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 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.

Objective This study investigated the use of a new bipolar sealing device (BSD) in right superior mediastinal lymph node dissection during thoracoscopic surgery. Methods The study population consisted of 42 consecutive patients undergoing lobectomy with right superior mediastinal lymph node dissection for primary lung cancer. Operative results were compared with those of conventional surgery in 42 background-matched controls. The primary endpoint for the present analysis was the success of right superior mediastinal lymph node dissection during thoracoscopic surgery using a BSD. The secondary endpoints included the duration of the operation, number of dissected lymph nodes, chest drainage volume and duration, postoperative hospital stay, morbidity, and mortality. Results The BSD was used successfully in 42 patients. No significant difference in duration of lymph node dissection, chest drainage volume, drainage duration, or number of dissected lymph nodes was observed between the study group and the controls. Because of a learning curve, the procedure initially took more than 20 minutes to complete, but surgical time was reduced to approximately 15 minutes after the procedure was performed in 15 patients. Conclusions Our method is safe and in no way inferior to the conventional procedure. The tendency of the learning curve suggests that a significantly shorter duration of lymph node dissection is possible using this method.

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 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 Background The development of minimally invasive surgery has yielded many benefits, therefore the number of patients undergoing thoracoscopic radical esophagectomy (TRE) for esophageal cancer has been increasing worldwide. However, in the Japanese nationwide web-based database report, the incidence of recurrent laryngeal nerve (RLN) paralysis and overall morbidity were significantly higher in the TRE group than in the open esophagectomy group. In recent years, intraoperative nerve monitoring (IONM) is commonly being used in thyroid and parathyroid surgery in many centers. We tried to determine the feasibility and effectiveness of IONM of RLN during upper mediastinal lymph node dissection in TRE. Methods All 628 patients who underwent TRE in the left lateral decubitus position at Osaka City University Hospital between May 1995 and February 2018 were enrolled in the present study. We introduced IONM using NIM® (Medtronic) during TRE from October 2016 at our hospital. We divided retrospectively the patients into two groups: IONM group (TRE with IONM of RLN; n = 49) and No-IONM group (TRE without IONM of RLN; n = 579). Diagnosis of RLN paralysis was performed using laryngoscopy. The feasibility of IONM during TRE and the incidence of postoperative RLN paralysis were compared with those in No-IONM group. Results IONM could be performed for 46 patients (93.9%) in IONM group. Three patients (6.1%) could not keep single-lung ventilation using a single lumen tracheal tube with a bronchial blocker and needed to replace a tracheal tube by a double lumen tube during TRE. The incidence of postoperative RLN paralysis (CD≧ 1; CD; Clavien-Dindo classification of surgical complications) was 17.4% in IONM group and 30.2% in No- IONM group. There was a significant difference in the incidence of postoperative RLN paralysis (P < 0.05). Moreover, the right and bilateral paralysis of RLN after TRE did not occur in any patients in IONM group. Conclusion IONM of RLN during TRE is technically feasible. The introduction of standardized IONM of RLN during TRE is able to reduce the incidence of postoperative RLN paralysis. Disclosure All authors have declared no conflicts of interest.

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.
