Introduction: Wernicke’s encephalopathy (WE) is a neuropsychiatric complication of bariatric surgery (BS) due to vitamin B1 deficiency, whose early presentation is infrequent and underdiagnosed. Aim: To present a case of early WE after laparoscopic gastric bypass (LGB) and discuss its diagnosis, complications and treatment. Materials and Methods: A 23-year-old obese woman on whom a LGB was performed, from the fourth postoperative day presented with nausea, cough, drooling, abdominal discomfort, and irritability. The imaging and endoscopic study ruled out surgical complications. WE is suspected, so a brain MRI is taken, resulting in normal. However, after a thiamine load the symptoms resolve. Results and Discussion: Vomiting, surgery, and the physiologically limited reserve of B1 determined an early onset of WE, which typically occurs between 4 and 12 weeks in BS. Classical symptoms and its imaging findings are present in the minority of patients. WE is a rare but potentially serious complication in BS even with irreversible memory damage. The growing volume of BS has increased its incidence. An adequate supplementation and diagnostic suspicion are key for its prevention and early treatment. [ABSTRACT FROM AUTHOR]

Post-gastric bypass hypoglycemia is characterized by postprandial hypoglycemia with pancreatic islet-cell hypertrophy in patients who have undergone a bariatric surgery and may be prone to hypoglycemia due to NAFLD, obesity, and impaired insulin and glucagon secretion. We present the case of a 44-year-old obese woman with NAFLD who underwent a Roux-en-Y gastric bypass and years later presented with severe hypoglycemia. She was diagnosed with endogenous hyperinsulinemic hypoglycemia and beta-cell hyperplasia. Post-gastric bypass hypoglycemia is a scenario that will be faced more often; therefore, it is important to take it into account for a timely treatment. [ABSTRACT FROM AUTHOR]

Atualmente, a obesidade é um dos principais problemas de saúde pública, sendo considerada uma doença crónica e ao mesmo tempo um fator de risco para o desenvolvimento de outras doenças crónicas, associa-se a um conjunto de alterações metabólicas, nomeadamente a hipertensão arterial e a diabetes mellitus tipo 2. O Bypass gástrico é uma cirurgia muito utilizada por conseguir atingir perdas de 40% do peso inicial, sendo realizada por vídeo-laparoscopia ou por via convencional. Objetivo: Identificar nos diversos estudos científicos evidências que comprovem que no âmbito da cirurgia bariátrica, o bypass gástrico é um método cirúrgico eficaz no combate a doenças metabólicas, nomeadamente a hipertensão arterial e a diabetes mellitus tipo 2. Métodos: Trata-se de um estudo, delineado conforme os procedimentos da revisão sistemática da literatura, orientado pelo protocolo PICO e pela seguinte questão de investigação: “Será o bypass gástrico eficaz no combate a doenças metabólicas, nomeadamente a hipertensão e a diabetes mellitus tipo 2?” Resultados: Relativamente à diabetes mellitus tipo 2 verificou-se uma prevalência que variou de 25% a 86,8%. Já os dados referentes à hipertensão arterial a HTA variou de 12% a 99,5%. Todos os artigos analisados concluíram que o bypass gástrico é um bom método cirúrgico para perda de peso e melhoria da qualidade de vida. Conclusão: Nos casos em que as alterações comportamentais e terapia farmacológica se mostraram ineficazes, a cirurgia bariátrica demonstrou ser uma peçachave no tratamento da diabetes mellitus tipo 2 e hipertensão arterial em indivíduos obesos, podendo mesmo causar a sua remissão completa. O bypass gástrico mostrou ser um bom método cirúrgico, apresentando resultados a nível de benefício/risco, tendo um elevado grau de eficácia e baixas complicações. Embora eficaz implica alguns riscos sendo necessário um estudo personalizado para cada doente de modo a calcular o benefício/risco individualmente.

Background: Candy cane syndrome (CCS) is a rare complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). It occurs due to redundancy in the blind loop at the gastro-jejunal anastomosis., Objective: To evaluate the type of symptoms, anatomic and functional findings, and outcome after treatment., Material and Methods: A prospective case series study was conducted between 2010 and 2022, including symptomatic patients with CCS after LRYGB. Symptoms were correlated with anatomic and functional findings. Big gastric pouch was defined if its size was >5 cm, and a long candy cane loop was diagnosed if its length was >5 cm. Due to failure of medical treatment, revision surgery (RS) was indicated for resection of the elongated blind jejunal loop, resizing the redundant gastric pouch and repairing the hiatal hernia repair (HH) when necessary., Results: The study included 23 patients, with a mean age of 49 ± 11 years. Twenty-one patients underwent primary LRYGB, and 2 were converted to this technique after sleeve gastrectomy (SG). The mean time from LRYGB to symptom onset was 7.6 ± 4.3 years. Pain and reflux symptoms were the most frequent, with no differences between patients with or without HH (P < .05). CCS coexisted with a large gastric pouch in 56.5% and HH in 52.2% of cases. A defective lower esophageal sphincter, abnormal esophageal motility, and pathological acid reflux test were observed. After surgery, improvement was observed in 86.9%., Conclusion: CCS can lead to gastrointestinal symptoms following LRYGB, regardless of the presence of HH. Complete examinations are crucial for diagnosis and to determine the surgical intervention, which is the best option for treatment., Competing Interests: Declaration of competing interest All patients gave their written informed consent to be included in this study, in accordance with the Institutional and Ministerial Committees., (Copyright © 2024 AEC.

México es el primer lugar a nivel mundial en obesidad; la Diabetes tipo 2 se encuentra asociada hasta en 90%. Este estudio observacional ambispectivo del 2009 al 2015, compara las tasas de remisión de diabetes tipo 2 en pacientes con IMC >35 kg/m² operados de Bypass Gástrico Laparoscópico (BPGL) vs Gastrectomía Vertical en Manga Laparoscópica (GVML) monitorizando la normalización de los niveles de glucosa plasmática, disminución del porecentaje de HbA1C y cese en el uso de antidiabéticos por lo menos un año, siendo ese su objtetivo. Se analizaron los expedientes clínicos de los pacientes operados de BPGL y GVML con obesidad mórbida y diabetes tipo 2 en el periodo de enero del 2009 a junio del 2015, registrando en una base de datos las variables medibles de cada paciente. Se utilizó una tabla de ANOVA y la prueba t de Student mediante programa de análisis de datos SPSS®. Posterior a la cirugía se registraron cifras de glucosa en ayuno <100 mg/dl desde los primeros tres meses en la mayoría de los pacientes. Después de 12 meses de seguimiento los niveles de glucosa descendieron de 152.16 ± 65.3 mg/dl a 88.16 ± 14.05 mg/dl (p< 0.001), el porcentaje de HbA1C bajó de 7.4 ± 1.4 a 5.3 ± 0.8 (p <0.001), cuatro pacientes continuaron con algún tipo de medicamento, dos con insulina y dos con hipoglucemiantes orales. Existió una remisión de la diabetes tipo 2 en 20 pacientes (80%). En los pacientes con obesidad mórbida y diabetes tipo 2 tratados en el Hospital Central Militar, la GVML y el BPGL han demostrado seguridad y efectividad en la remisión de diabetes tipo 2 a mediano plazo. Sin diferencia significativa entre ambos. [ABSTRACT FROM AUTHOR]

The purpose of our study was to compare the postoperative quality of life, weight loss and improvement of co-morbidities in laparoscopic Roux-en-Y gastric bypass (LRYGB) and Laparoscopic sleeve gastrectomy (LSG) patients one year after surgery. Materials and Method: Match pair analysis of the prospectively collected database of the 23 gastric bypass and 37 gastric sleeve patients operated on in our hospital was performed. Weight loss, quality of life and improvement of co-morbidities were measured at one year after surgery. The quality of life parameters were measured with two standard questionnaires: Gastrointestinal Quality of Life Index (GIQLI) and Bariatric Analysis and Reporting Outcomes System (BAROS). Results: After one year of follow-up the mean BMI was 29.9 ± 4 kg/m2 in LRYGB and 31.3 ± 5 kg/m2 in LSG. The percent excess BMI Loss (%EBMIL) was 74.5 ± 19.2% (LRYGB) and 67.5 ± 23.1% (LSG). A success score in BAROS was obtained in 87% (LRYGB) and 83.8% (LSG). The mean GIQLI score was 108.3 ± 19 (LRYGB) and 109.8 ± 18.3 (LSG). These results did not differ significantly. Remission of co-morbidities was similar in the BGYRL and LSG groups (50 vs 53.8%). Conclusions: Both types of surgery are effective in quality of life, co-morbidities and weight loss after one year of follow-up. The LRYGB produced better results in %EBMIL and BAROS, and the LSG produced better results in GIQLI (overall and digestive symptoms). These results did not differ significantly.

Introduction: Due to its efficacy in the treatment of morbid obesity, roux-en-y gastric bypass (RYGB) continues to be a frequently performed intervention. However, a small group of patients may develop nutritional and metabolic complications that cannot be controlled with optimal medical treatment. In these cases, it may be necessary to reestablish the continuity of the gastrointestinal tract by reversing the RYGB (R-RYGB). Aim: To present the indications and results obtained in a series of patients who underwent to R-RYGB. Materials and Method: Identification and retrospective evaluation of all patients who underwent consecutive R-RYGB in our institution. Demographic and anthropometric characteristics of the original surgery and at the time of the reversal were recorded. Complications were classified according to Clavien-Dindo classification. Results: Seven patients were identified in whom an R-RYGB was performed. In 2 cases the reversal was due to short bowel syndrome, in 3 cases due to severe hypoglycemia refractory to medical treatment and in 2 cases due to chronic diarrhea. The median age at the time of the reversal was 55 years. The median time from primary surgery to reversal was 77 months. The median hospital stay was 6 days. There were no Clavien-Dindo complications ≥ III. The R-RYGB was able to reverse nutritional and metabolic complications in all cases. Conclusion: Restoring the continuity of the gastrointestinal tract allows control of nutritional and metabolic complications. [ABSTRACT FROM AUTHOR]

Associated with the obesity epidemic and the growing number of bariatric surgery procedures being performed worldwide, the incidence of reported complications has increased as well. Among these, the postprandial hyperinsulinemic hypoglycemia (PHH) warrants further attention. This condition is not entirelly understood and is probably underdiagnosed. The PHH is characterized by hypoglycemic symptoms occurring after a meal accompanied by a low plasma glucose value, typically preceded by a high rise in both glucose and insulin concentrations. Patients with PHH have shown increased glucose variability with a rapid increase in glucose absorption into the systemic circulation and an increase in glucose disappearance, with glucose values reaching both the hyperglycemic and hypoglycemic areas. It should be suspected in patients with postprandial adrenergic or neuroglycopenic symptoms after bariatric surgery1. It was considered most commonly associated with Roux-en Y gastric bypass (RYGB), although it was also described after biliopancreatic diversion (BPD), BPD with duodenal switch2, sleeve gastrectomy, and other surgical procedures which compromises the pylorus and the gastric emptying3. It has not been observed after adjustable gastric banding, an intervention that does not alter the gastrointestinal anatomy4-5.

One of the recent advances in bariatric surgery is the use of magnetic devices. This research paper describes magnetic liver retraction in morbidly obese patients during bariatric surgery. A descriptive, prospective and observational study was carried out, analyzing 100 patients in whom magnetic retraction was used. Mean and SD body mass index was 46.1 ± 5.09 kg/m 2 . The magnetic system was successfully used for liver retraction in 95% of cases; in only 5% of cases was its use not possible due to hepatomegaly and severe hepatic steatosis. According to the results, magnetic liver retraction can be safe and used in bariatric surgery, regardless of body mass index and with a low percentage of complications., (Copyright © 2024.

Introduction: Background: bariatric surgery is an effective therapeutic alternative for morbid obesity as it achieves significant weight loss, maintained over time, as well as the resolution of comorbidities and a decreased cardiovascular risk. Material and methods: a retrospective study that included all patients consecutively undergoing laparoscopic gastric bypass in our center for 10 years, in which weight loss, comorbidities, and cardiovascular risk factors were studied prior to surgery and at the end of follow-up. Results: 303 patients, 221 women and 82 men, with a mean age of 42.3 ± 10.0 years and BMI of 48.2 ± 6.0 kg/m2 were included. Of these, 96.7 % were followed for 5.7 ± 2.6 years on average. The resolution of comorbidities at the end of follow-up included: 53.4 % for high blood pressure, 70.2 % for diabetes mellitus type 2, 83.9 % for dyslipemia, and 71.4 % for apnea-hypopnea sleep syndrome. The cardiovascular risk estimated by the REGICOR algorithm before and at the end of follow-up was 3.2 ± 2.6 and 2.2 ± 1.7, respectively, with a decrease by 32.2 %, like all the parameters included in its calculation except for HDL-cholesterol levels, which did not experience significant variations. The body mass index and percentage of overweight lost at 2 years and at the end of the follow-up was 30.7 ± 5.2 kg/m2 vs. 33.0 ± 6.1 kg/m2 and 66.4 ± 17.1 % vs. 57.9 ± 19.5 %, respectively. Conclusion: gastric bypass is an effective method for the resolution of comorbidities and reduction of cardiovascular risk, but it is very important to monitor as many patients as possible, and to report on the long-term results, to determine the real effectiveness of these procedures.

Introduction: Introduction: the Roux-en-Y gastric bypass (RYGB) is considered to be an efficient treatment of obesity. There is an improvement in the dietary intake in the immediate postoperative period, but after the first year there is a tendency to return to the old pre-surgery habits. The objective of the present study was to compare the dietary intake of women in the late postoperative period after RYGB with the recommendations of the specific bariatric food pyramid. Methodology: the whole population of patients submitted to RYGB being accompanied by two out-patients departments of the Complexo Hospital de Clínicas of Universidade Federal do Paraná in the period from March to September 2017 were considered, selecting only those who conformed to the inclusion criteria. The analyses carried out were: the hospital records, anthropometric evaluation, basal metabolic rate by indirect calorimetry, food consumption and questionnaires concerning physical activity, food intolerance and the dumping syndrome. The food consumption was separated into food groups in order to compare with the specific pyramid. Descriptive analyses were used to characterize the sample. Results: it can be seen that the percent of macronutrients in relation to the total energy value (TEV) was within the values established by the recommended dietary allowances (RDA), although with respect to fiber, 68% of the participants showed a consumption below the adequate intake (AI). Inadequacy was observed for practically all the components when comparing the number of portions per food group of the bariatric pyramid, with the exception of the protein group. Conclusion: after RYGB, the dietary consumption was compromised in quantity and quality. In addition, in the late postoperative period, women tended to choose high calorie dense foods poor in fiber, a fact that is aggravated by the presence of food intolerances. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: among the surgical techniques that promote greater weight loss are Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). These procedures generate changes in muscle mass (MM) and fat mass (FM). Objective: the aim of this study was to determine changes in body composition in patients undergoing RYGB and SG in a period of one-year after surgery. Methods: a cross-sectional retrospective study was conducted in three clinical centers of bariatric surgery in the Metropolitan Region, Chile. Information on MM and FM was obtained through bioimpedance analysis of 96 women and 32 men, operated between 2013 and 2017. Results: RYGB operated subjects presented higher MM content preoperatively and at the end of the first year compared to SG. In the first six months, the loss for MM, FM and % total fat (%FM) was similar in both techniques. Men with RYGB present greater loss of MM and FM in the first trimester post-surgery than those who submitted to SG (p = 0.0453). Subjects submitted to RYGB presented higher weight and body mass index (BMI) in the preoperative (p = 0.0109); the BMI at the end was similar in both surgical techniques (p = 0.6936). The lost kilos of MM were greater in the subjects submitted to RYGB (p = 0.0042), however, the % loss of MM exceeds the recommended (up to 22%) in both techniques. Conclusion: the nutritional approach is necessary to increase protein intake pre- and post-surgery as well as physical activity in order to preserve this compartment. [ABSTRACT FROM AUTHOR]

The gold standard for bariatric surgery is the laparoscopic gastric bypass, which consists in forming a small gastric pouch and a Roux-en-Y anastomosis. We present the case of a 41-year-old female who underwent a laparoscopic gastric bypass 8 years prior to her admission to the emergency room, where she arrived complaining of severe and colicky epigastric abdominal pain. The abdominal computed tomography showed a jejuno-jejunal intussusception, for which the patient underwent urgent exploratory laparotomy with intussusception reduction. Intestinal intussusception is a possible postoperative complication of a Roux-en-Y gastric bypass., (Copyright: © 2023 Permanyer.)

Introduction. Bariatric Analysis and Reporting Outcome System (BAROS) has been validated as the best comprehensive and objective evaluation system to assess the benefits of bariatric surgery. It considers different variables such as percentage of excess weight loss (% EWL), resolution and / or improvement of comorbidities, and postoperative quality of life. Complications of the procedure or surgical reoperations are also taken into account. Material and Methods. The objective of the study was to create a comparison between Roux on Y Gastric Bypass (RYGB) and Gastric Sleeve (GS) to assess which of the two surgical techniques has the best outcomes according to the BAROS model. Of the 282 patients operated at San Javier Hospital between January 2011 and December 2016, only 66 agreed to consent to participate in the study. Of these patients, 37 were female and 29 male who were followed up at 6 and 12 months after surgery, 43 patients underwent RYGB and 23 GS. Results. The pre-surgical average body mass index (BMI) was 38.9 kg / m2. The average age was 38 years and the %EWL was 69.5 for RYGB and 109.5 for GS. The majority of patients had improvement of their comorbidities. The quality of life according to the Moorehead-Ardelt questionnaire showed improvement in all patients. The evaluation with the BAROS score in the RYGB group was excellent in 93% and very good in 7% of patients. In the GS group, 87% obtained excellent results, 9% very good and 4% good. Discussion. Both surgical approaches yielded excellent results of weight loss control in obese patients with associated comorbidities as well as improving their quality of life. These results demonstrate that BAROS is simple and quick evaluation tool for bariatric patients after surgery. [ABSTRACT FROM AUTHOR]

Introduction: bariatric surgery does not benefit all patients. Identifying severely obese patients who will succeed after bariatric surgery remains a challenge for the transdiciplinary team. The objective of this retrospective study was to analyze preoperative dietary factors that could predict a successful weight loss after bariatric surgery.Methods: the retrospective study included patients undergoing laparoscopic Roux-en-Y gastric bypass surgery as a procedure for severe obesity (n = 84). Patient demographics, comorbidities, dietary factors, and weight loss results were extracted from the electronic medical record.Results: type 2 diabetes mellitus (DM2) was associated with suboptimal weight loss after laparoscopic Roux-en-Y gastric bypass surgery.Conclusions: although bariatric surgery continues being the most effective treatment for patients with severe obesity, developing strategies to improve and maintain weight loss, especially in patients with DM2, is fundamental. Assessing the dietary characteristics of candidates for bariatric surgery is crucial. [ABSTRACT FROM AUTHOR]

Background and Objectives: Resistin was originally suggested to be a potential mediator of obesity-related insulin resistance in rodents. However, in humans, the role of resistin in obesity and insulin resistance has not yet been demonstrated. The present study investigates whether there are differences in resistin levels between patients with morbid obesity and lean subjects, and analyzes changes in resistin levels after significant weight loss secondary to bariatric surgery.Methods: Sixty-eight patients with morbid obesity (body mass index [BMI] ≥ 40 kg/m2) and 31 lean subjects (BMI < 25 kg/m2) were selected. The study variables were: weight, height, BMI, waist-hip ratio (WHR), fat mass, family history of cardiovascular disease (CVD), type 2 diabetes mellitus (DM), hypertension, dyslipidemia, smoking, glucose, glycated hemoglobin (HbA1c), insulin, high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), adiponectin and resistin. Homoeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI) were calculated. The obese patients underwent gastric bypass surgery, and the above mentioned variables were reassessed after 12 months and major weight loss.Results: There were no significant differences in resistin levels between morbidly obese patients and healthy subjects of normal weight, or between obese patients before and after weight loss. Resistin levels in morbidly obese patients were not correlated to adiposity anthropometric measures, insulin, glucose, HOMA, QUICKI, hsCRP, IL-6 or adiponectin. In the morbid obesity group, after one year of weight loss, the only study parameter correlated to resistin levels was IL-6.Conclusion: Our results do not support a relationship among resistin levels, obesity and insulin resistance in humans.

The persistence of obesity favors the failure of the Fundoplication (FP) in the treatment of Gastroesophageal Reflux (GER). However, the weight loss obtained with the performance of a Gastric Bypass (GBP) allows a good resolution of symptoms, without increasing the incidence of postoperative complications. All of this leads us to consider that while FP is the indication in patients with BMI < 30, in those patients with BMI > 35, GBP appears to be the procedure of choice. But there is still no position in the case of patients with a BMI between 30 and 35, although we must take into account that an increase in GER recurrence has been described after FP in patients with a BMI > 30. Although Sleeve Gastrectomy (SG) is one of the most frequently used bariatric procedures in recent years, its association with a high rate of postoperative GER has led several authors to propose its performance associated with an anti-reflux procedure in patients with GER symptoms. Likewise, if the existence of an Hiatal Hernia is verified, it must be treated by hiatoplasty, both during the performance of a GBP and a SG. This simultaneous treatment is not associated with an increase in complications., (Copyright © 2023 AEC. Published by Elsevier España, S.L.U. All rights reserved.)

Although it is uncommon, gastroesophageal reflux disease can present after Roux-en-Y gastric bypass, and it is usually related to technical errors. Hiatal hernia, a narrow calibrated gastrojejunostomy and a long gastric pouch are all factors associated with the development of pathologic gastroesophageal reflux. Techniques are available to treat this condition, such as fundoplications with the gastric remnant, gastropexy to the arcuate ligament, teres ligament repair, or sphincter augmentation with the LINX device. Despite the growing number of reports of gastroesophageal reflux after Roux-en-Y gastric bypass, it should be still considered the best surgical option for patients with obesity and a large hiatal hernia or complications secondary to gastroesophageal reflux disease., (Copyright © 2023.

Introduction: the ultimate cause for the increased incidence of gastric ulcer following Roux-en-Y gastric bypass (RYGB) remains unclear. Treatment of HP infection is recommended before surgery in countries with high prevalence such as Spain in other to diminish the risk. However, the current regimens used might not be adequate in view of the high failure rate for HP eradication.Methods: we reviewed 243 patients retrospectively undergoing RYGB and found 111 patients (45%) with HP infection. Therefore, we compared the eradication rate between 2 different regimens.Results: 70 patients received OCA(Omeprazole:20 mg/12h, Clarithromycin 500 mg/12h and Amoxicillin 1 gram/12h for 10 days) while 41 patients received OLA (Omeprazole 20 mg/12 hours, Levofloxacin 500 mg/12hours and Amoxicillin 1 gram/12h for 10 days) for HP eradication. In 56/70 (80%) patients receiving OCA therapy HP was eradicated compared to 37/41 (91%) receiving OLA as first line therapy (p = 0.283). When used as second line therapy, in 13/14 (92%) patients receiving OLA HP was eradicated.Conclusion: clarithromycin resistance remains a matter of concern in this population while OLA seems to be a good alternative therapy for HP eradication, especially when OCA regimen fails.

The aim of the present study was to describe the clinical- nutritional evolution of older women submitted to Roux-en-Y gastric bypass surgery. A concurrent, retrospective study was conducted involving a sample of 16 older women with morbid obesity submitted to Rouxen- Y gastric bypass surgery between 1997 and 2010. Weight, body mass index (BMI), percentage of weight loss (%WL) and percentage of excess weight loss (%EWL) were evaluated three, six and 12 months after surgery. Preoperative comorbidities, postoperative clinical-nutritional manifestations and peri-operative mortality were also investigated. Mean age was 62.02 ± 2.02 years. A progressive reduction was found in mean body weight (116.04 ± 22.99 to 80.96 ± 21.43 Kg) and BMI (47.13 ± 8.19 to 33.42 ± 9.31 Kg/m2), with a consequent %WL of 28.60 ± 8.59% and %EWL of 64.79 ± 3.99% throughout the one-year follow-up period (p < 0.05).
