable radiological feature to discern adrenocortical carcinoma from adrenocortical adenomas.

Abstract
Bariatric surgery is extremely safe and effective, but several factors need to be addressed to obtain such results. Patient selection, type of training, accreditation, type of practice, and surgical trends and technique are involved in this process. Local and global standardization are ill-advised, especially in countries with high obesity prevalence, and where the bariatric practice is fast growing.An online survey with 22 questions was sent to bariatric surgeons in Mexico. Only participants with the active practice were included, and the aim was to obtain for the first time insight in bariatric surgery training, characteristics of current practice and surgical trends.Complete responses from 114 surgeons were obtained. Most were male, under 50 years-old, ≤ 10 years of experience, and practice in low-volume hospitals. Less than half had a 12-month formal training. Gastric bypass and sleeve gastrectomy were the most common procedures. Practice trends like leak tests, use of drains, preoperative weight loss, routine endoscopy, and pharmacological tromboprofilaxis are common. In surgical technique, the gastric bypass and sleeve gastrectomy confection was more homogenic when compared to the one-anastomosis gastric bypass.Complete responses from 114 surgeons were obtained.

In surgical technique, the gastric bypass and sleeve gastrectomy confection was more homogenic when compared to the one-anastomosis gastric bypass. An important number of bariatric surgeons in Mexico are young, male, and with < 10 years of practice. The most common techniques performed are gastric bypass and sleeve gastrectomy. Several practices and technique trends are similar to global consensus. Fellowship programs and Board Certification in bariatric surgery are major advances in our country, thus standardization and high-quality practice can be achieved.

Abstract
AIM Severe hypocalcaemia following parathyroidectomy for secondary or tertiary hyperparathyroidism (SHPT/THPT) is scarcely studied. We aimed to describe and identify risk factors for early and persistent hypocalcaemia after parathyroidectomy. METHODS Retrospective pair-matched cohort study. We assessed 87 dialysis patients with SHPT (n = 73) or THPT (n = 14) paired with 146 subjects with primary hyperparathyroidism (PHPT) who underwent parathyroidectomy and were followed for 12 months. Early severe hypocalcaemia was defined as a free Ca ≤0.8 mmol/L [3.2 mg/dl] or corrected Ca ≤1.87 mmol/L [7.5 mg/dl] within 48 h. After parathyroidectomy and persistent hypocalcaemia, as an elemental Ca intake >3.0 g/day to achieve corrected Ca >2 mmol/L [8.0 mg/dl]. RESULTS Early severe hypocalcaemia occurred in 77% (67/87) versus 6.8% (10/146) of subjects with SHPT/THPT and PHPT, respectively (p < .001). In SHPT/THPT cases, persistent hypocalcaemia occurred in 77% (49/64) and 64% (35/54) after 6 and 12 months of parathyroidectomy, respectively. In PHPT cases, persistent hypocalcaemia occurred in 6.8% (10/146) after 4-12 months of parathyroidectomy. Preoperative serum alkaline phosphatase (ALP) was the only risk factor associated to early severe hypocalcaemia (OR 7.3, 95% C.I. 1.7-10.9, p = .006) and persistent hypocalcaemia (OR 7.1, 95% C.I: 2.1-14.2, p = .011). Subjects with persistently low intact parathormone (iPTH) (<5.3 pmol/L [50 ng/ml]), suggestive of adynamic bone disease) showed higher Ca increases and less oral calcium requirements compared to those who progressively increased iPTH after parathyroidectomy. CONCLUSION Early and persistent hypocalcaemia after parathyroidectomy in severe HPT were a common event associated directly to preoperative ALP levels. Subjects with persistently low postoperative iPTH normalized serum Ca more frequently after 1 year of follow up.

Abstract
Background Outcomes after adrenalectomy in patients with primary aldosteronism (PA) are variable. The aldosteronoma resolution score (ARS) uses preoperative variables to calculate a score that identifies those patients that are more likely to have resolution of hypertension after adrenalectomy. We aim to determine the efficacy of adrenalectomy and whether the ARS accurately predicts clinical success in a Black and Hispanic population. Methods We reviewed patients who underwent adrenalectomy for PA from 2004 to 2018 at two academic centers treating primarily Hispanic and Black patients. Postoperative outcomes were evaluated based on the primary aldosteronism surgical outcome consensus criterion. Retrospectively, the accuracy of ARS was determined by a receiver operating characteristic curve and the area under the curve (AUC). Results Forty-three Hispanic and 10 Black patients underwent adrenalectomy for PA. Twenty-two patients (41.5%) had complete clinical success. Variables associated with complete clinical success in the univariate analysis were female gender (p = 0.026), younger age (p = 0.001), lower preoperative aldosterone (p = 0.035), lower preoperative systolic blood pressure (p = 0.001), fewer number of preoperative antihypertensive medications (p = 0.007) and a higher ARS (p = 0.003). On multivariate analysis, only fewer number of preoperative antihypertensive medications was independently associated with complete clinical success (p = 0.026). The AUC of the ARS was 0.746. Conclusion The rate of clinical success from adrenalectomy is good for Hispanic and Black patients with PA. Our analysis shows that the ARS is an accurate test of clinical success in Hispanic and Black patients. The ARS may be utilized preoperatively to frame expectations after adrenalectomy in these populations.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) has become one of the most commonly performed gastric bypass procedures in some countries. OBJECTIVES To assess how surgeons viewed the OAGB, perceptions, indications, techniques, and outcomes, as well as the incidence of short- and long-term complications and how they were managed worldwide. METHODS A questionnaire was sent to all IFSO members in all 5 chapters to study the pattern of practice and outcomes of OAGB. RESULTS Seven hundred and forty-two surgeons responded. The most commonly performed procedures were sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and OAGB. Preoperatively, 70% of the surgeons performed endoscopy routinely. In regards to weight loss, 83% (570 surgeons) responded that OAGB produces better weight loss than SG, and 49% (342 surgeons) responded that OAGB produces better weight loss than RYGB. The most common length of the biliopancreatic limb (BPL) utilized was 200 cm. Sixty-seven percent of surgeons did not measure the total length of the small bowel. In patients with reflux disease and history of smoking, 53% and 22% of surgeons respectively still offered OAGB as a treatment option. Postoperatively, leak was documented in 963 patients, and it was the leading cause for mortality. Leak management was conservative in 35%. Conversion to RYGB was performed in 31%. In 16% the anastomosis was reinforced, 6% of the patients were reversed, and other procedures were performed in 12%. Revision of OAGB for malnutrition/steatorrhea or severe bile reflux was reported at least once by 37% and 45% of surgeons, respectively (200 cm was the most commonly encountered biliopancreatic limb BPL in those revised for malnutrition). Most common strategy for revision was conversion to RYGB (43%), reversal to normal anatomy (32%), shortening of the BPL (20%), and conversion to SG (5%). Nevertheless, 5 out of 98 mortalities (5%) were due to liver failure/malnutrition. CONCLUSION There are infrequent but potentially severe specific complications including malnutrition, liver failure, and bile reflux that may require surgical correction after OAGB.

Abstract
BACKGROUND Cardiovascular disease (CVD) is highly prevalent in obese patients and is the leading cause of death. High levels of plasma low-density lipoprotein cholesterol (LDL-C) are associated with higher coronary artery disease (CAD) risk. The aim of the study was to assess the impact of the Roux-en-Y gastric bypass on the achievement of the currently proposed cardiovascular prevention goals after 1 year. PATIENTS AND METHODS We performed a retrospective analysis from a prospectively built database of patients who underwent a primary Roux-en-Y gastric bypass (RYGB) from 2004 to 2018. Patients with intermediate, high, or very high risk for CVD according to the 2018 AHA/ACC or the 2019 ESC/EAS guidelines were selected. An analysis of clinical and biochemical variables in 1 year was performed. Logistic multivariate regressions were made to assess the impact of preoperative and weight loss parameters in the achievement of LDL-C goals. RESULTS From 1039 patients, 70 met the selection criteria and were included in the analysis of the 2018 AHA/ACC guidelines, and 75 in the 2019 ESC/EAS guidelines. Mean decrease in LDL-C levels was 21.1 ± 40.2 mg/dL 1 year after surgery, and 29/34 patients were off medications. The percentage of patients achieving LDL-C goals according to the 2018 AHA/ACC guidelines was 27.1%, whereas according to the 2019 ESC/EAS guidelines, the percentages was 9.3%. The %TWL was associated with achieving LDL-C goals according to the 2018 AHA/ACC at 1 year. CONCLUSIONS RYGB induces a significant weight loss and an improvement in LDL-C levels 1 year after surgery. The number of patients that reached the goals varies according to the guidelines used and ranged from 9.3 to 27.1%.

Abstract
The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has been playing an integral role in educating both the metabolic surgical and the medical community at large about the importance of surgical and/or endoscopic interventions in treating adiposity-based chronic diseases. The occurrence of chronic conditions following bariatric/metabolic surgery (BMS), such as gastro-oesophageal reflux disease (GERD) and columnar (intestinal) epithelial metaplasia of the distal oesophagus (also known as Barrett's oesophagus (BE)), has long been discussed in the metabolic surgical and medical community. Equally, the risk of neoplastic progression of Barrett's oesophagus to oesophageal adenocarcinoma (EAC) and the resulting requirement for surgery are the source of some concern for many involved in the care of these patients, as the surgical alteration of the gastrointestinal tract may lead to impaired reconstructive options. As such, there is a requirement for guidance of the community.The IFSO commissioned a task force to elucidate three aspects of the presenting problem: First, to determine what the estimated incidence of Barrett's oesophagus is in patients presenting for BMS; second, to determine the frequency at which Barrett's oesophagus may develop following BMS (with a particular focus on the laparoscopic sleeve gastrectomy (LSG)); and third, to determine if regression of Barrett's oesophagus may occur following BMS given the close relationship of obesity and the development of BE/EAC. Based on these findings, a position statement regarding the management of this pathology in the context of BMS was developed. The following position statement is issued by the IFSO Barrett's Oesophagus task force andapproved by the IFSO Scientific Committee and Executive Board. This statement is based on current clinical knowledge, expert opinion and published peer-reviewed scientific evidence. It will be reviewed regularly.

Abstract
INTRODUCTION Sleeve gastrectomy (SG) is the commonest bariatric procedure worldwide. Yet there is significant variation in practice concerning its various aspects. This paper report results from the first modified Delphi consensus-building exercise on SG. METHODS We established a committee of 54 globally recognized opinion makers in this field. The committee agreed to vote on several statements concerning SG. An agreement or disagreement amongst ≥ 70.0% experts was construed as a consensus. RESULTS The committee achieved a consensus of agreement (n = 71) or disagreement (n = 7) for 78 out of 97 proposed statements after two rounds of voting. The committee agreed with 96.3% consensus that the characterization of SG as a purely restrictive procedure was inaccurate and there was 88.7% consensus that SG was not a suitable standalone, primary, surgical weight loss option for patients with Barrett's esophagus (BE) without dysplasia. There was an overwhelming consensus of 92.5% that the sleeve should be fashioned over an orogastric tube of 36-40 Fr and a 90.7% consensus that surgeons should stay at least 1 cm away from the angle of His. Remarkably, the committee agreed with 81.1% consensus that SG patients should undergo a screening endoscopy every 5 years after surgery to screen for BE. CONCLUSION A multinational team of experts achieved consensus on several aspects of SG. The findings of this exercise should help improve the outcomes of SG, the commonest bariatric procedure worldwide, and guide future research on this topic.

Abstract
PreambleThe International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has played an integral role in educating both the metabolic surgical and the medical communities at large about the role of innovative and new surgical and or endoscopic interventions in treating adiposity-based chronic diseases. The single anastomosis duodenal-ileal bypass with sleeve gastrectomy/one anastomosis duodenal switch (SADI-S/OADS) is a relatively new procedure that has been proposed as an alternative to the conventional duodenal switch (DS) procedure. The IFSO published a position paper on SADI-S/OADS in 2018 with which concluded that this procedure was likely to be a safe and efficacious treatment for adiposity and its related diseases. However, it noted that there was insufficient long-term data and minimal high-level evidence available. The position statement called for patients to be enrolled in long-term multidisciplinary care encouraged the registration of patients in national registries, and called for more randomized controlled trials (RCT) (Obes Surg 28:1207-16, 2018) involving the procedure. The following position statement is an update of the previous position statement. It is issued by the IFSO SADI-S/OADS task force and has been reviewed and approved by both the IFSO Scientific Committee and Executive Board. This statement is based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence. It will be reviewed again in 2 years.

Abstract
BACKGROUND Obesity is a common disease in the elderly population, and bariatric surgery is the most effective intervention to achieve significant and sustainable weight loss. Many bariatric programs have established an arbitrary cutoff at the age of 60 to 65 years. The aim of this study was to evaluate the safety and short-term outcomes of Roux-en-Y gastric bypass (RYGB) in patients older than 60 years. PATIENTS AND METHODS We conducted a retrospective cohort study of patients who underwent RYGB from 2004 to 2019 in a single center. Logistic and linear multivariate regressions were made to compare complications and short-term outcomes between patients aged > 60 years and < 60 years. The statistical significance was set at p ≤ 0.05. RESULTS From 849 patients who underwent a primary RYGB, 57 were > 60 years of age. Overall, early and late complications were similar in both groups, except for unexpected intensive care unit (ICU) admission which was more frequent in the > 60 years group. Excess body weight loss (%EWL) and percentage total weight loss (%TWL) at 1 year in patients > 60 years old were 76.6 ± 21.8% and 30.73 ± 6.8%, respectively. Figures for the same parameters in the control group were 81.7 ± 19.9% (p = 0.09) and 34.3 ± 7.2 (p = 0.001), respectively. CONCLUSIONS In our experience, an age > 60 is not related to higher rates of overall early and late complications after RYGB. Comorbidity remission rates are similar to those in younger patients. Elderly patients had lower total weight loss at 1 year, but the %EWL was similar in both groups.

Abstract
The purpose of this study was to achieve consensus amongst a global panel of expert bariatric surgeons on various aspects of resuming Bariatric and Metabolic Surgery (BMS) during the Coronavirus Disease-2019 (COVID-19) pandemic. A modified Delphi consensus-building protocol was used to build consensus amongst 44 globally recognised bariatric surgeons. The experts were asked to either agree or disagree with 111 statements they collectively proposed over two separate rounds. An agreement amongst ≥ 70.0% of experts was construed as consensus as per the predetermined methodology. We present here 38 of our key recommendations. This first global consensus statement on the resumption of BMS can provide a framework for multidisciplinary BMS teams planning to resume local services as well as guide future research in this area.

Abstract
Background: The incidence of micropapillary thyroid carcinoma (mPTC) has increased in the last decade. Active surveillance (AS) has been proposed as an alternative management for low-risk mPTC based on preoperative Kuma criteria. Controversy still exists on how to appropriately manage this group of patients, as some low-risk mPTC may harbor some postoperative features associated with disease recurrence as described in the 2015 American Thyroid Association (ATA) guidelines. Methods: We retrospectively reviewed 108 patients with histopathologic diagnosis of mPTC after surgery at a third level hospital in Mexico City from 2000 to 2018. Demographic and clinicopathologic data were analyzed as predictors for disease recurrence and/or metastatic disease (lymph node or distant). Comparison between group stratification based on preoperative Kuma criteria and postoperative 2015 ATA guidelines risk criteria for disease recurrence was performed. Measures of diagnostic accuracy were obtained for preoperative risk features according to the Kuma criteria. Results: Of 108 patients, 79 (73%) were classified as preoperative high-risk mPTC and 29 (27%) as low risk based on the Kuma criteria. Of these 79 high-risk patients, 38 (48%) were reclassified as low risk for disease recurrence, 12 (15%) as intermediate risk, and 29 (37%) remained as high risk based on the 2015 ATA risk criteria. Of the 29 preoperative low-risk patients, 19 (65.5%) remained as postoperative low risk for disease recurrence, 2 (7%) as intermediate risk, and 8 (27.5%) as high risk. Higher accuracy of preoperative risk features was obtained for lymph node and distant metastases, 84.2% and 97.2%, respectively. After multivariate analysis, age <40 years and microscopic extrathyroidal extension (ETE) were associated with higher risk for metastatic disease (lymph node or distant) in our cohort. Conclusions: Patients with mPTC under 40 years old and microscopic ETE are more prone to develop metastatic disease (lymph node or distant). One-third of our patients stratified as low-risk mPTC according to the Kuma criteria for AS had histopathologic features associated with a more aggressive clinical behavior or structural recurrence. In addition, lymph node and distant metastases are the preoperative risk features with the highest diagnostic accuracy for preoperative risk stratification.

Abstract
BACKGROUND Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is one of the most commonly performed bariatric procedures. Considering significant differences between populations around the world, surgical outcomes may vary widely. The aim of the study was to develop an educational patient-specific interactive application that may estimate the potential outcomes of LRYGB in the Mexican population. METHODS A database with 76 different variables from 1002 patients who underwent LRYGB at two Mexican Institutions between 1992 and 2014 and had a minimum of 6-month follow-up was analyzed. Descriptive and inferential statistics, as well as a multivariate regression analysis, were performed for the primary analysis. Results were based on four statistical models obtained from the cohort outcomes. A tool was designed to provide estimates of absolute weight loss (AWL) and resolution of four major comorbidities: type 2 diabetes (T2D), high blood pressure (HBP), hypercholesterolemia, and the obstructive syndrome of sleep apnea (OSAS). RESULTS There were 353 males (35.2%) and 649 females (64.8%) with a mean age of 41.9 ± 12.1 years and a mean preoperative BMI of 45.3 ± 7.9 kg/m2. Mean AWL at 2 years was 39.02 ± 12.7 kg. Mean accumulative percentage of resolution for T2D, HBP, and dyslipidemias at the same time period was 78%, 66.2%, and 84.7%, respectively. Based on these results, the educational tool was developed. CONCLUSIONS We were able to develop an interactive estimation application to provide a population-based guidance for potential outcomes of LRYGB. This might be useful not only for health professionals but also for patients interested in learning potential outcomes in specific circumstances.

Abstract
BACKGROUND Total thyroidectomy is the most common surgical procedure for the treatment of thyroid diseases. Postoperative hypocalcemia/hypoparathyroidism is the most frequent complication after total thyroidectomy. The aim of this study was to evaluate the rate of postoperative hypocalcemia and permanent hypoparathyroidism after total thyroidectomy in order to identify potential risk factors and to evaluate the impact of parathyroid autotransplantation. PATIENTS AND METHODS We performed a retrospective analysis of 1018 patients who underwent total thyroidectomy at our institution between 2000 and 2016. Medical records were reviewed to analyze patient features, clinical presentation, management and postoperative complications. Descriptive and inferential statistics were employed based on the natural scaling of each included variable. Statistical significance was set at p ≤ 0.05. RESULTS Mean ± SD age was 46.79 ± 15.9 years; 112 (11.7%) were males and 844 (88.3%) females. A total of 642 (67.2%) patients underwent surgery for malignant disease. The rate of postoperative hypocalcemia, transient, protracted and permanent hypoparathyroidism was 32.8%, 14.43%, 18.4% and 3.9%, respectively. Permanent hypoparathyroidism was significantly associated with the number of parathyroid glands remaining in situ (4 glands: 2.5%, 3 glands: 3.8%, 1-2 glands: 13.3%; p ˂ 0.0001) [OR for 1-2 glands in situ = 5.32, CI 95% 2.61-10.82]. Other risk factors related to permanent hypoparathyroidism were obesity (OR 3.56, CI 95% 1.79-7.07), concomitant level VI lymph node dissection (OR 3.04, CI 95% 1.46-6.37) and incidental parathyroidectomy without autotransplantation (OR 3.6, CI 95% 1.85-7.02). CONCLUSIONS Identification and in situ preservation of at least three parathyroid glands were associated with a lower rate of postoperative hypocalcemia (30.4%) and permanent postoperative hypoparathyroidism (2.79%).

Abstract
INTRODUCTION Recurrence of papillary thyroid carcinoma after initial treatment is challenging. Surgical reintervention is recommended, but cure after surgery in uncertain and surgical morbidity may be high. This study evaluates the effect of compartment-oriented lymph node dissection (LND) on clinical and biochemical cure rate as well as the related complications. PATIENTS AND METHODS All patients who underwent LND for recurrent papillary thyroid carcinoma between 2000 and 2015 were included. Demography, the extent of the initial surgery, usage of 131I, the pattern of recurrence, diagnosis, details of the surgical reintervention, histological findings, surgical morbidity, and clinical and biochemical outcomes were analyzed. RESULTS There were 11 (12.7%) males and 75 (87.2%) females with a mean age of 42.8 ± 14.6 years. Seventy-seven patients had undergone total thyroidectomy and in 67 (77.9%) some type of LN resection. In 76 (88.3%), 131I was administered after the initial surgery. We localized suspicious lymph nodes by US in all patients, and metastases were documented before surgery by FNA in 63. Seven (8.13%) patients underwent central LND, 63 (73.2%) lateral LND and 16 (18.6%) both, central and lateral LND. Major complications occurred in 6 patients (6.9%). Sixty-two (72.0%) patients received 131I after surgery. A second surgical re-exploration was performed in 30 (34.8%) patients, and 7 patients required 3 or more additional LND. In a mean follow-up of 59.4 ± 39 months, 51 (59.3%) patients are clinically, radiologically and biochemically free of disease. CONCLUSIONS In this series, compartment-oriented lymph node resection of recurrent papillary thyroid carcinoma leads to a final clinical and biochemical disease-free status of 59.3% with 6.9% of major complications.

Abstract
BACKGROUND To date, laparoscopic adjustable gastric banding remains the third most commonly performed surgical procedure for weight loss. Some patients fail to get acceptable outcomes and undergo revisional surgery at rates ranging from 7% to 60%. Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB), and sleeve gastrectomy (SG) are among the most common salvage options for failed laparoscopic adjustable gastric banding. OBJECTIVE To compare the outcomes of converting failed laparoscopic adjustable gastric banding to RYGB, OAGB, or SG. METHODS Data collected from 7 experienced bariatric centers around the world were retrospectively collected, reviewed, and analyzed. Final body mass index (BMI), change in BMI, percentage excess BMI loss, and major complications with particular attention to leaks, hemorrhage, and mortality were reported. RESULTS Of 1219 patients analyzed, 74% underwent RYGB, 16% underwent OAGB, and 10% underwent SG after banding failure. The mean age was 38 years (±10 yr), and 82% of patients were women. The mean follow-up was 33 months. The follow-up rate was 100%, 87%, and 52% at 1, 3, and 5 years, respectively. At the latest follow-up, percentage excess BMI loss >50% was achieved by 75% of RYGB, 85% of OAGB, and 67% of SG patients. Postoperative complications occurred in 13% of patients after RYGB, 5% after OAGB, and 15% after SG. CONCLUSION Our data show that it is possible to achieve or maintain significant weight loss with an acceptable complication rate with all 3 surgical options.

Abstract
Substernal goiter is defined as a thyroid growth beyond the thoracic inlet. Using the cross-section imaging CT system, it can be classified into three grades. The aim of the study was to validate the surgical approach and the occurrence of postoperative complications with substernal goiter extension in our patient population. From a total of 1145 patients who underwent thyroid surgery at our institution in a 15-year period, 60 patients with substernal goiter were included. Clinical features and demographics, degree of extension, surgical details, and complications were analyzed. Mean ± SD age of the patients was 58 ± 14.7 years and 88 per cent were females. According to the cross-section imaging CT system 61.7 per cent were grade I,23.3 per cent grade II, and 15 per cent grade III. Total thyroidectomy was performed in 78.3 per cent of the patients, subtotal thyroidectomy in 18.3 per cent, and lobectomy in 3.3 per cent. The cervical approach was sufficient to perform 96.7 per cent of the thyroidectomies, requiring partial sternotomy in only two patients with grade III substernal goiter. Patients with grade III substernal goiter had a higher risk for postoperative dysphonia (OR = 14.29, IC95% 1.14-178.9, P = 0.03), which occurred in three patients (two transient and one permanent). Transitory hypoparathyroidism was present in 20 patients (33.3%) and did not correlate with goiter extension. Most substernal goiters can be resected through a cervical approach, with relatively low morbidity. Postoperative dysphonia was directly related to the extension of the goiter. Few cases with grade III goiters require a partial sternotomy.

Abstract
AIM The aim of this study is to compare the differences in body composition in patients with obesity with successful weight loss (SWL) and unsuccessful (USWL) 1 year after Roux-en-Y gastric bypass (RYGB). METHODS We included 36 women and 22 men. After stratifying patients according with SWL (defined as ≥ 50% of excess weight loss), fat-free mass (FFM) and fat mass (FM) trajectories were analyzed in each group. RESULTS The %FM in SWL women (78%) was lower than USWL (36 vs. 44, p < 0.001). The %FM in SWL men (77%) was lower than USWL (27 vs. 38, p < 0.05). A lower %FM before surgery increased the probability of success (p < 0.05). CONCLUSIONS SWL patients have a lower %FM, and those with lower pre-surgical %FM are more likely to have SWL 1 year after RYGB.

Abstract
BACKGROUND Advanced bipolar and ultrasonic energy have demonstrated reduction of operating time and blood loss in thyroidectomy. However, these devices generate heat and thermal dispersion that may damage adjacent structures such as the recurrent laryngeal nerve (RLN). This study was designed to evaluate the safety profile of the Harmonic Focus+® (HF+) device through the evaluation of thermal injury to the RLN using different algorithms of distance and time with state of the art technology. METHODS 25 Vietnamese pigs underwent activation of HF+ in the proximity of their RLN. They were divided into 4 groups according to activation distance (3 mm, 2 mm, 1 mm and on the RLN). Time of activation, time between tones of the ultrasonic generator, changes in the electromyographic signal using continuous nerve neuromonitoring, vocal fold mobility assessed by direct laryngoscopy and histological thermal damaged were evaluated. RESULTS None of the pigs had loss of signal in the electromyography during the procedure; only one pig had isolated transient decrease in amplitude and one increase in latency. One pig had transient vocal fold paresis in the group with activation on the nerve. Evaluation of the nerves by histology and immunohistochemistry did not show significant changes attributed to thermal injury. CONCLUSIONS The use of ultrasonic energy close to the RLN is safe, provided that activation time does not exceed the necessary time to safely transect the tissue.

Abstract
Intraoperative continuous neural monitoring (C-IONM) during thyroid surgery has been recognized as a useful tool to identify and confirm recurrent laryngeal nerve integrity. The aim of the present study is to analyze electromyographic features and thresholds for normal vocal fold function in our initial experience with C-IONM in thyroid surgery. C-IONM was utilized in 57 patients who underwent thyroid surgery between July 2012 and December 2015. EMG parameters were analyzed looking for potential predictors of postoperative vocal fold dismotility. There were 54 females (94.7%) and 3 males (5.3%) with a mean age of 46.7 ± 11.6 years. C-IONM was successfully registered in 89 of 107 nerves at risk (83.1%). Mean basal amplitude was 727.31 ± 471.25 μV and mean final amplitude was 650.27 ± 526.87 μV (P = 0.095, CI 95% 13.83-167.91). Mean basal latency was 5.23 ± 1.42 mS and mean final latency was 5.18 ± 1.50 mS (P = 0.594, CI 95% 0.39-0.24). Four patients had transient postoperative vocal fold paresis. None of these four patients had loss of signal (LOS), three had transient decrease in amplitude, and one had a normal registry throughout the operation. C-IONM is a useful tool to identify patients in whom intraoperative RLN is at risk during surgery. Final amplitude above 500 μV and no LOS is associated with RLN integrity and normal postoperative vocal fold function.

Abstract
BACKGROUND One-year results of the VBLOC DM2 study found that intermittent vagal blocking (VBLOC therapy) was safe among subjects with obesity and type 2 diabetes mellitus (T2DM) and led to significant weight loss and improvements in glycemic parameters and cardiovascular risk factors. Longer-term data are needed to determine whether the results are sustained. METHODS VBLOC DM2 is a prospective, observational study of 28 subjects with T2DM and body mass index (BMI) between 30 and 40 kg/m(2) to assess mid-term safety and weight loss and improvements in glycemic parameters, and other cardiovascular risk factors with VBLOC therapy. Continuous outcome variables are reported using mixed models. RESULTS At 24 months, the mean percentage of excess weight loss was 22% (95% CI, 15 to 28, p < 0.0001) or 7.0% total body weight loss (95% CI, 5.0 to 9.0, p < 0.0001). Hemoglobin A1c decreased by 0.6 percentage points (95% CI, 0.2 to 1.0, p = 0.0026) on average from 7.8% at baseline. Fasting plasma glucose declined by 15 mg/dL (95% CI, 0 to 29, p = 0.0564) on average from 151 mg/dL at baseline. Among subjects who were hypertensive at baseline, systolic blood pressure declined 10 mmHg (95% CI, 2 to 19, p = 0.02), diastolic blood pressure declined by 6 mmHg (95% CI, 0 to 12, p = 0.0423), and mean arterial pressure declined 7 mmHg (95% CI, 2 to 13, p = 0.014). Waist circumference was significantly reduced by 7 cm (95% CI, 4 to 10, p < 0.0001) from a baseline of 120 cm. The most common adverse events were mild or moderate heartburn, implant site pain, and constipation. CONCLUSIONS Improvements in obesity and glycemic control were largely sustained after 2 years of treatment with VBLOC therapy with a well-tolerated risk profile.

Abstract
BACKGROUND Advanced bipolar and ultrasonic devices have shown significant reduction in the surgical time of thyroid operations. This randomized, controlled trial assessed if operative time and other relevant outcomes are different for thyroidectomies performed either with a second-generation advanced bipolar device or traditional tie and suture technique. METHODS Forty-one patients were randomized into 2 groups (advanced bipolar device and traditional tie and suture). Secondary end points included estimated blood loss, postoperative hemorrhage or hematoma requiring operative reintervention, recurrent laryngeal nerve injury, hypoparathyroidism, pain intensity, number of ligatures, analgesia usage, and loss of signal during recurrent laryngeal nerve monitoring. RESULTS Preoperative characteristics were similar between both groups. Mean operative time in the advanced bipolar device group was reduced by 32.5 minutes compared with the traditional tie and suture group (P = .006). Intraoperative blood loss was similar in both groups. Four patients presented postoperative vocal cord dysmotility, 3 in the traditional tie and suture group and 1 in the advanced bipolar device group (P = ns). Two of these 4 patients also had a >50% amplitude decrease during continuous intraoperative neuromonitoring, 1 in each group. Pain intensity, 12 hours after operation, was significantly greater in the traditional tie and suture group (P = .015), even though pain medication requirements during the initial 24 hours after operation were similar between groups (P = .97). There were no cases of postoperative hemorrhage or hematoma requiring reintervention. Postoperative, symptomatic hypocalcemia occurred in 6 patients, 4 in the traditional tie and suture, and 2 in the advanced bipolar device group. One of them developed permanent hypocalcemia. CONCLUSION The use of an advanced bipolar device in thyroid operation reduces operative time by >30 minutes, with a similar postoperative outcome profile when compared with the traditional tie and suture technique.

Abstract
Incidental detection of pancreatic neuroendocrine tumors (PNETs) has substantially increased over the last decade due to widespread use of advanced imaging studies. Reliable initial imaging-based characterization is crucial for the differential diagnosis from other exocrine neoplasms and to determine the appropriate management plan. Measurements of chromogranin A, pancreatic polypeptide, and calcitonin are recommended for the biochemical evaluation. A thorough medical history needs to be performed to rule out multiple endocrine neoplasia (MEN) type 1. The European Neuroendocrine Tumor Society (ENETS)/Tumor Node Metastasis (TNM) staging system together with a grading based on the Ki-67 proliferation index and mitotic counts has proven to give more appropriate prognostic information than the World Health Organization (WHO)/American Joint Committee on Cancer (AJCC) TNM staging but may still fail to safely differentiate benign from malignant lesions. Poorly differentiated PNETs generally present with metastases and are rarely amenable for resection. Well- or intermediately differentiated tumors ≥2 cm with imaging evidence of malignancy or with a Ki-67 >2% should be resected. It has been suggested that non-MEN related, nonfunctioning, and asymptomatic PNETs <2 cm with a Ki-67 index ≤2% carry a low risk of metastasis and may be observed in the absence of clinical or radiologic criteria of malignancy or progression, especially in older patients. However, because metastases may occur with long delay with smaller PNETS, physicians should consider patient age, lesion location, and the risks of operation, and patients not undergoing surgery need to be closely followed closely.

Abstract
BACKGROUND Bariatric surgery has proven to provide durable weight loss and control of comorbid conditions, including the metabolic syndrome (MS). Existing definitions of MS have caused substantial confusion regarding their concordance for identifying the same individuals. The aim of this study was to assess the value of 2 different diagnostic guidelines criteria (National Cholesterol Education Adult Treatment Panel III [ATP III] and International Diabetes Federation [IDF]) for the evaluation of remission of MS after Roux-en-Y gastric bypass (RYGB). PATIENTS AND METHODS A cohort of 381 patients who underwent a primary RYGB, satisfied the criteria for MS, and had at least o1 postoperative visit were selected. Weight loss and MS remission were analyzed 6 and 12 months after surgery by ATP III and IDF criteria. RESULTS Before surgery, 381 (48.9%) and 354 (45.4%) patients fulfilled the criteria for MS according to the ATP III and IDF, respectively. According to the ATP III definition, remission of MS after bariatric surgery occurred in 209 of 239 (87.4%) and 98/102 (96.1%) patients at 6 and 12 months, respectively. According to the IDF definition, this occurred in 180 of 232 (77.6%) and 54 of 64 (84.4%) at the same time periods. On the basis of different percentage of excess body weight loss cut-off values, the area under the curve in receiver operating characteristic analysis at 12 months was slightly better for ATP III (0.77) than IDF criteria (0.68) for remission of MS. CONCLUSIONS With the use of the IDF definition, the remission rate of MS was 10% more rigorous than with use of the ATP-III criteria. This feature is attributable to a greater discrimination of patients with high blood pressure, glycemia, and dyslipidemia. The IDF criteria seem more accurate to evaluate MS remission.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is considered the standard treatment for patients with refractory primary immune thrombocytopenia (ITP). PATIENTS AND METHODS All patients with ITP who underwent LS during the last 17 years and who had a minimum follow-up of 1 year were included. Several perioperative variables such as age, platelet count, and duration of preoperative therapy were recorded and analyzed, looking for potential predictive variables of clinical response. RESULTS In total, 150 patients were included: 108 (72%) women and 42 (28%) men, with a mean age of 37.3±15.8 years. In the evaluation 1 year after surgery, 133 (88.7%) patients had achieved complete response, 4 (2.7%) had a response, and in 13 (8.6%) there was no response. None of the analyzed preoperative variables was identified as a predictive factor of response at 1 year. Immediate responders after surgery (≥150,000 platelets/mL during the first week) had a higher platelet count and rate of complete response at 1 year (94.2%). CONCLUSIONS LS has a high success rate in patients with refractory ITP. Potential predictive indicators of success remain to be determined.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) may be a technically challenging surgical technique when features such as thick abdominal wall and increased liver volume are present. Very low calorie diets in the form of liquid meal replacements given 6 weeks prior to surgery have proven to decrease liver volume. The aim of our study was to assess the effect of a 6-week preoperative low calorie/regular diet on liver volume and body weight in morbidly obese patients. METHODS A pilot study was carried out in 20 morbidly obese patients with an 800-kcal diet for 6 weeks. They were followed weekly to ensure proper compliance. CT scan was used for determining liver volume every 2 weeks in order to assess the impact of the diet. Baseline values were taken as controls for every patient as tied measures. Statistical analysis was suitable to variable scaling and performed using SPSS v. 20.0. Parametric and non-parametric test for tied measures were done. Any p value lesser than 0.05 or 5% was considered as statistically significant. RESULTS Twenty patients adhered to the diet intervention for 6 weeks prior to LRYGB. Median ± SD age was 34.5 ± 11.5 years and 17 were female (85%). Heart rate and blood pressure did not vary across the study. Initial median ± SD BMI was 46.02 ± 5.29 kg/m2 (range 38.7-54.8). Repeated and tied measurements across the 6 weeks of treatment within individuals resulted statistically significant for reducing BMI (p < 0.0001). CT scan assessed liver volume initially as a control and in weeks 2, 4 and 6. Parametric and non-parametric assessment for multiple measurements also showed statistical significance among these values (p < 0.0001). Diet tolerability was additionally evaluated with a questionnaire showing more than 80% of acceptability with discrete rates of nausea (15%) and diarrhoea (15%). CONCLUSIONS Based on our results, we demonstrated that a very low calorie diet with home ingredients is capable for effectively reducing body weight and liver size in morbidly obese patients. This relatively short intervention (4 to 6 weeks) was accomplished in all our patients with a high frequency of compliance and a low rate of secondary effects.

Abstract
BACKGROUND Primary adrenal malignancies are rare and have a dismal prognosis. We report our experience in both adrenocortical carcinomas and malignant pheochromocytomas who received medical care at our Institution between 1994 and 2009. MATERIAL AND METHODS The data bases of hospital discharges, surgery and pathology were reviewed looking for patients with diagnosis of primary adrenal malignant tumors. Clinical presentation, laboratory and image characteristics, surgical details, histopathology findings and outcome were analyzed. RESULTS A total of eight patients were identified, two men and six women with a mean age of 48.1 +/- 15.7 years (31-80). Six patients presented with adrenocortical carcinomas and two had malignant pheochromocytomas. Of the six cortical tumors four were functioning. Five were stage II, two were stage III and one was stage IV. All patients underwent surgery as initial treatment. Six patients underwent open and two, laparoscopic adrenalectomy. Three patients received adjuvant chemotherapy. In a mean follow up of 32 +/- 27 months, only three patients with stage II were alive and free of the disease. CONCLUSIONS As in other series, primary adrenal carcinoma in our population proved to be a rare endocrine neoplasm with poor prognosis despite complete surgical resection. Treatment at initial stages provides better outcome.
