Abstract Background We previously reported the performance of mediastinoscopic esophagectomy with lymph node dissection (MELD) under pneumomediastinum using a transcervical and transhiatal approach as a method of radical esophagectomy. For more complete lymph node dissection, it is necessary to dissect via not only left cervical but also right cervical approach in pneumomediastinum. We herein report the dissection method for upper mediastinum using a cervico-pneumomediastinal approach including right cervical approach in pneumomediastinum and the short surgical outcome. Methods This method was applied to nine cases for esophageal cancer. The right recurrent nerve was first identified using an open approach. Pneumomediastinum was then initiated to allow for the 105 and 106recR lymph nodes to be completely dissected along the right mediastinal pleura, the right vagus nerve, the proximal portion of the azygos vein and the right bronchial artery. The left recurrent nerve (106recL) lymph nodes and 106tbL lymph nodes were dissected using a cross-over technique, as described previously. Results This operation using bilateral cervical approach in pneumomediastinum were performed for nine cases. The median operation time and bleeding is 606 minutes and 506 ml, respectively. The median post-operative stay is 15 days. Conclusion MELD is therefore considered to be a more minimally invasive and useful modality for radical esophagectomy than the thoracic approach, although the field of view is different from that of the thoracic approach.

We previously reported the performance of “mediastinoscopic esophagectomy with lymph node dissection” (MELD) under pneumomediastinum using a transcervical and transhiatal approach, as a method of radical esophagectomy. The procedure included the dissection of the left tracheobronchial lymph nodes (106tbL). We described our technique for dissecting the upper mediastinal lymph nodes. We revealed that the 106tbL lymph nodes were almost completely retrieved but that the upper thoracic paraesophageal lymph nodes (105) and the right recurrent nerve lymph nodes (106recR) were not completely retrieved. We are therefore of the opinion that a right cervical pneumomediastinal approach is necessary to achieve total dissection. We herein describe a case that was surgically treated using a bilateral cervicopneumomediastinal approach. A 68-year-old male patient was referred to our institution to undergo treatment for lower thoracic esophageal squamous cell carcinoma. The right recurrent nerve was first identified using an open approach. Pneumomediastinum was then initiated to allow for the 105 and 106recR lymph nodes to be completely dissected along the right mediastinal pleura, the right vagus nerve, the proximal portion of the azygos vein, and the right bronchial artery. The left recurrent nerve lymph nodes (106recL) and 106tbL lymph nodes were dissected as described previously. In order to perform bilateral upper mediastinal lymph node dissection and esophagectomy, a bilateral cervicopneumomediastinal approach is needed.

Abstract Background The aim of the present study was to evaluate subcarinal lymph node dissection in transmediastinal radical esophagectomy and subcarinal lymph node metastasis in patients with esophageal cancer. Methods Three hundred and twenty-three patients with primary esophageal cancer who underwent transmediastinal or transthoracic esophagectomy with radical two- or three-field lymph node dissection were retrospectively investigated. The clinicopathological characteristics of patients with subcarinal lymph node metastasis were analyzed in detail. Results The median of dissected subcarinal lymph nodes in transmediastinal and transthoracic esophagectomy groups was 6 and 7, respectively, and there was no significant difference between the two groups (p = 0.12). Of all patients, 26 (8.0%) were pathologically diagnosed as positive for subcarinal lymph node metastasis, whereas only 7 (26.9%) of those with metastasis were preoperatively diagnosed as positive. In addition, all patients with subcarinal lymph node metastasis had other non-subcarinal lymph node metastasis. By univariate analysis, subcarinal lymph node metastasis was found in larger (≥ 30 mm) and deeper (T3/T4a) primary lesions (p = 0.02 and 0.02, respectively), but it was not found in 49 patients with the primary lesion located in the upper thoracic esophagus. Conclusions Subcarinal lymph nodes can be dissected in transmediastinal esophagectomy, almost equivalent to transthoracic esophagectomy. The tumor size, depth, and location may be predictive factors for subcarinal lymph node metastasis.

Abstract Aim Lymphadenectomy in minimally-invasive esophageal cancer surgery still remains challenging and standardization of surgical procedures is of extreme importance. The aim of this study is to present our safe and reproducible technique in thoracoscopic superior lymphadenectomy during esophagectomy for cancer. Background & Methods In esophageal cancer surgery, dissection of the superior mediastinal lymph-nodes is of high importance. For adequate mediastinal lymph-node dissection, an extensive operating field is required along with appropriate equipment and experience. Thoracoscopy in prone position provides excellent visualization of the operative field comparing to thoracotomic phase. A step-by-step explanation of our surgical technique during thoracoscopic superior lymphadenectomy is provided. Results All patients were placed in prone position. The entire posterior mediastinal pleura was incised; azygos arch was divided with clips, facilitating dissection of the left side of the posterior mediastinum. The descending thoracic aorta was freed anteriorly, separating the esophagus; the thoracic duct was dissected and divided with vascular clips. Esophageal hiatus was dissected circumferentially and the esophageal wall was freed from the pericardiumanteriorly. Subcarinal lymph-nodes were dissected en bloc. Upper thoracic esophagus was separated from the membranous part of the trachea. The right recurrent laryngeal nerve lymph nodes were dissected at the level of the right subclavian artery, with extreme caution to avoid nerveinjury. Left recurrent laryngeal nerve was identified by posterior traction of the esophagus using a full thickness transluminal suture;by pulling it through a separate skin incision, the relative lymph nodes were dissected. Conclusion It is interesting that, higher number of lymph-nodes are harvested with this procedure which may be the result of better visualization/access. Overall, our technique has been standardized, is safe and reproducible and could be adopted by specialized Upper GI Units.

Objective: We reviewed the surgical outcomes of minimally invasive esophagectomy (MIE), especially the number of lymph nodes retrieved, for the patients with esophageal cancer to clarify the surgical benefits of MIE in patients with esophageal cancer. Material and Methods: A systematic literature search was performed, and articles that fully described the surgical results of MIE were selected. Parameters such as operative time, blood loss, the number of lymph nodes retrieved, and postoperative complications were compared among patients undergoing minimally invasive esophagectomy (MIE) in the left lateral decubitus position (MIE-LP), MIE in the prone position (MIE-PP), and open thoracic esophagectomy (OE). Results: The conversion rate from MIE to OE was very low. MIE-PP was associated with lower blood loss than OE and MIE-LP. Results of a multicenter randomized controlled trial demonstrated that pneumonia and recurrent laryngeal nerve paralysis in MIE-PP significantly reduced compared with OE. Although postoperative complications were not different between MIE-PP and MIE-LP, the number of lymph nodes retrieved in MIE-PP was higher than that in MIE-LP. Conclusion: MIE-PP has potential benefits in terms of less surgical invasiveness and improvement of mediastinal lymph node dissection. A prospective randomized control trial using a large number of cases and long-term follow-up is recommended for analyses of appropriate mediastinal lymph node dissection and its impact on oncological benefit.

Abstract Background Due to the difficulty of dissection, surgical trauma, postoperative complications and other factors, the promotion of 3-field lymph node dissection is subject to certain restrictions. We try to explore and summarize a method of lymph node dissection, ‘endoscopic 2.5 lymph node dissection ’, that is, thoracoscopy combined with laparoscopic radical abdominal field, chest field and lower cervical paraesophageal lymph nodes (including 101 group below thyroid artery). Methods Retrospective analysis of 240 patients with thoracic esophageal squamous cell carcinoma from November 1, 2015 to December 31, 2017. All patients underwent endoscopic 2.5-field lymphadenectomy. The average age is (58.2 ± 9.5) years old. During the thoracoscopic part, when we do the lymphadenectomy along recurrent laryngeal nerves in the upper mediastimun and lower neck, we used a combination of ‘esophageal suspension method’, ‘lymph node rolling dissection method’ and ‘multi-angle pulling method’ to reveal the lymph nodes (Figure 1). Surgical related factors were collected and analyzed. Continuous follow-up was performed to record the recurrence and metastasis of patients and postoperative survival. Results Lymphadenectomy level of the right recurrent laryngeal nerve could reach the level above the right inferior thyroid artery, and the left could reach the level of 101 station. All operations were successfully completed. The incidence of pulmonary infection was 11.7%, the incidence of anastomotic leakage was 1.3%, the hoarseness rate was 7.9% and the incidence of chylothorax was 4.2%. The average number of total, abdominal and thoracic lymph nodes dissected were higher than the number of guidelines requirement and most of the previous literature. The average postoperative hospital stay was 8.4 days. The local recurrence rate, metastasis rate and survival rate of all the patients were not inferior to those reported in the past. Conclusion In patients with thoracic esophageal squamous cell carcinoma, the use of ‘total endoscopic 2.5-field lymph noede dissection’, could expand the range of lymph node dissection, and reached the super-thoracic and lower cervical level, which is beneficial to improve the degree of dissection along the recurrent laryngeal nerves. The procedure is safe and feasible, the results of short-term follow-up results are good, and it is worth further promotion. Disclosure All authors have declared no conflicts of interest.

Abstract Aim To evaluate the involvement of subcarinal lymph node dissection (SLND) in the surgical treatment of esophageal cancer, as well as its impact on surgical outcomes following esophagectomy. Background & Methods Data on patients that underwent esophagectomy from 01/03/2014 to 01/03/2019 were prospectively collected and retrospectively reviewed. Based on the medical records, the following parameters were collected and analyzed: patient demographics, histopathological parameters, surgical- oncological outcomes. All patients were staged according to the AJCC 8th edition. Results A total of 79 patients underwent Ivor Lewis or McKeown esophagectomy for either squamous cell carcinoma (n= 7 patients) or adenocarcinoma of the esophagus or gastroesophageal junction (n= 72 patients). In 26 cases, esophagectomy was performed without SLND, while 53 cases underwent SLND. Among the 53 patients, 50 (94.3%) were men, and 3 (5.7 %) were women. Mean age was 61.4 years, (range 34-78). Mean nodal harvest was 34.7 lymph nodes per patient. Lymph node invasion was noted in 33 patients (62.2%), with a mean of 9 positive lymph nodes per patient. Subcarinal lymph nodes were involved in 5 out of 53 patients (9.4%). The ratio of positive subcarinal lymph nodes to resected ones was 1/2 (50%), 3/3 (100%), 1/2 (50%), 1/2 (50%) and 1/1 (100%) for each patient. Final histopathological report showed adenocarcinoma of moderate or poor differentiation (G2 2/5, G3 3/5) in all five patients (100%). Four out of 5 patients had not received neoadjuvant treatment and their pathological staging was T3N3M0. One patient had received neoadjuvant chemotherapy and his final staging was ypT3N2M0. Noteworthy, the seven patients diagnosed with squamous carcinoma, were subjected to SLND and were 100% negative for invasion histologically. Conclusion Subcarinal lymph nodes were infiltrated in 9.4% of patients operated for esophageal cancer. In the squamous cell cancer group, the relative infiltration rate was notably 0%. It seems that omission of subcarinal lymph node dissection during transthoracic esophagectomy cannot be justified.

Abstract   Several authors have reported on the left trans-cervical and transhiatal approaches under pneumomediastinum and right cervical open surgery for mediastinoscopic esophagectomy. However, with these approaches, sufficient dissection of the right upper mediastinal paraesophageal lymph nodes, right recurrent nerve lymph nodes and the subaortic arch to the left tracheobronchial lymph nodes is thought to be difficult. We herein report the usefulness of the ‘bilateral’ trans-cervical pneumomediastinal approach. Methods Ten patients with thoracic esophageal cancer were treated using this approach. Under pneumomediastinum via a right neck incision, the right cervical and upper mediastinal paraesophageal lymph nodes were dissected. The left recurrent nerve lymph nodes were dissected using a left trans-cervical pneumomediastinal approach. The subaortic arch to the left tracheobronchial lymph nodes was dissected with a combined right and left trans-cervical crossover approach. After this approach, thoracoscopic observation was then performed in the left decubitus position, and if the lymph nodes were not sufficiently dissected, the remnant lymph nodes were retrieved thoracoscopically. Results The average total number of dissected lymph nodes among the right cervical and upper mediastinal paraesophageal lymph nodes identified with a right cervical open/right trans-cervical mediastinoscopic/right thoracoscopic approach was 3.2/4.0/0.6, respectively. The average total number of dissected lymph nodes among the subaortic arch to the left tracheobronchial lymph nodes with a right trans-cervical mediastinoscopic/right thoracoscopic approach was 1.5/0.6, respectively. These findings indicate that, without the right trans-cervical pneumomediastinal approach, roughly four of the right cervical and upper mediastinal paraesophageal lymph nodes and one or two of the subaortic arch to the left tracheobronchial lymph nodes could not have been retrieved. Conclusion A bilateral trans-cervical pneumomediastinal approach is useful for achieving sufficient upper mediastinal lymph node dissection and esophagectomy.

101 Background: Though postoperative radiation for esophageal cancer is offered in selected cases, there is conflicting evidence as to whether it improves overall survival (OS). We performed a retrospective investigation to analyze the prognosis impact of adjuvant radiation in a large cohort of patients. Methods: From 2002 to 2008, 545 patients underwent radical esophagectomy (R0) with or without postoperative radiation were eligible for retrospectively analysis. Patients were grouped to surgery only (n=346) and surgery plus postoperative radiation therapy (PORT) (n=199). Radiation dose was 50 Gy in 25 fractions. Kaplan-Meier and Cox regression analysis were used to compare OS. Results: The use of PORT was associated with significantly improved OS ( p =0.006). The median OS was 31 months in the group receiving PORT and 21 months in the group undergoing surgery alone. The addition of PORT improved OS at 3 years from 38.3 to 45.8% compared with surgery alone. For American Joint Committee on Cancer (AJCC) stage III esophageal cancer (T1-2N2M0, T3N1-2M0, T4N1-3M0), there was significant improvement on OS ( p < 0.001) in PORT group, for not only metastatic lymph-node ratio <0.25 ( p = 0.047), but also metastatic lymph-node ratio >0.25 ( p = 0.013). However, for stages IIB disease (T1-2N1M0) there was no significant differences. Conclusions: This large population-based analysis supports the use of PORT for pathologic lymph nodes positive stage III esophageal cancer. Our results suggest that a subset of such patients may benefit from aggressive local therapy.
