RESUMEN
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.

PURPOSES: Tumor regression grade (TRG) of the primary tumor after neoadjuvant therapy is one of the most sensitive prognostic factors among patients with locally advanced esophageal cancer, although no TRG system is fully accepted. The Ryan score was proposed in 2005 to evaluate TRG in rectal cancer and could be adaptable for pathological evaluation of esophageal cancer. The objective of this study is to evaluate the prognostic value of the Ryan score for esophageal cancer in the setting of trimodal therapy. METHODS: We performed a retrospective cohort study in which patients with locally advanced esophageal cancer, submitted to neoadjuvant therapy followed by surgical resection, were selected. One hundred thirty-four patients were selected. All tissue specimens were assessed as per the TRG system proposed by Ryan et al. Survival curves were assessed by the Kaplan-Meier method and log-rank test. Chi-square test or likelihood-ratio test was used for absolute and relative variables. Kruskal-Wallis and analysis of variance tests were used to assess significant differences on a continuous dependent variable by a categorical independent variable. RESULTS: Of the 134 included patients, 94 (70.1%) had squamous cell carcinoma, and 40 (29.9%) adenocarcinoma. Ryan score was correlated with histological type (p < 0.001), and clinical (p = 0.044) and pathological (p < 0.001) staging. Mean follow-up was 31.1 months. Multivariate analysis showed that Ryan score can safely predict survival, and systemic and lymphatic recurrence (p < 0.05). CONCLUSIONS: Ryan score is an effective system to evaluate TRG and can predict risk for lymph node or distant metastasis, overall survival, and disease-free survival.

BACKGROUND: Inflammation status plays an important role in the natural history of malignancy. Consequently, hematological markers of systemic inflammation may predict prognosis in neoplasms. This study evaluated the value of cellular blood components changes during neoadjuvant chemoradiotherapy followed by esophagectomy for cancer in predicting prognosis. METHODS: A cohort of 149 patients was analyzed. Cellular components of blood were assessed before neoadjuvant therapy (A); before surgery (B); and 3 to 5 months after surgery (C); for the following outcomes: pathological response, overall survival (OS), and disease-free survival (DFS). Univariate and multivariate Cox regression models were applied to evaluate the independent prognostic significance of blood count variables. RESULTS: Low hematocrit (Ht) (C) (HR, 0.85; 95% CI, 0.79-0.92) and high neutrophil-to-lymphocyte ratio (NLR) (C) (HR, 1.07; 95% CI, 1.07-1.10) were related to poor OS. Low Hb (C) (HR, 0.72; 95% CI, 0.58-0.88), red cell distribution width (RDW) (C-A) (HR, 1.16; 95% CI, 1.02-1.31), and NLR (C-A) (1.06; 95% CI, 1.03-1.09) were related to poor DFS. RDW (B-A) (HR, 1.15; 95% CI, 1.08-1.22), RDW (C) (HR, 1.12; 95% CI, 1.04-1.2), NLR (C) (HR, 1.12; 95% CI, 1.08-1.17) were related to systemic recurrence. CONCLUSION: Variables of routine blood count are easily assessable and their changes throughout trimodal therapy for esophageal carcinoma provide important information for cancer patient's prognosis.

The most common sites of metastases in renal cell carcinoma (RCC) are lung and bone. However, unusual sites, including the stomach, are characteristic of RCC.This article presents a case of a metastatic RCC (lung and liver) with a symptomatic gastric metastasis treated by a laparoscopic wedge resection (LWR).A 66-year-old woman, diagnosed with RCC underwent a right nephrectomy. During her follow-up, an upper gastrointestinal (GI) endoscopy showed an ulcerated lesion at the stomach. A biopsy of the specimen revealed metastatic RCC. The patient underwent a palliative LWR and was discharged home 8 days after surgery.Therefore, LWR is a relatively simple technique with the advantages of minimal invasive access in the treatment of palliative cases.

Primary malignant melanoma of the esophagus is an uncommon tumor, with approximately 300 cases having been reported thus far. The purpose of this study was to describe a case of a 60 year-old man with a 10 month history of progressive dysphagia and thoracic pain, the investigations of which led to a diagnosis of primary malignant melanoma of the esophagus. The patient underwent a transhiatal esophagectomy with subcarinal lymphadenectomy, and isoperistaltic gastric tube replacement of the esophagus. Nine months after surgery, he developed ischemic colitis, and metastasis in the mesentery was diagnosed. His disease progressed and he died one year after the esophagectomy. A review of the literature was performed.

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.
RESUMEN
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.

Laparoscopic Heller myotomy is currently considered the standard definitive treatment of achalasia. With the advancements in technology, robotic Heller myotomy has emerged as an alternative approach to traditional laparoscopy due to three-dimensional (3D) visualization, fine motor control, and improved ergonomics provided by the robot. Although there is a lack of randomized controlled trials, robotic-assisted Heller myotomy seems to be associated with lower rates of intraoperative perforations compared to the laparoscopic approach. A robotic approach may also improve surgical outcomes by providing a more complete myotomy. Here, we describe the detailed steps of robotic myotomy and partial fundoplication for achalasia.

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.

BACKGROUND: The enzyme methylenetetrahydrofolate reductase is engaged in DNA synthesis through folate metabolism. Inhibiting the activity of this enzyme increases the susceptibility to mutations, and damage and aberrant DNA methylation, which alters the gene expression of tumor suppressors and proto-oncogenes, potential risk factors for esophageal cancer. AIMS: This study aimed to investigate the association between methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and susceptibility to esophageal cancer, by assessing the distribution of genotypes and haplotypes between cases and controls, as well as to investigate the association of polymorphisms with clinical and epidemiological characteristics and survival. METHODS: A total of 109 esophageal cancer patients who underwent esophagectomy were evaluated, while 102 subjects constitute the control group. Genomic DNA was isolated from the peripheral blood buffy coat followed by amplification by polymerase chain reaction and real-time analysis. Logistic regression was used to assess associations between polymorphisms and the risk of developing esophageal cancer. RESULTS: There was no association for methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and haplotypes, with esophageal cancer susceptibility. Esophageal cancer patients carrying methylenetetrahydrofolate reductase 677TT polymorphism had higher risk of death from the disease. For polymorphic homozygote TT genotype, the risk of death significantly increased compared to wild-type genotype methylenetetrahydrofolate reductase 677CC (reference) cases (p=0.045; RR=2.22, 95%CI 1.02-4.83). CONCLUSIONS: There was no association between methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and esophageal cancer susceptibility risk. Polymorphic homozygote genotype methylenetetrahydrofolate reductase 677TT was associated with higher risk of death after surgical treatment for esophageal cancer.

BACKGROUND: Obesity is a chronic and multifactorial disease with a variety of potential treatment options available. Currently, there are several multidisciplinary therapeutic options for its management, including conservative, endoscopic, and surgical treatment. AIM: To clarify indications, technical aspects, and outcomes of bariatric endoscopy. METHODS: Narrative review of current literature based on electronic databases including MEDLINE (PubMed), Cochrane Library, and SciELO. RESULTS: Bariatric endoscopy is in constant development and comprises primary and revisional treatment options as well as management of surgical complications. Various devices act upon different mechanisms of action, which may be individualized to each patient. Despite favorable results for the endoscopic treatment of obesity, prospective randomized studies with long-term follow-up are required to fully validate primary and revisional endoscopic therapies. Regarding the management of bariatric surgery complications, endoscopic therapy may be considered the procedure of choice in a variety of situations. Still, as there is no standardized algorithm, local experience should be considered in decision-making. CONCLUSION: The treatment of patients with obesity is complex, and a multidisciplinary approach is essential. Bariatric endoscopy has shown impressive results both in the treatment of obesity and its surgical complications, and therefore, must be part of the armamentarium in the fight against this disease.
RESUMEN
This Delphi exercise aimed to gather consensus surrounding risk factors, diagnosis, and management of chyle leaks after esophagectomy and to develop recommendations for clinical practice. Background: Chyle leaks following esophagectomy for malignancy are uncommon. Although they are associated with increased morbidity and mortality, diagnosis and management of these patients remain controversial and a challenge globally. Methods: This was a modified Delphi exercise was delivered to clinicians across the oesophagogastric anastomosis collaborative. A 5-staged iterative process was used to gather consensus on clinical practice, including a scoping systematic review (stage 1), 2 rounds of anonymous electronic voting (stages 2 and 3), data-based analysis (stage 4), and guideline and consensus development (stage 5). Stratified analyses were performed by surgeon specialty and surgeon volume. Results: In stage 1, the steering committee proposed areas of uncertainty across 5 domains: risk factors, intraoperative techniques, and postoperative management (ie, diagnosis, severity, and treatment). In stages 2 and 3, 275 and 250 respondents respectively participated in online voting. Consensus was achieved on intraoperative thoracic duct ligation, postoperative diagnosis by milky chest drain output and biochemical testing with triglycerides and chylomicrons, assessing severity with volume of chest drain over 24 hours and a step-up approach in the management of chyle leaks. Stratified analyses demonstrated consistent results. In stage 4, data from the Oesophagogastric Anastomosis Audit demonstrated that chyle leaks occurred in 5.4% (122/2247). Increasing chyle leak grades were associated with higher rates of pulmonary complications, return to theater, prolonged length of stay, and 90-day mortality. In stage 5, 41 surgeons developed a set of recommendations in the intraoperative techniques, diagnosis, and management of chyle leaks. Conclusions: Several areas of consensus were reached surrounding diagnosis and management of chyle leaks following esophagectomy for malignancy. Guidance in clinical practice through adaptation of recommendations from this consensus may help in the prevention of, timely diagnosis, and management of chyle leaks.
RESUMEN
Esophagectomy remains the preferred option to achieve curative treatment in advanced esophageal cancer, but the choice of surgical approach remains controversial. A transthoracic approach may improve lymph node dissection, but it has considerable morbidity and respiratory complications. Transhiatal access has been demonstrated as an efficient means of minimizing post-operative complications. Minimally invasive transhiatal esophagectomy may reduce operative trauma and morbidity as well as enhance postoperative recovery with no compromise in cancer recurrence or survival. Nevertheless, it has a technical limitation in terms of cervical esophagus dissection. Thus, a low-cost single-port device was developed to complete upper mediastinal dissection by a transcervical approach during minimally invasive transhiatal esophagectomy. This device uses a nasogastric tube, a number-eight sterile glove, a sterile sponge, and 3 permanent 5-mm trocars. The step-by-step process of transhiatal esophagectomy and the development of this device are described. This technique allows for the dissection of the upper mediastinum, as well as the esophagus over the aortic arch and behind the superior portion of the trachea. The harvesting of lymph nodes along the left recurrent laryngeal nerve and paratracheals was improved.

OBJECTIVE: To evaluate telephone monitoring for symptoms, quality of life, distress, admissions to the emergency center and the satisfaction of cancer patients undergoing esophagectomy and gastrectomy. METHOD: Randomized controlled study in two groups, carried out at the Cancer Institute of the State of Sao Paulo; the intervention group received telephone monitoring for four moments after the surgery, while the control group received only institutional care. RESULTS: Of the 81 patients evaluated, the domain most affected by quality of life was social relationships domain. Distress had no significant difference between groups and moments. In both groups, admissions to the emergency center were similar (p=0.539). Pain was the most reported symptom in telephone monitoring. There was statistical significance regarding patient satisfaction with monitoring (p=0.002). CONCLUSION: Telephone monitoring provided greater patient satisfaction in the intervention group, demonstrating the real impact of this process on the care of cancer patients.

BACKGROUND: Thoracoscopic esophagectomy is related to an extended lymphadenectomy, and a high number of retrieved lymph nodes, compared to the transhiatal approach; however, its association with an improvement in overall survival (OS) is debatable. AIM: To compare thoracoscopic esophagectomy with transhiatal esophagectomy in patients with adenocarcinoma of the esophagogastric junction (AEGJ) in terms of survival, number of lymph nodes, and complications. METHODS: In total, 147 patients with AEGJ were selected retrospectively from 2002 to 2019, and divided into Group A for thoracoscopic esophagectomy, and group B for transhiatal esophagectomy. OS, disease-free survival, postoperative complications, and number of nodes, were similarly evaluated. RESULTS: One hundred and thirty (88%) were male; the mean age was 64 years. Group A had a mean age of 61.1 years and group B 65.7 years (P = 0.009). Concerning the extent of lymphadenectomy, group A showed a higher number of retrieved lymph nodes (mean of 31.89 ± 8.2 vs 20.73 ± 7; P < 0.001), with more perioperative complications, such as hoarseness, surgical site infections, and respiratory complications. Although both groups had similar OS rates, subgroup analysis showed better survival of transthoracic esophagectomy in patients with earlier diseases. CONCLUSION: Both methods are safe, having similar morbidity and mortality rates. Transthoracic thoracoscopic esophagectomy allows a more extensive resection of the lymph nodes and may have better oncological outcomes during earlier stages of the disease. Prospective studies are warranted to better evaluate these findings.
RESUMEN
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.

INTRODUCTION AND IMPORTANCE: Esophagectomy for esophageal cancer is one of the most challenging surgical procedures, with high rates of morbidity, especially from respiratory complications. SARS-COVID19 represents a health threat nowadays. Peri-operative SARS-COVID19 infection after esophagectomy might negatively affect the postoperative outcomes. The use of tocilizumab as an alternative to reduce the inflammatory response in SARS-COVID19 is an option that has not been described in the literature after esophagectomy. CASE PRESENTATION: A SARS-COVID19-vaccinated (CORONAVAC) 73-year-old man with pulmonary emphysema, coronary artery disease, previous asymptomatic pulmonary embolism, and adenocarcinoma of the esophagogastric junction tumor was submitted to laparoscopic transhiatal esophagectomy (ypT2N0M0) after perioperative neoadjuvant chemotherapy. He was also infected with SARS-COVID19, confirmed by PCR test at the 14th postoperative day. During follow-up, mild hypoxemia persisted without evidence of infection except for SARS-COVID19, and a high-flow cannula was required to maintain oxygenation. Tocilizumab was administered following high parameters of a high-flow cannula, and invasive mechanical ventilation was avoided. DISCUSSION: Besides of the risk of secondary infection, after administration of tocilizumab, the parameters of oxygen supplementation were systematically reduced, and he stayed in the ICU for seven days. He was discharged from the ward six days later. He developed late cervical anastomotic leakage, which was treated with conservative therapy. CONCLUSION: Although the patient had high-risk comorbidities, esophagectomy, and SARS-COVID19 infection, the use of tocilizumab was safe and improved the pulmonary recovery.
RESUMEN
INTRODUCTION: Adenocarcinoma of the esophagogastric junction (AEGJ) represents a poor prognostic tumor. We evaluated the recurrence pattern and risk factors associated with recurrence in patients undergoing surgical resection by AEJG. METHODS: Recurrences were categorized as locoregional, peritoneal, or distant. These three recurrence groups and a non-recurrence group were compared, and overall survival (OS) and disease-free survival (DFS) for each one was obtained. RESULTS: We analyzed 188 patients with curative surgical treatment. Recurrence was observed in 72 (38.3%) patients. Locoregional recurrence was observed in 17 (23.6%); 20 (27.8%) peritoneal recurrence and 35 (48.6%) distant metastasis. DFS was 9, 5, and 8 months, and OS was 21.8, 13.2, and 20.8, respectively. Tumors larger than 5 cm are risk factors for peritoneal recurrence (OR:2.88, p = 0.012). Positive lymph nodes were related to distant metastasis (OR:9.15, p = 0.040), and lymphatic invasion for locoregional recurrence (OR:3.81, p = 0.028). CONCLUSION: AEGJ is associated with high rates of early recurrence.

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.
