RESUMO

OBJECTIVE: Compare the weight loss results between long-term procedures up to 5 years, after undergoing MGL and RYGB in Mexican patients with obesity and associated comorbidity. The most common bariatric surgical procedures worldwide are, laparoscopic gastric sleeve (MGL) and laparoscopic Roux-en-Y gastric bypass (RYGB), as a treatment for weight loss and remission of comorbidity associated with obesity; however, they are the long-term weight loss results in the Mexican population are unknown. METHOD: Retrospective, observational cohort of patients with obesity undergoing MGL or RYGB in a private hospital Medica Sur, in Mexico City, in the period from 2013 to 2021. Instrumental variables analysis and standardized mean differences were used to calculate outcomes up to 5 years at 5 follow-up visits (S1-S5), at 7 days, 2 months, 6 months, 10 months and 2-5 years after surgery, to compare results of the groups. RESULTS: 104 patients were included in two groups: 31 (30.09%) with MG and 73 (70.87%) with RYGB. The last follow-up (S5), the MG group recorded a mean EW 9.61 kg, EW% 12.72% and EWL% 73.50%, and the RYGB group EW 10.1 kg, EW% 14.72% and EWL% 70.41%. CONCLUSIONS: No significant difference was found between groups for long-term EW loss (p = 0.082); however, there is a greater decrease in weight loss in RYGB at 6-12 months compared to MGL.


OBJETIVO: Comparar los resultados de pérdida de peso con los procedimientos MGL y BGYRL a largo plazo (hasta 5 años) en pacientes mexicanos con obesidad y comorbilidad asociada. Son dos los procedimientos quirúrgicos bariátricos más frecuentes en todo el mundo: la manga gástrica lapa-roscópica (MGL) y el bypass gástrico en Y de Roux laparoscópico (BGYRL); ambos como tratamiento para pérdida ponderal y remisión de la comorbilidad asociadas a la obesidad. Sin embargo, se desconocen los resultados de pérdida de peso a largo plazo en la población mexicana. MÉTODO: Cohorte retrospectiva, observacional, de pacientes con obesidad sometidos a MGL o BGYRL en el hospital privado Médica Sur, de Ciudad de México, en el período de 2013 a 2021. Se utilizó el análisis de variables instrumentales y diferencias de medias estandarizadas para calcular los desenlaces hasta 5 años posquirúrgicos en cinco consultas de seguimiento (S1-S5) a los 7 días, 2 meses, 6 meses, 10 meses y 2-5 años posquirúrgicos, para comparar los resultados de los grupos. RESULTADOS: Se incluyeron 104 pacientes en dos grupos: 31 (30.09%) con MG y 73 (70.87%) con BGYR. En el último seguimiento (S5), el grupo de MG registró media de EW 9.61 kg, EW% 12.72% y EWL% 73.50%, y el grupo BGYR tuvo EW 10.1 kg, EW% 14.72% y EWL% 70.41%. CONCLUSIONES: No se encontró diferencia significativa entre grupos para pérdida de EW a largo plazo (p = 0.082); sin embargo, hay una mayor disminución de pérdida ponderal en los pacientes con BGYRL a los 6-12 meses en comparación con los tratados con MGL.

RESUMO

The factors determining the reversal of metabolically unhealthy obesity (MUO) to metabolically healthy obesity (MHO) after Roux-en-Y gastric bypass (RYGB) are not completely elucidated. The present study aims to evaluate body adiposity and distribution, through different indices, according to metabolic phenotypes before and 6 months after RYGB, and the relationship between these indices and transition from MUO to MHO. This study reports a prospective longitudinal study on adults with obesity who were evaluated before (T0) and 6 months (T1) after RYGB. Bodyweight, height, waist circumference (WC), BMI, waist-to-height ratio (WHR), total cholesterol (TC), HDL-c, LDL-c, triglycerides, insulin, glucose, HbA1c and HOMA-IR were evaluated. The visceral adiposity index (VAI), the conicity index (CI), the lipid accumulation product (LAP), CUN-BAE and body shape index (ABSI) were calculated. MUO was classified based on insulin resistance. MUO at T0 with transition to MHO at T1 formed the MHO-t group MHO and MUO at both T0 and T1 formed the MHO-m and MUO-m groups, respectively. At T0, 37.3% of the 62 individuals were classified as MHO and 62.7% as MUO. Individuals in the MUO-T0 group had higher blood glucose, HbA1c, HOMA-IR, insulin, TC and LDL-c compared to those in the MHO-T0 group. Both groups showed significant improvement in biochemical and body variables at T1. After RYGB, 89.2% of MUO-T0 became MHO (MHO-t). The MUO-m group presented higher HOMA-IR, insulin and VAI, compared to the MHO-m and MHO-t groups. CI and ABSI at T0 correlated with HOMA-IR at T1 in the MHO-t and MHO-m groups. CI and ABSI, indicators of visceral fat, are promising for predicting post-RYGB metabolic improvement. Additional studies are needed to confirm the sustainability of MUO reversion and its relationship with these indices.

RESUMO

PURPOSE: To evaluate glycemic variability (GV) using continuous glucose monitoring (CGM) in individuals with and without type 2 diabetes mellitus (T2DM) undergoing Roux-en-Y gastric bypass (RYGB). METHODS: This prospective cohort study compared the CGM data of fourteen patients with T2DM (n = 7) and without T2DM (n = 7) undergoing RYGB. After 6 months, these patients were compared to a non-operative control group (n = 7) matched by BMI, sex, and age to the T2DM group. RESULTS: Fourteen patients underwent RYGB, with a mean BMI of 46.9 ± 5.3 kg/m2 and an average age of 47.9 ± 8.9 years; 85% were female. After 6 months post-surgery, the total weight loss (TWL) was 27.1 ± 6.3%, with no significant differences between the groups. Patients without diabetes had lower mean interstitial glucose levels (81 vs. 94 and 98 mg/dl, p < 0.01) and lower glucose management indicator (GMI) (5.2 vs. 5.6 and 5.65%, p = 0.01) compared to the control and T2DM groups, respectively. The coefficient of variation (CV) significantly increased only in patients with diabetes (17% vs. 26.7%, p < 0.01). Both groups with (0% vs. 2%, p = 0.03) and without (3% vs. 22%, p = 0.03) T2DM experienced an increased time below range with low glucose (54-69 mg/dL). However, patients without T2DM had significantly less time in rage (70-180 mg/dL) (97% vs. 78%, p = 0.04). CONCLUSION: Significant differences in CGM metrics among RYGB patients suggest an increase in glycemic variability after surgery, with a longer duration of hypoglycemia, especially in patients without T2DM.

RESUMO

<b><br>Introduction:</b> Obesity's associated comorbidities and treatment costs have risen significantly, highlighting the importance of early weight loss strategies. Bariatric surgeries like Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) have been effective in promoting weight loss and improving type 2 diabetes mellitus (T2DM) management.</br> <b><br>Aim:</b> The aim was to determine whether Roux-en-Y gastric bypass is more effective than vertical sleeve gastrectomy in the remission of type 2 diabetes mellitus (T2DM).</br> <b><br>Methods:</b> A systematic review and meta-analysis was performed. A literature search was performed in the databases Web of Science, Medline/PubMed, Embase, Scopus, and Medline/Ovid. A total of 1323 results were identified; after screening, 14 articles were selected and included in the systematic review. Primary and secondary outcomes were measured by RR with a 95% CI.</br> <b><br>Results:</b> The primary outcome of T2DM remission was 15% in favor of VSG (RR: 1.15, [95% CI: 1.04-1.28]). For secondary outcomes, hypertension remission was 7% in favor of VSG (RR: 1.07, [95% CI: 1.00-1.16]). Remission of dyslipidemia was 16% in favor of VSG (RR: 1.16, [95% CI: 1.06-1.26]). BMI after surgery was in favor of RYGB (MD: -1.31, [95% CI: -1.98 to -0.64]). For weight loss, the results favored VSG (MD: 6.50, [95% CI: 4.99-8.01]). In relation to total cholesterol, they were 65% favorable for RYGB (MD: -0.35, [95% CI: -0.46 to -0.24]), with a value of p <0.05. For LDL values, our results were 69% favorable for RYGB (MD: -0.31, [95% CI: -0.45 to -0.16]), p <0.01 value.</br> <b><br>Conclusions:</b> Laparoscopic sleeve gastrectomy is more effective in T2DM remission, hypertension remission, dyslipidemia remission, and weight loss compared to Roux-en-Y gastric bypass. Roux-en-Y gastric bypass is more effective at lowering BMI, total cholesterol, LDL, and TG compared to laparoscopic sleeve gastrectomy.</br>.

RESUMO

INTRODUCTION: Bariatric surgery is established as a possibility for the treatment of obesity, allowing weight reduction and remission of obesity comorbidities. Reported suboptimal clinical response rates are as high as 30-60% (insufficient weight loss or gain, defined as BMI greater than 35 kg/m2 or excess weight loss less than 50%). Proximal jejuno-ileal bypass (PJIBP) is a promising option when re-intervention is required. OBJECTIVES: To describe the standardization of a proprietary technique of modified PJIBP as a management procedure in patients with post-gastric bypass recurrent weight gain or insufficient post-intervention weight loss. METHODS: This study evaluated a case series of 10 Latin American patients requiring post-bariatric re-intervention, between February 2018 and 2023, in a single-metabolic surgery center in Cali-Colombia. RESULTS: Median age was 45 years (26-70 RIC), 60% female, and 40% male. Mean BMI at conversion was 36.7 kg/m2 (6.4 SD). Median follow-up was 22 months (RIC 16-30). Mean percentage of excess weight lost was 78% (22.4 SD). One hundred percent achieved glycemia control, only one patient persisted with dyslipidemia, and no patient presented hypoalbuminemia. At the end of follow-up, 100% received vitamin supplementation. CONCLUSION: PJIBP could be an effective procedure, associated with positive results in relation to weight loss and resolution of obesity comorbidities. Deficiencies of fat-soluble vitamins and protein malnutrition represent the main concern in the long term, so multidisciplinary management and continuous follow-up are required.

RESUMO

PURPOSE: The use of a nonadjustable silicone band around the gastric pouch of Roux-en-Y gastric bypass (RYGB) to reduce the recurrence of obesity is still being debated in the literature. The primary objective of this study was to evaluate banded and non-banded RYGB regarding % total weight loss (%TWL) and complications up to 10 years postoperatively and regarding the removal rate of the silicone band. MATERIAL AND METHODS: A retrospective study of the medical records of all patients submitted to banded and non-banded RYGB between 2000 and 2020 was conducted. Clinical data (age, gender, weight, body mass index-BMI, comorbidities, %TWL, and the prevalence of vomiting) and laboratory data (hemoglobin, serum iron, albumin, and vitamin B12) were obtained preoperatively and at 6 months, 1, 2, 3, 5, 7, and 10 years for both groups and at 12, 15, and 20 years after banded RYGB. RESULTS: In total, 858 patients underwent RYGB: 409 underwent banded RYGB and 449 underwent non-banded RYGB. In the preoperative period, banded RYGB patients were heavier and had higher rates of hypertension and dyslipidemia. The %TWL was higher in the banded RYGB group up to 7 years. The prevalence of vomiting is much higher in this group, which also had lower laboratory test values. Of the banded RYGB patients, 9.53% had to have the silicone ring removed after presenting complications. CONCLUSION: Banded RYGB promotes significantly higher rates of TWL at the expense of a higher frequency of food intolerance and vomiting.

RESUMO

Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS) have been associated with significant reductions in bone mineral density (BMD) and fluctuations in serum levels of calciotropic hormones. These changes pose a risk to bone health. The study assessed the short-term (12 and 24 months) effects of RYGB and GS on BMD and calciotropic hormones. PubMed, Embase, and Cochrane Library databases were searched. Analyses considered follow-up (12 and 24 months) with BMD as main outcome at three sites (femoral neck, total hip, and lumbar spine) and one for each calciotropic hormone (25 OH vitamin D and parathyroid hormone [PTH]). Estimated effect sizes were calculated as standardized mean differences (SMD), confidence interval of 95%, and P value. Nine studies totaling 473 participants (RYGB = 261 and GS = 212) were included. RYGB resulted in lower BMD than GS at 12 months for femoral neck (SMD = -0.485, 95% CI [-0.768, -0.202], P = .001), lumbar spine (SMD = -0.471, 95% CI [-0.851, -0.092], P = .015), and total hip (SMD = -0.616, 95% CI [-0.972, -0.259], P = .001), and at 24 months for total hip (SMD = -0.572, 95% CI [-0.907, -0.238], P = .001). At 24 months, 25 OH vitamin D was lower in RYGB than GS (SMD = -0.958 [-1.670, -0.245], P = .008) and PTH levels were higher in RYGB than in GS (SMD = 0.968 [0.132, 1.804, P = .023]). RYGB demonstrated significant reduction in regional BMD. It also induces lower serum 25 OH vitamin D and higher PTH levels than GS. The results support the need for preventive bone health measures in the short-term postoperative period, especially in the case of RYGB.

RESUMO

Abstract Bile duct cysts are characterized by intrahepatic or extrahepatic bile duct dilation. It is a rare congenital pathology, diagnosed mainly in children. The clinical manifestation in adults is usually nonspecific but essential due to their increased risk of developing carcinoma. We present the case of a 37-year-old female patient who consulted for pain in the epigastrium radiating to the right hypochondrium, associated with emesis and choluria. The hepatobiliary ultrasound was normal, but due to the risk of choledocholithiasis, a magnetic resonance cholangiopancreatography was performed, revealing a cystic dilation of the proximal common bile duct of approximately 2 cm, classified as Todani type I. Bile duct cysts have been associated with several complications, and cholangiocarcinoma is the most important. The probability of malignancy is higher in adults and Todani type I cysts.


Resumen Los quistes de vía biliar se caracterizan por la dilatación de los conductos biliares intrahepáticos o extrahepáticos. Es una patología congénita poco frecuente, diagnosticada principalmente en niños. La presentación clínica en adultos suele ser inespecífica, pero importante debido a su riesgo aumentado de desarrollar carcinoma. Se presenta el caso de una paciente de 37 años que consulta por dolor en epigastrio irradiado al hipocondrio derecho, asociado a emesis y coluria. La ecografía hepatobiliar resultó normal, pero debido al riesgo de coledocolitiasis se realizó una colangiopancreatografía por resonancia magnética en la que se evidenció una dilatación quística del colédoco proximal de aproximadamente 2 cm, clasificada como Todani tipo I. Los quistes de vía biliar se han asociado a varias complicaciones, y el colangiocarcinoma es la más importante. La probabilidad de malignización es mayor en adultos y en los quistes Todani tipo I.

RESUMO

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.


Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

RESUMO

INTRODUCTION: Marginal ulcers are the most prevalent endoscopic abnormality after RYGB. The etiology is still poorly understood; however, an increase in acid secretion has been strongly implicated as a causal agent. Although gastrin is the greatest stimulant of acid secretion, to date, the presence of gastrin producing G cells retained in the gastric pouch, related to the occurrence of marginal ulcers, has not been evaluated. OBJECTIVE: Evaluate the density of G cells and parietal cells in the gastric pouch of RYGB patients with a diagnosis of marginal ulcer on the post-op EGD. METHOD: We retrospectively evaluated 1104 gastric bypasses performed between 2010 and 2020. Patients with marginal ulcer who met the inclusion criteria and controls were selected from this same population. Endoscopic gastric pouch biopsies were evaluated using immunohistochemical study and HE staining to assess G cell and parietal cell density. RESULTS: In total, 572 (51.8%) of the patients performed endoscopic follow-up after RYGB. The incidence of marginal ulcer was 23/572 (4%), and 3 patients required revision surgery due to a recalcitrant ulcer. The mean time for ulcer identification was 24.3 months (2-62). G cell count per high-power field (× 400) was statistically higher in the ulcer group (p < 0.05). There was no statistical difference in parietal cell density between groups (p 0.251). CONCLUSION: Patients with a marginal ulcer after gastric bypass present a higher density of gastrin-producing G cells retained in the gastric pouch.

RESUMO

Introducción: La panlitiasis se define como la presencia de múltiples cálculos en el trayecto de la vía biliar. El manejo consiste en realizar una colangiopancreatografía retrógrada endoscópica (CPRE), la exploración de la vía biliar o la anastomosis biliodigestiva (ABD), ya sea coledocoduodenoanastomosis o hepaticoyeyunoanastomosis.Objetivo: Describir el caso clínico de un paciente con panlitiasis biliar, abordando la presentación clínica, los métodos diagnósticos, el tratamiento y la evolución, con el propósito de ofrecer un recurso sólido a la comunidad médica.Presentación del caso: Se presenta un paciente de 60 años colecistectomizado hace 13 años portador de anastomosis bilioentérica con panlitiasis recidivante, se realizó un lavado de la vía biliar con salida de cálculos y pus del interior, finalmente se colocó una sonda Kehr junto con tratamiento clínico. Presentó una evolución favorable. Discusión: Este caso reveló una panlitiasis a la exploración de las vías biliares bajo visión endoscópica, a pesar de que no se encontró obstrucción, el paciente tenía antecedente de colecistectomía y contaba con una derivación hepático-yeyunal por lesión iatrogénica. La decisión del tratamiento debe ser multidisciplinaria ya que cada caso es único y dependerá de las características del paciente y las condiciones clínicas individuales.Conclusiones: La panlitiasis coledociana recidivante requirió un control farmacológico estricto para evitar recurrencia y la subsecuente exploración de la vía biliar que incrementa la morbimortalidad del paciente. Es importante el seguimiento médico continuo del paciente y la predisposición con la que cuenta para la formación de litos, pudiendo ser prevenidos, identificados y tratados de manera oportuna


Introduction: Panlithiasis is define as the presence of multiple stones in the biliary tract that is classified as primary, secondary, or mixed according to the origin of the stones. Management consists of endoscopic retrograde cholangiopancreatography (ERCP), exploration of the biliary tract, or biliodigestive anastomosis (BDA), either choledochoduodenostomy or hepaticojejunostomy. Objective: Describe the clinical case of a patient with biliary panlithiasis, addressing the cli-nical presentation, diagnostic methods, treatment and evolution, with the purpose of offering a solid resource to the medical community.Case Presentation: We present a 60-year-old male patient who underwent cholecystectomy 13 years ago and has a bilioenteric anastomosis with recurrent panlithiasis. Biliary lavage was performed with the output of stones and pus from the inside. Finally, a Kehr tube was placed along with clinical treatment. The patient showed a favorable outcome.Discussion: This case revealed a panlithiasis upon exploration of the biliary tract under endoscopic vision. Despite finding no obstruction, the patient had a history of cholecystectomy and a hepatic-jejunal diversion due to iatrogenic injury. The treatment decision should be multidisciplinary, as each case is unique and depends on the patient's characteristics and individual clinical conditions.Conclusions: Recurrent choledocholithiasis required strict pharmacological control to prevent recurrence and subsequent exploration of the biliary tract, which increases patient morbidity and mortality. Continuous medical follow-up of the patient and the predisposition with which they have for the formation of stones is important. These can be prevented, identified, and treated in a timely manner.

RESUMO

ABSTRACT BACKGROUND: Evidence on the effect of one-anastomosis gastric bypass (OAGB) on renal function is limited. OBJECTIVE: To compare the evolution of estimated renal function observed 1 year after OAGB and Roux-en-Y gastric bypass (RYGB) in individuals with obesity. DESIGN AND SETTING: Observational, analytical, and retrospective cohort study. Tertiary-level university hospital. METHODS: This study used a prospectively collected database of individuals who consecutively underwent bariatric surgery. Renal function was assessed by calculating the estimated glomerular filtration rate (eGFR), according to the Chronic Kidney Disease Epidemiology Collaboration. The one-year variation in the eGFR was compared between the procedures. RESULTS: No significant differences in age, sex, obesity-associated conditions, or body mass index were observed among individuals who underwent either OAGB or RYGB. OAGB led to a significantly higher percentage of total (P = 0.007) and excess weight loss (P = 0.026). Both OAGB and RYGB led to significantly higher values of eGFR (103.9 ± 22 versus 116.1 ± 13.3; P = 0.007, and 102.4 ± 19 versus 113.2 ± 13.3; P < 0.001, respectively). The one-year variation in eGFR was 11 ± 16.2% after OAGB and 16.7 ± 26.3% after RYGB (P = 0.3). Younger age and lower baseline eGFR were independently associated with greater postoperative improvement in renal function (P < 0.001). CONCLUSION: Compared with RYGB, OAGB led to an equivalent improvement in renal function 1 year after the procedure, along with greater weight loss.

RESUMO

ABSTRACT BACKGROUND: Curative treatment for gastric cancer involves tumor resection, followed by transit reconstruction, with Roux-en-Y being the main technique employed. To permit food transit to the duodenum, which is absent in Roux-en-Y, double transit reconstruction has been used, whose theoretical advantages seem to surpass the previous technique. AIMS: To compare the clinical evolution of gastric cancer patients who underwent total gastrectomy with Roux-en-Y and double tract reconstruction. METHODS: A systematic review was carried out on Web of Science, Scopus, EmbasE, SciELO, Virtual Health Library, PubMed, Cochrane, and Google Scholar databases. Data were collected until June 11, 2022. Observational studies or clinical trials evaluating patients submitted to double tract (DT) and Roux-en-Y (RY) reconstructions were included. There was no temporal or language restriction. Review articles, case reports, case series, and incomplete texts were excluded. The risk of bias was calculated using the Cochrane tool designed for randomized clinical trials. RESULTS: Four studies of good methodological quality were included, encompassing 209 participants. In the RY group, there was a greater reduction in food intake. In the DT group, the decrease in body mass index was less pronounced compared to preoperative values. CONCLUSIONS: The double tract reconstruction had better outcomes concerning body mass index and the time until starting a light diet; however, it did not present any advantages in relation to nutritional deficits, quality of life, and post-surgical complications.


RESUMO RACIONAL: O tratamento curativo do câncer gástrico envolve a ressecção do tumor, seguida de reconstrução do trânsito, sendo o Y-de-Roux a principal técnica empregada. Para permitir o trânsito alimentar para o duodeno, ausente em Y-de-Roux, tem-se utilizado a reconstrução de duplo trânsito, cujas vantagens teóricas parecem superar a técnica anterior. OBJETIVOS: Comparar a evolução clínica de pacientes com câncer gástrico submetidos à gastrectomia total com Y-de-Roux e reconstrução de duplo trânsito. MÉTODOS: Foi realizada uma revisão sistemática nas bases de dados: Web of Science, Scopus, Embase, Scielo, Biblioteca Virtual em Saúde, PubMed e Cochrane. Os dados foram coletados até 11 de junho de 2022. Foram incluídos estudos observacionais ou ensaios clínicos avaliando pacientes que utilizaram reconstruções de duplo trânsito (DT) e Y-de-Roux (RY). Não houve restrição temporal ou de idioma. Foram excluídos artigos de revisão, relatos de casos, séries de casos e aqueles com texto incompleto. O risco de viés foi calculado utilizando a ferramenta Cochrane desenvolvida para ensaios clínicos randomizados. RESULTADOS: Foram incluídos quatro estudos de boa qualidade metodológica, abrangendo 209 participantes. No grupo RY houve maior redução na ingestão alimentar. No grupo DT, a diminuição do índice de massa corporal (IMC) foi menos pronunciada em comparação aos valores pré-operatórios. CONCLUSÕES: A reconstrução de duplo trânsito apresentou melhores resultados em relação ao índice de massa corporal e ao tempo para início de dieta leve, porém não apresentou vantagens em relação aos déficits nutricionais, qualidade de vida e complicações pós-cirúrgicas.

RESUMO

Various complications occur after a biliary-digestive reconstruction. Volvulus of a segment of the biliodigestive loop has not been described. Two patients who underwent biliodigestive bypass, years later, began with sudden and intense abdominal pain, associated with a volvulus with necrosis of a segment of this biliodigestive loop. This complication occurred many years after the initial correction, and manifested with sudden abdominal pain without impaired liver function, as occurred in these patients.


Diversas complicaciones pueden ocurrir después de una reconstrucción biliodigestiva. El vólvulo de un segmento del asa biliodigestiva no ha sido descrito. Dos pacientes operados de derivación biliodigestiva, años después iniciaron con dolor abdominal súbito e intenso, asociado a un vólvulo con necrosis de un segmento de la asa interpuesta. Se ha descrito el vólvulo de toda el asa interpuesta, pero no el de solo una pequeña porción de esta. La complicación ocurrió muchos años después de la corrección inicial y se manifiesto con dolor abdominal súbito sin deterioro de la función hepática, como sucedió en estos pacientes.

RESUMO

INTRODUCTION: After Roux-en-Y gastric bypass (RYGB), the basal metabolic rate (BMR) falls. However, it is important to know how BMR per kilogram of body weight (BMR/kg) varies in the postoperative period. The present study evaluated the changes in the BMR/kg and its correlates over 30 months after RYGB. METHODS: Eighty adult patients of both genders who underwent RYGB agreed to participate in the study. The following evaluations were performed before surgery (n=48) and 6 (n=27), 12 (n=28), 24 (n=40), and 30 months (n=29) after surgery: anthropometry, body composition (bioelectrical impedance), metabolic analysis (indirect calorimetry), and diet (food recall). Statistical analysis was performed (p = 0.05). RESULTS: Although BMR decreased after surgery, BMR/kg increased significantly as compared to baseline from 12 months onward, peaking at 24 months and not significantly dipping at 30 months, suggesting stabilization of BMR/kg 2 years after surgery (pre, 10.68 ± 2.33 kcal/kg; 12 months, 12.46 ± 2.85 kcal/kg; 24 months, 18.78 ± 4.81 kcal/kg; 30 months, 18.12 ± 3.69 kcal/kg; p <0.001). Regarding the variables that influenced the BMR/kg, at 12 months, they were %LBM and intake of calcium-source foods (34%); at 24 months, it was protein intake (16%); and at 30 months, it was the intake of calcium-source foods (26.7%). CONCLUSION: RYGB is associated with a significant increase in BMR when it is adjusted to body weight from 12 to 24 months postoperatively. Among the factors involved in the increase in BMR/kg are body composition and intake of protein-rich foods.

RESUMO

INTRODUCTION: At the beginning of the pandemic, studies showed a higher risk of severe surgical complications and mortality among patients with perioperative SARS-CoV-2 infection, which led to the suspension of elective surgery. Confinement and lockdown measures were shown to be associated with weight gain and less access to medical and surgical care in patients with obesity, with negative health consequences. To evaluate the safety of bariatric surgery during the pandemic, we compared 30-day complications between patients who underwent bariatric surgery immediately before with those who underwent bariatric surgery during the opening phase of the pandemic. METHODS: Observational analytical study of a non-concurrent cohort of patients who underwent bariatric surgery in 2 periods: pre-pandemic March 1 to December 31, 2019, and pandemic March 1 to December 31, 2020. Surgical complications were defined using the Clavien-Dindo classification. RESULTS: Pre-pandemic and pandemic groups included 256 and 202 patients who underwent primary bariatric surgery, respectively. The mean age was 37.6 + 10.3 years. The overall complication rate during the first 30 days of discharge was 7.42%. No differences between groups were observed in severe complications (pre-pandemic 1.56% vs. pandemic 1.98%, p: 0.58). No mortality was reported. Overall 30-day readmission was 3.28% with no differences between groups. CONCLUSION: The findings of this study did not find a difference in the rate of severe complications, nor also we report severe COVID-19 complications in this high-risk population. During the pandemic, with appropriately implemented protocol, the resumption of bariatric surgery is possible with no increased risk for patients.

RESUMO

Resumen Introducción: La cirugía bariátrica se considera actualmente la opción de tratamiento más eficaz para la obesidad mórbida. El bypass gástrico laparoscópico en Y de Roux sigue siendo el estándar de oro en cirugía bariátrica. El advenimiento de la robótica quirúrgica ha llevado a una reducción de algunos de los desafíos más difíciles en la laparoscopia avanzada. Objetivo: Determinar la seguridad y eficacia del bypass gástrico en Y de Roux asistido por robot en comparación con el abordaje laparoscópico. Material y métodos: Se realizó un estudio retrospectivo que incluyo 50 pacientes con distintos grados de obesidad divididos en dos grupos de 25 cada uno. Se realizó una base de datos con las variables de acuerdo al tipo de abordaje quirúrgico (robótico y laparoscópico), registrando los días de estancia hospitalaria, sangrado, tiempo quirúrgico, complicaciones, reingresos hospitalarios, complicaciones y disminución del IMC. Resultados: En el grupo laparoscópico se observó un sangrado transoperatorio de 115.8+64 mililitros, en el grupo robótico solo fue de 59.6+45.8 mililitros (p<0.001). Un tiempo quirúrgico laparoscópico de 151.8+34.6 minutos, mientras que el grupo robótico fue de 216.4+50 minutos, los pacientes permanecieron hospitalizados 4.2+2.4 días en el grupo laparoscópico, los pacientes del grupo robótico 3.4+1 días, sin diferencia significativa (p=0.077). En ambos grupos no hubo reingresos hospitalarios. En el grupo laparoscópico la disminución de IMC fue de 8.9+2.5, mientras que para el grupo robótico fue de 13.7+2.3 con significancia estadística (p<0.001). Discusión: El bypass gástrico en Y de Roux asistido por robot es más seguro y eficaz en comparación con el abordaje laparoscópico. El abordaje robótico disminuye de forma significativa el sangrado transoperatorio, disminuye los días de estancia hospitalaria (sin diferencia significativa) y reduce de forma significativa la disminución del IMC, sin aumentar los reingresos hospitalarios a 30 días ni las complicaciones.


Abstract Introduction: Bariatric surgery is currently considered the most effective treatment option for morbid obesity. The laparoscopic Roux-en-Y gastric bypass remains the gold standard in bariatric surgery. The advent of surgical robotics has led to a reduction in some of the most difficult challenges in advanced laparoscopy. Objective: To determine the safety and efficacy of robot-assisted Roux-en-Y gastric bypass compared to the laparoscopic approach. Material and methods: A retrospective study was carried out that included 50 patients with different degrees of obesity divided into two groups of 25 patients each. A database was created with the variables according to the type of surgical approach (robotic and laparoscopic), recording the days of hospital stay, bleeding, surgical time, complications, hospital readmissions, complications, and BMI decrease. Results: In the laparoscopic group, intraoperative bleeding of 115.8+64 milliliters was observed, in the robotic group it was only 59.6+45.8 milliliters (p<0.001). A laparoscopic surgical time of 151.8+34.6 minutes, while the robotic group was of 216.4+50 minutes, the patients remained hospitalized 4.2+2.4 days in the laparoscopic group, the patients in the robotic group 3.4+1 days, with no significant difference (p=0.077). In both groups there were no hospital readmissions. In the laparoscopic group, the decrease in BMI was 8.9+2.5, while for the robotic group it was 13.7+2.3 with statistical significance (p<0.001). Discussion: Robot-assisted Roux-en-Y gastric bypass is more safe and effective compared to the laparoscopic approach. The robotic approach significantly reduces intraoperative bleeding, decreases the days of hospital stay (with no significant difference), and significantly reduces the decrease in BMI, without increasing 30-day hospital readmissions or complications.

RESUMO

Sarcopenic obesity is characterized by a disproportion between the amount of muscle to fat. Contrary to most studies evaluating parameters related to sarcopenic obesity in the elderly, this study aims to evaluate the phase angle (PhA) and sarcopenia in young individuals pre- and post-Roux-en-Y gastric bypass. A total of 69 volunteers (46 women and 23 men; 38.5 ± 8.1 years) participated in this study. Body composition and PhA were assessed using BIA. Sarcopenia was assessed using a handgrip strength test (HGS) and gait speed (GS), and appendicular lean mass (ALM) was assessed using Dual Energy X-ray Absorptiometry (DXA). The PhA was significantly lower (p < 0.0007) and the resistance (R) significantly higher (p = 0.0026) in the postoperative group. HGS was negatively correlated with R (r = -0.63669; p < 0.0001), hs-CRP (r = -0.45436; p = 0.0197), and leptin (r = -0.46505; p = 0.0043). GS was negatively correlated with R (r = -0.36220; p = 0.0254), and ALM was negatively correlated with reactance (r = -0.49485; p = 0.0034) and R (r = -0.65797; p ≤ 0.0001). PhA and other components of BIA provide a good correlation with sarcopenia, especially regarding the reduction in muscle function, in an early form, in individuals in the pre- and postoperative period of gastric bypass.

RESUMO

Obesity is a troubling public health problem as it increases risks of sleep disorders, respiratory complications, systemic arterial hypertension, cardiovascular diseases, type 2 diabetes mellitus, and metabolic syndrome (MetS). As a measure to counteract comorbidities associated with severe obesity, bariatric surgery stands out. This study aimed to investigate the adiponectin/leptin ratio in women with severe obesity with and without MetS who had undergone Roux-en-Y gastric bypass (RYGB) and to characterize the biochemical, glucose, and inflammatory parameters of blood in women with severe obesity before and after RYGB. Were enrolled females with severe obesity undergoing RYGP with MetS (n = 11) and without (n = 39). Anthropometric data and circulating levels of glucose, total cholesterol, high-density lipoprotein (HDL), non-HDL total cholesterol, low-density lipoprotein (LDL), adiponectin, and leptin were assessed before and 6 months after RYGB. Significant reductions in weight, body mass index, and glucose, total cholesterol, LDL, and leptin were observed after surgery, with higher levels of HDL, adiponectin, and adiponectin/leptin ratio being observed after surgery compared to the preoperative values of those. This study demonstrated that weight loss induced by RYGB in patients with severe obesity with or without MetS improved biochemical and systemic inflammatory parameters, particularly the adiponectin/leptin ratio.
