Background: Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), poses a significant risk of morbidity and mortality in surgical patients, especially those undergoing head and neck cancer surgery with microvascular free flap reconstruction. These patients are at a heightened risk of VTE due to numerous patient and surgical risk factors. VTE chemoprophylaxis guidelines in these patients are limited due to a distinct paucity of research. This study aims to contribute to this scarcity of information, providing guidance for surgeons., Methods: This retrospective cohort study evaluated the efficacy and safety of subcutaneous unfractionated heparin administered every 8 h versus every 12 h for postoperative VTE prophylaxis in patients undergoing head and neck resections with immediate free flap reconstruction. Data was collected from hospital medical records between January 2010 to December 2021. Patient demographics, operative details, and outcomes, including incidence of VTE and bleeding complications, were analyzed., Results: Among 622 patients, those receiving heparin every 8 h (n = 393) demonstrated a significantly lower rate of VTE (0.8%) compared to 12-hourly group (n = 229; 3.9%) (p = 0.006). Additionally, there were no significant differences in the rates of postoperative hematoma between the two groups (9.4% versus 7.9% respectively, p = 0.510)., Conclusion: Our study suggests that an increased daily dose of unfractionated heparin every 8 h for VTE chemoprophylaxis is superior to a 12-hourly regimen with comparable bleeding profiles. Further multicentre, prospective studies are needed to validate these results and compare the efficacy and safety of unfractionated heparin with other agents such as low-molecular-weight heparin in this patient group., (© 2024 Wiley Periodicals LLC.)

Objective: To compare quality of recovery in patients receiving epidural or paravertebral analgesia for minimally invasive esophagectomy (MIE)., Summary Background Data: Paravertebral analgesia may be a promising alternative to epidural analgesia, avoiding potential side effects and improving postoperative recovery., Methods: This randomized controlled superiority trial was conducted across four Dutch centers with esophageal cancer patients scheduled for transthoracic MIE with intrathoracic anastomosis, randomizing patients to receive either epidural or paravertebral analgesia. The primary outcome was Quality of Recovery (QoR-40) on the third postoperative day (POD). Secondary outcomes included quality of life, postoperative pain, opioid consumption, inotropic/vasopressor medication use, hospital stay, complications, readmission, and mortality., Results: From December 2019 to February 2023, 192 patients were included: 94 received epidural and 98 paravertebral analgesia. QoR-40 score on POD3 was not different between groups (mean difference 3.7, 95%CI -2.3 to 9.7; P=0.268). Epidural patients had significant higher QoR-40 scores on POD1 and 2 (mean difference 7.7, 95%CI 2.3-13.1; P=0.018 and mean difference 7.3, 95%CI 1.9-12.7; P=0.020) and lower pain scores (median 1 versus 2; P=<0.001 and median 1 versus 2; P=0.033). More epidural patients required vasopressor medication on POD1 (38.3% versus 13.3%; P<0.001). Urinary catheters were removed earlier in the paravertebral group (median POD3 versus 4; P=<0.001). No significant differences were found in postoperative complications or hospital/Intensive Care Unit stay., Conclusions: This randomized controlled trial did not demonstrate superiority of paravertebral over epidural analgesia regarding quality of recovery on POD3 after MIE. Both techniques are effective and can be offered in clinical practice., Competing Interests: Declaration of interests Prof. dr.

Introduction: The OligoMetastatic Esophagogastric Cancer (OMEC) project aims to provide clinical practice guidelines for the definition, diagnosis, and treatment of esophagogastric oligometastatic disease (OMD)., Methods: Guidelines were developed according to AGREE II and GRADE principles. Guidelines were based on a systematic review (OMEC-1), clinical case discussions (OMEC-2), and a Delphi consensus study (OMEC-3) by 49 European expert centers for esophagogastric cancer. OMEC identified patients for whom the term OMD is considered or could be considered. Disease-free interval (DFI) was defined as the time between primary tumor treatment and detection of OMD., Results: Moderate to high quality of evidence was found (i.e. 1 randomized and 4 non-randomized phase II trials) resulting in moderate recommendations. OMD is considered in esophagogastric cancer patients with 1 organ with ≤ 3 metastases or 1 involved extra-regional lymph node station. In addition, OMD continues to be considered in patients with OMD without progression in number of metastases after systemic therapy. 18 F-FDG PET/CT imaging is recommended for baseline staging and for restaging after systemic therapy when local treatment is considered. For patients with synchronous OMD or metachronous OMD and a DFI ≤ 2 years, recommended treatment consists of systemic therapy followed by restaging to assess suitability for local treatment. For patients with metachronous OMD and DFI > 2 years, upfront local treatment is additionally recommended., Discussion: These multidisciplinary European clinical practice guidelines for the uniform definition, diagnosis and treatment of esophagogastric OMD can be used to standardize inclusion criteria in future clinical trials and to reduce variation in treatment., Competing Interests: Declaration of Competing Interest Dr. van Laarhoven reports a consultant or advisory role: Amphera, Anocca, Astellas, AstraZeneca, Beigene, Boehringer, Daiichy-Sankyo, Dragonfly, MSD, Myeloid, Servier; Research funding, medication supply, and/or other research support: Auristone, Incyte, Merck, ORCA, Servier; Speaker role: Astellas, Beigene, Benecke, BMS, Daiichy-Sankyo, JAAP, Medtalks, Novartis, Springer, Travel Congress Management B.V.

Importance: Minimally invasive esophagectomy (MIE) is a complex procedure with substantial learning curves. In other complex minimally invasive procedures, suboptimal surgical performance has convincingly been associated with less favorable patient outcomes as assessed by peer review of the surgical procedure., Objective: To develop and validate a procedure-specific competency assessment tool (CAT) for MIE., Design, Setting, and Participants: In this international quality improvement study, a procedure-specific MIE-CAT was developed and validated. The MIE-CAT contains 8 procedural phases, and 4 quality components per phase are scored with a Likert scale ranging from 1 to 4. For evaluation of the MIE-CAT, intraoperative MIE videos performed by a single surgical team in the Esophageal Center East Netherlands were peer reviewed by 18 independent international MIE experts (with more than 120 MIEs performed). Each video was assessed by 2 or 3 blinded experts to evaluate feasibility, content validity, reliability, and construct validity. MIE-CAT version 2 was composed with refined content aimed at improving interrater reliability. A total of 32 full-length MIE videos from patients who underwent MIE between 2011 and 2020 were analyzed. Data were analyzed from January 2021 to January 2023., Exposure: Performance assessment of transthoracic MIE with an intrathoracic anastomosis., Main Outcomes and Measures: Feasibility, content validity, interrater and intrarater reliability, and construct validity, including correlations with both experience of the surgical team and clinical parameters, of the developed MIE-CAT., Results: Experts found the MIE-CAT easy to understand and easy to use to grade surgical performance. The MIE-CAT demonstrated good intrarater reliability (range of intraclass correlation coefficients [ICCs], 0.807 [95% CI, 0.656 to 0.892] for quality component score to 0.898 [95% CI, 0.846 to 0.932] for phase score). Interrater reliability was moderate (range of ICCs, 0.536 [95% CI, -0.220 to 0.994] for total MIE-CAT score to 0.705 [95% CI, 0.473 to 0.846] for quality component score), and most discrepancies originated in the lymphadenectomy phases. Hypothesis testing for construct validity showed more than 75% of hypotheses correct: MIE-CAT performance scores correlated with experience of the surgical team (r = 0.288 to 0.622), blood loss (r = -0.034 to -0.545), operative time (r = -0.309 to -0.611), intraoperative complications (r = -0.052 to -0.319), and severe postoperative complications (r = -0.207 to -0.395). MIE-CAT version 2 increased usability. Interrater reliability improved but remained moderate (range of ICCs, 0.666 to 0.743), and most discrepancies between raters remained in the lymphadenectomy phases., Conclusions and Relevance: The MIE-CAT was developed and its feasibility, content validity, reliability, and construct validity were demonstrated. By providing insight into surgical performance of MIE, the MIE-CAT might be used for clinical, training, and research purposes.

Background: Local treatment improves the outcomes for oligometastatic disease (OMD, i.e. an intermediate state between locoregional and widespread disseminated disease). However, consensus about the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer is lacking. The aim of this study was to develop a multidisciplinary European consensus statement on the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer., Methods: In total, 65 specialists in the multidisciplinary treatment for oesophagogastric cancer from 49 expert centres across 16 European countries were requested to participate in this Delphi study. The consensus finding process consisted of a starting meeting, 2 online Delphi questionnaire rounds and an online consensus meeting. Input for Delphi questionnaires consisted of (1) a systematic review on definitions of oligometastatic oesophagogastric cancer and (2) a discussion of real-life clinical cases by multidisciplinary teams. Experts were asked to score each statement on a 5-point Likert scale. The agreement was scored to be either absent/poor (<50%), fair (50%-75%) or consensus (≥75%)., Results: A total of 48 experts participated in the starting meeting, both Delphi rounds, and the consensus meeting (overall response rate: 71%). OMD was considered in patients with metastatic oesophagogastric cancer limited to 1 organ with ≤3 metastases or 1 extra-regional lymph node station (consensus). In addition, OMD was considered in patients without progression at restaging after systemic therapy (consensus). For patients with synchronous or metachronous OMD with a disease-free interval ≤2 years, systemic therapy followed by restaging to consider local treatment was considered as treatment (consensus). For metachronous OMD with a disease-free interval >2 years, either upfront local treatment or systemic treatment followed by restaging was considered as treatment (fair agreement)., Conclusion: The OMEC project has resulted in a multidisciplinary European consensus statement for the definition, diagnosis and treatment of oligometastatic oesophagogastric adenocarcinoma and squamous cell cancer. This can be used to standardise inclusion criteria for future clinical trials., Competing Interests: Conflict of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. van Laarhoven reports grants or advisory/speaker role from: Astellas, BMS, Dragonfly, Lilly, Merck, Novartis, Nordic Pharma, Servier; research funding or medical supply from: Bayer, BMS, Celgene, Janssen, Incyte, Lilly, Merck, Nordic Pharma, Philips, Roche, Servier; and has received unrestricted research funding (non-commercial) from: Dutch Cancer Society, NWO/ZonMw, European Research Council, MaagLeverDarm Stichting.

Background: There is currently a lack of evidence-based guidelines regarding surveillance for recurrence after esophageal and gastric (OG) cancer surgical resection, and which symptoms should prompt endoscopic or radiological investigations for recurrence. The aim of this study was to develop a core symptom set using a modified Delphi consensus process that should guide clinicians to carry out investigations to look for suspected recurrent OG cancer in previously asymptomatic patients., Methods: A web-based survey of 42 questions was sent to surgeons performing OG cancer resections at high volume centers. The first section evaluated the structure of follow-up and the second, determinants of follow-up. Two rounds of a modified Delphi consensus process and a further consensus workshop were used to determine symptoms warranting further investigations. Symptoms with a 75% consensus agreement as suggestive of recurrent cancer were included in the core symptom set., Results: 27 surgeons completed the questionnaires. A total of 70.3% of centers reported standardized surveillance protocols, whereas 3.7% of surgeons did not undertake any surveillance in asymptomatic patients after OG cancer resection. In asymptomatic patients, 40.1% and 25.9% of centers performed routine imaging and endoscopy, respectively. The core set that reached consensus, consisted of eight symptoms that warranted further investigations included; dysphagia to solid food, dysphagia to liquids, vomiting, abdominal pain, chest pain, regurgitation of foods, unexpected weight loss and progressive hoarseness of voice., Conclusion: There is global variation in monitoring patients after OG cancer resection. Eight symptoms were identified by the consensus process as important in prompting radiological or endoscopic investigation for suspected recurrent malignancy. Further randomized controlled trials are necessary to link surveillance strategies to survival outcomes and evaluate prognostic value., (© The Author(s) 2022.

Objective: To describe the pooled learning curves of Ivor Lewis totally minimally invasive esophagectomy (TMIE) in hospitals stratified by predefined hospital- and surgeon-related factors., Background: Ivor Lewis (TMIE is known to have a long learning curve which is associated with considerable learning associated morbidity. It is unknown whether hospital and surgeon characteristics are associated with more efficient learning., Methods: A retrospective analysis of prospectively collected data of consecutive Ivor Lewis TMIE patients in 14 European hospitals was performed. Outcome parameters used as proxy for efficient learning were learning curve length, learning associated morbidity, and the plateau level regarding anastomotic leakage and textbook outcome. Pooled incidences were plotted for the factor-based subgroups using generalized additive models and 2-phase models. Casemix predicted outcomes were plotted and compared with observed outcomes. The investigated factors included annual volume, TMIE experience, clinic visits, courses and fellowships followed, and proctor supervision., Results: This study included 2121 patients. The length of the learning curve was shorter for centers with an annual volume >50 compared to centers with an annual volume <50. Analysis with an annual volume cut-off of 30 cases showed similar but less pronounced results. No outcomes suggesting more efficient learning were found for longer experience as consultant, visiting an expert clinic, completing a minimally invasive esophagectomy fellowship or implementation under proctor supervision., Conclusions: More efficient learning was observed in centers with higher annual volume. Visiting an expert clinic, completing a fellowship, or implementation under a proctor's supervision were not associated with more efficient learning., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 The Author(s).

Background: Consensus about the definition and treatment of oligometastatic oesophagogastric cancer is lacking., Objective: To assess the definition and treatment of oligometastatic oesophagogastric cancer across multidisciplinary tumour boards (MDTs) in Europe., Material and Methods: European expert centers (n = 49) were requested to discuss 15 real-life cases in their MDT with at least a medical, surgical, and radiation oncologist present. The cases varied in terms of location and number of metastases, histology, timing of detection (i.e. synchronous versus metachronous), primary tumour treatment status, and response to systemic therapy. The primary outcome was the agreement in the definition of oligometastatic disease at diagnosis and after systemic therapy. The secondary outcome was the agreement in treatment strategies. Treatment strategies for oligometastatic disease were categorised into upfront local treatment (i.e. metastasectomy or stereotactic radiotherapy), systemic therapy followed by restaging to consider local treatment or systemic therapy alone. The agreement across MDTs was scored to be either absent/poor (<50%), fair (50%-75%), or consensus (≥75%)., Results: A total of 47 MDTs across 16 countries fully discussed the cases (96%). Oligometastatic disease was considered in patients with 1-2 metastases in either the liver, lung, retroperitoneal lymph nodes, adrenal gland, soft tissue or bone (consensus). At follow-up, oligometastatic disease was considered after a median of 18 weeks of systemic therapy when no progression or progression in size only of the oligometastatic lesion(s) was seen (consensus). If at restaging after a median of 18 weeks of systemic therapy the number of lesions progressed, this was not considered as oligometastatic disease (fair agreement). There was no consensus on treatment strategies for oligometastatic disease., Conclusion: A broad consensus on definitions of oligometastatic oesophagogastric cancer was found among MDTs of oesophagogastric cancer expert centres in Europe. However, high practice variability in treatment strategies exists., Competing Interests: Conflict of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Gani reports a research collaboration and travel expenses from Elekta outside the submitted work; Dr. Hawkins reports grants from NIHR Biomedical Research Centre at University College London Hospitals NHS Foundation Trust, outside the submitted work; Dr. Smyth reports personal fees from AMAL Therapeutics, Astellas Pharma, AstraZeneca, Beigene, Five Prime Therapeutics, Merck, Pfizer, Roche, Servier and Zymeworks and institutional funding for clinical trials research from Astra Zeneca, Astellas, Basilea, BMS, Daiichi Sankyo, Roche, Macrogenics and MSD.

Objective: To identify the most prevalent symptoms and those with greatest impact upon health-related quality of life (HRQOL) among esophageal cancer survivors., Background: Long-term symptom burden after esophagectomy, and associations with HRQOL, are poorly understood., Patients and Methods: Between 2010 and 2016, patients from 20 European Centers who underwent esophageal cancer surgery, and were disease-free at least 1 year postoperatively were asked to complete LASER, EORTC-QLQ-C30, and QLQ-OG25 questionnaires. Specific symptom questionnaire items that were associated with poor HRQOL as identified by EORTC QLQ-C30 and QLQ-OG25 were identified by multivariable regression analysis and combined to form a tool., Results: A total of 876 of 1081 invited patients responded to the questionnaire, giving a response rate of 81%. Of these, 66.9% stated in the last 6 months they had symptoms associated with their esophagectomy. Ongoing weight loss was reported by 10.4% of patients, and only 13.8% returned to work with the same activities.Three LASER symptoms were correlated with poor HRQOL on multivariable analysis; pain on scars on chest (odds ratio (OR) 1.27; 95% CI 0.97-1.65), low mood (OR 1.42; 95% CI 1.15-1.77) and reduced energy or activity tolerance (OR 1.37; 95% CI 1.18-1.59). The areas under the curves for the development and validation datasets were 0.81 ± 0.02 and 0.82 ± 0.09 respectively., Conclusion: Two-thirds of patients experience significant symptoms more than 1 year after surgery. The 3 key symptoms associated with poor HRQOL identified in this study should be further validated, and could be used in clinical practice to identify patients who require increased support., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: In recent years, minimally invasive Ivor Lewis (IL) esophagectomy with high intrathoracic anastomosis has emerged as surgical standard of care for esophageal cancer in expert centers. Alongside this process, many divergent technical aspects of this procedure have been devised in different centers. This study aims at achieving international consensus on the surgical steps of IL reconstruction using Delphi methodology., Methods: The expert panel consisted of specialized esophageal surgeons from 8 European countries. During a two-round Delphi process, a detailed analysis and consensus on key steps of intrathoracic gastric tube reconstruction (IL esophagectomy) was performed., Results: Response rates in Delphi rounds 1 and 2 were 100% (22 of 22 experts) and 83.3% (20 of 24 experts), respectively. Three essential technical areas of intrathoracic gastric tube reconstruction were identified: first, vascularization of the gastric conduit, second, gastric mobilization, tube formation and pull-up, and third, anastomotic technique. In addition, 3 main techniques for minimally invasive intrathoracic anastomosis are currently practiced: (i) end-to-side circular stapled, (ii) end-to-side double stapling, and (iii) side-to-side linear stapled technique. The step-by-step procedural analysis unveiled common approaches but also different expert practice., Conclusion: This precise technical description may serve as a clinical guideline for intrathoracic reconstruction after esophagectomy. In addition, the results may aid to harmonize the technical evolution of this complex surgical procedure and thereby facilitate surgical training., (© The Author(s) 2021.

Background: Prognostication for esophageal cancer has traditionally relied on postoperative tissue specimens. This study aimed to use a histologically homogenous cohort to investigate the relationship between clinical, pathological or radiological variables and overall survival in patients undergoing esophagectomy for adenocarcinoma., Methods: A single-centre study of patients who underwent esophagectomy for adenocarcinoma over 10 years in a tertiary centre was performed. By regression analysis, variables available preoperatively and postoperatively were studied for prognostication. The primary outcome was overall survival., Results: 254 cases were analyzed. Over a median follow-up period of 31.8 months (IQR = 42.5), overall survival was 51.5 months (95% confidence interval: 33.0-69.9). According to hazard ratios (HR) for all-cause death, adverse prognostic factors included: a higher postoperative N-stage (HR ≥ 1.29; p ≤ 0.024), histopathological tumor length ≥25 mm (HR = 2.04; p = 0.03), poorer tumor differentiation (HR ≥ 2.86; p ≤ 0.042), and R1 status (HR = 2.33; p = 0.02). A lymph node yield ≥35 was a favorable prognostic factor (HR = 0.022; p < 0.001). Demographic and radiological variables, preoperative TNM stages, postoperative T-stage, and neoadjuvant/adjuvant treatment were not associated with overall survival., Conclusions: This study identifies several postoperatively factors which are available for the prognostication and identifies factors that should not be used to exclude patients from curative surgery., (Copyright © 2020 Elsevier Ltd.

Background: To assess the learning curve for gynecological oncologists in performing upper abdominal surgery for management of patients with advanced epithelial ovarian cancer (EOC)., Methods: Patients undergoing cytoreductive surgery for stage IIIC and IV EOC that required at least one surgical procedure in the upper abdomen were divided in three numerically equal groups: group 1, 2 and 3 that underwent surgery between December 2012 and July 2014, August 2014 to March 2016 and April 2016 to March 2018 respectively., Results: One hundred and twenty-six patients were included. The percentage of patients undergoing primary surgery for group 1, 2 and 3 was 47.6%, 50.0% and 73.8%, respectively (P=0.02). There was significant increase in the percentage of patients undergoing cholecystectomy (P=0.02), resection of disease from porta hepatis (P=0.008), liver capsulectomy (P<0.001), lesser omentectomy (P<0.001) and celiac trunk lymphadenectomy (P<0.001) in the group 3. There was no difference in the percentage of patients undergoing splenectomy, diaphragmatic peritonectomy/resection and gastrectomy. Complete cytoreduction was achieved in 54.8%, 35.7% and 64.3% of patients in group 1, 2 and 3 respectively (P=0.028). There was no significant difference in the occurrence of grade 3-5 complications. Presence of a liver surgeon was required in 9.1%, 5.6% and 0% of cases in group 1, 2 and 3 respectively., Conclusions: The results reflect the evolution of surgical skills in the upper abdomen through the increase in the percentage of patients undergoing primary surgery, with the surgical team undertaking more complex procedures, less involvement of other specialties and simultaneously achieving higher rates of complete cytoreduction.

Objective: To compare publicly available information on aged care systems in 7 countries to determine the degree of transferability for research on aged care between these countries., Design: A cross-country comparative analysis., Setting: Aged care systems in 7 countries classified as liberal welfare states (Australia, Canada, Japan, New Zealand, Switzerland, United Kingdom, and United States)., Measures: This study involved the search and review of international data sets, government reports and national statistics, and relevant peer-reviewed literature. Information was extracted for 24 variables at the macro (societal), meso (organizational), and micro (individual) levels to enable a multilevel comparison of aged care systems in each country., Results: The structured search identified 63 relevant documents. All 7 countries included in the review were overall generally comparable across the 3 domains with some expected variations. Comparison of information was not possible for all variables owing to a paucity of publicly available information reported in a consistent manner. Using Australia as a reference point, Canada and New Zealand were the most comparable with Australia, followed by the United Kingdom, United States, and Switzerland. Japan was the least comparable country with Australia based on the variables considered., Conclusions and Implications: This is the most recent collation and detailed comparison of national-level information on aged care systems in countries classified as liberal welfare states. This information provides policy makers in these countries the data necessary to determine the degree contemporary research findings from another country are transferable to their local aged care system. Efforts to improve the health, well-being, and quality of care for older people continue to be hampered by the overall paucity of consistently reported standardized data to enable valid international comparisons. Optimal use of standardized data also requires developing explicit criteria to describe the key factors to be considered in determining transferability of an intervention from 1 country to another., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

We describe a novel ambulance diversion programme, piloted in Victoria. This article discusses creating increased emergency capacity during surge or disasters by utilising private EDs, tested during a recent thunderstorm asthma disaster and an influenza epidemic. Public hospitals and EDs often run at or over capacity during normal operations. This leaves limited ability to manage surges in demand, resulting in suboptimal outcomes for patients, public ED staff and ambulance services. It is feasible to create surge capacity in private EDs for public ambulance patients. Other states could consider this option to help manage health disasters., (© 2019 Australasian College for Emergency Medicine.)

Goals-of-care discussions aim to establish patient values for shared medical decision-making. These discussions are relevant towards end-of-life as patients may receive non-beneficial treatments if they have never discussed preferences for care. End-of-life care is provided in Emergency Departments (EDs) but little is known regarding ED-led goals-of-care discussions. We aimed to explore practitioner perspectives on goals-of-care discussions for adult ED patients nearing end-of-life. We report the qualitative component of a mixed methods study regarding a 'Goals-of-Care' form in an Australian ED. Eighteen out of 34 doctors who completed the form were interviewed. We characterised ED-led goals-of-care consultations for the first time. Emergency doctors perceive goals-of-care discussions to be relevant to their practice and occurring frequently. They aim to ensure appropriate care is provided prior to review by the admitting team, focusing on limitations of treatment and clarity in the care process. ED doctors felt they could recognise end-of-life and that ED visits often prompt consideration of end-of-life care planning. They wanted long-term practitioners to initiate discussions prior to patient deterioration. There were numerous interpretations of palliative care concepts. Standardisation of language, education, collaboration and further research is required to ensure Emergency practitioners are equipped to facilitate these challenging conversations.

Background: An important parameter for survival in patients with esophageal carcinoma is lymph node status. The distribution of lymph node metastases depends on tumor characteristics such as tumor location, histology, invasion depth, and on neoadjuvant treatment. The exact distribution is unknown. Neoadjuvant treatment and surgical strategy depends on the distribution pattern of nodal metastases but consensus on the extent of lymphadenectomy has not been reached. The aim of this study is to determine the distribution of lymph node metastases in patients with resectable esophageal or gastro-esophageal junction carcinoma in whom a transthoracic esophagectomy with a 2- or 3-field lymphadenectomy is performed. This can be the foundation for a uniform worldwide staging system and establishment of the optimal surgical strategy for esophageal cancer patients., Methods: The TIGER study is an international observational cohort study with 50 participating centers. Patients with a resectable esophageal or gastro-esophageal junction carcinoma in whom a transthoracic esophagectomy with a 2- or 3-field lymphadenectomy is performed in participating centers will be included. All lymph node stations will be excised and separately individually analyzed by pathological examination. The aim is to include 5000 patients. The primary endpoint is the distribution of lymph node metastases in esophageal and esophago-gastric junction carcinoma specimens following transthoracic esophagectomy with at least 2-field lymphadenectomy in relation to tumor histology, tumor location, invasion depth, number of lymph nodes and lymph node metastases, pre-operative diagnostics, neo-adjuvant therapy and (disease free) survival., Discussion: The TIGER study will provide a roadmap of the location of lymph node metastases in relation to tumor histology, tumor location, invasion depth, number of lymph nodes and lymph node metastases, pre-operative diagnostics, neo-adjuvant therapy and survival. Patient-tailored treatment can be developed based on these results, such as the optimal radiation field and extent of lymphadenectomy based on the primary tumor characteristics., Trial Registration: NCT03222895 , date of registration: July 19th, 2017.

Background: Oesophagectomy is a major complex operation associated with significant morbidity and mortality. Epidural analgesia has long been the gold standard postoperative analgesia but is associated with side-effects like hypotension, epidural haematoma and infection. In an attempt to lower morbidity and enhance recovery postoperatively, we have adopted the use of paravertebral catheter analgesia (PVCA) for patients undergoing totally minimal invasive oesophagectomy (TMIO)., Methods: Our objective was to review the current literature about the use of both PVCA and epidural analgesia. In addition, we evaluated the effect of PVCA in a large group of patients undergoing TMIO for cancer. We reviewed the records of 100 consecutive patients who had a TMIO with PVCA, spinal morphine, and PCA. Prospective independent scoring of postoperative pain, length of stay, high-dependency unit (HDU) stay, PVCA failure, the use of patient-controlled analgesia (PCA), and the use of vasoconstrictor medication postoperatively was analysed., Results: One hundred consecutive patients received PVCA with PCA after the TMIO. Catheter related failures occurred in 4 cases. The median pain score over each of the 5 days were 0. The average pain score was highest in the first 24 hours and decreased over the next 4 days postoperatively. The use of PCA was highest in the first 2 days and reduced daily over the subsequent 3 days. Seven patients required rescue analgesia in the form of intercostal nerve (ICN) block. Spinal morphine was successful in 94% of cases. Vasoconstrictors were required in 19% on day 1 and 3% on day 2, postoperatively., Conclusions: Intraoperative placement of PVCA results in good postoperative pain control after a TMIO. This technique is simple, safe, reproducible and with very low failure rates. Therefore, it should be used instead of epidural catheter analgesia., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Objective: There is limited literature to inform the content and format of Goals-of-Care forms, for use by doctors when they are undertaking these important conversations., Methods: This was a prospective, qualitative and quantitative study evaluating the utility of a new 'Goals-of-Care' form to doctors in a private, tertiary ED, used from December 2016 to February 2017 at Cabrini, Melbourne. A Goals-of-Care form was designed, incorporating medical aims of therapy and patient values and preferences. Doctors wishing to complete a Not-for-CPR form were also supplied with the trial Goals-of-Care form. Form use, content and patient progress were followed. Doctors completing a form were invited to interview., Results: Forms were used in 3% of attendances, 120 forms were taken for use and 108 were analysed. The median patient age was 91, 81% were Supportive and Palliative Care Indicators Tool (SPICT) positive and patients had a 48% 6-month mortality. A total of 34 doctors completed the forms, 16 were interviewed (two ED trainees, 11 senior ED doctors and three others). Theme saturation was only achieved for the senior doctors interviewed. Having a Goals-of-Care form was valued by 88% of doctors. The frequency of section use was: Aims-of-Care 91%; Quality-of-Life 75% (the term was polarising); Functional Impairments 35%; and Outcomes of Value 29%. Opinions regarding the ideal content and format varied. Some doctors liked free-text space and others tick-boxes. The median duration of the conversation and documentation was 10 min (interquartile range 6-20 min)., Conclusions: Having a Goals-of-Care form in emergency medicine is supported; the ideal contents of the form was not determined., (© 2018 Australasian College for Emergency Medicine.)

Splenic hemorrhage secondary to retching and vomiting from incarceration of paraesophageal hernia is a rare but life-threatening complication. Clinicians need to be aware of this complication in the event of sudden unexplained hemodynamic instability. Surgical intervention for the hernia is best performed as soon as possible once the patient is stabilized, before complications such as perforation or further bleeding occur. We report two cases of splenic rupture and intraperitoneal bleeding resulting from traction of the gastrosplenic pedicle associated with retching and vomiting from a giant paraesophageal hernia., (Copyright © 2015 The Society of Thoracic Surgeons.

Background and Study Aim: Mucosal neoplasia arising in Barrett's esophagus can be successfully treated with endoscopic mucosal resection (EMR) followed by radiofrequency ablation (RFA). The aim of the study was to compare clinical outcomes of patients with high grade dysplasia (HGD) or intramucosal cancer (IMC) at baseline from the United Kingdom RFA registry., Patients and Methods: Prior to RFA, visible lesions and nodularity were removed entirely by EMR. Thereafter, patients underwent RFA every 3 months until all visible Barrett's mucosa was ablated or cancer developed (end points). Biopsies were taken at 12 months or when end points were reached., Results: A total of 515 patients, 384 with HGD and 131 with IMC, completed treatment. Prior to RFA, EMR was performed for visible lesions more frequently in the IMC cohort than in HGD patients (77 % vs. 47 %; P < 0.0001). The 12-month complete response for dysplasia and intestinal metaplasia were almost identical in the two cohorts (HGD 88 % and 76 %, respectively; IMC 87 % and 75 %, respectively; P = 0.7). Progression to invasive cancer was not significantly different at 12 months (HGD 1.8 %, IMC 3.8 %; P = 0.19). A trend towards slightly worse medium-term durability may be emerging in IMC patients (P = 0.08). In IMC, EMR followed by RFA was definitely associated with superior durability compared with RFA alone (P = 0.01)., Conclusion: The Registry reports on endoscopic therapy for Barrett's neoplasia, representing real-life outcomes. Patients with IMC were more likely to have visible lesions requiring initial EMR than those with HGD, and may carry a higher risk of cancer progression in the medium term. The data consolidate the approach to ensuring that these patients undergo thorough endoscopic work-up, including EMR prior to RFA when necessary., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: The timing of the risk factors cigarette smoking, alcohol and obesity in the development of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) is unclear., Aims: To investigate these exposures in the aetiology of BE and EAC in the same population., Methods: The cohort included 24,068 men and women, aged 39-79 years, recruited between 1993 and 1997 into the prospective EPIC-Norfolk Study who provided information on anthropometry, smoking and alcohol intake. The cohort was monitored until December 2008 and incident cases identified., Results: One hundred and four participants were diagnosed with BE and 66 with EAC. A body mass index (BMI) above 23 kg/m(2) was associated with a greater risk of BE [BMI ≥23 vs. 18.5 to <23, hazard ratio (HR) 3.73, 95 % CI 1.37-10.16], and within a normal BMI, the risk was greater in the higher category (HR 3.76, 95 % CI 1.30-10.85, BMI 23-25 vs. 18.5 to >23 kg/m(2)). Neither smoking nor alcohol intake were associated with risk for BE. For EAC, all BMI categories were associated with risk, although statistically significant for only the highest (BMI >35 vs. BMI 18.5 to <23, HR 4.95, 95 % CI 1.11-22.17). The risk was greater in the higher category of a normal BMI (HR 2.73, 95 % CI 0.93-8.00, p = 0.07, BMI 23-25 vs. 18.5 to >23 kg/m(2)). There was an inverse association with ≥7 units alcohol/week (HR 0.51, 95 % CI 0.29-0.88) and with wine (HR 0.49, 95 % CI 0.23-1.04, p = 0.06, drinkers vs. non-drinkers)., Conclusions: Obesity may be involved early in carcinogenesis and the association with EAC and wine should be explored. The data have implications for aetiological investigations and prevention strategies.

Background/aims: Gastrointestinal stromal tumours are the most frequently occurring sarcoma of the gastrointestinal tract. Current treatment involves complete resection although the surgical or pathological margin required remains unclear. In this study we aimed to examine the risk of local and distant recurrence following laparoscopic resection., Methods: From a prospective tumour database, we identified and risk stratified primary non-metastatic tumours treated by laparoscopic resection from 2002-2012. Local technique involves allowing a 1 cm margin for resection. We then identified all cases of tumour recurrence and tumour related death in order to calculate overall survival, freedom from GIST recurrence and disease-specific survival respectively., Results: 90 patients were identified with a median follow-up of 3.9 years (range 1 week to 12.3 years). Five-year freedom from GIST recurrence and disease-specific survival rates in the high-risk group stood at 0.63 and 0.90. In the moderate-risk group these figures stood at 0.61 and 0.80 respectively. The low- and very-low-risk groups had a 10-year recurrence-free survival of 100% with no incidences of tumour-related recurrence. There were no local recurrences seen in any group at up to 10 years., Conclusion: The low recurrence rate suggests that these tumours can safely be treated laparoscopically with an R0 resection using a macroscopic surgical margin of 10 mm. Disease-specific survival was high. This may reflect earlier detection and the use of adjuvant imatinib.

Background & Aims: Patients with Barrett's esophagus (BE) and high-grade dysplasia (HGD) or early neoplasia increasingly receive endoscopic mucosal resection and radiofrequency ablation (RFA) therapy. We analyzed data from a UK registry that follows the outcomes of patients with BE who have undergone RFA for neoplasia., Methods: We collected data on 335 patients with BE and neoplasia (72% with HGD, 24% with intramucosal cancer, 4% with low-grade dysplasia [mean age, 69 years; 81% male]), treated at 19 centers in the United Kingdom from July 2008 through August 2012. Mean length of BE segments was 5.8 cm (range, 1-20 cm). Patients' nodules were removed by endoscopic mucosal resection, and the patients then underwent RFA every 3 months until all areas of BE were ablated or cancer developed. Biopsies were collected 12 months after the first RFA; clearance of HGD, dysplasia, and BE were assessed., Results: HGD was cleared from 86% of patients, all dysplasia from 81%, and BE from 62% at the 12-month time point, after a mean of 2.5 (range, 2-6) RFA procedures. Complete reversal dysplasia was 15% less likely for every 1-cm increment in BE length (odds ratio = 1.156; SE = 0.048; 95% confidence interval: 1.07-1.26; P < .001). Endoscopic mucosal resection before RFA did not provide any benefit. Invasive cancer developed in 10 patients (3%) by the 12-month time point and disease had progressed in 17 patients (5.1%) after a median follow-up time of 19 months. Symptomatic strictures developed in 9% of patients and were treated by endoscopic dilatation. Nineteen months after therapy began, 94% of patients remained clear of dysplasia., Conclusions: We analyzed data from a large series of patients in the United Kingdom who underwent RFA for BE-related neoplasia and found that by 12 months after treatment, dysplasia was cleared from 81%.
