BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT.

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

Large hiatal hernias (LHH) besides being more prevalent in the elderly, have different clinical presentation: fewer reflux, more mechanical symptoms and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease (GERD-related), sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index (BMI above 35), age over 70 years and presence of comorbidity. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, case-by-case analysis of surgical risk factors such as age, obesity and comorbidities, should be taken under consideration. One should also pay attention to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual workers, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of LHH in high-volume centers, with experienced surgeons.

As grandes hérnias de hiato (HHG), além de serem mais prevalentes em idosos, têm apresentação clínica diferente: menos refluxo, mais sintomas mecânicos e maior possibilidade de complicações agudas e potencialmente fatais, como vólvulo gástrico, isquemia e perfuração mediastinal visceral. Assim, as indicações cirúrgicas são distintas das hérnias de hiato por deslizamento, relacionadas à doença do refluxo gastroesofágico (DRGE). A azia tende a ser menos intensa, enquanto os sintomas de dor no peito, tosse, desconforto e cansaço são relatados com maior frequência. Queixas de vômitos e disfagia podem sugerir a presença de volvo gástrico associado. São encontrados sinais de deficiência de ferro e anemia. A indicação cirúrgica ainda é controversa e foi anteriormente baseada na alta mortalidade relatada em cirurgias de emergência para volvo gástrico. A mortalidade pós-operatória está especialmente relacionada a três fatores: índice de massa corporal (IMC acima de 35), idade superior a 70 anos e presença de comorbidades. A cirurgia eletiva minimamente invasiva deve ser oferecida a indivíduos sintomáticos, com desempenho bom ou razoável, independentemente da faixa etária. Em pacientes assintomáticos e oligossintomáticos, além de obviamente identificar o desejo do paciente, deve-se levar em consideração a análise caso a caso dos fatores de risco cirúrgico, como idade, obesidade e comorbidades. Deve-se atentar também para situações de maior dificuldade técnica e riscos de migração aguda por aumento da pressão abdominal (abdominoplastia, trabalhos manuais, doenças espásticas). Alternativas técnicas como fundoplicatura parcial e gastropexia anterior podem ser consideradas. Ressaltamos a importância da realização de procedimentos cirúrgicos nos casos de GHH em centros de grande volume, com cirurgiões experientes.

IMPACT OF BODY MASS INDEX ON PERIOPERATIVE OUTCOMES FOR COMPLEX HIATUS HERNIA BY VIDEOLAPAROSCOPY.

BACKGROUND: The influence of body mass index on perioperative complications of hiatal hernia surgery is controversial in the surgical literature. AIMS: The aim of this study was to evaluate the influence of body mass index on perioperative complications and associated risk factors for its occurrence. METHODS: Two groups were compared on the basis of body mass index: group A with body mass index <32 kg/m2 and group B with body mass index ³32 kg/m2. A multivariate analysis was carried out to identify independent predictors for complications. Complications were classified based on the Clavien-Dindo score. RESULTS: A total of 49 patients were included in this study, with 30 in group A and 19 in group B. The groups were compared based on factors, such as age, Charlson Comorbidity Index, surgical techniques used, type and location of hiatal hernia, and length of stay. Findings showed that 70% of patients had complex hiatal hernia. In addition, 14 complications also occurred: 7 pleuropulmonary and 7 requiring reoperation. From the seven reoperated, there were three recurrences, two gastrointestinal fistulas, one diaphragmatic hernia, and one incisional hernia. Complications were similar in both the groups, with type IV hiatal hernia being the only independent predictor. CONCLUSIONS: Body mass index does not affect perioperative complications in anti-reflux surgery and type IV hiatal hernia is an independent predictor of its occurrence.

RESUMO RACIONAL: O impacto do índice de massa corpórea nos resultados da cirurgia de hérnia de hiato é controverso na literatura. OBJETIVOS: avaliar o impacto do índice de massa corpórea nas complicações perioperatórias em pacientes submetidos a cirurgia de hérnia hiatal, e seus possíveis preditores. MÉTODOS: análise retrospectiva 49 pacientes submetidos a tratamento cirúrgico de hérnias hiatais complexas por videolaparoscopia, divididos em dois grupos pelo índice de massa corpórea (grupo A<32kg/m2 - 30 pacientes e grupo B ³32 kg/m2 — 19 pacientes) e comparados quanto suas características e complicações. A análise multivariada foi aplicada para avaliar as variáveis preditoras independentes de complicações. As complicações foram classificadas conforme Clavien Dindo. RESULTADOS: Os grupos foram similares conforme a idade, índice de comorbidade de Charlson, técnica operatória empregada, tipo de hérnia de hiato, área do hiato esofageano, e tempo de internação pós-operatória. Setenta por cento dos pacientes possuíam hérnias de hiato complexas (gigantes ou recidivadas). Catorze complicações foram observadas: 7 pleuro pulmonares e 7 necessitando reoperação, sendo destas 3 recidivas, 2 fístulas digestivas, 1 hérnia diafragmática e 1 hérnia incisional. As complicações foram semelhantes em ambos os grupos, e a hérnia de hiato tipo IV foi o único preditor independente. CONCLUSÕES: O índice de massa corpórea não influencia nos resultados perioperatórios e a hérnia de hiato tipo IV é o único preditor independente de complicações.

Management of acute appendicitis during the COVID-19 pandemic: Views of two Brazilian surgical societies.

Acute appendicitis (AA) is a frequent cause of abdominal pain requiring surgical treatment. During the COVID-19 pandemic, surgical societies considered other therapeutic options due to uncertainties in the evolution of the disease. The purpose of this study is to assess the treatment of AA by members of two Brazilian surgical societies in this period. A common questionnaire was sent in 2020. There were 382 responses. Most surgeons had more than 15 years of profession (68.3%) and treated more than five cases per month (44.8%). About 72.5% would indicate chest CT to investigate COVID-19 in patients with AA. For those patients sustaining uncomplicated AA, without COVID-19, 60.2% would indicate laparoscopic appendectomy (VLA), followed by open appendectomy (OA) (31.7%) and non-operative management (NOM) (1.3%). For those with mild COVID-19, OA was suggested by 51.0%, followed by VLA (29.6%) and NOM (6.0%). For those with severe COVID-19, OA was proposed by 35.3%, followed by NOM (19.9%) and VLA (18.6%). For patients with periappendiceal abscesses, without COVID-19, VLA was suggested by 54.2%, followed by OA (33.2%) and NOM (4.4%). For those with mild COVID-19, OA was proposed in 49.5%, followed by VLA (29.3%) and NOM (8.9%). In those with severe COVID-19, OA was proposed in 36.6%, followed by NOM (25.1%) and VLA (17.3%). This information, based on two recognized Brazilian surgical societies, can help the surgeon to select the best approach individually.

RESUMO A apendicite aguda (AA) é causa frequente de abdome agudo cirúrgico. Durante a pandemia de COVID-19, devido às incertezas na evolução da doença, sociedades consideraram outras opções terapêuticas. Nosso objetivo é descrever o tratamento da AA por membros do CBC e SBAIT neste período. O questionário foi enviado em 2020. Houve 382 respostas. A maioria dos profissionais tinha mais de 15 anos de profissão (68,3%) e atendia mais de cinco casos por mês (44,8%). Cerca de 72,5% realizariam TC de tórax para investigação de COVID-19 em pacientes com AA. Nos com AA não complicada, sem COVID-19, 60,2% optariam pela apendicectomia videolaparoscópica (AVL), seguido de apendicectomia aberta (AAB) (31,7%) e tratamento não operatório (TNO) (1,3%). Nos com COVID-19 leve, AAB foi proposta por 51,0%, seguido da AVL (29,6%) e TNO (6,0%). Nos com COVID-19 grave, a AAB foi proposta por 35,3%, seguido de TNO (19,9%) e AVL (18,6%). Nos com AA complicadas com abscesso, sem COVID-19, AVL foi sugerida por 54,2%, seguida da AAB (33,2%) e TNO (4,4%). Nos com COVID-19 leve, a AAB foi proposta em 49,5%, seguidos da AVL (29,3%) e TNO (8,9%). Nos com COVID-19 grave, a AAB foi proposta em 36,6%, seguido de TNO (25,1%) e AVL (17,3%). Estas são opções de cirurgiões de duas sociedades cirúrgicas reconhecidas e podem auxiliar o colega que está na linha de frente a definir a melhor conduta individualmente.

Organic inflammatory response to reduced preoperative fasting time, with a carbohydrate and protein enriched solution; a randomized trial / La respuesta orgánica inflamatoria en la reducción del tiempo de ayuno preoperatorio con una solución enriquecida con carbohidratos y proteínas; un estudio aleatorizado

Background: this study aims to assess the organic inflammatory response of the video laparoscopic cholecystectomy, with abbreviation of the preoperative fasting to 2h using a carbohydrate and protein enriched solution. Methods: this is a randomized, prospective study with patients divided into the following 2 groups: group A, conventional fasting and group B, 2h abbreviated fasting with oral ingestion of a carbohydrate and protein solution. Serum glucose, insulin, interleukin 1, and TNF-α were mesasured before ingestion of the solution, during induction of anesthesia, and 4 h after the end of surgery. Results: thirty-eight patients completed the study without presenting pulmonary complications associated with bronchoaspiration. The postoperative HOMA-IR variance was greater in group A (p = 0.001). Conclusion: the abbreviation of preoperative fasting for 2 h, using carbohydrate and protein enriched solutions, is safe, reduces insulin resistance, and does not increase the risk of bronchoaspiration (AU)

Introducción: El objetivo de este estudio es la evaluación de la respuesta inflamatoria orgánica a la colecistectomía laparoscópica mediante vídeo con una reducción del tiempo de ayuno preoperatorio a 2h y empleando una solución enriquecida con carbohidratos y proteínas. Métodos: Se trata de un estudio aleatorizado, prospectivo con pacientes divididos en los dos grupos siguientes: grupo A, ayuno convencional y grupo B, ayuno abreviado de 2h con ingesta oral de una solución enriquecida con carbohidratos y proteínas. Antes de la ingesta de la solución, se hicieron mediciones de glucosa sérica, insulina, interleucina 1y TNF-α; también se realizaron mediciones durante la inducción de la anestesia y 4h después de la intervención quirúrgica. Resultados: Treinta y ocho pacientes completaron el estudio sin presentar complicaciones pulmonares relacionadas con el broncoaspirado. La varianza HOMA-IR postoperatoria fue superior en el grupo A (p = 0,001). Conclusión: La reducción del tiempo de ayuno preoperatorio a 2h, empleando soluciones enriquecidas con carbohidratos y proteínas, es segura, reduce la resistencia a la insulina, y no aumenta el riesgo de broncoaspirado (AU)

Duodenojejunostomia látero-lateral: uma alternativa cirúrgica para o tratamento do "dumping" pós gastrectomia / Side to side duodenojejunostomy: a surgical alternative for dumping after gastrectomy

Most patients with partiaI gastrectomy have no postoperative problems. Some of them, however, develop severe nutritional disturbance, particularly those with Bilroth II reconstruction, which can be treated clinically in the majority of the cases. Those with important mal absorptive problems require surgery. In this article we present a technical alternative for those patients who need reintervention over a BII operation. Our technique has the advantage of not touching the duodenum previously sutured.
