Riesgo cardiovascular, dislipemias e indicación de estatinas en una población de obesos mórbidos

Introducción: La obesidad se relaciona con un riesgo cardiovascular (RCV) elevado. Esto nos obliga a tomar conductas terapéuticas y prevencionistas. El objetivo de este trabajo es evaluar el riesgo cardiovascular en una población de obesos mórbidos y valorar la correcta indicación de estatinas. Metodología: Estudio transversal, descriptivo, observacional, con la población obesos mórbidos del Programa de Obesidad y Cirugía Bariátrica (POCB) del Hospital Maciel, desde noviembre del 2014 a marzo del 2020. El RCV se valoró con la calculadora de la organización panamericana de la salud. La indicación de estatinas se consideró según RCV o diagnóstico de dislipemia. Resultados: Se analizaron 478 pacientes, el 84.3% fueron mujeres, la mediana para la edad fue de 44 años, y para el IMC 50 kg/m2. Se calculó un RCV bajo para el 57% de los pacientes; y alto o muy alto para un 37%. La prevalencia de las dislipemias fue 84,3%, a predominio de hipercolesterolemia (33,7%) y dislipemia aterogénica (19,5%). El 60.6% (290) de los pacientes presenta indicación de tratamiento con estatinas, solo el 38.9%. (113) las recibe. El 38.1% (43) alcanzan los objetivos terapéuticos. Conclusiones : La obesidad presenta múltiples comorbilidades que aumentan el RCV, aun así se encuentra subestimada por las calculadoras de riesgo. Queda en evidencia un infratratamiento farmacológico de estos pacientes, no logrando los objetivos terapéuticos propuestos.

Introduction: Obesity is related to a high cardiovascular risk (CVR). This forces us to take therapeutic and preventive behaviors. The objective of this work is to evaluate cardiovascular risk in a morbidly obese population and assess the correct indication of statins. Methodology: Cross-sectional, descriptive, observational study, with the morbidly obese population of the Obesity and Bariatric Surgery Program (POCB) of the Maciel Hospital, from November 2014 to March 2020. CVR was assessed with the calculator of the Pan-American health organization. The indication for statins was considered according to CVR or diagnosis of dyslipidemia. Results: 478 patients were analyzed, 84.3% were women, the median age was 44 years, and the BMI was 50 kg/m2. A low CVR was calculated for 57% of patients; and high or very high for 37%. The prevalence of dyslipidemia was 84.3%, with a predominance of hypercholesterolemia (33.7%) and atherogenic dyslipidemia (19.5%). 60.6% (290) of patients have an indication for treatment with statins, only 38.9%. (113) receives them. 38.1% (43) achieved therapeutic objectives. Conclusions: Obesity presents multiple comorbidities that increase CVR, yet it is underestimated by risk calculators. Pharmacological undertreatment of these patients is evident, not achieving the proposed therapeutic objectives.

Provision and outcomes of publicly funded bariatric surgery in a metropolitan versus a provincial population of New Zealand.

BACKGROUND: Obesity is an important health problem worldwide. The prevalence of obesity in Aotearoa New Zealand (AoNZ) is the third highest amongst OECD countries. Previous studies have demonstrated inequity in the provision of bariatric and metabolic surgery (BMS) across AoNZ, but detailed data regarding patients and surgical outcomes is lacking. The aim of this study is to examine the rates and outcomes of BMS between patients domiciled in a metropolitan versus provincial area in AoNZ. METHODS: A 5-year retrospective observational cohort study of all patients who received BMS domiciled in a metropolitan or a provincial area in the Northern region of AoNZ was performed. Interrogation of patient electronic medical records and clinical notes was performed to collect the required baseline characteristics, secondary outcome measure data and confirm domicile. RESULTS: The rate of BMS was 6.1 times higher in the population with class III obesity domiciled in the metropolitan versus the provincial population. Patients in the metropolitan area were less obese, had lower rates of diabetes and had a wider range of procedures performed. Maori were underrepresented in both cohorts. There was a higher resolution of diabetes in the provincial patients. CONCLUSION: This study has highlighted significant differences in the rate, type and outcomes of BMS between a metropolitan and provincial area in the Northern region of AoNZ. This represents a significant health inequity. Changes in national and regional policies are needed to ensure equitable care for patients with obesity in AoNZ.

Lifestyle intervention and support preferences to maximize health outcomes in adolescent bariatric surgery patients.

Introduction: Metabolic and bariatric surgery (MBS) is safe and efficacious for adolescents with severe obesity. Pairing MBS with behavioral lifestyle interventions may be effective for optimizing treatment outcomes. However, no standardized program exists. Adolescent perspectives are critical to understanding how to design interventions to enhance engagement, sustain motivation, and meet informational needs for pre- and post-MBS self-management behaviors. The aim of this study was to develop an MBS lifestyle support intervention built on evidence-based content with input from adolescents and their families. Methods: A mixed-methods design identified adolescent preferences for MBS lifestyle support. Data were collected from a racially and ethnically diverse sample of adolescents (N = 17, 76% females, 24% males 41.2% non-Hispanic Black, 41.2% Hispanic/Latino, 11.8% non-Hispanic White, 5.8% Other) and their mothers (N = 13, 38.4% Hispanic) recruited from an MBS clinic. Quantitative surveys and qualitative interviews assessed preferred types of pre-post MBS content, modality, frequency, and delivery platforms to inform the design of the intervention. Mixed methods data were triangulated to provide a comprehensive understanding of adolescent/parent preferences. Results: Adolescents prioritized eating well, managing stress, and maintaining motivation as desired support strategies. Parents identified parental support groups and nutrition guidance as priorities. Peer support and social media platforms were identified as key approaches for boosting motivation and engagement. Conclusions: The patient voice is an important first step in understanding how, and whether behavioral lifestyle programs combined with MBS for weight management can be optimized. Adolescent preferences may enhance program fit and identify health behavior supports needed to sustain behavior change.

A review of brain structural and functional changes using MRI technology in patients who received bariatric surgery.

According to the World Health Organization, obesity is one of the most significant health issues currently because it increases risk for type 2 diabetes and cancer, heart disease, bone health, reproduction, and quality of living and it impacts approximately 500 million adults worldwide. This review analyzed the existing literature focusing on the effects of Metabolic and bariatric surgeries (MBS), including Roux-en-Y gastric bypass and sleeve gastrectomy on changes in brain function and anatomy using magnetic resonance imaging (MRI) technology. A PubMed search using the key words bariatric surgery and MRI conducted in December 2023 resulted in 544 articles. Our literature review identified 24 studies addressing neuroanatomic, neurophysiological, cognitive, and behavioral changes that occurred at different time intervals after different types of bariatric surgery. Our review of the literature found several reports indicating that MBS reverse neuroanatomic alterations and changes in functional connectivity associated with obesity. There were also reported improvements in cognitive performance, memory, executive function, attention, as well as decreased gustatory brain responses to food cues and resting state measures following bariatric surgery. There were instances of improved neural functioning associated with weight loss, suggesting that some neuroanatomic changes can be reversed following weight loss induced by bariatric surgery. Additionally, there were data suggesting that brain connectivity and metabolic health are improved following a bariatric surgical intervention. Together, the existing literature indicates an overall improvement in brain connectivity and health outcomes following bariatric surgery.

Conversion of one-anastomosis gastric bypass to Roux-En-Y gastric bypass: mid-term results from the United Arab Emirates.

BACKGROUND: One-Anastomosis Gastric Bypass (OAGB) is becoming popular, but some patients may need to convert to Roux-en-Y Gastric Bypass (RYGB) due weight-related difficulties or postoperative complications. The data on conversions is currently limited to 30-day or short-term follow-up studies. As such, the objective of this study was to evaluate the indications and mid-term outcomes for OAGB conversions to RYGB at a tertiary referral center in the United Arab Emirates. METHODS: A retrospective analysis was conducted on patients who underwent conversion from OAGB to RYGB between February 2016 and May 2023. Demographic information, indications for conversion, intraoperative details, and mid-term outcomes were collected and analyzed. RESULTS: Sixty-four patients underwent conversion from previous OAGB to RYGB. The cohort was 73.4% female (n = 47) with a mean age of 40.8 years. Indications for conversion included acid reflux (n = 28, 43.7%), intractable nausea/vomiting (n = 20, 31.2%), protein-calorie malnutrition (n = 7, 10.9%), anastomotic ulcer (n = 6, 9.3%) and weight recidivism (n = 3, 4.7%). The mean operative time was 238 ± 78.3 min. During the procedure, three intraoperative complications occurred: two cases of bleeding and one case of bowel perforation; all successfully addressed during surgery. The median hospital stay was 3 ± 15.8 days. Three patients (4.6%) experienced major postoperative complications comprising 2 anastomotic leaks and 1 small bowel obstruction. The mean follow-up time was 26.2 ± 19.7 months, with 96.2% of patients reporting resolution of symptoms. There were no mortalities. CONCLUSIONS: Acid reflux is representing 43.7% of the indications for conversion from OAGB to RYGB. The symptom resolution rate holds significance, standing at a remarkable 96.8%. Despite surgical technique advancements, the complication rate after conversions remains significant at 4.6%, with no mortality reported. OAGB patients should be informed about these risks prior to undergoing conversions from OAGB to RYGB.

A Unique Case of Gastric Band Tubing Eroding Into the Vaginal Cuff.

We present here the case of a woman in her 40s with a history of an adjustable gastric band placed a decade ago. After the initial procedure, she had issues with a port-site hernia, mesh placement, and explantation secondary to mesh infection. Her port was removed at the time, with the tubing left in situ with hopes of future salvage. She then presented to her gynecologist with the tubing eroding through her vaginal cuff. This case highlights the importance of having a high index of suspicion in patients with a history of gastric bands given the varying presentation in the event of a complication.

Endoscopic Management of Dysfunctioning Gastric Band after Sleeve Gastrectomy with the Luso-Cor® Esophageal Stent.

Sleeve gastrectomy (SG) can be aided by the addition of a calibration silicone ring, banded SG (BSG). It provides better weight loss than non-banded SG but with higher rate of adverse events. The aim of this case report is to further contribute to the knowledge of how to endoscopically manage these patients by placing a new esophageal stent (Luso-Cor®). A 58-year-old female with grade III obesity (weight 110 kg, BMI: 45.2 kg/m2) underwent SG in 2013. Due to the limited weight loss, a surgical calibration silicon ring was placed in 2017. In the following months, she developed recurrent and abundant postprandial regurgitation, achieving a minimum weight of 66 kg (BMI: 27.1 kg/m2). Gastroesophageal transit showed a stricture at the junction of the gastric corpus and antrum, causing gastric outlet obstruction. Endoscopy identified a regular luminal stenosis with normal mucosa, which allowed easy passage of the endoscope with slight pressure. Two sessions of endoscopic dilatation were performed, first with an 18-mm through-the-scope balloon and later with a 30-mm pneumatic balloon without symptomatic relief. A two-step endoscopic therapeutic approach was proposed to first promote intragastric ring erosion by placing a new partially covered metallic stent, Luso-Cor® esophageal stent 30/20/30 × 240 mm, and subsequently retrieve the stent, followed by cutting and retrieval of the ring. The proximal flare with a 30 mm diameter was placed in the distal esophagus and the distal edge in the prepyloric antrum. However, 2 weeks later, she complained of vomiting and abdominal fullness. Complete migration of the proximal flare of the stent into the remnant gastric fundus was seen on the contrast study. Endoscopy was performed, and the stent was easily removed. A blue calibration ring, partially eroded into the gastric lumen, was observed at the site of gastric tube stenosis. After stent removal, the patient was asymptomatic, and so conservative follow-up was decided. A follow-up endoscopy, performed 5 months later, showed complete reepithelization of the eroded ring. The patient remains asymptomatic after 3 years of follow-up and has regained weight up to 76 kg (BMI: 31.2 kg/m2). The efficacy of endoscopy on the management of ring-related adverse events has been previously reported. Small-case series describe the use of multiple pneumatic dilations or the deployment of plastic or covered metallic stents to cause erosion of the overlying mucosa, followed by cutting and retrieval of the ring. In conclusion, we believe that the mural pressure exerted by the Luso-Cor® esophageal stent, in the limited period it remained in situ, was sufficient to relieve the luminal pressure of the silicon ring, realigning the ring with the remnant gastric tube. This rare clinical entity highlights the potential role of specific metallic stents in the management of these patients.

A cirurgia bariátrica de gastrectomia vertical (sleeve gástrico) pode ser complementada pela adição de um anel restritivo de silicone ­ sleeve gástrico com anel de silastic. O acréscimo deste anel promove uma maior perda de peso, no entanto está associado a maior risco de eventos adversos. O objetivo da apresentação deste caso é contribuir para as diferentes técnicas úteis no tratamento das complicações relacionadas com o anel, através da utilização de uma prótese esofágica (Luso-Cor®).Uma doente de 58 anos, com obesidade grau III (peso 110 kg, IMC 45,2 kg/m2), foi submetida a um sleeve gástrico em 2013. Não apresentou perda de peso favorável e, em 2017, foi colocado um anel de silicone rodeando o tubo gástrico. Nos meses seguintes desenvolveu regurgitação pós-prandial recorrente e abundante, alcançando um peso mínimo de 66 kg (IMC 27,1 kg/m2). Realizou um trânsito gastroesofágico que revelou uma estenose na junção do corpo com o antro gástrico, com evidência de obstrução do esvaziamento gástrico. A endoscopia digestiva alta identificou uma estenose regular recoberta por mucosa sem lesões, com passagem do aparelho após pressão ligeira. Foram realizadas duas sessões de dilatação, inicialmente com balão trough-the-scope de 18 mm e posteriormente com balão pneumático de 30 mm. Os sintomas persistiram e, por esse motivo, foi decidido uma abordagem em dois tempos: primeiro promover a erosão intragástrica da banda para depois a seccionar e remover intraluminalmente. Nesse sentido, foi colocada uma prótese metálica esofágica parcialmente coberta, Luso-Cor® 30/20/30 × 240 mm. O segmento proximal da prótese com 30 mm de diâmetro foi colocado no esófago e o bordo distal da prótese ficou no antro pré-pilórico. No entanto, duas semanas depois, a doente queixou-se de vómitos e enfartamento precoce. O estudo radiográfico com contraste revelou migração distal da prótese, com deslocamento do segmento proximal para o corpo gástrico remanescente. A prótese foi removida endoscopicamente sem dificuldade e, na região da estenose, foi observado o anel de silicone parcialmente erosionado para o lúmen gástrico. Após remoção da prótese a doente evoluiu favoravelmente, sem novos sintomas, e, por esse motivo, foi decido seguimento sem novas intervenções. A endoscopia de seguimento, realizada cinco meses após, demonstrou reepitelização completa do anel parcialmente erosionado. A doente permanece assintomática após três anos de seguimento e voltou a ganhar peso (peso atual 76 kg, IMC 31,2 kg/m2). A eficácia da resolução endoscópica de estenoses relacionadas com anel de silicone no sleeve gástrico já foi relatada. Pequenas séries de casos utilizaram múltiplas sessões de dilatação com balão pneumático ou colocação de próteses plásticas ou metálicas cobertas para promover erosão intragástrica do anel e sua remoção. Acreditamos que a pressão mural exercida pela prótese Luso-Cor®, no curto tempo em que permaneceu in situ, foi suficiente para aliviar a obstrução, realinhando o seu diâmetro com o restante tubo gástrico. Através do relato desta entidade clínica rara, esperamos contribuir para o conhecimento das próteses metálicas específicas para o manejo destes doentes.

Physical Activity before and After Bariatric Surgery.

Lifestyle changes including reduced calorie intake and increased physical activity (PA) improve the prognosis associated with bariatric surgery (BS) and metabolic indices. Early implementation of exercise leads to improved physical performance, better glycemic control and lipid profile, reduces the risks associated with anesthesia, and accelerates recovery from surgery. Undertaking systematic exercise after BS is associated with a better quality of life, improves insulin sensitivity, results in additional weight loss, reduces adverse effects on bone mass, and results in better body composition. The aim of this review was to summarize recommendations for physical activity in patients undergoing BS and to highlight the key role of physical activity in this patient group.

Clinical outcomes of bariatric surgery in patients with obesity and idiopathic intracranial hypertension.

INTRODUCTION: Obesity is a major risk factor for idiopathic intracranial hypertension (IIH). Effective therapeutics for preventing disease progression and alleviating symptoms are limited. This study aims to examine the effects of bariatric surgery on clinical outcomes of IIH. METHODS: We retrospectively collected data from the medical record of 97 patients with obesity and an existing diagnosis of IIH who underwent primary bariatric surgery at the Cleveland Clinic health system in the USA between 2005 and 2023. Pre- and postoperative data on presence of symptoms and clinical markers of IIH (headaches, visual field defects, papilledema, visual symptoms), intracranial pressure, and usage of IIH medications were compared. RESULTS: A total of 97 patients (98% female, median age 46.7 years, median BMI 48.3 kg/m2) with IIH who underwent bariatric surgery including Roux-en-Y gastric bypass (n = 66, 68%), sleeve gastrectomy (n = 27, 27.8%), and gastric banding (n = 4, 4.1%) were analyzed. In a median follow-up time of 3.0 years, the median total weight loss was 24% (interquartile range, 13-33%). There was a significant improvement in headache, papilledema, visual field deficits, and visual symptoms after bariatric surgery. The mean lumbar opening pressure before and after bariatric surgery was 34.8 ± 8.2 cm CSF and 24.2 ± 7.6 cm CSF, respectively, with a mean reduction of 10.7 cm CSF (95% confidence interval, 4.7 to 16.6), p = 0.003. The dosage of acetazolamide and topiramate, as well as the number of medications taken for IIH, decreased significantly after bariatric surgery (p < 0.001). CONCLUSION: For patients who have obesity, bariatric surgery is a viable treatment modality for alleviation or improvement of symptoms of IIH.

Evolution of treated obstructive sleep apneas syndrome after bariatric surgery: an observational retrospective study.

BACKGROUND: The resolution of obstructive sleep apneas syndrome (OSAS) following bariatric surgery appears to be promising for the majority of patients although this resolution does not necessarily exhibit a linear correlation with weight loss. Previous small-scale studies have pinpointed a younger age and preoperative weight under 100kg as predictive factors of OSAS improvement OBJECTIVES: The primary objective was to evaluate the evolution of OSAS in patients treated with continuous positive airway pressure (CPAP). Additionally, we tried to identify potential predictive factors for OSAS improvement postsurgery. SETTING: Brest Hospital, France, University Hospital. METHODS: In this retrospective, observational study we analyzed a cohort of 44 patients who underwent bariatric surgery, between January 2015 and December 2021. Each patient underwent respiratory polygraphy (RP) or polysomnography (PSG) before and after the surgical procedure. We collected CPAP data (including effective pressure and adherence) before and during the 6 months following the intervention. RESULTS: Within the study population, 68.18% of patients exhibited improved OSAS, as defined as an apnea-hypopnea index of less than 15 per hour. A higher mean oxygen saturation prior to surgery emerged as the sole predictive factor for OSAS improvement. CPAP adherence and therapeutic pressure value, 2 rarely studied parameters, did not show significant difference between improved and nonimproved patients. CONCLUSIONS: The rate of OSAS resolution after surgery is 68.18%, with only a higher mean oxygen saturation before surgery identified as a predictive factor for OSAS resolution.

1- and 2-year outcomes and predictors of weight loss after gastric sleeve to Roux-en-Y gastric bypass conversion: a retrospective cohort study.

BACKGROUND: Sleeve gastrectomy to Roux-en-Y bypass conversion is a commonly performed procedure, yet data are limited on outcomes and their predictors. The purpose of this study is to characterize the long-term outcomes of patients after sleeve-to-bypass conversion and identify predictors of post-conversion outcomes. METHODS: We performed a retrospective cohort study of patients who underwent sleeve-to-bypass conversion for obesity across four hospitals from 06/2017 to 04/2023. Predictors of the below-average percent excess weight loss (%EWL; relative to pre-conversion weight) at 1 and 2 years following conversion were identified using multivariate logistic regression models adjusting for comorbidities, demographics, and neighborhood socioeconomic status. RESULTS: 150 Patients undergoing sleeve-to-bypass conversion were identified. 99 had 1-year data and 63 had 2-year data. Mean %EWL at 1- and 2-years following conversion were 40.2% and 37.4%, respectively. EWL > 40% after sleeve gastrectomy was an independent predictor of the below-average %EWL 1-year post-conversion (OR 10.0, 95% CI 2.2-63.0, p < 0.01), and BMI > 40 kg/m2 at the time of conversion was an independent predictor of both 1- and 2-year below-average %EWL post-conversion (p = 0.01 and 0.05, respectively). Insignificant predictors of the below-average %EWL after conversion included: weight regain after sleeve, time between sleeve and conversion, alimentary limb length, and any bariatric surgery prior to sleeve gastrectomy. CONCLUSION: Patients should be counseled that the typical expected %EWL for sleeve-to-bypass conversion is less than the 50% EWL benchmark of success for index bariatric operations. The main predictors of a suboptimal conversion outcome are > 40% EWL after sleeve or > 40 BMI kg/m2 at the time of conversion. Most variables in our analysis were not predictors of post-conversion %EWL, including weight regain between sleeve and conversion, alimentary limb length, and time interval between procedures, which suggests that these factors should not play a large role when considering sleeve-to-bypass conversion.

Proficiency in bariatric surgery may shorten the learning curve for minimally-invasive D2 gastrectomy.

INTRODUCTION: Evidence from Asian studies suggests that minimally-invasive gastrectomy achieves equivalent oncological but improved perioperative outcomes compared to open surgery. Oncological gastric resections are less frequent in European countries. Index procedures may play a role for the learning curve of minimally-invasive gastrectomy. The aim of our study was to evaluate if skills acquired in bariatric surgery allow a safe and oncologically adequate implementation of minimally-invasive gastrectomy in a cohort of european patients. METHODS: In this single-center retrospective study, all patients who received primary bariatric surgery between January 2015 and December 2018 and minimally-invasive surgery for gastric cancer treated from June 2019 to January 2023 were evaluated. Primary endpoints were operation time, lymph node yield and lymph node fractions. Secondary endpoints included postoperative complications and oncological outcomes. RESULTS: Learning curves for two surgeons with 350 bariatric procedures and 44 minimally-invasive gastrectomies were analyzed. For bariatric surgery, the mean operation time decreased from initially 82 ± 27 to 45 ± 21 min and 118 ± 28 to 81 ± 36 min for sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), while the complication rate remained within the international benchmark. For laparoscopic gastrectomy (n = 30), operation times decreased but then remained stable over time. Operation times for the robotic platform were longer (302 ± 60 vs. 390 ± 48 min; p < 0.001) with the learning curve remaining incomplete after 14 procedures. R0 status was achieved in 95.5% of patients; the mean number of lymph nodes retrieved was 37 ± 14 with no differences between the groups. Complete mesogastric excision was more frequently achieved during the later laparoscopic cases whereas it occurred earlier for the robotic group (p = 0.004). Perioperative morbidity was comparable to the European benchmark. Textbook outcome was achieved in 54.4% of the cases. CONCLUSION: In summary, we could demonstrate a successful skill transfer from bariatric surgery to minimally-invasive laparoscopic oncological gastric surgery enabling safe and oncologically adequate minimally-invasive D2 gastrectomy in a central European patient collective.

One anastomosis gastric bypass in a patient with situs inversus totalis and severe obesity.

INTRODUCTION: Obesity is a widespread health concern, and bariatric surgery has shown promise as an effective treatment for addressing this issue. The increasing global prevalence of obesity has led to a rise in the occurrence of obesity alongside rare conditions such as situs inversus totalis (SIT). One of the most effective bariatric surgeries, one-anastomosis gastric bypass (OAGB), has gained popularity in recent years. MATERIALS AND SURGICAL TECHNIQUE: We report a successful case of OAGB in a patient with a body mass index (BMI) of 51.48 kg/m2 and SIT. DISCUSSION: It is worth noting that in skilled hands, OAGB can be both effective and safe for patients with anatomical abnormalities like SIT.

The effect of laparoscopic vertical sleeve gastrectomy and laparoscopic roux-en-Y gastric bypass on gastroesophageal reflux disease: An updated meta-analysis and systematic review of 5-year post-operative data from randomized controlled trials.

BACKGROUND: To evaluate 5-year effect of laparoscopic vertical sleeve gastrectomy (LVSG) versus laparoscopic roux-en-Y gastric bypass (LRYGB) on gastroesophageal reflux disease (GERD) solely based on randomized controlled trials (RCTs). METHODS: A systematic review and meta-analysis of 5-year postoperative GERD data comparing LVSG and LRYGB in adults were undertaken. Electronic databases were searched from January 2015 to March 2024 for publications meeting inclusion criteria. The Hartung-Knapp-Sidik-Jonkman random effects model was applied to estimate pooled odds ratio where meta-analysis was possible. Bias and certainty of evidence were assessed using the Cochrane Risk of Bias Tool 2 and GRADE. RESULTS: Five RCTs were analysed (LVSG n = 554, LRYGB n = 539). LVSG was associated with increased adverse GERD outcomes compared to LRYGB at 5 years. The odds for revisional surgery to treat GERD in LVSG patients were 11 times higher compared to LRYGB (OR 11.47, 95% CI 1.83 to 71.69; p = 0.02; I2 = 0% High level of certainty). Similarly pharmacological management for increasing GERD was significantly more frequent in LVSG patients compared to LRYGB (OR 3.89, 95% CI 2.31 to 6.55; p ≤ 0.01; I2 = 0% Moderate level of certainty). Overall, LVSG was associated with significantly more interventions (both medical and surgical) for either worsening GERD and/or development of de novo GERD compared to LRYGB (OR 5.98, 95% CI 3.48 to 10.29; p ≤ 0.01; I2 = 0%) Moderate level of certainty). CONCLUSIONS: The development and worsening of GERD symptoms are frequently associated with LVSG compared to LRYGB at 5 years postoperatively requiring either initiation or increase of pharmacotherapy or failing that revisional bariatric surgery. Appropriate patient/surgical selection is crucial to reduce these postoperative risks of GERD.

Ultrasound-Guided Transversus Abdominis Plane Block as an Effective Path to Reduce Opioid Consumption After Laparoscopic Bariatric Surgery: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Effective postoperative pain management is essential to the patient's recovery. The use of opioids as the primary line of pain treatment has been known to increase rates of length of stay, pulmonary complications, paralytic ileus, and nausea and vomiting. Therefore, guidelines strongly recommend alternative paths to reduce opioid consumption through multimodal analgesia, and the transversus abdominis plane block(USG-TAP) has been considered to be one of these optimistic alternatives. A comprehensive systematic search was conducted in four databases until April 2024. We only considered for this analysis randomized controlled trials that assessed the USG-TAP as part of multimodal anesthesia in patients undergoing laparoscopic bariatric surgery. Eleven studies comprising 789 patients were included in the meta-analysis. Our results showed a significant decrease in opioid consumption after the first 24 h of surgery (MD - 32.02 mg; 95% IC - 51.33, - 12.71; p < 0.01) and fewer patients required extra-dose of opioid (OR 0.20; 95% IC 0.07, 0.62; p < 0.01). The pain score showed to be also improved with the TAP block (MD - 0.69; 95% IC - 1.32, - 0.07; p = 0.03). No difference concerning time to deambulate, nausea and vomiting, and time of surgery was observed among the studies. This study reinforces the benefits of the use of USG-TAP block as part of multimodal analgesia in patients undergoing laparoscopic bariatric surgery.

Prevalence of dumping and hypoglycaemia symptoms after bariatric surgery: A questionnaire-based cross-sectional study.

Dumping and post-bariatric hypoglycaemia (PBH) are side effects that occur after bariatric surgery. The aim of this study was to estimate the prevalence of dumping and PBH symptoms before Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) at 6 months, 1 year, 2 years and 5 years after surgery in a Swedish population. A cross-sectional single-centre study was performed at Lindesberg Hospital, Region Örebro County, Sweden, between 2020 and 2023. The Swedish version of the Dumping Severity Scale (DSS-Swe) questionnaire, which includes eight items regarding dumping symptoms and six items regarding hypoglycaemia symptoms, was used. A total of 742 DSS-Swe questionnaires were included. The average age at surgery was 42.0 years (standard deviation [SD] = 11.9), and the average body mass index was 41.8 kg/m2 (SD = 5.9). The surgical methods consisted of RYGB (66.3%) and SG (33.7%). The proportion of RYGB patients with highly suspected dumping increased from 4.9% before surgery to 26.3% (adjusted odds ratio [OR] = 7.35, 95% confidence interval [CI] = 3.08-17.52) at the 5-year follow-up. PBH symptoms increased from 1.4% before surgery to 19.3% at the 5-year follow-up (adjusted OR = 17.88, 95% CI = 4.07-78.54). For SG patients, no significant increase in dumping or PBH symptoms was observed. In patients with persistent type 2 diabetes (T2D), there were no cases of highly suspected hypoglycaemia following RYGB or SG. Symptoms of dumping and PBH were common after RYGB, while no clear increase was observed after SG. Persistent T2D seems to be a protective factor against PBH symptoms.

Bone loss after bariatric surgery is observed mainly in the hip trabecular compartment and after hypoabsorptive techniques.

We evaluated the impact of bariatric surgery on bone mineral density (BMD) and microarchitecture over one year using dual-energy X-ray absorptiometry (DXA), the trabecular bone score (TBS), and 3D-DXA to assess changes after different surgical techniques. This prospective, single-center study of 153 patients with severe obesity contrasts the effects on bone health of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and duodenal switch/single anastomosis duodeno-ileostomy with sleeve gastrectomy (DS/SADIS). To our knowledge, this is the first study to evaluate patients undergoing DS/SADIS and to incorporate 3D-DXA analysis in the assessment of bone loss. Patients were 81 % female with a mean age of 50 ±â€¯9 years. Fifty-four per cent underwent SG; 16 %, RYGB; and 30 %, DS/SADIS. Our findings revealed a significant decrease in areal BMD at the LS (-3.49 ±â€¯5.44 %), FN (-5.24 ±â€¯5.86 %), and TH (-8.06 ±â€¯5.14 %) one year after bariatric surgery. Bone microarchitecture at the LS assessed by TBS was degraded in 30 % of patients. Proximal femur 3D-DXA analysis showed that surgery-induced bone loss predominantly affects the trabecular compartment (Trabecular volumetric (v) BMD: -8.00 ±â€¯6.57 %) rather than the cortical compartment (Cortical vBMD: -1.37 ±â€¯2.79 %). These results suggest hypoabsorptive and mixed techniques (DS/SADIS and RYGB) were associated with greater BMD loss and deterioration of microarchitecture than restrictive techniques (SG). The primary determinants of bone density and impairment of microarchitecture were the extent of weight loss and the type of surgical procedure. Despite overall bone loss, Z-score assessments indicated that post-surgical bone status remained within or above the average ranges compared to a healthy population, except for TH following DS/SADIS. In conclusion, our research shows differences in the impact of bariatric surgery techniques on bone density and microarchitecture, emphasizing the need for careful postoperative monitoring of bone health, particularly in patients undergoing hypoabsorptive and mixed procedures.

Perceptions of Adult Obesity Education: A Pilot Study.

Objectives: This pilot research study, conducted at a large academic healthcare facility, used mixed methodology to (1) administer a survey to a group of primary care trainees and faculty and (2) conduct key informant interviews with the program directors, or their delegates of these primary care training programs, so as to gain insight into respondents' perceptions about their training on adult obesity. To maintain confidentiality of the key informants, they were defined as "Administrators." Faculty and trainees were from family medicine and internal medicine residency programs, as well as family nurse practitioner and physician assistant training programs. Methods: This study used a quantitative survey and four qualitative key informant (Administrator) interviews. Descriptive statistics, χ2, or Fisher exact tests were used to analyze select survey responses. Administrator interviews were analyzed with thematic analysis. Results: Survey respondents (n = 75) included primary care trainees (n=34), faculty (n=30), other (n=2), did not answer (n=9). Surveys indicated that additional training is needed for bariatric surgery, weight loss medications, and clinical nutrition. The three highest ranked topics in the surveys on adult obesity were basic nutrition, behavioral weight management, and a rotation on adult obesity. Most agreed on the need for interprofessional collaboration, a centralized obesity treatment center, and an introductory obesity course. Key themes from the four Administrator interviews revealed the need: for more training; to build upon current curriculum; use innovative technology; fiscal challenges; and time management. Conclusions: Both faculty and trainees perceive that academic and clinical training on adult obesity is inadequate, and that trainees need more education on such topics as nutrition, physical activity, behavioral health, antiobesity medications, and bariatric surgery. Competency to treat varied by topic. It also showed that more interprofessional collaboration and a centralized obesity treatment center are needed. Recommendations included integrating modular units about obesity into already established primary care training programs and providing additional resources.
