Abstract
INTRODUCTION To date, the discussion is still ongoing whether the Siewert II adenocarcinoma of the esophagogastric junction (AEG) should be resected either by thoracoabdominal esophagectomy or gastrectomy with resection of the distal esophagus by transhiatal extension. The aim of our study was to compare the oncological and perioperative outcomes of the transthoracic approach (TTA) and the transabdominal approach (TAA). METHODS Searches of electronic databases identifying studies from Cochrane, PubMed and Google Scholar were performed. Randomised and non-randomised studies comparing TTA and TAA approaches for surgical treatment of AEG Siewert type II were included. The Newcastle-Ottawa and Jada scales were used to evaluate methodological quality. The risk of bias was assessed using the Rob v2 and Robins-I tools. Meta-analyses were conducted for the outcomes. RESULTS We included 17 trials (2 randomised controlled trials and 15 cohorts) involving 15297 patients. Longer three-year overall survival, five-year overall survival and R0 resection rates were observed in the TTA group. However, TTA had greater morbidity and pulmonary complications. CONCLUSION Transthoracic approach appears to be preferable for selected Siewert II tumours. This may lead to higher survival rates and better R0 resection rate. Well-designed studies are needed to confirm the results of this systematic review.

Abstract
Esophagogastric junction (EGJ) carcinoma represents a specific site of disease, given the opportunities for multimodal clinical care and management and the possibilities of combined treatments. It encompasses various clinical subgroups of disease that are heterogeneous and deserve different treatments; therefore, the guidelines have progressively evolved over time, considering the evidence provided by clinical trials. The aim of this narrative review was to summarize the main evidence, which orientates the current guidelines, and to collect the main ongoing studies to address existing gray areas.

Abstract
BackgroundSiewert type II adenocarcinoma of the esophagogastric junction (Siewert II AEG) can be resected by the right thoracoabdominal surgical approach (RTA) or abdominal-transhiatal surgical approach (TH) under minimally invasive conditions. Although both surgical methods achieve complete tumor resection, there is a debate as to whether the former method is superior to or at least noninferior to the latter in terms of surgical safety. Currently, a small number of retrospective studies have compared the two surgical approaches, with inconclusive results. As such, a prospective multicenter randomized controlled trial is necessary to validate the value of RTA (Ivor-Lewis) compared to TH.MethodsThe planned study is a prospective, multicenter, randomized clinical trial. Patients (n=212) with Siewert II AEG that could be resected by either of the above two surgical approaches will be included in this trial and randomized to the RTA group (n=106) or the TH group (n=106). The primary outcome will be 3-year disease-free survival (DFS). The secondary outcomes will include 5-year overall survival (OS), incidence of postoperative complications, postoperative mortality, local recurrence rate, number and location of removed lymph nodes, quality of life (QOL), surgical Apgar score, and duration of the operation. Follow-ups are scheduled every three months for the first 3 years after the surgery and every six months for the next 2 years.DiscussionAmong Siewert II AEG patients with resectable tumors, this is the first prospective, randomized clinical trial comparing the surgical safety of minimally invasive RTA and TH. RTA is hypothesized to provide better digestive tract reconstruction and dissection of mediastinal lymph nodes while maintaining a high quality of life and good postoperative outcome. Moreover, this trial will provide a high level of evidence for the choice of surgical procedures for Siewert II AEG.Clinical trial registrationChinese Ethics Committee of Registering Clinical Trials, identifier (ChiECRCT20210635); Clinical Trial.gov, identifier (NCT05356520).

Long-Term Survival After Transhiatal Versus Transthoracic Esophagectomy: A Population-Based Nationwide Study in Finland. Ann Surg Oncol 2022; 29:8158-8167.

Abstract
BACKGROUND No population-based studies comparing long-term survival after transhiatal esophagectomy (THE) and transthoracic esophagectomy (TTE) exist. This study aimed to compare the 5-year survival of esophageal cancer patients undergoing THE or TTE in a population-based nationwide setting. METHODS This study included all curatively intended THE and TTE for esophageal cancer in Finland during 1987-2016, with follow-up evaluation until 31 December 2019. Cox proportional hazard models provided hazard ratios (HRs) with 95% confidence intervals (CIs) of 5-year and 90-day mortality. The results were adjusted for age, sex, year of operation, comorbidities, histology, neoadjuvant treatment, and pathologic stage. RESULTS A total of 1338 patients underwent THE (n = 323) or TTE (n = 1015). The observed 5-year survival rate was 39.3% after THE and 45.0% after TTE (p = 0.072). In adjusted model 1, THE was not associated with greater 5-year mortality (HR 0.99; 95% CI 0.82-1.20) than TTE. In adjusted model 2, including T stage instead of pathologic stage, the 5-year mortality hazard rates after THE (HR 0.87, 95% CI 0.72-1.05) and TTE were comparable. The 90-day mortality rate for THE was higher than for TTE (adjusted HR 0.72; 95% CI 0.45-1.14). In subgroup analyses, no differences between THE and TTE were observed in Siewert II gastroesophageal junction cancers, esophageal cancers, or pN0 tumors, nor in the comparison of THE and TTE with two-field lymphadenectomy. The sensitivity analysis, including patients with missing patient records, who underwent surgery during 1996-2016 mirrored the main analysis. CONCLUSIONS This Finnish population-based nationwide study suggests no difference in 5-year or 90-day mortality after THE and TTE for esophageal cancer.

Abstract
Background The optimal surgical approach, whether transabdominal (TA) or transthoracic (TT), for Siewert type II adenocarcinoma of the esophagogastric junction (AEG) remains controversial. This study compares the efficacy of TA and TT surgical approaches for Siewert type II AEG. Methods Studies comparing the surgical and oncological outcomes of TA and TT surgical approaches for Siewert type II AEG up to June 2021 were systematically searched on the Web of Science, PubMed, Embase, and Cochrane Library. A pooled analysis was performed for the available data regarding the baseline features, surgical, and oncological outcomes. The RevMan 5.3 software was used to perform the statistical analysis. Quality evaluation and publication bias were also conducted. Results Twelve studies with a total of 2,011 patients, including 985 patients in the TA group and 1,026 patients in the TT group, were included in this study. In the pooled analysis, the surgical outcomes, namely, operative time (MD = −54.61, 95% CI = −123.76 to 14.54, P = 0.12), intraoperative blood loss (MD = −28.85, 95% CI = −71.15 to 13.46, P = 0.18), the number of dissected lymph nodes (MD = 1.90, 95% CI = −1.32 to 5.12, P = 0.25), postoperative complications (OR = 0.84, 95% CI = 0.65 to 1.07, p = 0.16), anastomotic leakage rate (OR = 1.02, 95% CI = 0.63 to 1.65, p = 0.93), and postoperative death rate (OR = 0.89, 95% CI = 0.46 to 1.72, p = 0.73), and the oncological outcomes, namely, overall recurrence rate (OR = 0.75, 95% CI = 0.37 to 1.50, p = 0.41), 3-year overall survival (OS) rate (OR = 1.19, 95% CI = 0.54 to 2.65, p = 0.66), and 5-year OS rate (OR = 1.21, 95% CI = 0.84 to 1.74, p = 0.30) of the two groups were all comparable. Conclusions Both TA and TT surgical approaches are appropriate for Siewert type II AEG, and neither has a significant advantage in terms of short- and long-term outcomes. However, more high-quality randomized controlled trials are needed to confirm this conclusion.

Abstract
Background Few studies have evaluated the outcomes of transhiatal and right thoracoabdominal resection of Siewert type II adenocarcinoma of the esophagogastric junction. This study investigated the relative effect of these two methods in the surgical treatment of Siewert type II adenocarcinoma of the esophagogastric junction. Methods Clinical data for 211 Siewert type II cancer patients were collected and classified into transhiatal group (n = 181) and right thoracoabdominal group (n = 30) according to surgical approach. Short-term outcomes were compared between these two groups. A 1:1 propensity score matching was performed using a logistic regression model. Recurrence-free survival and overall survival were compared between the matched groups. Results The right thoracoabdominal group had significantly greater intraoperative blood loss and longer operative time compared with transhiatal group. Complications corresponding to Clavien–Dindo grade III or higher were 4.4% in transhiatal group and 30% in right thoracoabdominal group (P < 0.05). The right thoracoabdominal group exhibited greater blood loss, longer operative time, longer hospitalization, and a smaller number of lymph nodes retrieved than the transhiatal group as evidenced by PSM analysis, and patients in transhiatal group also experienced significantly better survival than patients in right thoracoabdominal group. Conclusion In this study, the transhiatal approach was associated with more favorable short-term and oncological outcomes than the right thoracoabdominal group approach for Siewert type II adenocarcinoma of the esophagogastric junction. The transhiatal approach with total gastrectomy appears to be an optional choice for this type of tumor, especially for esophagus invasion ≤2 cm. Well-designed randomized control trials are necessary to validate our findings.
