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.

MANAGEMENT OF SYMPTOMS RECURRENCE AFTER MYOTOMY FOR ACHALASIA. A PRACTICAL APPROACH.

BACKGROUND: Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases. AIMS: This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy. METHODS: A critical review was performed to gather evidence for a rational approach for managing the recurrence or persistence of achalasia symptoms after myotomy. RESULTS: To properly manage an achalasia patient with significant symptoms after myotomy, such as dysphagia, regurgitation, thoracic pain, and weight loss, it is necessary to classify symptoms, stratify severity, perform appropriate tests, and define a treatment strategy. A systematic differential diagnosis workup is essential to cover the main etiologies of symptoms recurrence or persistence after myotomy. Upper digestive endoscopy and dynamic digital radiography are the main tests that can be applied for investigation. The treatment options include endoscopic dilation, peroral endoscopic myotomy, redo surgery, and esophagectomy, and the decision should be based on the patient's individual characteristics. CONCLUSIONS: A good clinical evaluation and the use of proper tests jointly with a rational assessment, are essential for the management of symptoms recurrence or persistence after achalasia myotomy.

Advanced Cancer-A Bad Consequence of a Missed Follow-Up after ESD in Barrett's Esophagus.

Barrett's esophagus(BE)is a precursor to adenocarcinoma of the esophagogastric transition. Thus, endoscopic surveillance is essential for the early diagnosis of dysplasia and neoplasm, allowing proper therapeutic. However, during the COVID-19 pandemic, surveillance frequently failed. We present a case of a male, caucasian, 65 years old, patient with early adenocarcinoma in BE. Submitted an endoscopic resection, but due to the COVID-19 pandemic patient lost the follow-up endoscopic exams. Returned with a T3N1 adenocarcinoma esophagus in resection area. The present report illustrates the consequences of the failure in follow-up after submucosal resection in COVID-19 pandemic context.

BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT / Posição da Sociedade Brasileira de Hérnia e Parede Abdominal sobre o tratamento de grandes hérnias de hiato

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.

A case report of esophageal leiomyoma in Alport's syndrome treated with robotic-assisted distal myotomy: A surgical technique to avoid esophagectomy.

INTRODUCTION: Alport's syndrome is the most common hereditary nephropathy, characterized by progressive renal failure, sensorineural deafness, and ocular abnormalities. It may rarely coexist with diffuse leiomyomatosis of the digestive tract, respiratory tract, or female genitalia, and in this setting, it is called Alport-leiomyomatosis syndrome. The leiomyomas most commonly affect the esophagus, and the symptoms have early onset. Treatment is usually esophagectomy. CASE PRESENTATION: We report the case of an 8 years-old girl in which we performed a novel strategy of an esophagus-sparing approach with a robotic-assisted myotomy. This conservative approach has never been described in the literature to our knowledge. DISCUSSION: The underpinning rationale was to resolve the patient's symptoms with partial resection of the benign tumor, avoiding an esophagectomy. Although it is likely related to a higher relapsing rate, it is more tolerable by an 8 years-old patient, and was highly effective in resolving her symptoms. CONCLUSION: The video of a successful minimally invasive conservative approach to esophageal leiomyomatosis is presented.

CHARACTERIZATION OF THE PSYCHOLOGICAL TYPOLOGY IN ESOPHAGEAL CANCER PATIENTS.

BACKGROUND: Esophageal cancer is an environment-related disease, and the most important risk factors are alcohol intake and smoking, in addition to gastroesophageal reflux in obese patients. The characterization of the patients' personality can contribute to the perception of how everyone adapts to the social environment and what relationship one can establish with themselves and with others. AIM: The aim of this study was to identify the psychological typology in patients with esophageal cancer. METHODS: The psychological typology of patients was defined using the Typological Assessment Questionnaire. In addition, the aspects of psychological assessment were studied to access the particularities of each patient, especially their reaction to the diagnosis and the meaning attributed to the disease. RESULTS: A total of 90 patients with esophageal cancer, aged over 18 years, who completed high school, and were interviewed at the first medical appointment, were included. The introverted attitude was predominant (83.33%). The most common psychological type was introverted sensation, with feeling as a secondary function (43.3%), and the second most frequent was introverted feeling, with sensation as a secondary function (24.4%). From this psychological assessment, a variety of defensive mechanisms were found to minimize distress. Most patients made use of adaptive defenses in the face of the illness process. CONCLUSION: The identification of the psychological typology allows the most effective assistance in directing the peculiar needs of each patient. In addition, it contributes to the care team to individualize treatments based on specific psychological characteristics.

RESUMO RACIONAL: A acalasia é um distúrbio da motilidade esofágica e a miotomia é uma das técnicas de tratamento mais utilizadas. No entanto, a persistência ou recorrência dos sintomas ocorre em 9 a 20%. OBJETIVOS: Este estudo visa fornecer uma abordagem prática para o manejo da recorrência ou persistência dos sintomas de acalasia após miotomia. MÉTODOS: Foi realizada uma revisão crítica para reunir evidências para uma abordagem racional no manejo da recorrência ou persistência dos sintomas de acalasia após miotomia. RESULTADOS: Para o manejo adequado de um paciente com acalásia com sintomas significativos após miotomia, como disfagia, regurgitação, dor torácica e perda de peso, é necessário classificar os sintomas, estratificar a gravidade, realizar exames adequados e definir uma estratégia de tratamento. Uma investigação diagnóstica diferencial sistemática é essencial para cobrir as principais etiologias de recorrência ou persistência dos sintomas após a miotomia. A endoscopia digestiva alta e a radiografia digital dinâmica são os principais exames que podem ser aplicados para investigação. As opções de tratamento incluem dilatação endoscópica, POEM (miotomia endoscópica oral), remiotomia e esofagectomia, e a decisão deve ser baseada nas características individuais do paciente. CONCLUSÕES: Uma boa avaliação clínica e a utilização de exames adequados, juntamente com uma avaliação racional, são essenciais para o manejo da recorrência ou persistência dos sintomas após miotomia por acalasia.

18F-FDG-PET/CT-measured parameters as potential predictors of residual disease after neoadjuvant chemoradiotherapy in patients with esophageal carcinoma.

Objective: To evaluate the maximum and mean standardized uptake values, together with the metabolic tumor value and the total lesion glycolysis, at the primary tumor site, as determined by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG-PET/CT), performed before and after neoadjuvant chemoradiotherapy (nCRT), as predictors of residual disease (RD) in patients with esophageal cancer. Materials and Methods: The standardized uptake values and the volumetric parameters (metabolic tumor value and total lesion glycolysis) were determined by 18F-FDG-PET/CT to identify RD in 39 patients before and after nCRT for esophageal carcinoma. We used receiver operating characteristic curves to analyze the diagnostic performance of 18F-FDG-PET/CT parameters in the definition of RD. The standard of reference was histopathological analysis of the surgical specimen. Results: Eighteen patients (46%) presented RD after nCRT. Statistically significant areas under the curve (approximately 0.72) for predicting RD were obtained for all four of the variables evaluated after nCRT. Considering the presence of visually detectable uptake (higher than the background level) at the primary tumor site after nCRT as a positive result, we achieved a sensitivity of 94% and a specificity of 48% for the detection of RD. Conclusion: The use of 18F-FDG-PET/CT can facilitate the detection of RD after nCRT in patients with esophageal cancer.

Objetivo: Avaliar os valores máximo e médio de captação padronizada, o valor metabólico do tumor e a glicólise total da lesão do local do tumor primário, medidos no estudo de 18F-FDG-PET/CT realizado antes e depois da quimiorradioterapia neoadjuvante (nQRT) em pacientes com câncer de esôfago, como preditores de doença residual (DR). Materiais e Métodos: Os valores máximo e médio de captação padronizada e os parâmetros volumétricos (valor metabólico do tumor e glicólise total da lesão) da 18F-FDG-PET/CT realizada em 39 pacientes antes e após a nQRT para carcinoma de esôfago foram avaliados para RD. Usamos curvas receiver operating characteristic (ROC) para analisar o desempenho diagnóstico dos parâmetros 18F-FDG-PET/CT na definição de RD. O estudo anatomopatológico foi utilizado como padrão ouro. Resultados: Dezoito pacientes (46%) apresentaram DR após a nQRT. Áreas estatisticamente significativas sob a curva ROC para predizer DR foram obtidas para as quatro variáveis nos estudos realizados após a nQRT, com áreas sob a curva ROC semelhantes em torno de 0,72. Considerando a presença de captação visualmente detectável (captação maior que o background) no local da lesão primária após a nQRT como resultado positivo, teríamos uma sensibilidade de 94% e uma especificidade de 48% para detecção de DR. Conclusão: A 18F-FDG-PET/CT pode ser útil para detectar a presença de doença neoplásica residual no câncer de esôfago após a nQRT.

Prognostic Value of Bone Marrow Uptake Using 18F-FDG PET/CT Scans in Solid Neoplasms.

BACKGROUND: Fluorine-18-fluorodeoxyglucose positron emission tomography/computerized tomography (18F-FDG PET/CT) uptake is known to increase in infective and inflammatory conditions. Systemic inflammation plays a role in oncologic prognosis. Consequently, bone marrow increased uptake in oncology patients could potentially depict the systemic cancer burden. METHODS: A single institute cohort analysis and a systematic review were performed, evaluating the prognostic role of 18F-FDG uptake in the bone marrow in solid neoplasms before treatment. The cohort included 113 esophageal cancer patients (adenocarcinoma or squamous cell carcinoma). The systematic review was based on 18 studies evaluating solid neoplasms, including gynecological, lung, pleura, breast, pancreas, head and neck, esophagus, stomach, colorectal, and anus. RESULTS: Bone marrow 18F-FDG uptake in esophageal cancer was not correlated with staging, pathological response, and survival. High bone marrow uptake was related to advanced staging in colorectal, head and neck, and breast cancer, but not in lung cancer. Bone marrow 18F-FDG uptake was significantly associated with survival rates for lung, head and neck, breast, gastric, colorectal, pancreatic, and gynecological neoplasms but was not significantly associated with survival in pediatric neuroblastoma and esophageal cancer. CONCLUSION: 18F-FDG bone marrow uptake in PET/CT has prognostic value in several solid neoplasms, including lung, gastric, colorectal, head and neck, breast, pancreas, and gynecological cancers. However, future studies are still needed to define the role of bone marrow role in cancer prognostication.

18F-FDG-PET/CT-measured parameters as potential predictors of residual disease after neoadjuvant chemoradiotherapy in patients with esophageal carcinoma / 18F-FDG-PET/CT após quimiorradioterapia neoadjuvante em pacientes com carcinoma de esôfago como potencial preditor de doença residual

Tumor size predicts worse prognosis in esophagogastric junction adenocarcinoma.

Adenocarcinoma of the esophagogastric junction (AEGJ) has an increasing incidence and is associated with limited overall survival. Several studies have tried to identify prognostic factors for AEGJ, although few have described relationships between prognosis and the tumor's size or anatomical location. Thus, this retrospective study evaluated 188 patients with resected locally advanced AEGJ. Tumor location was determined using upper endoscopy, and the following groups were created: E&E + EGJ (distal esophagus, esophagogastric junction, and distal esophagus), EGJ (esophagogastric junction), EGJ + G (esophagogastric junction and proximal stomach), G (proximal stomach), and E + EGJ + G (esophagus to the proximal stomach, including the esophagogastric junction). Other variables of interest were tumor size and differentiation, TNM stage, comorbidities, surgery type, and survival outcomes. Among 188 patients included, 163 were men (86.7%), and the mean age was 64.9 years. Forty-eight (25.6%) patients underwent total gastrectomy and distal esophagectomy, while 140 (74.4%) subtotal esophagectomy with proximal gastrectomy. Presence of comorbidities, tumor size, angiolymphatic and perineural invasion, and pTNM status were different between groups according to tumor location. The mean follow-up period was 47.4 months. The disease-free survival (DFS) rates were as follows: 72.7% (G), 68.0% (E&E + EGJ), 63.4% (EGJ), 57.1% (EGJ + G), and 44.4% (E + EGJ + G), while the overall survival (OS) rates were 81.0% (EGJ + G), 78.8% (G), 64.0% (E&E + EGJ), 54.9% (EGJ), and 48.1% (E + EGJ + G). Multivariate analysis revealed that tumor size of < 5 cm, and tumor location G subgroups were associated with better DFS. High histological grade and advanced pT status were independent factors related to worse OS. In conclusion, the prognosis of AEGJ may be preoperatively predicted by a tumor size of ≥ 5 cm and its anatomical location.

Evaluation of the 18F-FDG-PET/CT uptake association with pathological and immunohistochemistry features in esophagogastric adenocarcinoma.

BACKGROUND: The present study aimed to analyze the association between 18F-fluorodeoxyglucose (FDG) uptake and histologic panel in esophagogastric adenocarcinoma. METHODS: We retrospectively enrolled 26 patients with histologically confirmed esophageal, gastroesophageal junction and gastric adenocarcinoma that have been submitted to pretreatment FDG-PET/CT. We collected the cancer tissue sample of each patient and performed immunohistochemical analyses of the glucose transport protein 1 (GLUT-1), Ki-67, cysteine aspartate-specific proteinases (Caspase)-3 and hexokinase-1, and evaluated the association of these parameters with FDG uptake. The FDG uptake was measured by tumor standardized uptake value (SUV), metabolic tumor volume (MTV), and Total Lesion Glycolysis (TLG). Besides, we analyzed the association of FDG uptake and tumor location, Lauren's histologic subtype, grade of cellular differentiation and intratumoral inflammatory infiltrate. RESULTS: We found a positive association between GLUT-1 with SUV and TLG, Caspase-3 and SUV and inflammation grade with SUV. CONCLUSION: Tumor inflammation infiltrate, GLUT-1 and Caspase-3 correlated with 18F-FDG uptake in PET/CT in esophagogastric adenocarcinoma. These findings may help understand the pathologic PET/CT significance in cancer. Understanding the meaning of the 18F-FDG uptake in the field of tumor histologic and immunohistochemistry features is essential to allow the evolution of PET/CT application in esophageal and gastric carcinomas.

Long-term results of an endoscopic screening program for superficial esophageal cancer in patients with head and neck squamous cell carcinoma.

Background and study aims Patients with head and neck squamous cell carcinoma (HNSCC) are at risk of a second primary tumor in the gastrointestinal tract, most commonly in the esophagus. Screening these patients for esophageal carcinoma may help detect asymptomatic dysplasia and early cancer, thus allowing curative treatment and more prolonged survival, but the impact of endoscopic screening remains uncertain. Here we aimed to describe the long-term results of an esophageal SCC screening program in patients with head and neck cancer in terms of prevalence, associated risk factors, and survival. Patients and methods We performed an observational study of a prospectively collected database including patients with HNSCC who had undergone high-definition endoscopy with chromoscopy between 2010 and 2018 at a Brazilian tertiary academic center. Results The study included 1,888 patients. The esophageal SCC prevalence was 7.9 %, with the majority (77.8 %) being superficial lesions. Significant risk factors for esophageal high-grade dysplasia (HGD) and invasive cancer included tumors of the oral cavity and oropharynx and the presence of low-grade dysplasia (LGD). Overall survival (OS) was significantly shorter among patients in whom esophageal cancer was diagnosed at an advanced stage ( P  < .001). OS did not significantly differ between patients with HGD and early esophageal cancer versus those without esophageal cancer ( P  = .210) Conclusions Endoscopic screening for superficial esophageal neoplasia in patients with HNSCC improves esophageal cancer detection. Screening could potentially benefit patients with primary cancer located at the oropharynx or oral cavity. In addition, the detection of esophageal LGD indicates a need for endoscopic surveillance.

Laparoscopic transhiatal esophagectomy in esophageal cancer patients with high-risk post-operative complications.

Surgical treatment of esophageal cancer is challenging, due to considerable morbidity, especially in high surgical risk patients. While transhiatal esophagectomy leads to good oncological outcomes and reduced postoperative complications, less invasive techniques might further improve outcomes. Our goal was to compare results of laparoscopic transhiatal esophagectomy (LTE) with open transhiatal esophagectomy (OTE) in esophageal cancer patients at high surgical risk. From 2014 to 2020, 128 patients were identified. Seventy received OTE while 51 received LTE. After propensity score matching (1:1), postoperative complications, analysis of overall and disease-free survival, and survival-related prognostic factors were assessed in two groups of 48 patients. Ninety-one (77%) patients were men with a mean age of 65 ± 10.3 years. Those who underwent OTE experienced more clinical and surgical complications. In LTE patients, the number of mean resected lymph nodes was 25.9, and in patients who had OTE, it was 17.4 (P < 0.001). Overall survival was 56.0% in the LTE group and 33.6% (P = 0.023) in the OTE group. In multivariable analysis of overall survival, open surgery and incomplete pathological response were seen as worse negative factors. In multivariable analysis, metastatic lymph nodes, incomplete pathologic response, surgical complications, and a Charlson's index > 2 (P = 0.014) were associated with poor prognosis. Both surgical methods are safe with similar morbidity and mortality; however, LTE was associated with fewer complications, a higher number of resected lymph nodes, better overall survival, and more prognostic factors related to global and disease-free overall survival in high-risk patients.

Characterization of the psychological typology in esophageal cancer patients / Caracterização da tipologia psicológica em pacientes com câncer de esôfago

ABSTRACT BACKGROUND: Esophageal cancer is an environment-related disease, and the most important risk factors are alcohol intake and smoking, in addition to gastroesophageal reflux in obese patients. The characterization of the patients' personality can contribute to the perception of how everyone adapts to the social environment and what relationship one can establish with themselves and with others.

RESUMO RACIONAL: O câncer de esôfago é uma doença relacionada ao meio ambiente, e os fatores de risco mais importantes são a ingestão de álcool e tabagismo, além do refluxo gastroesofágico em pacientes obesos. A caracterização da personalidade do paciente contribui para a percepção de como cada indivíduo se adapta ao meio social e que relação pode estabelecer consigo mesmo e com os outros. OBJETIVO: Identificar a tipologia psicológica em pacientes com câncer de esôfago. MÉTODOS: Definiu-se a tipologia psicológica utilizando o Questionário de Avaliação Tipológica. Estudaram-se os aspectos da avaliação psicológica para acessar as particularidades de cada um dos pacientes, principalmente no que diz respeito à sua reação ao diagnóstico e ao significado atribuído à doença. RESULTADOS: Foram incluídos noventa pacientes, com mais de 18 anos, ensino médio completo, diagnóstico de câncer de esôfago e que foram entrevistados na primeira consulta médica. A atitude introvertida foi a preponderante (83,33%). O tipo psicológico mais comum foi introvertido — sensação, tendo o sentimento como função secundária (43,3%), e introvertido — sentimento com sensação como função secundária foi o segundo tipo mais frequente (24,4%). A partir dessa avaliação psicológica, encontrou-se uma variedade de mecanismos defensivos para minimizar a angústia. A maioria dos pacientes fez uso de defesas adaptativas diante do processo de adoecimento. CONCLUSÕES: A identificação da tipologia psicológica permite o auxílio mais eficaz no direcionamento das necessidades peculiares de cada indivíduo. Além disso, contribui com a equipe de atendimento a fim de individualizar os tratamentos com base nas características psicológicas específicas.

Surgical management of esophageal stenosis due to ingestion of corrosive substances.

BACKGROUND: Corrosive ingestion is a significant challenge for healthcare systems. Limited data are available regarding the best treatments, and there remains a lack of consensus about the optimal surgical approach and its outcomes. This study aims to review the current literature and show a single institution's experience regarding the surgical treatment of esophageal stenosis due to corrosive substance ingestion. METHODS: A retrospective review that accounted for demographics, psychiatric profiles, surgical procedures, and outcomes was performed. A systematic review of the literature was performed using PubMed. RESULTS: In total, 27 surgical procedures for esophageal stenosis due to corrosive substance ingestion were performed from 2010 to 2019. Depression and drug abuse were diagnosed in 30% and 22% of the included patients, respectively. Esophagectomies and esophageal bypasses were performed in 13 and 14 patients, respectively. No 30-day mortality was recorded. CONCLUSION: Surgical intervention either by esophagectomy or esophageal bypass results in durable relief from dysphagia. However, successful clinical outcomes depend on a high-quality multidisciplinary network of esophageal and thoracic surgeons, intensivists, psychologists, psychiatrists, and nutritional teams.

Supercharged cervical anastomosis for esophagectomy and gastric pull-up.

OBJECTIVE: Esophagectomy has high rates of morbidity and mortality. Anastomotic leakage is the most frequent complication and is likely caused by diminished anastomotic perfusion. Supercharged microvascular anastomosis has previously been performed in select patients to supplement the blood supply to the graft and anastomosis after esophagectomy. This study aimed to evaluate complications that may arise after performing the supercharged cervical anastomosis for esophagectomy procedure. METHODS: This prospective comparative study evaluated patients who underwent esophagectomy with gastric reconstruction and cervical anastomosis for locally advanced esophageal carcinoma. Patients were divided into group 1, in which conventional cervical anastomosis was performed, and group 2, in which cervical anastomosis using the supercharged cervical anastomosis for esophagectomy procedure was performed. The anastomotic perfusion areas in group 2 patients were evaluated using indocyanine and the SPY device (Novadaq Technologies, Inc, Toronto, Ontario, Canada) before and after supercharged cervical anastomosis for esophagectomy. Postesophagectomy complications were also recorded. RESULTS: The study enrolled 80 patients, which included 62 (77.5%) men, mean age 64.3 years. Groups 1 and 2 comprised 55 patients and 25 patients, respectively. Leakage occurred in 10.5% and 0% of patients in groups 1 and 2, respectively (P = .169), whereas the corresponding anastomotic stricture rates were 14.5% and 4%, respectively (P = .260). Perfusion analyses showed a 26.5% improvement in the anastomotic area after venous anastomosis and a 34.6% improvement after arterial and venous anastomosis. CONCLUSIONS: The supercharged cervical anastomosis for esophagectomy procedure may reduce the occurrence of anastomotic leakage and improve perfusion in the anastomotic area via vein and arterial microanastomoses.

Prognostic value of 18F-fluorodeoxyglucose PET/computed tomography metabolic parameters measured in the primary tumor and suspicious lymph nodes before neoadjuvant therapy in patients with esophageal carcinoma.

BACKGROUND: 18F-fluorodeoxyglucose PET/computed tomography (18F-FDG PET/CT) metabolic parameters are prognostic indicators in several neoplasms. This study aimed to evaluate the prognostic value of the maximum and average standardized uptake value (SUVmax and SUVavg), metabolic tumor value (MTV), and total lesion glycolysis (TLG) measured in the primary tumor and suspicious lymph nodes preneoadjuvant therapy in patients submitted to surgical resection for esophageal cancer. METHODS: A cohort of 113 patients with esophageal cancer who performed 18F-FDG PET/CT preneoadjuvant therapy was assessed. The association of the SUV, MTV, and TLG measured in the primary tumor and in the suspicious lymph nodes with the overall survival was assessed. It was also analyzed other potentially confounding variables such as age, sex, clinical stage, and histologic subtype. The analyses were performed using Kaplan-Meier curve, log-rank test, and Cox regression. RESULTS: The univariate analyses showed that the MTV and TLG in the primary tumor, the SUV in the suspicious lymph nodes, the age, the histologic subtype, and the clinical stage were associated with survival after surgery (P ≤ 0.05). In the Cox regression multivariate analyses, all variables identified in the univariate analyses but the clinical stage were associated with survival after surgery (P ≤ 0.05). CONCLUSION: In esophageal cancer patients, some of the 18F-FDG PET/CT metabolic parameters measured in the primary tumor and in the suspicious lymph nodes before the neoadjuvant therapy are independent indicators of overall survival and appear to be more important than the clinical stage in the prognostic definition of this group of patients.
