Abstract
PURPOSE OF REVIEW Increased morbidity seen with rising obesity rates continues to place an unheralded burden on our health system. Lack of higher bariatric surgery utilization and limitations with lifestyle modification and pharmacotherapy highlights the need for additional therapies for obesity. Endoscopic bariatric and metabolic therapies (EBMT) are effective, safe treatments for obesity. Current FDA-approved EBMT are confined to gastric modalities while small bowel directed therapies are still considered investigational. This review highlights current modalities of EBMT. RECENT FINDINGS Many randomized controlled trials have been performed, including both open label and sham-controlled, which have demonstrated safety and efficacy of EBMT over lifestyle therapy alone. In addition, emerging evidence from clinical experience further supports EBMT for treatment of obesity. Current evidence supports the safety and efficacy of EBMT for obesity treatment in conjunction with lifestyle therapy. They can also be used concurrently with weight loss medications to increase total weight loss.

Obes Surg 2024; 34:2177-2185. [PMID: 38630144 PMCID: PMC11127895 DOI: 10.1007/s11695-024-07222-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/30/2024] [Accepted: 04/10/2024] [Indexed: 05/27/2024]
Abstract
Three-dimensional (3D) laparoscopy has several advantages in gastrointestinal surgery. This systematic review determined whether similar benefits exist for bariatric surgical procedures by systematically searching the MEDLINE, Embase, and Scopus databases. Six studies including 629 patients who underwent 2D (386) and 3D (243) laparoscopic bariatric surgeries were selected. Operative time was significantly shorter in patients undergoing 3D laparoscopic gastric bypass (pooled standardized mean difference [SMD] 1.19, 95% confidence interval [CI] 2.22-0.15). Similarly, a shorter hospital stay was detected both during sleeve gastrectomy (SMD 0.42, 95% CI 0.70-0.13) and gastric bypass (SMD 0.39, 95% CI 0.64-0.14) with 3D laparoscopy. The study showed the potential benefit of 3D imaging in preventing intra- and postoperative complications. Despite the limited evidence, surgeons may benefit from 3D laparoscopy during bariatric surgery.

Abstract
The global obesity problem is becoming increasingly serious, with eight of the top ten causes of death in Taiwan in 2020 being related to obesity. Morbid obesity poses a significant threat to one's health and well-being. In recent years, bariatric surgery has emerged as a more effective treatment option for patients with morbid obesity. However, the procedure is not without risks. This study aims to examine the factors that impact the postoperative efficacy evaluation of patients with morbid obesity. This study uses a retrospective cross-sectional design, with medical records being collected retrospectively. The data was collected from patients who underwent bariatric surgery between July 1, 2017 and June 30, 2020 at a hospital in southern Taiwan. A total of 663 patients were included in the study and were observed for 1 year after the surgery. The independent variables included demographic variables, perceived symptoms variables, perceived lifestyle variables, and surgery-related variables, while the dependent variables included weight loss outcomes and complications. The prognostic factors affecting the postoperative efficacy evaluation of patients with pathological obesity were determined using multiple regression analysis and binary regression analysis. The study found that 65.6% of the participants were female, with an average age of 36.8 years. The results of the multiple regression and binary logistic regression showed that gender, age, BMI, diabetes, and smoking habit were the predictors of postoperative weight loss. Hypertension, diabetes, liver disease, kidney disease, smoking habit, drinking habit, and operation time were the predictors of postoperative complications. The study found that the presence of the aforementioned 12 significant factors can affect the success of weight loss after surgery and the incidence of postoperative complications. This information can serve as a reference for clinical care institutions and patients to improve the postoperative efficacy evaluation.

Abstract
Nearly 60% of asthmatics in the USA suffer from obesity. Asthma is a comorbid condition alongside obesity, commonly accompanied by conditions such as hypertension and type 2 diabetes. The positive effect of bariatric surgery on patients suffering from hypertension and type 2 diabetes, which leads to either a reduction in the dose of medication taken for the aforementioned diseases or the withdrawal of the disease, is quite well proven in the literature. Currently, the impact of bariatric operations on the control and course of bronchial asthma and pharmacological treatment has not been fully recognized and described, requiring further research; therefore, the following review of the literature was conducted.

Abstract
INTRODUCTION It is well established that microvascular structures are affected in obese people with metabolic disease. We aimed to evaluate the effect on microvascular structures by examining macular and peripapillary vessel density with optical coherence tomography angiography after bariatric surgery in obese individuals without metabolic disease. METHODS This prospective study included 96 eyes of 48 obese patients. Body mass index (BMI), macular vessel density in the superficial, intermediate, and deep capillary plexus, and peripapillary vessel density were measured before and 6 months after bariatric surgery. RESULTS BMI decreased significantly to 43.75 ± 4.4 kg/m2 postoperatively compared to 55.31 ± 5.1 kg/m2 preoperatively (p < 0.05). A significant increase was observed in macular vessel density in the deep capillary plexus postoperatively (p < 0.01). However, no significant postoperative increase occurred in macular vascular density in the superficial and intermediate capillary plexus (p > 0.05). Moreover, there was no change in peripapillary vascular density (p > 0.05). Postoperative thickening of the foveal, parafoveal, and perifoveal retinal layers was significant (p < 0.001). No significant correlation was detected between BMI change and macular and peripapillary vessel density changes (p > 0.05). CONCLUSION An increase in macular vascular density, particularly in the deep capillary plexus, and retinal layer thickness has been observed following bariatric surgery performed on obese individuals without metabolic disease. This increase may indicate that microvascular structures are affected even in the absence of metabolic disease and that microperfusion improves with surgery.

Abstract
This study aimed to retrospectively analyze the perioperative and postoperative follow-up data of patients with super obesity who had undergone RYGB, SG, BPD/DS, and SADI-S. A retrospective observational study was conducted to analyze the perioperative and postoperative follow-up data of 60 patients with super obesity who had undergone bariatric surgery. A total of 34 men and 26 women were included in this study. The participants had an average preoperative BMI of 53.81 ± 3.25 kg/m2. The body weight and BMI of all four patient groups decreased significantly at 3, 6, and 12 months postoperatively compared with the preoperative values. Additionally, the TWL (%) and EWL (%) of all four groups increased gradually over the same period. Compared with the preoperative values, the systolic and diastolic blood pressure, glycosylated hemoglobin, uric acid, triglycerides, and total cholesterol decreased to varying degrees in the four groups 1 year postoperatively. RYGB, SG, BPD/DS, and SADI-S are all safe and effective in treating super obese patients and improving their metabolic diseases to a certain extent.

Abstract
BACKGROUND Single-anastomosis metabolic/bariatric surgery procedures may lessen the incidence of anastomotic complications. This study aimed to evaluate the feasibility and safety of performing side-to-side duodenoileal (DI) bipartition using magnetic compression anastomosis (MCA). In addition, preliminary efficacy, quality of life (QoL), and distribution of food through the DI bipartition were evaluated. METHODS Patients with a body mass index (BMI) of ≥35.0 to 50.0 kg/m2 underwent side-to-side DI bipartition with the magnet anastomosis system (MS) with sleeve gastrectomy (SG). By endoscopic positioning, a distal magnet (250 cm proximal to the ileocecal valve) and a proximal magnet (first part of the duodenum) were aligned with laparoscopic assistance to inaugurate MCA. An isotopic study assessed transit through the bipartition. RESULTS Between March 14, 2022 to June 1, 2022, 10 patients (BMI of 44.2 ± 1.3 kg/m2) underwent side-to-side MS DI. In 9 of 10 patients, an SG was performed concurrently. The median operative time was 161.0 minutes (IQR, 108.0-236.0), and the median hospital stay was 3 days (IQR, 2-40). Paired magnets were expelled at a median of 43 days (IQR, 21-87). There was no device-related serious advanced event within 1 year. All anastomoses were patent with satisfactory diameters after magnet expulsion and at 1 year. Respective BMI, BMI reduction, and total weight loss were 28.9 ± 1.8 kg/m2, 15.2 ± 1.8 kg/m2, and 34.2% ± 4.1%, respectively. Of note, 70.0% of patients reported that they were very satisfied. The isotopic study found a median of 19.0% of the meal transited through the ileal loop. CONCLUSION Side-to-side MCA DI bipartition with SG in adults with class II to III obesity was feasible, safe, and efficient with good QoL at 1-year follow-up. Moreover, 19% of ingested food passed directly into the ileum.

Abstract
We reviewed the available evidence on the outcome of metabolic and bariatric surgery (MBS) in patients with pulmonary hypertension (PH). Five studies examining 174 patients were included; the mean age was 54.5 ± 9.27 years; the mean BMI before surgery and at the end of follow-up were 47.2 ± 5.95 kg/m2 and 37.4 ± 2.51 kg/m2, respectively. Furthermore, the results showed a significant decrease in the right ventricle systolic pressure (RVSP) after MBS with a mean difference of 10.11% (CI 95%: 3.52, 16.70, I2 = 85.37%, p = < 0.001), at 16.5 ± 3.8 month follow-up with a morbidity rate of 26% and 0 mortality. Thirty-day postoperative complications included respiratory failure, pulmonary embolism, pulmonary edema, and anastomotic leak. There appears to be a significant improvement in PH with a decrease in medication requirements after MBS.

Abstract
Bariatric surgery is currently the most effective long-term treatment for morbid obesity as well as type-2 diabetes mellitus. The field of metabolic and bariatric surgery has seen tremendous growth over the past decade with dramatically reduced risks. This article aims to provide an update on bariatric surgery, highlighting the latest outcomes, improvements, and challenges in the field. Recently, the American Society of Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) released a major update to the indications for bariatric surgery at BMI ≥35 kg/m2 regardless of co-morbidities and 30-34.9 kg/m2 with obesity-related comorbidities. Sleeve gastrectomy has emerged as the most popular bariatric procedure in the last 10 years with its remarkable efficacy and safety profile. The implementation of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) and Enhanced Recovery After Surgery (ERAS) protocols have significantly improved the quality of care for all bariatric patients. The recent introduction and FDA approval of Glucagon-Like Peptide-1 (GLP-1) agonists for chronic obesity has garnered significant media coverage and popularity, but no guidelines exist regarding its use in relation to bariatric surgery. This update underscores the need for tailored approaches, ongoing research, and the integration of evidence-based medicine and innovations to enhance patient care.

Abstract
INTRODUCTION The International Federation for Surgery for Obesity and Metabolic Disorders (IFSO) Global Registry aims to provide descriptive data about the caseload and penetrance of surgery for metabolic disease and obesity in member countries. The data presented in this report represent the key findings of the eighth report of the IFSO Global Registry. METHODS All existing Metabolic and Bariatric Surgery (MBS) registries known to IFSO were invited to contribute to the eighth report. Aggregated data was provided by each MBS registry to the team at the Australia and New Zealand Bariatric Surgery Registry (ANZBSR) and was securely stored on a Redcap™ database housed at Monash University, Melbourne, Australia. Data was checked for completeness and analyzed by the IFSO Global Registry Committee. Prior to the finalization of the report, all graphs were circulated to contributors and to the global registry committee of IFSO to ensure data accuracy. RESULTS Data was received from 24 national and 2 regional registries, providing information on 502,150 procedures. The most performed primary MBS procedure was sleeve gastrectomy, whereas the most performed revisional MBS procedure was Roux-en-Y gastric bypass. Asian countries reported people with lower BMI undergoing MBS along with higher rates of diabetes. Mortality was a rare event. CONCLUSION Registries enable meaningful comparisons between countries on the demographics, characteristics, operation types and approaches, and trends in MBS procedures. Reported outcomes can be seen as flags of potential issues or relationships that could be studied in more detail in specific research studies.

Abstract
BACKGROUND We previously demonstrated how kidney injury in patients with morbid obesity can be reversed by bariatric surgery (BaS). OBJECTIVE(S) Based on previous experience, we hypothesize patients' potentially reversible kidney injury might be secondary to reduction in renal blood flow (RBF), which improves following BaS. SETTING Academic Hospital. METHODS We conducted a retrospective analysis of patients who underwent BaS at our institution from 2002 to 2019. We identified patients with chronic kidney disease (CKD) using the estimated glomerular filtration rate (eGFR) from the CKD Epidemiology Collaboration Study (CKD-EPI) classification system. We used the BUN/Creatinine (Cr) ratio pre- and postoperatively to determine a prerenal (decreased RBF) versus intrinsic component as the responsible cause of CKD in this patient population. Decreased RBF was defined as BUN/Cr > 20 preoperatively. RESULTS Our analysis included n = 2924 patients, of which 11% (n = 325) presented decreased RBF. From our original sample, only n = 228 patients had the complete data necessary to assess both eGFR and RBF (BUN/Cr). Patients with baseline CKD stage 2 demonstrated preoperative BUN/Cr 20.85 ± 10.23 decreasing to 14.99 ± 9.10 at 12-month follow-up (P < .01). Patients with baseline CKD stage 3 presented with preoperative BUN/Cr 23.88 ± 8.75; after 12-month follow-up, BUN/Cr ratio decreased to 16.38 ± 9.27 (P < .01). Patients with CKD stage 4 and ESRD (eGFR < 30) did not demonstrate a difference for pre- and postoperative BUN/Cr 21.71 ± 9.28 and 19.21 ± 14.58, respectively. CONCLUSION(S) According to our findings, patients with CKD stages 1-3 present improvement of their kidney function after BaS. This amelioration could be secondary to improvement of the RBF, an unstudied reversible mechanism of kidney injury in the bariatric population.

Abstract
INTRODUCTION Obesity is a chronic disease with significant health implications. Bariatric surgery is an effective treatment for obesity-related conditions. However, the timing of post-bariatric body contouring surgery remains uncertain. MATERIALS AND METHODS We conducted a retrospective study of 1336 patients who underwent bariatric surgery. We analyzed weight trends and variations after different types of bariatric procedures. The Pittsburgh Index was used to evaluate body contouring outcomes. RESULTS The majority of patients were women, and sleeve gastrectomy was the most common procedure. Weight loss varied depending on the surgery type, with different outcomes for male and female patients. The Pittsburgh Index remained stable in most cases. CONCLUSION Our findings suggest that the timing of body contouring surgery should be tailored to the type of bariatric procedure performed. Abdominoplasty is recommended as a last procedure for sleeve gastrectomy patients, while gastric bypass patients are suitable candidates for early abdominoplasty. Biliopancreatic diversion patients should stabilize their weight before abdominoplasty. The Pittsburgh Index is a valuable tool for assessing the timing of post-bariatric plastic surgery. Further research is needed to optimize surgical planning and outcomes. LEVEL OF EVIDENCE V This journal requires that authors assign a level of evidence to each article.

Abstract
In a groundbreaking surgical collaboration, a team of surgeons in Lithuania successfully performed the first single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) operation under the remote telemonitoring guidance of a highly experienced surgeon from Spain.The Lithuanian surgical team, comprising skilled bariatric surgeons, meticulously prepared for the SADI-S operation under the remote guidance of their Spanish proctor. Utilizing video conferencing and real-time communication, the mentor provided step-by-step instructions, shared insights, and addressed any concerns during the procedure. The mentor's extensive experience and guidance ensured a safe and successful surgical outcome.This innovative approach not only demonstrates the potential of telemedicine in the field of complex bariatric surgeries but also highlights the power of international cooperation in advancing surgical techniques and patient care by using modern methods of telemedicine and proctorship.

Abstract
BACKGROUND Bariatric surgery is a procedure for people with class II and III obesity who are unable to lose weight using traditional methods. The incidence rate of bariatric surgery in reproductive-age women is increasing rapidly, so the number of women who become pregnant after bariatric surgery is rising. AIM To collate and synthesise available literature regarding breastfeeding following bariatric surgery. METHODS This review was reported by the preferred reporting items for systematic reviews and meta-analysis extension for scoping reviews (PRISMA-Scr). The review included peer-reviewed research studies and research-based conference abstracts on breastfeeding outcomes in mothers who have undergone bariatric surgery before pregnancy. Health databases were searched from 1990 to December 2023. Included studies were analysed using a narrative synthesis. FINDINGS From 1506 abstracts, 16 papers were identified. Three themes emerged from the analysis: challenges in exclusive breastfeeding, nutritional composition in breast milk, and breastfeeding experience. There was a tendency for lower breastfeeding rates and shorter durations in mothers who had bariatric surgery. Most studies focussed on the nutritional composition of breast milk however these results were mixed. Only three articles were qualitative, and their findings showed that women wanted more information and support about breastfeeding following bariatric surgery. DISCUSSION Our review indicates breastfeeding challenges in post-bariatric surgery mothers and reduced breastfeeding rates. It is unclear whether bariatric surgery impacts the nutritional quality of breast milk due to inconsistent study outcomes. CONCLUSION Future research is essential, specifically on understanding the breastfeeding concerns and experiences of women who have undergone bariatric surgery.

[PMID: 38528214 PMCID: PMC11031430 DOI: 10.1007/s11695-024-07191-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 03/19/2024] [Accepted: 03/20/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND Obesity is a risk factor for hyperuricemia and gout, while weight reduction can reduce urate levels. The aim of this study was to examine the effect of bariatric surgery on longitudinal serum urate levels. METHODS We performed a retrospective observational study of 283 patients who had undergone bariatric surgery [237 (83.7%) gastric bypass, 34 (12.0%) sleeve gastrectomy and 12 (4.2%) gastric banding] and were followed up for 2 years. The results shown represent mean (standard deviation). RESULTS Bariatric surgery was associated with significant reduction in serum urate from baseline level of 0.343 (0.086) mmol/L to 0.296 (0.076) mmol/L (p < 0.001) at 12 months and 0.286 (0.073) mmol/L (p < 0.001) at 24 months, including in men and women, and in patients with or without diabetes. Patients with elevated urate levels at baseline, who comprised 27.2% of the total cohort, achieved reduction in levels by 4 months. CONCLUSION Bariatric surgery leads to significant reduction in serum urate levels at 12 and 24 months. This could reduce incidence of gout and need for prophylactic medication(s).

Abstract
BACKGROUND The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program designated bariatric surgery as a clinical pathway. Among the tiers of the Masters Program, revisional bariatric surgery is the highest tier of "mastery" within the pathway. This article presents the top 10 seminal studies representing the current landscape of revisional bariatrics. METHODS The literature was systematically searched and seminal articles designated by consensus agreement of the SAGES Metabolic and Bariatric Surgery committee using multiple criteria, including impact on the field, citation frequency, and expert opinion. Articles were reviewed by committee members and presented in summarized fashion. RESULTS The top 10 papers are presented in grouped thematic categories covering the early evolution of revisional bariatrics, changing criteria for reoperative bariatric surgery, divergence of revision versus conversion bariatric surgery, and recent technologic innovations in revisional bariatric surgery. Each summary is presented with expert appraisal and commentary. CONCLUSION These seminal papers represent a snapshot of the dynamic field of revisional bariatric surgery and emphasize the need to not only remain current with contemporary trends but also keep a patient-oriented perspective on patient and intervention selection for optimal success.

Patient and operative factors influence delayed discharge following bariatric surgery in an enhanced recovery setting. Surg Obes Relat Dis 2024; 20:446-452.

Abstract
BACKGROUND Enhanced Recovery After Surgery (ERAS) programs have been widely adopted in bariatric surgery. However, not all patients are successfully managed in the ERAS setting and there is currently little way of predicting the patients who will deviate from the program. Early identification of these patients could allow for more tailored protocols to be implemented preoperatively to address the issues, thereby improving patient outcomes. OBJECTIVES The aim of this study was to elucidate the factors which preclude discharge by comparing patients who were successfully discharged by the end of the first postoperative day (POD 0/1) to those who stayed longer, including revisional surgery in this analysis. SETTING A tertiary, high-volume Bariatric Centre, United Kingdom. METHODS A retrospective analysis was performed of all patients undergoing bariatric surgery in a single centre in 1 year. Multivariate analyses compared patient and operative variables between patients who were discharged on POD 0/1 and those who stayed longer. RESULTS A total of 288 bariatric operations were performed: 78% of operations performed were laparoscopic Roux-en-Y gastric bypass; 22% laparoscopic sleeve gastrectomy. Of these cases, 13% were revisional operations. Four patients returned to theatre on the index admission. 81% of patients were discharged by POD 0/1. A re-presentation within 30 days was seen in 6% of patients. There was no significant difference in length of stay for the type of operation performed (P = .86). Patients who had a revisional procedure were not more likely to stay longer. Length of stay was also independent of age, BMI, and comorbidities. Caucasian patients were more likely to be discharged on POD 0/1 than those of other ethnicities (90% versus 78%; P = .02). Operations performed by trainee surgeons, under consultant supervision, were significantly more likely to be discharged on POD 0/1 (P = .03). However, a logistic regression analysis was unable to predict patients who had a prolonged stay. CONCLUSIONS Patient length of stay is independent of BMI, operation, and comorbidities and these factors do not need special consideration in ERAS pathways. Patients undergoing revisional procedures can be managed in the same way as those having primary procedures, with a routine POD 0/1 discharge. However, the impact of individual patient factors, and their interaction, is complex and cannot predict overstay.

Abstract
BACKGROUND The rates of postoperative complications can vary among specific patient populations. OBJECTIVES The aim of this study is to examine how gender, race, and ethnicity can affect short-term postoperative complications in bariatric surgery patients. SETTING United States. METHODS Patients who underwent bariatric surgery between the years 2016 and 2021 were included and stratified based on gender, race/ethnicity, and procedure type. The 30-day outcomes were assessed using Clavien-Dindo (CD) classification of III-V. Wilcoxon rank-sum test was performed to compare continuous variables among groups and Chi-squared test for categorical variables. Logistic regression was performed to examine the effects of gender, race/ethnicity on CD classification ≥ III complications by the procedure type. RESULTS A total of 975,642 bariatric surgery patients were included. Descriptive univariate analysis showed that CD ≥ III complications were higher among non-Hispanic blacks (NHB) and lowest in Hispanic patients, regardless of their gender, except in the duodenal switch DS group, where non-Hispanic whites (NHW) had the lowest complication rate. There was no difference between male and female patients with regards to postoperative complications, except in the sleeve gastrectomy (SG) group, where NHW males had more complications than NHW females. Sleeve gastrectomy showed the lowest complication rates followed by gastric bypass and DS in all groups. In multivariate logistic regression model, for both females and males NHBs had higher odds of postoperative complications compared to NHWs in sleeve gastrectomy (Female aOR:1.31, 95% CI: [1.23-1.40]; Male aOR:1.24, 95% CI: [1.08-1.43], P < .001) and gastric bypass (Female aOR:1.24, 95% CI: [1.16-1.33]; Male aOR:1.25, 95% CI: [1.06-1.48], P < .01). CONCLUSIONS Non-Hispanic Black patients are at a higher rate of developing CD ≥ III complications compared to non-Hispanic Whites after bariatric surgery. The male gender was not a significant risk factor for serious postoperative complications. Among the different types of bariatric procedures, sleeve gastrectomy has the lowest rates of severe complications, followed by gastric bypass and duodenal switch. These results highlight the significance of considering gender, race, ethnicity, and procedure type during preoperative evaluation, surgical planning, and postoperative care.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS), despite being the most effective durable treatment for obesity, remains underused as approximately 1% of all qualified patients undergo surgery. The American Society for Metabolic and Bariatric Surgery established a Numbers Taskforce to specify the annual rate of obesity treatment interventions utilization and to determine if patients in need are receiving appropriate treatment. OBJECTIVE To provide the best estimated number of metabolic and bariatric procedures being performed in the United States in 2022. SETTING United States. METHODS We reviewed data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program and National Surgical Quality Improvement Program. In addition, data from industry and state databases were used to estimate activity at non-accredited centers. Data from 2022 were compared mainly with data from the previous 2 years. RESULTS Compared with 2021, the total number of MBS performed in 2022 increased from approximately 262,893 to 280,000. The sleeve gastrectomy (SG) continues to be the most commonly performed procedure. The gastric bypass procedure trend remained relatively stable. The percentage of revision procedures and biliopancreatic diversion with duodenal switch procedures increased slightly. Intragastric balloon placement increased from the previous year. Endoscopic sleeve gastroplasty increased in numbers. CONCLUSIONS There was a 6.5% increase in MBS volume from 2021 to 2022 and a 41% increase from 2020, which demonstrates a recovery from the COVID-19 pandemic. SG continues to be the most dominant MBS procedure.

Abstract
Metabolic and bariatric surgery (MBS) leads to long-term weight loss, reduced risk of cardiovascular events and cancer, and reduced mortality. Sleeve gastrectomy and Roux-en-Y gastric bypass are currently the most common surgical techniques. Weight loss after MBS was previously believed to work through restriction and malabsorption, however, mechanistic studies show that MBS techniques with long term efficacy instead alter physiological signaling between the gut and the brain. In revisional MBS, the initial surgical technique is corrected, modified, or converted to a new one. The indication for revisional MBS can be to achieve further weight loss or improvement in obesity comorbidity, but it may be necessary due to complications (e.g., gastroesophageal reflux or obstruction). Revisional MBS is associated with an increased risk of surgical complications and often less weight loss compared to the results following primary surgery. This narrative review summarizes data from revisional MBS where information is often presented with inconsistent definitions for indications and outcomes, making comparison between strategies difficult. In summary, we suggest careful weighing of potential benefits and risks with revisional MBS, bearing in mind the option of add-on therapy with new anti-obesity drugs.

Abstract
OBJECTIVE To describe the outcomes of kidney transplant (KT) candidates with obesity undergoing sleeve gastrectomy (SG) to meet the criteria for KT. METHODS Retrospective analysis was conducted of electronic medical records of KT candidates with obesity (body mass index >35 kg/m2) who underwent SG in our institution. Weight loss, adverse health events, and the listing and transplant rates were abstracted and compared with the nonsurgical cohort. RESULTS The SG was performed in 54 patients; 50 patients did not have surgery. Baseline demographic characteristics were comparable at the time of evaluation. Mean body mass index ± SD of the SG group was 41.7±3.6 kg/m2 at baseline (vs 41.5±4.3 kg/m2 for nonsurgical controls); at 2 and 12 months after SG, it was 36.4±4.1 kg/m2 and 32.6±4.0 kg/m2 (P<.01 for both). In the median follow-up time of 15.5 months (interquartile range, 6.4 to 23.9 months), SG was followed by active listing (37/54 people), and 20 of 54 received KT during a median follow-up time of 20.9 months (interquartile range, 14.7 to 28.3 months) after SG. In contrast, 14 of 50 patients in the nonsurgical cohort were listed, and 5 received a KT (P<.01). Three patients (5.6%) experienced surgical complications. There was no difference in overall hospitalization rates and adverse health outcomes, but the SG cohort experienced a higher risk of clinically significant functional decline. CONCLUSION In KT candidates with obesity, SG appears to be effective, with 37% of patients undergoing KT during the next 18 months (P<.01). Further research is needed to confirm and to improve the safety and efficacy of SG for patients with obesity seeking a KT.
