BACKGROUND: Racial disparities currently exist for the utilization rate of esophagectomy for Black patients with operable esophageal carcinoma. METHODS: A total of 37 271 cases with the American Joint Committee on Cancer clinical stage I, II, and III esophageal carcinoma that were reported to the National Cancer Database were analyzed between 2004 and 2016. A multivariable-adjusted logistic regression model was used to evaluate differences in the odds ratio of esophagectomy not being recommended based on race. Kaplan-Meier curves and log-rank tests were used to evaluate differences in overall survival. Propensity score methodology with inverse probability of treatment weighting (IPTW) was used to balance baseline differences in patient demographics. RESULTS: After IPTW adjustment, we identified 30 552 White patients and 3529 Black patients with clinical stage I-III esophageal carcinoma. Black patients had three times greater odds of not being recommended for esophagectomy (odds ratio: 3.03, 95% confidence interval: 2.67-3.43, p < 0.0001) compared to White patients. Black patients demonstrated significantly worse 3- and 5-year overall survival rates compared to White patients (log-rank p < 0.0001). CONCLUSION: Black patients with clinical stage I-III esophageal cancer were significantly less likely to be recommended for esophagectomy even after adjusting for baseline demographic covariates compared to White patients.

BACKGROUND: Robotic esophagectomies are increasingly common and are reported to have superior outcomes compared with an open approach; however, it is unclear if all institutions can achieve such outcomes. We hypothesize that early adopters of robotic technique would have improved short-term outcomes. METHODS: The National Cancer Database (2010-2016) was used to identify robotic esophagectomies. Early adopters were defined as programs which performed robotic esophagectomies in 2010-2011, late adopters in 2012-2013. Outcomes of esophagectomies performed between 2014 and 2016 were compared and included length of stay, number of lymph nodes evaluated, readmission, conversion rate, and 90-day mortality. Multivariable regressions, accounting for robotic esophagectomy volume, were used to control for confounding factors. RESULTS: There were 37 early adopters and 35 late adopters. Between 2014 and 2016, 683 robotic esophagectomies were performed: 446 (65.3%) by early adopters and 237 (34.7%) by late adopters. Early adopters were more likely to be academic programs (96.2 versus 72.8%, P < 0.01). Other clinical and demographic variables were similar. Late adopters were found to have decreased a number of lymph nodes evaluated (coefficient -2.407, P = 0.004) compared with early adopters. There were no significant differences in length of stay, readmissions, rate of positive margins, conversion from robotic to open, or 90-day mortality. CONCLUSIONS: When accounting for robotic esophagectomy volume, late adoption of robotic esophagectomy was associated with a reduced lymph node harvest, but other postoperative outcomes were similar. These data suggest that programs can safely start new robotic esophagectomy programs, but must ensure an adequate case load.

BACKGROUND: Esophagectomy practices have evolved over time in response to new technologies and refinements in technique. Using the National Safety and Quality Improvement Program (NSQIP) database, we aimed to describe trends for esophagectomy in terms of approach, surgeon specialty, and associated outcomes. MATERIALS AND METHODS: Adult patients undergoing esophagectomy were identified within the 2007-2017 NSQIP database. The proportion of cases performed using different approaches was trended over time. Outcomes were compared with chi-squared and t-tests. Multivariate logistic regression was used to identify factors associated with outcomes and provide risk-adjusted measures. RESULTS: A total of 10,383 esophagectomies were included; 6347 (61.1%) were performed for cancer. The proportion of esophagectomies performed via the Ivor Lewis approach (ILE) increased between 2007 (37.0%) and 2017 (62.4%). Simultaneously, transhiatal esophagectomies (THEs) decreased from 41.1% to 21.5% (P < 0.001). THE was more frequently performed in patients with higher baseline probability of mortality (2.3% versus 2.0%, P < 0.001) and morbidity (32.2% versus. 28.7%, P < 0.001). The percentage performed with cardiothoracic surgeons increased from 0.8% in 2007 to 50.3% in 2017 (P < 0.001). The risk-adjusted complication rate was 45% for THE, 40% for ILE, and 50% for McKeown (MCK) esophagectomy (P < 0.001). The risk-adjusted rate of surgical site infection was 17.3% for THE, 13.1% for ILE, and 19% for MCK (P = 0.001). Within risk-adjusted analysis, surgical approach was not associated with complications. CONCLUSIONS: ILE has emerged as the predominant approach for esophagectomy nationwide among NSQIP-participating institutions and may be associated with lower complication rates than THE. The use of MCK esophagectomy has remained stable but is associated with increased complications.

OBJECTIVES: Strong evidence links obesity to esophageal cancer (EC), gastric cancer (GC), colorectal cancer (CRC), and pancreatic cancer (PC). However, national-level studies testing the link between obesity and recent temporal trends in the incidence of these cancers are lacking. METHODS: We queried the Surveillance, Epidemiology, and End Results (SEER) to identify the incidence of EC, GC, CRC, and PC. Cancer surgeries stratified by obesity (body mass index ≥30 kg/m) were obtained from the National Inpatient Sample (NIS). We quantified trends in cancer incidence and resections in 2002-2013, across age groups, using the average annual percent change (AAPC). RESULTS: The incidence of CRC and GC increased in the 20-49 year age group (AAPC +1.5% and +0.7%, respectively, P < 0.001) and across all ages for PC. Conversely, the incidence of CRC and GC decreased in patients 50 years or older and all adults for EC. According to the NIS, the number of patients with obesity undergoing CRC resections increased in all ages (highest AAPC was +15.3% in the 18-49 year age group with rectal cancer, P = 0.047). This trend was opposite to a general decrease in nonobese patients undergoing CRC resections. Furthermore, EC, GC, and PC resections only increased in adults 50 years or older with obesity. DISCUSSION: Despite a temporal rise in young-onset CRC, GC, and PC, we only identify a corresponding increase in young adults with obesity undergoing CRC resections. These data support a hypothesis that the early onset of obesity may be shifting the risk of CRC to a younger age.

Esophageal cancer surgery originated in the early 20(th) century. However, the true meaning of trans-thoracic esophagectomy and digestive tract reconstruction began in the 1930s. Almost at the same time, Japan and Western countries began the surgical exploration of esophageal cancer. Based on the pathological type of esophageal cancer in Asia, squamous cell carcinoma is the majority, and its biological characteristics and treatment strategies are different from those of European and American patients. After more than eighty years of development, the surgical treatment of esophageal cancer in Japan has been developed from the initial attempt, deep cultivation practice to the pursuit of excellence, and explored a set of more advanced surgical techniques and diagnostic strategies, which is unique in the world. On the basis of the establishment of the Japanese Society of Esophagus, Japanese scholars have developed and irregularly updated the Japanese Classification of Esophageal Cancer and published the professional academic journal Esophagus. The Japanese Clinical Oncology Group organized a number of phase â ¢ clinical studies on esophageal cancer, providing strong evidence for the diagnosis and treatment of esophageal squamous carcinoma. Focused on the origin, development, current situation and future of esophageal cancer surgery in Japan, this paper summarized the development of esophageal cancer surgery in Japan through literature review, interviews with senior experts and Hot topics of esophageal cancer surgery-questionnaire survey of Japanese experts.

BACKGROUND: Initial adoption of minimally invasive esophagectomy (MIE) began in the late 1990s but its surgical technique, perioperative management, and outcome continues to evolve. METHODS: The aim of this study was to examine the evolving changes in the technique, outcome, and new strategies in management of postoperative leaks after MIE was performed at a single institution over a two-decade period. A retrospective chart review of 75 MIE operations was performed between November 2011 and September 2018 and this was compared to the initial series of 104 MIE operations performed by the same group between 1998 and 2007. Operative technique, outcomes, and management strategies of leaks were compared. RESULTS: There were 65 males (86.7%) with an average age of 61 years. The laparoscopic/thoracoscopic Ivor Lewis esophagectomy became the preferred MIE approach (49% of cases in the initial vs. 95% in the current series). Compared to the initial case series, there was no significant difference in median length of stay (8 vs. 8 days), major complications (12.5% vs. 14.7%, p = 0.68), incidence of leak (9.6% vs. 10.6%, p = 0.82), anastomotic stricture (26% vs. 32.0%, p = 0.38), or in-hospital mortality (2.9% vs. 2.6%, p = 0.47). Management of esophageal leaks has changed from primarily thoracotomy ± diversion initially (50% of leak cases) to endoscopic stenting ± laparoscopy/thoracoscopy currently (87.5% of leak cases). CONCLUSION: In a single-institutional series of MIE over two decades, there was a shift toward a preference for the laparoscopic/thoracoscopic Ivor Lewis approach with similar outcomes. The management of postoperative leaks drastically changed with predilection toward minimally invasive option with endoscopic drainage and stenting.

BACKGROUND: The management of proximal esophageal cancer differs from that of tumors located in the mid and lower part of the esophagus due to the close vicinity of vital structures. Non-surgical treatment options like radiotherapy and definitive chemoradiation (CRT) have been implemented. The trends in (non-)surgical treatment and its impact on overall survival (OS) in patients with proximal esophageal cancer are unclear, related to its rare disease status. To optimize treatment strategies and counseling of patients with proximal esophageal cancer, it is therefore essential to gain more insight through real-life studies. AIM: To establish trends in treatment and OS in patients with proximal esophageal cancer. METHODS: In this population-based study, patients with proximal esophageal cancer diagnosed between 1989 and 2014 were identified in the Netherlands Cancer Registry. The proximal esophagus consists of the cervical esophagus and the upper thoracic section, extending to 24 cm from the incisors. Trends in radiotherapy, chemotherapy, and surgery, and OS were assessed. Analyses were stratified by presence of distant metastasis. Multivariable Cox proportional hazards regression analyses was performed to assess the effect of period of diagnosis on OS, adjusted for patient, tumor, and treatment characteristics. RESULTS: In total, 2783 patients were included. Over the study period, the use of radiotherapy, resection, and CRT in non-metastatic disease changed from 53%, 23%, and 1% in 1989-1994 to 21%, 9%, and 49% in 2010-2014, respectively. In metastatic disease, the use of chemotherapy and radiotherapy increased over time. Median OS of the total population increased from 7.3 mo [95% confidence interval (CI): 6.4-8.1] in 1989-1994 to 9.5 mo (95%CI: 8.1-10.8) in 2010-2014 (logrank P < 0.001). In non-metastatic disease, 5-year OS rates improved from 5% (95%CI: 3%-7%) in 1989-1994 to 13% (95%CI: 9%-17%) in 2010-2014 (logrank P < 0.001). Multivariable regression analysis demonstrated a significant treatment effect over time on survival. In metastatic disease, median OS was 3.8 mo (95%CI: 2.5-5.1) in 1989-1994, and 5.1 mo (95%CI: 4.3-5.9) in 2010-2014 (logrank P = 0.26). CONCLUSION: OS significantly improved in non-metastatic proximal esophageal cancer, likely to be associated with an increased use of CRT. Patterns in metastatic disease did not change significantly over time.

OBJECTIVE: The purpose of this study was to explore nationwide trends in treatment and outcomes of T1N0 esophageal cancer. BACKGROUND: Endoscopic treatment has become an accepted option for early-stage esophageal cancer, but nationwide utilization rates and outcomes are unknown. METHODS: T1N0 esophageal cancers were identified in the National Cancer Database from 2004 to 2014. We assessed trends in treatment; compared endoscopic therapy, esophagectomy, chemoradiation, and no treatment; and performed a subgroup analysis of T1a and T1b patients from 2010 to 2014 (AJCC 7). RESULTS: A total of 12,383 patients with clinical T1N0 esophageal cancer were analyzed. Over a decade, use of endoscopic therapy increased from 12.7% to 33.6%, whereas chemoradiation and esophagectomy decreased, P < 0.01. The rise in endoscopic treatment of T1a disease from 42.7% to 50.6% was accompanied by a decrease in esophagectomies from 21.7% to 12.8% (P < 0.01). For T1b disease, the rise in endoscopic treatment from 16.9% to 25.1% (P = 0.03) was accompanied by decreases in no treatment and chemoradiation, whereas the rate of esophagectomies remained approximately 50%. Unadjusted median survival was longer for patients undergoing resection: esophagectomy, 98.6 months; endoscopic therapy, 77.7 months; chemoradiation, 17.3 months; no treatment, 8.2 months; P < 0.01. Risk-adjusted Cox modeling showed esophagectomy was associated with improved survival [hazard ratio (HR): 0.85], and chemoradiation (HR: 1.79) and no treatment (HR: 3.57) with decreased survival, compared to endoscopic therapy (P < 0.01). CONCLUSIONS: Use of endoscopic therapy for T1 esophageal cancer has increased significantly: for T1a, as an alternative to esophagectomy; and for T1b, as an alternative to no treatment or chemoradiation. Despite upfront risks, long-term survival is highest for patients who can undergo esophagectomy.

BACKGROUND: We have sometimes experienced technical difficulty performing thoracoscopic esophagectomy because of the position of the descending aorta or width of the mediastinal space. In this study, we retrospectively investigated predictive preoperative factors that influence the procedure of thoracoscopic esophagectomy with a focus on the position of the descending aorta and width of the mediastinal space. METHODS: Ninety-five patients who underwent thoracoscopic esophagectomy for esophageal cancer by two specialists were included in this study. Thirty patients in whom both the operation time and blood loss in the thoracic region exceeded the median were categorized to the difficult group. The remaining 65 patients were categorized into the common group. During the evaluation of the position of the descending aorta, we measured the aorta-vertebra angle at the level of the left inferior pulmonary vein. During the evaluation of the width of the mediastinal space, we measured the sternum-vertebra distance at the level of the tracheal bifurcation. RESULTS: A forward stepwise logistic regression analysis revealed the following independent predictive factors of the technical difficulty of thoracoscopic esophagectomy: aorta-vertebra angle (≥ 30°), sternum-vertebra distance (< 100 mm), and clinical T stage (T3). CONCLUSIONS: The position of the descending aorta, width of the mediastinal space, and clinical T stage are predictive factors of the technical difficulty of thoracoscopic esophagectomy. These factors might become supporting indices for the indication for thoracoscopic esophagectomy among trainees or the surgeons who introduce this procedure.

BACKGROUND: Esophageal spindle cell carcinoma (ESpCC) is a malignant tumor composed of sarcomatous components. ESpCC is treated as a squamous cell carcinoma. However, because ESpCC is a rare tumor, little is known regarding its prognosis. This study aimed to analyze patients with ESpCC who were surgically treated at our hospital, determine the validity of surgery, and identify factors that indicate a prognosis. METHODS: Treatment characteristics, overall survival (OS), and recurrence-free survival (RFS) of 28 patients with ESpCC who underwent surgery at our hospital between 1990 and 2016 were assessed. Furthermore, factors associated with OS and RFS were analyzed. RESULTS: Subtotal esophagectomy with 3-field lymph node dissection and lower esophagectomy with 2-field lymph node dissection were performed in 25 and 3 patients, respectively. Chemotherapy was administered as preoperative therapy to two patients. Postoperative therapy, comprising radiotherapy and chemotherapy, was administered to three and nine patients, respectively. The 3- and 5-year RFS were 66.4% and 61.6% and the 3- and 5-year OS were 73% and 61.9%, respectively. Macroscopic type was identified as a prognostic factor. In terms of OS, prognosis was significantly worse in ulcerative-type ESpCC than in the polypoid type. CONCLUSION: The 5-year OS of ESpCC mainly treated with surgical therapy was 61.9%. However, prognosis was poor in some patients with ulcerative-type ESpCC according to macroscopic type. In the future, it will be necessary to accumulate more cases and investigate therapeutic strategies added to surgery to improve prognosis.

BACKGROUND: The three-dimensional video-assisted (3D-VA) system is known to provide depth perception and the precise measurement of anatomical spaces, unlike the two-dimensional video-assisted (2D-VA) system. However, the advantages of the 3D-VA system in thoracoscopic esophagectomy remains unclear. METHODS: We retrospectively analyzed data from 104 patients who underwent thoracoscopic esophagectomy for esophageal cancer from 2016 to 2017. We performed thoracic esophagectomy using either the 2D-VA or 3D-VA system during this period. Whenever the 3D-VA system was available in our surgical center, we performed 3D-VA thoracoscopic esophagectomy. Perioperative parameters, including operation times, blood loss, the number of dissected lymph nodes, postoperative complications, and the duration of postoperative hospital stays, were compared between the 2D-VA and 3D-VA system groups. RESULTS: There were 51 and 53 patients in the 2D-VA and 3D-VA system groups, respectively. Preoperative parameters, including age, sex, tumor location, clinical stage and the distribution of preoperative treatment, were not significantly different between the groups. Although intraoperative blood loss did not differ between the two groups, operation times were significantly shorter in the 3D-VA system group than the 2D-VA system group (P = 0.023). The number of dissected mediastinal lymph nodes was similar in both groups. The incidences of postoperative complications, including pneumonia, recurrent nerve palsy, anastomotic leakages and chylothorax, were similar between the groups. The duration of postoperative hospital stays was also comparable between the groups. CONCLUSIONS: An introduction of 3D-VA endoscopy into minimally invasive esophagectomies may contribute to the shortening of the duration of thoracoscopic procedures.

INTRODUCTION: Esophagectomy and lymphadenectomy are essential parts of the multimodal treatment of esophageal carcinoma with curative intent. Treatment regimens vary globally and are subject to debate. A global survey was designed to gain insight into current practice. METHODS: Fifty-seven international expert upper gastrointestinal surgeons received a personal invitation to participate in the survey, which focused on demographics and experience; extent of lymphadenectomy in adeno and squamous cell carcinoma; use of classification systems; neoadjuvant therapy; surgical approach; and specimen handling. RESULTS: The response rate was 88% (50/57 surgeons), with a mean age of 51.6 years and a median number of 15 years of experience in esophageal surgery. The variety in the extent of lymphadenectomy in proximal, middle and distal squamous cell carcinoma, and Siewert I, II and III adenocarcinoma, was considerable. The number of different combinations of lymph node (LN) stations that were resected in the same tumor was high, while the number of surgeons who removed the exact same combination of LN stations was low. Illustrative is Siewert I adenocarcinoma, in which 27 unique combinations of LN stations were resected, with a maximum of two surgeons performing the exact same dissection. Use of neoadjuvant therapy, surgical approach, and specimen handling also show great variety among participants. CONCLUSION: There is no uniform, worldwide strategy for surgical treatment of esophageal cancer. The extent of lymphadenectomy shows great variation for both histologic types. An international observational study is needed to provide evidence on the distribution pattern of lymph node metastases in esophageal cancer and the necessary extent of lymphadenectomy.

BACKGROUND: Insufficient blood supply in the gastric tube is considered as a risk factor for postoperative anastomotic strictures in patients receiving esophagectomy, but the direct evidence is lacking. AIMS: We aimed to investigate the correlation between perioperative blood supply in the anastomotic area of the gastric tube and the formation of anastomotic strictures in the patients undergoing esophagectomy. METHODS: This prospective study included 60 patients with esophageal squamous cell carcinoma undergoing Ivor Lewis esophagectomy between March 2014 and February 2016, which were divided into stricture group (n = 13) and non-stricture group (n = 47) based on their severity of anastomotic strictures at 3 months post-operation. The perioperative anastomotic blood supply was measured using a laser Doppler flowmetry. The gastric intramucosal pH (pHi) was measured by a gastric tonometer within 72 h post-operation. The perfusion index and gastric pHi were compared between groups. RESULTS: The stricture group had a significantly lower blood flow index (P < 0.001) and gastric pHi values from day 1 to day 3 post-operation than the non-stricture group (all P < 0.001). In addition, Pearson correlation analysis showed that both the perfusion index and gastric pHi were significantly correlated with stricture size and stricture scores, respectively (r = 0.65 - 0.32, all P < 0.05). Furthermore, the multivariate logistic regression analysis showed that perfusion index was an influential factor associated with postoperative anastomotic strictures (OR 0.84. 95% CI 0.72-0.98, P = 0.026). CONCLUSION: These results suggested that poor blood supply in the anastomotic area of the gastric tube in the perioperative period was a risk factor for postoperative anastomotic strictures.

The 2011 National Comprehensive Cancer Network guidelines first incorporated the results of the landmark CROSS trial, establishing induction therapy (chemotherapy ± radiation) and surgery as the treatment standard for locoregional esophageal cancer in the United States. The effect of guideline publication on socioeconomic status (SES) inequalities in cancer treatment selection remains unknown. Patients diagnosed with Stage II/III esophageal cancer between 2004 and 2013 who underwent curative treatment with definitive chemoradiation or multimodality treatment (induction and surgery) were identified from the Surveillance, Epidemiology and End Results (SEER)-Medicare registry. Clinicopathologic characteristics were compared between the two therapies. Multivariable regression analysis was used to adjust for known factors associated with treatment selection. An interaction term with respect to guideline publication and SES was included Of the 2,148 patients included, 1,478 (68.8%) received definitive chemoradiation and 670 (31.2%) induction and surgery. Guideline publication was associated with a 16.1% increase in patients receiving induction and surgery in the low SES group (21.4% preguideline publication vs. 37.5% after). In comparison, a 4.5% increase occurred during the same period in the high SES status group (31.8% vs. 36.3%). After adjusting for factors associated with treatment selection, guideline publication was associated with a 78% increase in likelihood of receiving induction and surgery among lower SES patients (odds ratio 1.78; 95% confidence interval (CI): 1.05,3.03). Following the new guideline publication, patients living in low SES areas were more likely to receive optimal treatment. Increased dissemination of guidelines may lead to increased adherence to evidence-based treatment standards.

AIM: Total gastrectomy and Ivor Lewis oesophagectomy procedures are the mainstay of upper gastrointestinal cancer management. Maintenance of adequate nutritional intake is essential for positive patient outcomes. Although numerous nutritional support options exist, clear evidence-based guidelines on the optimal means and duration of nutritional support are lacking. The aim of this study is to establish preliminary data on the current perioperative nutritional practices of upper gastrointestinal surgeons performing these procedures across Australia and New Zealand. It is hoped this will help provide the platform for future research towards establishing evidence-based guidelines in upper gastrointestinal surgery. METHODS: A questionnaire exploring the nutritional practices and considerations of surgeons was developed and emailed to the members of the Australia & New Zealand Gastric & Oesophageal Surgery Association. RESULTS: A total of 27.4% of Australia & New Zealand Gastric & Oesophageal Surgery Association members completed the questionnaire. Surgeons reported inserting a jejunostomy feeding tube intraoperatively in Ivor Lewis oesophagectomy procedures 80-100% of the time, compared to only 20-39% of the time in total gastrectomy procedures. For both procedures, surgeons often refer their patients to a dietitian preoperatively, and always postoperatively. Preoperative immune-enhancing nutrition is rarely administered. Patient age and BMI are deemed to be of low importance when determining the means of nutritional support. CONCLUSIONS: This study has demonstrated the current nutritional practices employed in Australia and New Zealand for patients undergoing major upper gastrointestinal surgery. Questions remain regarding the noted differences between procedures as well as the optimal means and duration of perioperative nutritional support.

BACKGROUND: The indication of surgical resection in esophageal cancer is often conditioned by patient's age. We aimed to assess the trends in utilization of surgical treatment for esophageal adenocarcinoma (EAC) in the United States, stratified by age groups. METHODS: We performed a retrospective analysis of the National Cancer Institute's Surveillance, Epidemiology, and End Results program registry for the period 2004-2014. Adult patients (aged ≥18 years) diagnosed with EAC were eligible for inclusion. The yearly incidence of esophagectomy, stratified by age groups (18-49, 50-70, and >70 years old), was calculated using Poisson regression. Weighted log-binomial regression was used to compare the proportion of patients undergoing esophagectomy, within each age group. Inverse probability of treatment weights were used to account for potential confounders. RESULTS: A total of 21,301 patients were included. During the study period, the rate of esophagectomy decreased from 34.1% to 28.2% (P = .40) in patients between 18 and 49 years old, from 38.6% to 33.3% (P = .06) in patients between 50 and 70 years old, and from 21.4% to 16.9% (P = .04) in patients older than 70 years. After accounting for patient and cancer characteristics, patients older than 70 years were 50% less likely to undergo esophagectomy compared with both patients between 18 and 49 years old (risk ratio [RR] 0.51, 95% confidence interval [CI] 0.45-0.57, P < .0001) and patients between 50 and 70 years old (RR 0.53, 95% CI 0.50-0.56, P < .0001). CONCLUSION: Surgical resection is scarcely used in patients older than 70 years in the United States. Further investigation of surgical outcomes in elderly patients is warranted to determine if surgical treatment is underutilized in a large proportion of EAC patients.

BACKGROUND: This study aims to define contemporary trends in characteristics, costs and management of patients diagnosed with oesophageal adenocarcinoma in New Zealand. METHODS: Clinical, pathological and management data of the 135 patients presenting with histologically proven adenocarcinoma to our institution over a 5-year period (January 2010 to December 2014) was collected. Primary analysis reviewed patient demographics, co-morbidities, treatment strategy and survival. Secondary analysis defined operative outcomes including complications, mortality rates and overall survival to December 2016. RESULTS: Thirty-eight patients underwent oesophago-gastrectomy (resection rate 28%) with curative intent following neoadjuvant chemotherapy with Clavien-Dindo ≥3 complications in 17 patients (46%). Actuarial survivals from surgery at 1, 3 and 5 years were (79, 55 and 50%), with 19 patients (54%) alive and disease free at a median follow-up of 26.5 months (range 1-82 months). Overall, this represented one sixth of the national volume of oesophagectomy. Ninety-seven patients were managed non-surgically due to metastatic or advanced local disease (n = 64), co-morbid status (n = 27), patients choice (n = 2) and unknown (n = 4). Median survival from diagnosis in non-resected patients was 9 months (range 1-40 months). CONCLUSION: Oesophagectomy remains a challenging procedure for any institution, although good results can be achieved. Foci for referral are emerging in New Zealand for the surgical management of oesophageal cancer.
