Background: In patients with locally advanced esophageal cancer who had undergone chemoradiotherapy (CRT), the limitations of radiological evaluation may necessitate surgical exploration to ascertain disease resectability. Upon intraoperative confirmation of T4b disease (sT4b), the optimal management strategy remains unclear. While some surgeons may opt against resection, others advocate for palliative esophagectomy (PE). Regrettably, the current literature does not provide a consensus on the most effective approach for managing these intricate cases. Methods: The study cohort consisted of 68 patients with esophageal squamous cell carcinoma (ESCC) who presented with sT4b disease following CRT. The perioperative outcomes and overall survival (OS) were compared between patients who underwent PE (n = 56) and those who received an open-close (OC) procedure (n = 12). Results: Patients who underwent an OC procedure experienced a shorter hospital stay (16.5 vs. 28.8 days; p = 0.052) and showed a non-significant reduction in the rate of major complications (33.9% vs. 25%; p = 0.549) and in-hospital mortality (0% vs. 5.4%; p = 0.412) than those who received PE; however, PE was associated with a superior 2-year OS rate than OC (9.6% vs. 0%; p = 0.009). In multivariable analysis, a pretreatment clinical stage of II/III (hazard ratio [HR] 0.51, 95% confidence interval [CI] 0.31−0.87; p = 0.013) and PE with retrosternal reconstruction (HR 0.38, 95% CI 0.15−0.49; p = 0.010) were independently associated with a more favorable OS. Conclusion: PE with retrosternal reconstruction may be a feasible approach for patients with ESCC exhibiting sT4b disease after CRT. [ABSTRACT FROM AUTHOR]

Abstract Background Upper extremity deep vein thrombosis (UEDVT) is relatively rare but cannot be negligible because it can cause fatal complications. Although it is reported that the occurrence rate of UEDVT has increased due to central venous catheter (CVC), cancer, and surgical invasion, there is still limited information for esophagectomy. The aim of this study was to evaluate the clinical factors, including CVC placement and thromboprophylaxis approach, as well as retrosternal space’s width as a predictive factor for UEDVT in patients receiving esophagectomy. Methods This study included 66 patients who underwent esophagectomy with retrosternal reconstruction using a gastric tube. All patients routinely underwent contrast-enhanced computed tomography (CT) on the 4th postoperative day. Low-molecular-weight-heparin (LMWH) was routinely administered by the 2nd postoperative day. To evaluate retrosternal space’s width, (a) The distance from sternum to brachiocephalic artery and (b) the distance from sternum to vertebra were measured by preoperative CT, and the ratio of (a) to (b) was defined as the width of retrosternal space. Results Among all patients, 11 (16.7%) suffered from UEDVT, and none was preoperatively received CVC placement, while 7 were inserted in non-UEDVT cases. Retrosternal space’s width in patients with UEDVT was significantly smaller than that in patients without UEDVT (0.17 vs. 0.26; P

Abstract A median sternotomy is often performed in patients with gastric tube cancer reconstructed through the retrosternal route; however, this procedure is invasive and has the risk of severe infectious complications. To overcome these problems, we created a novel method to perform the reconstructed gastric tube resection using a gastric tube inversion technique combined with a laparoscopic mediastinal approach. After the duodenum was divided, the oral side of the cut end was sutured with silken threads for traction. The gastric tube was dissected from the caudal side under a laparoscopic mediastinal approach, whereas the cervical esophagus was taped. After the adhesion between the middle side of the posterior sternum and the reconstructed gastric tube was dissected to the cervix, the gastric tube was inverted by guiding and pulling the thread toward the cervical side. Sharp dissection was facilitated between the inverted gastric tube and the surrounding organs under moderate traction and a favorable surgical view. We have performed this procedure and evaluated the short‐term outcomes in six cases. The laparoscopic mediastinal approach was completed without a median sternotomy in all six cases. Restorable intraoperative lung injury was observed in one case and no major vessel injuries were observed. The postoperative course was satisfactory with a 29.5‐day median length of hospital stay (range, 16‐60 days). The gastric tube inversion technique combined with the laparoscopic mediastinal approach for patients with retrosternal‐reconstructed gastric tube cancer was shown to be safe and less invasive and should be considered in resection of the reconstructed gastric tube.

OBJECTIVES The retrosternal route has been an alternative for oesophageal reconstruction after oesophagectomy. But the longer route and the higher incidence for cervical anastomotic leakage compared with the posterior mediastinal approach have always hampered its wider use. However, with the recent work reported by Chen and colleagues, the anterior route has been confirmed to provide the shortest physiological distance for oesophageal reconstruction using the stomach. Furthermore, improving the original surgical procedures seemed to improve outcomes. This research aims to evaluate whether modification of the original surgical standard of alimentary tract reconstruction after oesophagectomy can reduce the incidence of anastomotic leakage. METHODS One hundred and two patients were divided into the research group and the control group. Subjects in the research group received the improved three-incision oesophagectomy (right chest/belly/left neck) after which the alimentary tract reconstruction was achieved by using a gastric conduit positioned through the retrosternal route. Patients in the control group received the original surgical procedures. Parameters such as the incidence of anastomotic leakage, pneumonia, length of hospital stay, ICU stay and pathological staging were compared between the two groups. RESULTS No significant statistical differences were found in parameters such as age, gender, height, weight, comorbidities, location and length of the tumour and final pathological staging of the patients between the two groups. Similarly, intraoperative and postoperative information such as operating time, hospital stay, pneumonia and volume of blood loss are comparable between the two groups. The incidence of anastomotic leakage was, respectively, 4.84% (3/62) in the research group and 20% (8/40) in the control group. The incidence of anastomotic leakage in the research group was lower than the one in the control group, and the difference was statistically significant (P = 0.037). CONCLUSIONS Modifications of the original surgical standard including expanding the retrosternal tunnel, widening the gastric tube, resection of the sternothyroid muscle and fixation of the gastric tube, contribute to decreasing the incidence of cervical anastomotic leakage.

Anastomotic stenosis after esophagectomy is a major cause of long-term morbidity because it leads to poor dietary intake and malnutrition that markedly reduces the quality of life. The aim of this study was to test the hypothesis that anastomosis behind the sternoclavicular (SC) joint in retrosternal reconstruction is associated with an increased risk of anastomotic stenosis compared with anastomosis deviated from the joint. Among 226 patients who underwent esophagectomy for esophageal cancer between April 2010 and March 2019, we selected 114 patients who underwent retrosternal reconstruction using a gastric conduit for this study. They were classified into two groups according to the location of the anastomosis as determined by axial sections on postoperative computed tomography scans: anastomosis located behind the SC joint (Group B; n = 71) and anastomosis deviated from the joint (Group D; n = 43). The primary endpoint was the difference in the incidence of anastomotic stenosis between the two groups. Whether the occurrence of anastomotic leak affected the likelihood of anastomotic stenosis was also investigated. The incidence of anastomotic stenosis was significantly higher in Group B than in Group D (71.8% [n = 51] vs. 18.6% [n = 8]; P < 0.0001). The incidence of stenosis in patients who developed an anastomotic leak was significantly higher in Group B than in Group D (88.0% vs. 41.7%; P = 0.0057), although the findings were similar in patients who did not develop anastomotic leak (63.0% and 9.7%, respectively; P < 0.0001). We conclude that anastomosis located behind the SC joint in retrosternal reconstruction with a gastric conduit after esophagectomy is associated with an increased risk of anastomotic stenosis regardless of the development of anastomotic leak., (© The Author(s) 2020.

Modern esophagectomy includes the esophageal extirpation with immediate reconstruction of the gastrointestinal (GI) continuity via posterior mediastinal route. In the majority of cases tubularized stomach is chosen as the conduit of choice. Other conduits, such as colon or small bowel can be used for these purposes as well. In rare circumstances use of the alternative route for the conduit placement is required.
