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 Roux-en-Y gastric bypass, a procedure proven effective for treating morbid obesity and metabolic disorders, carries the risk of complications such as the formation of internal hernias. These hernias are often difficult to diagnose and can be potentially fatal because they can cause structural obstruction. Most internal hernias occur in the jejunojejunostomy mesentery space, followed by Petersen's space hernias, although herniation at other locations can also occur. Our case report presents an example of a rare internal hernia after laparoscopic Roux-en-Y gastric bypass. A 36-year-old woman presented with an uncommon internal hernia located between the liver and alimentary loop, resulting in the formation of a new space and consequently incarcerating the entire biliopancreatic loop. This type of internal hernia is rare and has not been reported in the literature, indicating that this is the first report of such a case. In this case, we realized that the diagnosis was challenging and imaging examinations could not help determine the etiology of the pain and obstruction. Therefore, videolaparoscopy revealed an uncommon hernia formed by firm adhesion between the hepatic segment III and the alimentary loop mesentery. Our case is an example of an internal hernia that was not detected with a normal computed tomography scan of the abdomen and pelvis. Only diagnostic laparoscopy revealed herniation, effectively preventing further complications for the patient.

RESUMO

Abstract Introduction: Post-surgical esophagojejunal anastomosis fistulas can be life-threatening. Currently, there are several treatment alternatives. In recent years, endoscopic negative pressure therapy has emerged as an innovative treatment for these fistulas, offering numerous benefits. Case presentation: A 72-year-old man diagnosed with gastric adenocarcinoma of the body and fundus underwent total gastrectomy with D2 lymphadenectomy and Roux-en-Y anastomosis with curative intent in a quaternary care hospital in Popayán, Colombia. However, in the postoperative period, he presented systemic inflammatory response syndrome and acute abdomen due to an esophagojejunal fistula. Initial management included a laparotomy, two peritoneal washings, and an abdominal drainage. Then the patient developed frozen abdomen, so it was not possible to access the esophagojejunal anastomosis. Fistula closure was attempted by inserting a self-expandable metallic stent, yet the procedure was not successful. Salvage therapy was started using an endoscopic vacuum-assisted closure (VAC) system. After 5 replacements of the VAC system, complete drainage of the intra-abdominal collection, complete closure of the peritoneal cavity, and closure of the esophagojejunal leak, with a small residual diverticular formation, were achieved. The patient's condition improved progressively, resuming oral intake 20 days after initiation of VAC therapy. In addition, no new abdominal complications were reported during the follow-up period (17 months). Conclusions: Endoscopic VAC therapy is a new safe and effective alternative to treat complex post-surgical fistulas caused by esophagojejunal anastomosis.

Resumen Introducción. Las fístulas de las anastomosis esófago-yeyunales postquirúrgicas pueden llegar a ser mortales. En la actualidad, existen varias alternativas de tratamiento, y en los últimos años la terapia endoscópica de presión negativa se ha convertido en un método innovador y con grandes ventajas para el manejo de estas fístulas. Presentación del caso. Hombre de 72 años diagnosticado con adenocarcinoma gástrico de cuerpo y fondo a quien se le realizó una gastrectomía total con linfadenectomía D2 y una anastomosis en Y de Roux con intención curativa en un hospital de cuarto nivel en Popayán, Colombia. Sin embargo, en el posoperatorio presentó síndrome de respuesta inflamatoria sistémica y abdomen agudo producto de fístula esófago-yeyunal. Se realizó manejo inicial con laparotomía, dos lavados de cavidad peritoneal y drenaje abdominal. Posteriormente, el paciente desarrolló abdomen congelado, por lo que no fue posible acceder a la anastomosis esófago-yeyunal. Se intentó cierre de fístula mediante la inserción de prótesis metálica autoexpandible, pero el procedimiento no fue exitoso. Se inició terapia de rescate mediante sistema de cierre asistido por vacío (VAC) por vía endoscópica. Luego de 5 recambios del sistema VAC, se logró el drenaje completo de la colección intraabdominal encontrada, el cierre completo de la cavidad peritoneal y el cierre de la fuga esófago-yeyunal, con una pequeña formación diverticular residual. La condición del paciente mejoró progresivamente, con reinicio de la vía oral a los 20 días del inicio de la terapia VAC. Además, no se reportaron nuevas complicaciones abdominales en el periodo de seguimiento (17 meses). Conclusión. La terapia endoscópica de VAC es una nueva alternativa segura y efectiva para el tratamiento de fístulas postquirúrgicas complejas producto de anastomosis esófago-yeyunales.

RESUMO

ABSTRACT Introduction: laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has been a revolutionary intervention for weight loss with reduction of up to 60-70% of excess body weight. However, these outcomes are not as well validated at the extremes of age, where the safety of the intervention still has some caveats. The aim of this study is to assess the efficacy and safety of primary LRYGB among different age groups. Methods: the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried for patients who underwent primary LRYGB from January 2014 to December 2017 at a single institution. Four groups were created and compared by dividing our sample by age quartiles. The primary outcome was percent excess weight loss (%EWL) at 1 year. Additional operative outcomes and complications were also compared across groups. Results: a total of 1013 patients underwent non-revisional LRYGB during the study period. Mean %EWL at one year was 55%. When compared between quartiles, there was a statistically significant difference in %EWL: 1st 62%, 2nd 57%, 3rd 54% and 4th 47% (p=0.010). The differences in the secondary outcomes between age groups did not demonstrate statistical significance. Conclusions: though patients in the fourth age quartile (range) did not demonstrate a statistically significant increase in adverse outcomes, they did lose less weight compared to other cohorts. The %EWL at one year after RYGB varied by age in our cohort. Goals after bariatric surgery should be individualized as weight loss is less robust with aging.

RESUMO Introdução: o Bypass Gástrico Laparoscópico em Y de Roux (LRYGB) tem sido uma intervenção revolucionária para perda de peso com redução de até 60-70% do excesso de peso corporal. No entanto, esses resultados não são tão bem validados nos extremos de idade, onde a segurança da intervenção ainda possui algumas ressalvas. O objetivo deste estudo é avaliar a eficácia e segurança do LRYGB entre diferentes faixas etárias. Métodos: O banco de dados do Programa de Acreditação e Melhoria da Qualidade da Cirurgia Metabólica e Bariátrica (MBSAQIP) foi consultado para pacientes submetidos a LRYGB de janeiro de 2014 a dezembro de 2017 em uma única instituição. Quatro grupos foram criados e comparados dividindo a amostra por quartis de idade. O desfecho primário foi perda percentual de excesso de peso (%EWL) em 1 ano. Resultados: 1013 pacientes foram submetidos a LRYGB durante o período do estudo. A média de %EWL em um ano foi de 55%. Quando comparados entre os quartis, houve diferença significante no %EWL: 1º 62%, 2º 57%, 3º 54%, e 4º 47% (p=0,010). As diferenças nos desfechos secundários entre as faixas etárias não demonstraram significância estatística. Conclusões: embora os pacientes no quarto quartil de idade não tenham demonstrado um aumento estatisticamente significativo nos resultados adversos, eles perderam menos peso em comparação com outras coortes. O %EWL um ano após RYGB variou de acordo com a idade em nossa coorte. Os objetivos após a cirurgia bariátrica devem ser individualizados, pois a perda de peso é menos robusta com o envelhecimento.

RESUMO

RESUMO - RACIONAL: Os fatores relacionados à perda de peso nos pacientes obesos submetidos à cirurgia bariátrica sempre foram exaustivamente estudados na tentativa de propor a melhor técnica cirúrgica com maior perda de peso e resolução as comorbidades à longo prazo. Os pacientes apresentam variações anatômicas no que tange o comprimento do intestino delgado. Há estudos que demonstram alterações de peso nos pacientes que apresentam diferentes comprimentos das alças intestinais na técnica do by-pass em Y de Roux. O presente trabalho realizou um estudo entre a influência do IMC, a perda de peso e o comprimento da alça comum nos resultados cirúrgicos à longo prazo. MÉTODOS: Estudo transversal descritivo pela análise retrospectiva de 112 prontuários de pacientes submetidos à cirurgia bariátrica aberta pela técnica do bypass gástrico no Hospital de Clínicas -UFPR. Os dados foram correlacionados em programas estatísticos para este fim. RESULTADOS: Dos 112 pacientes, 83,03% eram do sexo feminino, média de idade de 41,52 anos. O comprimento médio do intestino delgado total dos pacientes foi de 5,02 metros. Houve uma relação diretamente proporcional entre o comprimento do intestino delgado e a perda de peso (p=0,0428). CONCLUSÃO: Há uma ampla gama de variáveis relacionadas à perda de peso nos pacientes submetidos à cirurgia bariátrica, tais como a técnica utilizada, o comprimento das alças no by-pass gástrico em Y de Roux e a rotina de acompanhamento nutricional e físico do paciente. É importante considerar os detalhes técnicos do procedimento cirúrgico, e verificar a perda de peso avaliando-se o paciente como um todo e outras variáveis.

ABSTRACT - BACKGROUND: Factors related to weight loss in obese patients undergoing bariatric surgery have always been exhaustively studied in an attempt to propose the best surgical technique with greater weight loss and long-term resolution of comorbidities. Patients present anatomical variations regarding the length of the small intestine. Some studies demonstrate weight changes in patients with different lengths of the intestinal loops in the Roux-en-Y bypass technique. The present work carried out a study on the influence of body mass index, weight loss, and common loop length on long-term surgical outcomes. METHODS: This is a descriptive cross-sectional study by retrospective analysis of 112 medical records of patients undergoing open bariatric surgery using the gastric bypass technique at University Hospital - UFPR. The data were correlated in statistical programs for this purpose. RESULTS: Out of 112 patients, 83.03% were women, with mean age of 41.52 years. The mean length of the total small bowel of the patients was 5.02 m. There was a directly proportional relationship between the length of the small intestine and weight loss (p=0.0428). CONCLUSION: There is a wide range of variables related to weight loss in patients undergoing bariatric surgery, such as the technique used, the length of the loops in the Roux-en-Y gastric bypass, and the routine of nutritional and physical monitoring of the patient. It is important to assess the technical details of the surgical procedure and to verify the weight loss by evaluating integrally the patient and other variables.

RESUMO

ABSTRACT Background: The increased prevalence of obesity has led to a significant increase in the occurrence of metabolic syndrome, a recognized risk factor for increased morbidity and mortality from cardiovascular diseases. Hyperglycemia or type 2 diabetes mellitus, dyslipidemia and arterial hypertension are its main components. Since 2015, international guidelines have recognized the benefits of bariatric surgery in each isolated factor of this syndrome. Aim: To evaluate the impact of Roux-en-Y gastric bypass in this syndrome comparing pre- and postoperative periods with laboratory analysis and to compare waist/height ratio and BMI in relation to the determination of the cardiometabolic risk profile. Methods: A retrospective study was carried out, selecting 80 patients undergoing Roux-en-Y gastric bypass. Total cholesterol, HDL, LDL, triglycerides, fasting glucose, glycated hemoglobin, insulin, body mass index (BMI), vitamin D, vitamin B12, waist circumference and waist/height ratio in three periods were analyzed: the preoperative period from 1 to 6 months, postoperative from 1 to 6 months and postoperative from 1 to 2 years. Results: There was an improvement in all parameters of the clinical analyses. The preoperative BMI had a mean value of 39.8, in the preoperative period from 1 to 6 months, the values ​​dropped to 33.2 and in the postoperative period of 1 year, the mean was 26. The perimeter mean values ​​of 118.5 preoperatively, 105.2 postoperatively from 1 to 6 months and 90.3 postoperatively from 1 to 2 years. Waist/height ratio was 0.73, 0.65 and 0.56 in pre, post 1 to 6 months and 1 to 2 years respectively. Conclusion: Roux-en-Y gastric bypass improves metabolic syndrome and waist-to-height ratio is superior to BMI in the assessment of the cardiometabolic risk profile.

RESUMO Racional: O aumento da prevalência da obesidade levou ao aumento significativo da ocorrência de síndrome metabólica, fator de risco reconhecido para aumento da morbimortalidade por doenças cardiovasculares. A hiperglicemia ou diabetes mellitus do tipo 2, dislipidemia e hipertensão arterial são seus principais componentes. Desde 2015, diretrizes internacionais reconheceram os benefícios da cirurgia bariátrica em cada fator isolado desta síndrome. Objetivos: Avaliar o impacto do bypass gástrico em Y-de-Roux nesta síndrome comparando períodos pré e pós-operatório com análise laboratorial, e comparar a razão cintura/estatura e o IMC em relação a determinação do perfil de risco cardiometabólico. Métodos: Realizou-se um estudo retrospectivo com base prospectiva selecionando 80 pacientes submetidos à bypass gástrico em Y-de-Roux. Foram analisados o colesterol total, HDL, LDL, triglicerídeos, glicemia de jejum, hemoglobina glicada, insulina, índice de massa corpórea (IMC), vitamina D, vitamina B12, perímetro abdominal e relação cintura/estatura em três períodos: o pré-operatório de 1 a 6 meses, pós-operatório de 1 a 6 meses e pós-operatório de 1 a 2 anos. Resultados: Houve melhora em todos os parâmetros das análises clínicas. O IMC, no pré-operatório, teve a média dos valores de 39,8, no pré-operatório de 1 a 6 meses, os valores caíram para 33,2 e no pós-operatório de 1 ano média foi de 26. O perímetro abdominal teve média dos valores de 118,5, no pré-operatório, 105,2 no pós-operatório de 1 a 6 meses e 90,3 no pós-operatório de 1 a 2 anos. A relação cintura/estatura teve 0,73, 0,65 e 0,56 no pré, pós 1 a 6 meses e 1 a 2 anos respectivamente. Conclusão: O bypass gástrico em Y-de-Roux melhora a síndrome metabólica e a relação cintura/estatura é superior ao IMC na avaliação do perfil do risco cardiometabólico.

RESUMO

La anastomosis hepático-yeyuno en Y de Roux se considera la técnica de elección para tratar lesiones quirúrgicas de la vía biliar, como su sección o resección. La pérdida de confluencia de los conductos hepáticos principales derecho e izquierdo es uno de los factores que incrementan la complejidad técnica durante el procedimiento y, en algunos de estos pacientes, se requiere una doble anastomosis hepático-yeyuno para garantizar resultados satisfactorios a largo plazo. Se describen los aspectos técnicos y los resultados posoperatorios del tratamiento quirúrgico empleado, con base en la intervención de una paciente con una lesión quirúrgica de la vía biliar y pérdida de la confluencia de los conductos hepáticos. La evolución de la paciente fue satisfactoria y se mantiene asintomática después de 12 meses de seguimiento. A pesar de ser una técnica compleja, la doble anastomosis hepático-yeyuno en Y de Roux resultó una opción segura de tratamiento en esta paciente

Roux-en-Y hepato-jejunostomy (RYHJ) is the technique of choice for the surgical treatment of bile duct injuries (BDI), such as section or resection. The loss of the hepatic confluence (LHC) increases the technical difficulties during the procedure and, in some of these patients, a doble-RYHJ is required to achieve a long term successful result. We report the technical aspects of the surgical technique as well as the results, based on the case of a young female patient with BDI and LHC. The patient shows a satisfactory evolution and remains asymptomatic during the 12 months of follow up. Double RYHJ, although technically demanding, resulted a safe option for treating this patient

RESUMO

ABSTRACT Objective: to describe the first 13 cases of laparoscopic correction of common bile duct cyst in the Pequeno Príncipe Hospital, Curitiba, Paraná, Brazil. Methods: we performed a retrospective analysis of medical records of cases of choledochal cyst operated by laparoscopy between March 2014 and September 2016. Results: of the 13 patients, eight were female and the mean age at surgery was 7.8 years. The most common symptom was abdominal pain. The hepaticoduodenal anastomosis was the most used reconstruction technique, in 84.6% of the cases. There was no conversion to laparotomy or intraoperative complications. Only one patient presented anastomotic fistula and was reoperated by laparotomy. All patients were followed up in an outpatient clinic, were asymptomatic and had no episode of cholangitis after surgery, with a mean follow-up of 16 months. Conclusion: laparoscopy is a safe method to correct choledochal cysts, even in younger children, with low rates of complications and low rates of conversion to open surgery when performed by well trained surgeons.
