Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Due to the luminal nature of the disease, esophageal cancer diagnosis and treatment is challenging. Majority of the patients usually present with dysphagia, at which point the disease is often locally advanced. Diagnosis and treatment need a multidisciplinary approach which often involves endoscopy, imaging services, oncology services, surgical services, and critical care services. Surgery is associated with significant morbidity and mortality and care should be domiciled in high-volume centers. Training and mentorship are key to building capacity for esophageal cancer care.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
BACKGROUND Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting. METHODS Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.). RESULTS Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter 'no major postoperative complication' had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome. CONCLUSION Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
Background and study aims Dysphagia from esophageal cancer may be palliated with self-expanding metallic stents (SEMS). Controversy exists about the use of dilation before SEMS deployment. Patients and methods We performed a retrospective cohort study of patients who had SEMS placement without fluoroscopy for palliation at Tenwek Hospital in Bomet, Kenya between January 1999 and April 2019. The primary outcome was any serious adverse event (AE) (chest pain, stent migration, perforation, bleeding, or all-cause mortality) within 30 days of the procedure. Various demographic and clinical characteristics, and procedural details, were examined as risk factors. Technical success, defined as correct SEMS placement, and clinical success, defined as dysphagia score improvement without 30-day mortality, were examined. Results A total of 3823 patients underwent SEMS placement, with 2844 (74.4 %) placed in the second decade of the study. Technical and clinical success were achieved in 97.2 % and 95.5 %, respectively, with mean dysphagia scores improving from 3.4 (SD 0.6) to 0.9 (SD 1.3) post-stent placement. AEs occurred in 169 patients (4.4 %). AEs, specifically perforations, were associated with dilation to greater than 36F in the first decade. Perforation rates decreased from the first (4.1 %) to the second decade (0.2 %). Only 30% had complete 30-day follow-up data. Conclusions SEMS placement is a safe, effective method of palliating malignant dysphagia, with low rates of AEs and 30-day mortality and high rates of clinical and technical success. Dilation can facilitate placement of SEMS without fluoroscopy but should not be performed above 36F due to the risk of perforation.

Abstract
Objective We aimed to determine the impact of a standardized curriculum on learning outcomes for surgical trainees in East, Central, and Southern Africa (ECSA). Background As surgical education expands throughout ECSA, there is a recognized need for a standardized curriculum. We previously described the design of a novel, large-scale, flipped-classroom, surgical curriculum for trainees in ECSA. Methods In January 2020, the first year of curricular content for trainees of the College of Surgeons of ECSA was released, containing 11 monthly thematic topics, each with 2 to 5 weekly modular subtopics. We aimed to evaluate 3 outcomes utilizing data sources incorporated into the curriculum structure. Learner engagement was assessed by the number of trainees completing curriculum topics. User experience was evaluated using quantitative and qualitative feedback responses to embedded surveys for each content week. Curriculum impact on trainee examination performance was assessed by comparing certification examination scores stratified by the number of curricular topics each trainee completed. Results Two hundred seventy-one trainees (96%) in 17 countries accessed at least 1 weekly module. Trainees completed a median of 9 topics (interquartile range: 6-10). The feedback survey response rate was 92% (5742/6233). Quantitative and qualitative responses were positive in overall module value (93.7% + 2.6%), amount of learning experienced (97.9% + 1.4%), confidence in achieving learning objectives (97.1% + 2.4%), and ease of use of the module (77.6% + 5.98%). Topic-related certification examination performance improved significantly with increased completion of thematic topics. Conclusions A standardized surgical curriculum in ECSA demonstrated excellent trainee usage, positive feedback, and improved examination scores.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is a major cause of cancer morbidity and mortality in Eastern Africa. The majority of patients with ESCC in Eastern Africa present with advanced disease at the time of diagnosis. Several palliative interventions for ESCC are currently in use within the region, including chemotherapy, radiation therapy with and without chemotherapy, and esophageal stenting with self-expandable metallic stents; however, the comparative effectiveness of these interventions in a low resource setting has yet to be examined. Methods This prospective, observational, multi-center, open cohort study aims to describe the therapeutic landscape of ESCC in Eastern Africa and investigate the outcomes of different treatment strategies within the region. The 4.5-year study will recruit at a total of six sites in Kenya, Malawi and Tanzania (Ocean Road Cancer Institute and Muhimbili National Hospital in Dar es Salaam, Tanzania; Kilimanjaro Christian Medical Center in Moshi, Tanzania; Tenwek Hospital in Bomet, Kenya; Moi Teaching and Referral Hospital in Eldoret, Kenya; and Kamuzu Central Hospital in Lilongwe, Malawi). Treatment outcomes that will be evaluated include overall survival, quality of life (QOL) and safety. All patients (≥18 years old) who present to participating sites with a histopathologically-confirmed or presumptive clinical diagnosis of ESCC based on endoscopy or barium swallow will be recruited to participate. Key clinical and treatment-related data including standardized QOL metrics will be collected at study enrollment, 1 month following treatment, 3 months following treatment, and thereafter at 3-month intervals until death. Vital status and QOL data will be collected through mobile phone outreach. Discussion This study will be the first study to prospectively compare ESCC treatment strategies in Eastern Africa, and the first to investigate QOL benefits associated with different treatments in sub-Saharan Africa. Findings from this study will help define optimal management strategies for ESCC in Eastern Africa and other resource-limited settings and will serve as a benchmark for future research. Trial registration This study was retrospectively registered with the ClinicalTrials.gov database on December 15, 2021, NCT05177393. Supplementary Information The online version contains supplementary material available at 10.1186/s12885-021-09124-5.

Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
Background and study aims Limited evidence suggests that endoscopy capacity in sub-Saharan Africa is insufficient to meet the levels of gastrointestinal disease. We aimed to quantify the human and material resources for endoscopy services in eastern African countries, and to identify barriers to expanding endoscopy capacity. Patients and methods In partnership with national professional societies, digestive healthcare professionals in participating countries were invited to complete an online survey between August 2018 and August 2020. Results Of 344 digestive healthcare professionals in Ethiopia, Kenya, Malawi, and Zambia, 87 (25.3 %) completed the survey, reporting data for 91 healthcare facilities and identifying 20 additional facilities. Most respondents (73.6 %) perform endoscopy and 59.8 % perform at least one therapeutic modality. Facilities have a median of two functioning gastroscopes and one functioning colonoscope each. Overall endoscopy capacity, adjusted for non-response and additional facilities, includes 0.12 endoscopists, 0.12 gastroscopes, and 0.09 colonoscopes per 100,000 population in the participating countries. Adjusted maximum upper gastrointestinal and lower gastrointestinal endoscopic capacity were 106 and 45 procedures per 100,000 persons per year, respectively. These values are 1 % to 10 % of those reported from resource-rich countries. Most respondents identified a lack of endoscopic equipment, lack of trained endoscopists and costs as barriers to provision of endoscopy services. Conclusions Endoscopy capacity is severely limited in eastern sub-Saharan Africa, despite a high burden of gastrointestinal disease. Expanding capacity requires investment in additional human and material resources, and technological innovations that improve the cost and sustainability of endoscopic services.

Abstract
PURPOSE At the 12th meeting of AORTIC (African Organization for Research and Training in Cancer) in Maputo, Mozambique, held between November 5 and November 8, 2019, a special workshop was organized to focus on the need for collaboration and coordination between governments and health systems in Africa with academic, industry, association, and other nongovernmental organizations to effect sustainable positive change for the care of patients with cancer. METHODS Representatives from seven different projects in Africa presented implementation science and demonstration projects of their to date efforts in cancer system improvement including patient access, South-South partnerships, in-country specialized training, palliative care consortium, treatment outcomes, and focused pathology and diagnostic capacity building. Key partners of the various projects served as moderators and commentators during the session. RESULTS From across all the presentations, lessons learned and exemplary evidence of the value of partnerships were gathered and summarized. CONCLUSION The concluding synthesis of the presentations determined that with the broad needs across cancer requiring in-depth expertise at each point on a patient's journey, no single organization can effect change alone. Multipartner collaborations not only should be the norm but should also be coordinated so that efforts are not duplicated and maximum patient access to cancer diagnosis and care is achieved.

Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is a leading modality for treatment of biliary and pancreatic disease but is not widely available in sub-Saharan Africa. We aimed to assess the development and outcomes of an ERCP service in southwestern Kenya, including case volumes, success rates, infrastructure, and training. METHODS We conducted a retrospective review of all ERCPs performed at Tenwek Hospital in Bomet, Kenya between January 1, 2011 and March 31, 2020. RESULTS In total 277 ERCP procedures were attempted during the study period. The commonest indication was obstructive jaundice: 91 patients (32.9%) had malignancy and 85 (30.7%) had choledocholithiasis. Overall clinical success rate was 76.1% and was the highest in patients with biliary stones (81.2%) and lowest in those with tumors (73.5%) (p = 0.094). Procedure-related adverse events occurred in 11.9%, including post-ERCP pancreatitis in 3.6%, with a procedure-related mortality rate of 1.4%. Annual case volumes increased, and mean procedure duration decreased from 162 to 115 min (p = 0.0007) over time. A previously- rained endoscopist initially performed all cases; two staff endoscopists were trained in ERCP during the study period, performing 130 and 89 ERCPs during training, with clinical success rates of 84% and 74% during their subsequent independent practice. CONCLUSION An ERCP service can be successfully developed at a rural African hospital, with acceptable success and adverse event rates. Biliary obstruction due to stones or tumors are the most common findings. While a previously trained endoscopist should initiate and champion the service, staff endoscopists can be successfully trained despite limited case volumes.

Abstract
Esophageal cancer (EC) is a leading cause of cancer morbidity and mortality in Africa. Despite the high burden of disease, optimal management strategies for EC in resource-constrained settings have yet to be established. This systematic review evaluates the literature on treatments for EC throughout Africa and compares the efficacy and safety of varying treatment strategies in this context (PROSPERO CRD42017071546). PubMed, Embase and African Index Medicus were searched for studies published on treatment strategies for EC in Africa from 1980 to 2020. Searches were supplemented by examining bibliographies of included studies and relevant conference proceedings. Methodological quality/risk of bias was assessed using the Cochrane Risk-of-Bias tool and the Newcastle-Ottawa Scale. Forty-six studies were included. Case series constituted the majority of studies: 13 were case series reporting on outcomes of esophagectomies, 17 on palliative luminal or surgical interventions, four on radiotherapy and three on concurrent chemoradiation. Nine randomized controlled trials were identified, of which four prospectively compared different treatment modalities (one investigating radiotherapy vs chemoradiation, three evaluating rigid plastic stents vs other treatments). This review summarizes the research on EC treatments in Africa published over the last four decades and outlines critical gaps in knowledge related to management in this context. Areas in need of further research include (a) evaluation of the safety and efficacy of neoadjuvant therapy in patients with locally advanced disease; (b) strategies to improve long-term survival in patients treated with definitive chemoradiation; and (c) the comparative effectiveness of modern palliative interventions, focusing on quality of life and survival as outcome measures.

Abstract
Trauma constitutes a significant cause of death and disability globally. The vast majority -about 95%, of the 5.8 million deaths each year, occur in low-and-middle-income countries (LMICs) 3-6. This includes almost 1 million children. The resource-adapted introduction of trauma care protocols, regionalized care and the growth specialized centers for trauma care within each LMIC are key to improved outcomes and the lowering of trauma-related morbidity and mortality globally. Resource limitations in LMICs make it necessary to develop injury prevention strategies and optimize the use of locally available resources when injury prevention measures fail. This will lead to the achievement of the best possible outcomes for critically ill and injured children. A commitment by the governments in LMICs working alone or in collaboration with international non-governmental organizations (NGOs) to provide adequate healthcare to their citizens is also crucial to improved survival after major trauma. The increase in global conflicts also has significantly deleterious effects on children, and governments and international organizations like the United Nations have a significant role to play in reducing these. This review details the evaluation and management of traumatic injuries in pediatric patients and gives some recommendations for improvements to trauma care in LMICs.

Abstract
The objective of this study was to assess the outcomes for patients with human immunodeficiency virus (HIV) and acquired immune deficiency virus (AIDS) who had esophagectomy done for both benign and malignant conditions. A retrospective chart review of patients with HIV and AIDS undergoing esophagectomy at a rural referral hospital was done for the period of 2009-2014. Patient postoperative complications, outcomes, and follow-up data were charted. All procedures were done by a single lead surgeon. Nine patients met the study criteria, 7 of whom had esophageal cancer, and 2 with strictures. Four patients had received nutritional self-expanding metal stent preoperatively. The mean stent duration was 61 days. Three patients had been on antiretroviral therapy before surgery. Preoperative CD4 counts were available in 7 patients. Eight patients underwent a 3-field esophagectomy and 1 was unresectable. Seven of these patients had successful outcomes, with varying follow-up times. One patient died post procedure while in the hospital. Complications included stricture and anastomotic leak. Although HIV-positive patients face increased risk during surgical procedures, this status should not be a firm contraindication to surgery. Quality nutritional status, antiretroviral use, and overall CD4 count levels remain important parameters in considering surgical treatment for these patients. With careful patient evaluation and planning, esophagectomy in an HIV and AIDS setting is feasible with successful outcomes.

Abstract
Abstract 44 Background: Esophageal cancer is the sixth leading cause of cancer death worldwide. It kills 400,000 people every year, most of whom live in two distinct geographic bands across central Asia and along the eastern Africa corridor that extends from Ethiopia to South Africa. In these high-risk areas, nearly all cases are esophageal squamous cell carcinoma (ESCC). Our group and others have performed many etiologic, genetic, and early detection and treatment studies of ESCC in central Asia, but this disease remains essentially unstudied in eastern Africa. Over the past few years, several groups have begun quality studies of ESCC in Africa, including case-control studies in Dar es Salaam, Tanzania (University of California, San Francisco, and Muhimbili University of Health and Allied Sciences); Eldoret, Kenya (International Agency for Research on Cancer and Moi University); Moshi, Tanzania (International Agency for Research on Cancer and Kilimanjaro Clinical Research Institute); Bomet, Kenya (National Cancer Institute and Tenwek Hospital); and Lilongwe, Malawi (National Cancer Institute and the UNC-Malawi Project). In November 2015, these groups met and decided to create the African Esophageal Cancer Consortium. The goals of the consortium are to raise awareness of the importance of ESCC in Africa, to coordinate etiologic and molecular studies of ESCC in high-risk populations, and to facilitate provision of therapeutic training and equipment aimed to improve survival and quality of life. Methods: The first coordinated activity was to standardize questionnaires so that data can later be compared and combined. The consortium has embraced mobile health technologies through development of an mHealth app for real-time data capture on a phone or tablet and to collect harmonized data from the outset, increase efficiency, eliminate transcription mistakes, and allow real-time quality control and supervision of field activities from any location. Results: The consortium held its second annual meeting in September 2016. At this meeting, the five member sites affirmed their commitment to the consortium and the first study coordinator was named. Conclusion: Case-control studies in Moshi, Bomet, and Lilongwe are using the mobile app. A case-control study in Dar es Salaam is complete, with results pending. Coordinated genome-wide association and genomic studies are planned, with collection of biospecimens from multiple sites. The consortium is actively working with partners in China to provide affordable stents in Africa for palliative ESCC treatment as well as to secure training to safely and effectively place stents. Annual meetings will continue to follow-up on progress and develop new initiatives. AUTHORS' DISCLOSURES OF POTENTIAL CONFLICTS OF INTEREST No COIs from the authors.

Abstract
Traumatic injuries are a significant cause of death and disability worldwide. The vast majority of these injuries occur in low- and middle-income countries (LMICs). Attention to protocolized care and adaptations to treatments based on availability of resources, regionalization of care, and the development of centers of excellence within each LMIC are crucial to improving outcomes and lowering trauma-related morbidity and mortality worldwide. Given limitations in the availability of the resources necessary to provide the levels of care found in high-income countries, strategies to prevent trauma and make the best use of available resources when prevention fails, and thus achieve the best possible outcomes for injured and critically ill children, are vital. Overall, a commitment on the part of governments in LMICs to the provision of adequate health care services to their populations will improve the outcomes of injured children. This review details the evaluation and management of traumatic injuries in pediatric patients and gives some recommendations for improvements to trauma care in LMICs.

Abstract
GOALS To assess the effect of esophageal stent diameter on outcomes of patients with malignant esophageal obstruction. BACKGROUND Esophageal self-expandable metal stents (SEMS) effectively palliate dysphagia due to malignancy, but the best stent diameter is unknown. STUDY A prospective randomized trial was conducted at a regional referral hospital. One hundred persons with unresectable esophageal cancer were enrolled, randomized to receive a SEMS of either 18 or 23 mm shaft diameter but identical design, and followed until death. Outcome measurements were dysphagia score, adverse events, endoscopic reintervention, and survival. RESULTS The study arms were evenly matched. Dysphagia resolved after stent placement in 95% in both groups. After 6 months the cumulative incidence of recurrent dysphagia was 38% (95% CI 18%-53%) versus 47% (26%-63%) in the small-diameter versus large-diameter groups, respectively (P=0.23). The cumulative incidence of adverse events was 57% in both groups at 6 months, with trends toward more frequent gastrointestinal bleeding and esophago-respiratory fistula in the large-diameter group, and more frequent stent migration, stent occlusion, and endoscopic reintervention in the small-diameter group. There was a trend toward longer survival in the small-diameter group (median survival, 5.9 vs. 3 mo; P=0.10). Higher initial performance status score and female gender were associated with improved survival. Limitations include enrollment of only 100 (of a planned 200) persons and incomplete follow-up of some participants. CONCLUSIONS Small-diameter and large-diameter esophageal SEMS provided similar palliation of dysphagia due to esophageal cancer. The overall incidence of adverse events was not affected by stent diameter, but there was a trend toward longer survival with small-diameter stents (Clinical trial registration number: NCT01894763).

Abstract
BACKGROUND Esophageal cancer is unusually frequent in Western Kenya, despite the low prevalence of classical risk factors such as heavy drinking and tobacco smoking. Among Kenyans consumption of fermented milk is an old tradition. Our hypothesis is that alcohol and acetaldehyde are produced during the fermentation process and that their carcinogenic potential contributes to the high incidence of esophageal cancer. METHODS Eight samples of mursik milk starter cultures were collected from different Kalenjin families in the Rift Valley province, Western Kenya. A protocol provided by the families was used for milk fermentation. Ethanol and acetaldehyde levels were measured by gas chromatography. The microbial flora in starter cultures was identified by 16S and 18S sequencing. RESULTS 7/8 starter cultures produced mutagenic (>100 μmol/L) levels of acetaldehyde and 4/8 starter cultures produced more than 1,000 μmol/L of acetaldehyde. The highest alcohol levels (mean 79.4 mmol/L) were detected in the four fermented milks with highest acetaldehyde production. The mean number of microbial species in the starter cultures was 5 (range 2-8). Yeasts were identified in all starter cultures (mean 1.5 species/milk) but their proportion of the total microbial count varied markedly (mean 35%, range 7%-90%). A combination of yeast and lactobacilli, especially Candida krusei with Lactobacillus kefiri, with the exclusion of other species, seemed to correlate with higher acetaldehyde and ethanol levels. CONCLUSIONS Significant levels of ethanol and acetaldehyde were produced during mursik fermentation. IMPACT When ingested several times daily the repeated exposure to carcinogenic levels of acetaldehyde may contribute to esophageal carcinogenesis.
