RESUMO
Barrett's oesophagus is the only known precursor to oesophageal adenocarcinoma, a cancer with very poor prognosis. The main risk factors for Barrett's oesophagus are a history of gastro-oesophageal acid reflux symptoms and obesity. Men, smokers and those with a family history are also at increased risk. Progression from Barrett's oesophagus to cancer occurs via an intermediate stage, known as dysplasia. However, dysplasia and early cancer usually develop without any clinical signs, often in individuals whose symptoms are well controlled by acid suppressant medications; therefore, endoscopic surveillance is recommended to allow for early diagnosis and timely clinical intervention. Individuals with Barrett's oesophagus need to be fully informed about the implications of this diagnosis and the benefits and risks of monitoring strategies. Pharmacological treatments are recommended for control of symptoms, but not for chemoprevention. Dysplasia and stage 1 oesophageal adenocarcinoma have excellent prognoses, since they can be cured with endoscopic or surgical therapies. Endoscopic resection is the most accurate staging technique for early Barrett's-related oesophageal adenocarcinoma. Endoscopic ablation is effective and indicated to eradicate Barrett's oesophagus in patients with dysplasia. Future research should focus on improved accuracy for dysplasia detection via new technologies and providing more robust evidence to support pathways for follow-up and treatment.

OBJECTIVE: To evaluate prognostic differences between minimally invasive esophagectomy (MIE) and open esophagectomy (OE) in patients with surgery after a prolonged interval (>12 wk) following chemoradiotherapy (CRT). BACKGROUND: Previously, we established that a prolonged interval after CRT prior to esophagectomy was associated with poorer long-term survival. METHODS: This was an international multi-center cohort study involving seventeen tertiary centers, including patients who received CRT followed by surgery between 2010-2020. Patients undergoing MIE were defined as thoracoscopic and laparoscopic approach. RESULTS: 428 patients (145 MIE and 283 OE) had surgery between 12 weeks and two years after CRT. Significant differences were observed in ASA grade, radiation dose, clinical T stage, and histological subtype. There were no significant differences between the groups in age, sex, BMI, pathological T or N stage, resection margin status, tumor location, surgical technique, or 90-day mortality. Survival analysis showed MIE was associated with improved survival in univariate (P=0.014), multivariate analysis after adjustment for smoking, T and N stage, and histology (HR=1.69; 95% CI 1.14 to 2.5) and propensity matched analysis (P=0.02). Further subgroup analyses by radiation dose and interval after CRT showed survival advantage for MIE, in 40-50Gy dose groups (HR=1.9; 95% CI 1.2 to 3.0), and in patients having surgery within six months of CRT (HR=1.6; 95% CI 1.1 to 2.2). CONCLUSION: MIE was associated with an improved overall survival compared to OE in patients with a prolonged interval from CRT to surgery. The mechanism for this observed improvement in survival remains unknown, with potential hypotheses including a reduction in complications and improved functional recovery after MIE.
RESUMO
BACKGROUND: Personalising management of primary oesophageal adenocarcinoma requires better risk stratification. Lack of independent validation of proposed imaging biomarkers has hampered clinical translation. We aimed to prospectively validate previously identified prognostic grey-level co-occurrence matrix (GLCM) CT features for 3-year overall survival. METHODS: Following ethical approval, clinical and contrast-enhanced CT data were acquired from participants from five institutions. Data from three institutions were used for training and two for testing. Survival classifiers were modelled on prespecified variables ('Clinical' model: age, clinical T-stage, clinical N-stage; 'ClinVol' model: clinical features + CT tumour volume; 'ClinRad' model: ClinVol features + GLCM_Correlation and GLCM_Contrast). To reflect current clinical practice, baseline stage was also modelled as a univariate predictor ('Stage'). Discrimination was assessed by area under the receiver operating curve (AUC) analysis; calibration by Brier scores; and clinical relevance by thresholding risk scores to achieve 90% sensitivity for 3-year mortality. RESULTS: A total of 162 participants were included (144 male; median 67 years [IQR 59, 72]; training, 95 participants; testing, 67 participants). Median survival was 998 days [IQR 486, 1594]. The ClinRad model yielded the greatest test discrimination (AUC, 0.68 [95% CI 0.54, 0.81]) that outperformed Stage (ΔAUC, 0.12 [95% CI 0.01, 0.23]; p = .04). The Clinical and ClinVol models yielded comparable test discrimination (AUC, 0.66 [95% CI 0.51, 0.80] vs. 0.65 [95% CI 0.50, 0.79]; p > .05). Test sensitivity of 90% was achieved by ClinRad and Stage models only. CONCLUSIONS: Compared to Stage, multivariable models of prespecified clinical and radiomic variables yielded improved prediction of 3-year overall survival. CLINICAL RELEVANCE STATEMENT: Previously identified radiomic features are prognostic but may not substantially improve risk stratification on their own. KEY POINTS: ⢠Better risk stratification is needed in primary oesophageal cancer to personalise management. ⢠Previously identified CT features-GLCM_Correlation and GLCM_Contrast-contain incremental prognostic information to age and clinical stage. ⢠Compared to staging, multivariable clinicoradiomic models improve discrimination of 3-year overall survival.
RESUMO
OBJECTIVE: The brain arteriovenous malformation (BAVM) nidus compactness score (CS), determined on angiography, predicts BAVM recurrence after surgical resection among children with sporadic BAVMs. We measured the angiographic CS for BAVMs among children with hereditary hemorrhagic telangiectasia (HHT) to determine CS characteristics in this population. METHODS: A pediatric interventional neuroradiologist reviewed angiograms to determine the CS of BAVMs in children with HHT recruited to the BVMC. CS is based on overall nidus and perinidal anomalous vessel compactness. CS categories included 1 = diffuse nidus, 2 = intermediate nidus, and 3 = compact nidus. RESULTS: Forty-eight of 78 children (61.5%) with HHT and brain vascular malformations had a conventional angiogram; 47 (97.9%) angiograms were available. Fifty-four BAVMs were identified in 40 of these 47 children (85.1%). Of 54 BAVMs in children with HHT, CS was 1 in 7 (13%), 2 in 29 (53.7%), and 3 in 18 BAVMs (33.3%) compared with CS of 1 in six (26.1%), 2 in 15 (65.2%), and 3 in 2 BAVMs (8.7%) among 23 previously reported children with sporadic BAVMs, p = 0.045 (Fisher's exact). Seven children with HHT had intracranial hemorrhage: 4 had CS = 3, 1 had CS = 2, and 2 had CS = 1. CONCLUSIONS: A range of CSs exists across HHT BAVMs, suggesting it may be an angiographic measure of interest for future studies of BAVM recurrence and hemorrhage risk. Children with HHT may have more compact niduses compared to children with sporadic BAVMs. Additional research should determine whether CS affects hemorrhage risk or post-surgical recurrence risk in HHT-associated BAVMs, which could be used to direct BAVM treatment.

OBJECTIVE: To identify prognostic factors associated with 90-day mortality in patients with oesophageal perforation (OP), and characterize the specific timeline from presentation to intervention, and its relation to mortality. BACKGROUND: OP is a rare gastro-intestinal surgical emergency with a high mortality rate. However, there is no updated evidence on its outcomes in the context of centralized esophago-gastric services; updated consensus guidelines; and novel non-surgical treatment strategies. METHODS: A multi-center, prospective cohort study involving eight high-volume esophago-gastric centers (January 2016 to December 2020) was undertaken. The primary outcome measure was 90-day mortality. Secondary measures included length of hospital and ICU stay, and complications requiring re-intervention or re-admission. Mortality model training was performed using random forest, support-vector machines, and logistic regression with and without elastic net regularisation. Chronological analysis was performed by examining each patient's journey timepoint with reference to symptom onset. RESULTS: The mortality rate for 369 patients included was 18.9%. Patients treated conservatively, endoscopically, surgically, or combined approaches had mortality rates of 24.1%, 23.7%, 8.7%, and 18.2%, respectively. The predictive variables for mortality were Charlson comorbidity index, haemoglobin count, leucocyte count, creatinine levels, cause of perforation, presence of cancer, hospital transfer, CT findings, whether a contrast swallow was performed, and intervention type. Stepwise interval model showed that time to diagnosis was the most significant contributor to mortality. CONCLUSIONS: Non-surgical strategies have better outcomes and may be preferred in selected cohorts to manage perforations. Outcomes can be significantly improved through better risk-stratification based on afore-mentioned modifiable risk factors.

OBJECTIVE: To determine the impact of delayed surgical intervention following chemoradiotherapy (CRT) on survival from esophageal cancer. BACKGROUND: CRT is a core component of multimodality treatment for locally advanced esophageal cancer. The timing of surgery following CRT may influence the probability of performing an oncological resection and the associated operative morbidity. METHODS: This was an international, multicenter, cohort study, including patients from 17 centers who received CRT followed by surgery between 2010 and 2020. In the main analysis, patients were divided into 4 groups based upon the interval between CRT and surgery (0-50, 51-100, 101-200, and >200 days) to assess the impact upon 90-day mortality and 5-year overall survival. Multivariable logistic and Cox regression provided hazard ratios (HRs) with 95% CIs adjusted for relevant patient, oncological, and pathologic confounding factors. RESULTS: A total of 2867 patients who underwent esophagectomy after CRT were included. After adjustment for relevant confounders, prolonged interval following CRT was associated with an increased 90-day mortality compared with 0 to 50 days (reference): 51 to 100 days (HR=1.54, 95% CI: 1.04-2.29), 101 to 200 days (HR=2.14, 95% CI: 1.37-3.35), and >200 days (HR=3.06, 95% CI: 1.64-5.69). Similarly, a poorer 5-year overall survival was also observed with prolonged interval following CRT compared with 0 to 50 days (reference): 101 to 200 days (HR=1.41, 95% CI: 1.17-1.70), and >200 days (HR=1.64, 95% CI: 1.24-2.17). CONCLUSIONS: Prolonged interval following CRT before esophagectomy is associated with increased 90-day mortality and poorer long-term survival. Further investigation is needed to understand the mechanism that underpins these adverse outcomes observed with a prolonged interval to surgery.

BACKGROUND: The National Oesophago-Gastric Cancer Audit (NOGCA) captures patient data from diagnosis to end of primary treatment for all patients with oesophagogastric (OG) cancer in England and Wales. This study assessed changes in patient characteristics, treatments received, and outcomes for OG cancer surgery for the period 2012-2020, and examined which factors may have led to changes in clinical outcomes over this time. METHODS: Patients diagnosed with OG cancer between April 2012 and March 2020 were included. Descriptive statistics were used to summarize patient demographics, disease site, type, and stage, patterns of care, and outcomes over time. The treatment variables of unit case volume, surgical approach, and neoadjuvant therapy were included. Regression models were used to examine associations between surgical outcomes (duration of stay and mortality), and patient and treatment variables. RESULTS: In total, 83 393 patients diagnosed with OG cancer during the study period were included. Patient demographics and cancer stage at diagnosis showed little change over time. Altogether, 17 650 patients underwent surgery as part of radical treatment. These patients had increasingly more advanced cancers, and a greater likelihood of pre-existing comorbidity in more recent years. Significant decreases in mortality rates and duration of stay were noted, along with improvements in oncological outcomes (nodal yields and margin positivity rates). Following adjustment for patient and treatment variables, increasing audit year and trust volume were associated, respectively, with improved postoperative outcomes: lower 30-day mortality (odds ratio (OR) 0.93 (95 per cent c.i. 0.88 to 0.98) and OR 0.99 (95 per cent c.i. 0.99-0.99)) and lower 90-day mortality (OR 0.94 (95 per cent c.i. 0.91 to 0.98) and OR 0.99 (95 per cent c.i. 0.99-0.99)), and a reduction in duration of postoperative stay (incidence rate ratio (IRR) 0.98 (95 per cent c.i. 0.97 to 0.98) and IRR 0.99 (95 per cent c.i. 0.99 to 0.99)). CONCLUSION: Outcomes of OG cancer surgery have improved over time, despite little evidence of improvements in early diagnosis. The underlying drivers for improvements in outcome are multifactorial.

OBJECTIVES: 2-deoxy-2[18F]Fluoro-D-glucose (FDG) PET-CT has an emerging role in assessing response to neoadjuvant therapy in oesophageal cancer. This study evaluated FDG PET-CT in predicting pathological tumour response (pTR), pathological nodal response (pNR) and survival. METHODS: Cohort study of 75 patients with oesophageal or oesophago-gastric junction (GOJ) adenocarcinoma treated with neoadjuvant chemotherapy then surgery at Guy's and St Thomas' NHS Foundation Trust, London (2017-2020). Standardised uptake value (SUV) metrics on pre- and post-treatment FDG PET-CT in the primary tumour (mTR) and loco-regional lymph nodes (mNR) were derived. Optimum SUVmax thresholds for predicting pathological response were identified using receiver operating characteristic analysis. Predictive accuracy was compared to PERCIST (30% SUVmax reduction) and MUNICON (35%) criteria. Survival was assessed using Cox regression. RESULTS: Optimum tumour SUVmax decrease for predicting pTR was 51.2%. A 50% cut-off predicted pTR with 73.5% sensitivity, 69.2% specificity and greater accuracy than PERCIST or MUNICON (area under the curve [AUC] 0.714, PERCIST 0.631, MUNICON 0.659). Using a 30% SUVmax threshold, mNR predicted pNR with high sensitivity but low specificity (AUC 0.749, sensitivity 92.6%, specificity 57.1%, p = 0.010). pTR, mTR, pNR and mNR were independent predictive factors for survival (pTR hazard ratio [HR] 0.10 95% confidence interval [CI] 0.03-0.34; mTR HR 0.17 95% CI 0.06-0.48; pNR HR 0.17 95% CI 0.06-0.54; mNR HR 0.13 95% CI 0.02-0.66). CONCLUSIONS: Metabolic tumour and nodal response predicted pTR and pNR, respectively, in patients with oesophageal or GOJ adenocarcinoma. However, currently utilised response criteria may not be optimal. pTR, mTR, pNR and mNR were independent predictors of survival. KEY POINTS: ⢠FDG PET-CT has an emerging role in evaluating response to neoadjuvant therapy in patients with oesophageal cancer. ⢠Prospective cohort study demonstrated that metabolic response in the primary tumour and lymph nodes was predictive of pathological response in a cohort of patients with adenocarcinoma of the oesophagus or oesophago-gastric junction treated with neoadjuvant chemotherapy followed by surgical resection. ⢠Patients who demonstrated a response to neoadjuvant chemotherapy in the primary tumour or lymph nodes on FDG PET-CT demonstrated better survival and reduced rates of tumour recurrence.

BACKGROUND: This systematic review aimed to analyse the use of the SX-ELLA biodegradable stent (BDS) for benign oesophageal strictures through the assessment of clinical and technical success, differences in pre- and post-BDS insertion dysphagia scores, rates of stent migration, and safety. METHODS: A systematic review was reported according to PRISMA guidelines, with a prospectively registered protocol. The databases PubMed, Embase, SCOPUS, and ClinicalTrials.gov were searched up to March 2022. Studies assessing the use of the SX-ELLA BDS in adults with benign oesophageal strictures were included. A pooled data analysis was conducted to analyse the clinical and technical success associated with BDS use, rate of stent migration, and safety. RESULTS: Of the 1509 articles identified, 16 studies treating 246 patients were eligible for inclusion. BDS was clinically successful in 41.9% of cases (95% CI = 35.7 - 48.1%), defined as those who experienced complete symptom resolution following BDS insertion. Technical success was achieved in 97.2% of patients (95% CI = 95.1 - 99.3%). A pooled analysis concluded a decrease in mean dysphagia score of 1.8 points (95% CI = 1.68 - 1.91) following BDS insertion. Re-intervention was required in 89 patients (36.2%, 95% CI = 30.2 - 42.2%), whilst stent migration occurred in 6.5% of patients (95% CI = 3.4 - 9.6%). A total of 37 major clinical complications related to BDS insertion were reported (15.0%, 95% CI = 10.5 - 19.5%). CONCLUSION: The pooled data analysis demonstrates the high technical and moderate clinical success of the SX-ELLA biodegradable stent, supporting its use for benign oesophageal strictures in adults. However, greater evidence is required for more robust conclusions to be made in terms of success when compared to alternative methods of intervention, such as endoscopic dilation.

BACKGROUND: New evidence has emerged since latest guidelines on the management of paraesophageal hernia, and guideline development methodology has evolved. Members of the European Association for Endoscopic Surgery have prioritized the management of paraesophageal hernia to be addressed by pertinent recommendations. OBJECTIVE: To develop evidence-informed clinical practice recommendations on paraesophageal hernias, through evidence synthesis and a structured evidence-to-decision framework by an interdisciplinary panel of stakeholders. METHODS: We performed three systematic reviews, and we summarized and appraised the certainty of the evidence using the GRADE methodology. A panel of general and upper gastrointestinal surgeons, gastroenterologists and a patient advocate discussed the evidence in the context of benefits and harms, the certainty of the evidence, acceptability, feasibility, equity, cost and use of resources, moderated by a Guidelines International Network-certified master guideline developer and chair. We developed the recommendations in a consensus meeting, followed by a modified Delphi survey. RESULTS: The panel suggests surgery over conservative management for asymptomatic/minimally symptomatic paraesophageal hernias (conditional recommendation), and recommends conservative management over surgery for asymptomatic/minimally symptomatic paraesophageal hernias in frail patients (strong recommendation). Further, the panel suggests mesh over sutures for hiatal closure in paraesophageal hernia repair, fundoplication over gastropexy in elective paraesophageal hernia repair, and gastropexy over fundoplication in patients who have cardiopulmonary instability and require emergency paraesophageal hernia repair (conditional recommendation). A strong recommendation means that the proposed course of action is appropriate for the vast majority of patients. A conditional recommendation means that most patients would opt for the proposed course of action, and joint decision-making of the surgeon and the patient is required. Accompanying evidence summaries and evidence-to-decision frameworks should be read when using the recommendations. This guideline applies to adult patients with moderate to large paraesophageal hernias type II to IV with at least 50% of the stomach herniated to the thoracic cavity. The full guideline with user-friendly decision aids is available in https://app.magicapp.org/#/guideline/j7q7Gn . CONCLUSION: An interdisciplinary panel provides recommendations on key topics on the management of paraesophageal hernias using highest methodological standards and following a transparent process.

Hereditary hemorrhagic telangiectasia (HHT) is a rare angiogenic disorder causing chronic gastrointestinal bleeding, epistaxis, and severe anemia. Pazopanib is an oral multi-kinase angiogenesis inhibitor with promise to treat bleeding in HHT. We analyzed outcomes of HHT patients with the most severe bleeding causing RBC transfusion dependence treated on a predefined institutional pazopanib treatment pathway (with data collected retrospectively). The primary endpoint was achievement of transfusion independence. Secondary endpoints included hemoglobin, epistaxis severity score, RBC transfusion and iron infusion requirements, number of local hemostatic procedures, ferritin and transferrin saturation, compared using paired and repeated measures mean tests. Thirteen transfusion-dependent HHT patients received pazopanib [median (range) dose 150 (25-300) mg daily)] for a median of 22 months. All patients achieved transfusion independence. Compared with pretreatment, pazopanib increased mean hemoglobin by 4.8 (95% CI, 3.6-5.9) g/dL (7.8 vs. 12.7 g/dL, P < 0.0001) and decreased mean epistaxis severity score by 4.77 (3.11-6.44) points (7.20 vs. 2.43 points, P < 0.0001) after 12 months of treatment. Compared with 3 months of pretreatment, RBC transfusions decreased by 93% (median of 16.0 vs. 0.0 units, P < 0.0001) and elemental iron infusion decreased by 92% (median of 4500 vs. 0 mg, P = 0.005) during the first 3 months of treatment; improvements were maintained over time. Pazopanib was well-tolerated: hypertension, lymphocytopenia, and fatigue were the most common TEAEs. In conclusion, pazopanib was safe and effective to manage severe bleeding in HHT, liberating all patients from transfusion dependence and normalizing hematologic parameters at doses lower than used to treat malignancies. These findings require confirmation in a randomized trial.

BACKGROUND: Pulmonary complications are the most common morbidity after oesophagectomy, contributing to mortality and prolonged postoperative recovery, and have a negative impact on health-related quality of life. A variety of single or bundled interventions in the perioperative setting have been developed to reduce the incidence of pulmonary complications. Significant variation in practice exists across the UK. The aim of this modified Delphi consensus was to deliver clear evidence-based consensus recommendations regarding intraoperative and postoperative care that may reduce pulmonary complications after oesophagectomy. METHODS: With input from a multidisciplinary group of 23 experts in the perioperative management of patients undergoing surgery for oesophageal cancer, a modified Delphi method was employed. Following an initial systematic review of relevant literature, a range of anaesthetic, surgical, and postoperative care interventions were identified. These were then discussed during a two-part virtual conference. Recommendation statements were drafted, refined, and agreed by all attendees. The level of evidence supporting each statement was considered. RESULTS: Consensus was reached on 12 statements on topics including operative approach, pyloric drainage strategies, intraoperative fluid and ventilation strategies, perioperative analgesia, postoperative feeding plans, and physiotherapy interventions. Seven additional questions concerning the perioperative management of patients undergoing oesophagectomy were highlighted to guide future research. CONCLUSION: Clear consensus recommendations regarding intraoperative and postoperative interventions that may reduce pulmonary complications after oesophagectomy are presented.

PURPOSE: Long-lasting symptoms and reductions in quality of life are common after oesophago-gastric surgery. Post-operative follow-up has traditionally focussed on tumour recurrence and survival, but there is a growing need to also identify and treat functional sequelae to improve patients' recovery. METHODS: An electronic survey was circulated via a British national charity for patients undergoing oesophago-gastric surgery and their families. Patients were asked about post-operative symptoms they deemed important to their quality of life, as well as satisfaction and preferences for post-operative follow-up. Differences between satisfied and dissatisfied patients with reference to follow-up were assessed. RESULTS: Among 362 respondents with a median follow-up of 58 months since surgery (range 3-412), 36 different symptoms were reported as being important to recovery and quality of life after surgery, with a median of 13 symptoms per patient. Most (84%) respondents indicated satisfaction with follow-up. Satisfied patients were more likely to have received longer follow-up (5-year or longer follow-up 60% among satisfied patients vs 27% among unsatisfied, p < 0.001). These were also less likely to have seen a dietitian as part of routine follow-up (37% vs 58%, p = 0.005). CONCLUSION: This patient survey highlights preferences regarding follow-up after oesophago-gastrectomy. Longer follow-up and dietician involvement improved patient satisfaction. Patients reported being concerned by a large number of gastrointestinal and non-gastrointestinal symptoms, highlighting the need for multidisciplinary input and a consensus on how to manage the poly-symptomatic patient.

BACKGROUND: Corrosive ingestion injuries are rare but clinically significant events, potentially associated with high morbidity and mortality. The low volume of cases limits guideline development. We report a 10-year experience of our tertiary centre focusing on cases requiring specialist care. METHODS: All adults treated following corrosive ingestion between 2010 and 2020 were included. Blood results, imaging and endoscopic findings were reviewed. Patients were stratified based on endoscopic findings. Emergency and delayed management was analysed along with short and long-term outcomes. Predictive value of early outcome indicators was investigated. RESULTS: Eighty-one patients were included, with an average follow-up of 5 years. Patients with injuries ≤ Zargar 2A (n = 15) had long-term outcomes similar to the ones with negative endoscopic findings (n = 51). All fifteen patients suffering injuries Zargar ≥ 2B required ITU and four died (26.6%). All deaths occurred within 50 days of ingestion, had Zargar grade ≥ 3 and airway involvement. Five patients (33%) required emergency operations, two of which died. All Zargar ≥ 2B injury survivors (n = 11) developed strictures and/or tracheo-esophageal fistulae (18%), required multiple admissions and prolonged nutritional support; five required delayed resections. Zargar grade ≥ 2B, airway damage, and increased CRP on admission correlated with unfavourable outcomes. CONCLUSION: Corrosive ingestion injuries up to Zargar 2A do not cause long-term sequelae and can be managed locally. Injuries > 2B bear high mortality and will cause sequelae. Early identification of severe injuries and transfer to specialist centres with multidisciplinary ITU, OG, thoracic and ENT expertise is recommended.

BACKGROUND: Modern enhanced recovery protocols discourage drain use due to negative impacts on patient comfort, mobility, and recovery, and lack of proven clinical benefit. After oesophagectomy, however, drains are still routinely placed. This review aimed to assess the evidence for, and how best to use chest drains after oesophageal surgery. METHODS: A systematic literature search was performed in Medline, Embase and Cochrane collaboration databases. Studies reporting outcomes for different types or uses of thoracic drainage, or outcomes related to drains after trans-thoracic oesophagectomy were included. Studies were collated into domains based on variations in number, position, type, removal criteria, diagnostic use and complications of drains. Methodological quality was assessed with Newcastle-Ottawa and Jadad scores. RESULTS: Among 434 potentially relevant studies, 27 studies met the inclusion criteria and these included 2564 patients. Studies that examined the number of drains showed pain reduction with a single drain compared to multiple drains (3 studies, n = 103), and transhiatal placement compared to intercostal (6 studies, n = 425). Amylase levels may aid diagnosis of anastomotic leak (9 studies, n = 888). Narrow calibre Blake drains may effectively drain both air and fluid (2 studies, n = 163). Drain removal criteria by daily drainage volumes of up to 300 mL did not impact subsequent effusion rates (2 studies, n = 130). Complications related directly to drains were reported by 3 studies (n = 59). CONCLUSION: Available evidence on the impact of thoracic drainage after oesophagectomy is limited, but has the potential to negatively affect outcomes. Further research is required to determine optimum drainage strategies.

BACKGROUND: To assess the outcomes of patients with early esophageal cancer and high-grade dysplasia comparing esophagectomy, the historical treatment of choice, to endoscopic eradication therapy (EET). METHODS: Retrospective cohort study of consecutive patients with early esophageal cancer/high-grade dysplasia, treated between 2000 and 2018 at a tertiary center. Primary outcomes were all-cause and disease-specific mortality assessed by multivariable Cox regression and a propensity score matching sub analysis, providing hazard ratios (HR) with 95% confidence intervals (CI) adjusted for age, tumor grade (G1/2 vs. G3), tumor stage, and lymphovascular invasion. Secondary outcomes included complications, hospital stay, and overall costs. RESULTS: Among 269 patients, 133 underwent esophagectomy and 136 received EET. Adjusted survival analysis showed no difference between groups regarding all-cause mortality (HR 1.85, 95% CI 0.73, 4.72) and disease-specific mortality (HR 1.10, 95% CI 0.26, 4.65). In-hospital and 30-day mortality was 0% in both groups. The surgical group had a significantly higher rate of complications (Clavien-Dindo ≥3 26.3% vs. endoscopic therapy 0.74%), longer in-patient stay (median 14 vs. 0 days endoscopic therapy) and higher hospital costs(£16 360 vs. £8786 per patient). CONCLUSION: This series of patients treated during a transition period from surgery to EET, demonstrates a primary endoscopic approach does not compromise oncological outcomes with the benefit of fewer complications, shorter hospital stays, and lower costs compared to surgery. It should be available as the gold standard treatment for patients with early esophageal cancer. Those with adverse prognostic features may still benefit from esophagectomy.

BACKGROUND: There is increasing evidence for the use of exercise in cancer patients and data supporting enhanced tumour volume reduction following chemotherapy in animal models. To date, there is no reported histopathological evidence of a similar oncological benefit in oesophageal cancer. METHODS: A prospective non-randomised trial compared a structured prehabilitation exercise intervention during neoadjuvant chemotherapy and surgery versus conventional best-practice for oesophageal cancer patients. Biochemical and body composition analyses were performed at multiple time points. Outcome measures included radiological and pathological markers of disease regression. Logistic regression calculated ORs with 95% CI for the likelihood of pathological response adjusting for chemotherapy regimen and chemotherapy delivery. RESULTS: Comparison of the Intervention (n=21) and Control (n=19) groups indicated the Intervention group had higher rates of tumour regression (Mandard TRG 1-3 Intervention n=15/20 (75%) vs Control n=7/19 (36.8%) p=0.025) including adjusted analyses (OR 6.57; 95% CI 1.52 to 28.30). Combined tumour and node downstaging (Intervention n=9 (42.9%) vs Control n=3 (15.8%) p=0.089) and Fat Free Mass index were also improved (Intervention 17.8 vs 18.7 kg/m2; Control 16.3 vs 14.7 kg/m2, p=0.026). Differences in markers of immunity (CD-3 and CD-8) and inflammation (IL-6, VEGF, INF-y, TNFa, MCP-1 and EGF) were observed. CONCLUSION: The results suggest improved tumour regression and downstaging in the exercise intervention group and should prompt larger studies on this topic. TRIAL REGISTRATION NUMBER: NCT03626610.

BACKGROUND: A high Mandard score implies a non-response to chemotherapy in oesophageal adenocarcinoma. However, some patients exhibit tumour volume reduction and a nodal response despite a high score. This study examines survival and recurrence patterns in these patients. METHODS: Clinicopathological factors were analysed using multivariable Cox regression assessing time to death and recurrence. Computed tomography-estimated tumour volume change was examined in a subgroup of consecutive patients. RESULTS: Five hundred and fifty-five patients were included. Median survival was 55 months (Mandard 1-3) and 21 months (Mandard 4 and 5). In the Mandard 4 and 5 group (332 patients), comparison between complete nodal responders and persistent nodal disease showed improved survival (90 vs 18 months), recurrence rates (locoregional 14.75 vs 28.74%, systemic 24.59 vs 48.42%) and circumferential resection margin positivity (22.95 vs 68.11%). Complete nodal response independently predicted improved survival (hazard ratio 0.34 (0.16-0.74). Post-chemotherapy tumour volume reduction was greater in patients with a complete nodal response (-16.3 vs -7.7 cm3, p = 0.033) with no significant difference between Mandard groups. CONCLUSION: Patients with a complete nodal response to chemotherapy have significantly improved outcomes despite a poor Mandard score. High Mandard score does not correspond with a non-response to chemotherapy in all cases and patients with nodal downstaging may still benefit from adjuvant chemotherapy.

Hereditary hemorrhagic telangiectasia (HHT, Osler-Weber-Rendu disease) is a rare multisystem vascular disorder causing chronic gastrointestinal bleeding, epistaxis, and severe anemia. Bevacizumab, an anti-vascular endothelial growth factor antibody, may be effective to treat bleeding in HHT. This international, multicenter, retrospective study evaluated the use of systemic bevacizumab to treat HHT-associated bleeding and anemia at 12 HHT treatment centers. Hemoglobin, epistaxis severity score, red cell units transfused, and intravenous iron infusions before and after treatment were evaluated using paired means testing and mixed-effects linear models. 238 HHT patients received bevacizumab for a median of 12 (range, 1-96) months. Compared with pretreatment, bevacizumab increased mean hemoglobin by 3.2 g/dL (95% CI, 2.9-3.5 g/dL) [mean hemoglobin 8.6 (8.5, 8.8) g/dL versus 11.8 (11.5, 12.1) g/dL, p<0.0001)] and decreased the epistaxis severity score (ESS) by 3.4 (3.2-3.7) points [mean ESS 6.8 (6.6-7.1) versus 3.4 (3.2-3.7), P<0.0001] during the first year of treatment. Compared with 6 months pretreatment, RBC units transfused decreased by 82% [median of 6.0 (IQR 0.0-13.0) units versus 0 (IQR, 0.0-1.0) units, P<0.0001] and iron infusions decreased by 70% [median of 6.0 (1.0-18.0) infusions versus 1.0 (0.0-4.0) infusions, P<0.0001] during the first 6 months of bevacizumab treatment. Outcomes were similar regardless of underlying pathogenic mutation. Following initial induction infusions, continuous/scheduled bevacizumab maintenance achieved higher hemoglobin and lower ESS than intermittent/as needed maintenance but with more drug exposure. Bevacizumab was well tolerated: hypertension, fatigue, and proteinuria were the most common adverse events. Venous thromboembolism occurred in 2% of patients. In conclusion, systemic bevacizumab was safe and effective to manage chronic bleeding and anemia in HHT.

BACKGROUND: Most patients presenting with oesophageal cancer do so with advanced disease not suitable for surgery. However, there are examples of encouraging survival following surgery in highly selected patients who respond well to chemotherapy. METHODS: This was a retrospective cohort study of patients who presented with advanced but nonvisceral metastatic oesophageal cancer. Consecutive patients on a prolonged primary chemotherapy pathway who underwent surgical resection following a favourable response to chemotherapy were included. Survival and recurrence rates were analysed using Cox regression, providing hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: A total of 57 patients included in the cohort operated between 2007 and 2015, the overall median survival was 44 months and the 5-year survival was 42%. Prechemotherapy cN0/cN1 (HR: 0.27, 95% CI: 0.12-0.62) conferred an independent survival advantage compared to cN2 and cN3 disease. Poor differentiation (HR: 2.46, 95% CI: 1.11-5.42), R1 resection (HR: 2.43, 95% CI: 1.14-5.19) and advanced nodal status (HR: 3.28, 95% CI: 1.44-7.47) predicted worse survival on univariable analysis. Poor differentiation (HR: 3.93, 95% CI: 1.62-9.56) was independently associated with poor survival when adjusted for other variables. CONCLUSION: Patients who present with advanced inoperable oesophageal cancer who have a favourable response to chemotherapy represent a limited group of patients who may benefit from surgery.
