Abstract Purpose The robot-assisted approach for Ivor Lewis esophagectomy offers an enlarged, three-dimensional overview of the intraoperative situs. The vagal nerve (VN) can easily be detected, preserved, and intentionally resected below the separation point of the recurrent laryngeal nerve (RLN). However, postoperative vocal cord paresis can result from vagal or RLN injury during radical lymph node dissection, presenting a challenge to the operating surgeon. Methods From May to August 2019, 10 cases of robot-assisted minimally invasive esophagectomy (RAMIE) with extended 2-field lymphadenectomy, performed at the University Medical Center Mainz, were included in a prospective cohort study. Bilateral intermittent intraoperative nerve monitoring (IONM) of the RLN and VN was performed, including pre- and postoperative laryngoscopy assessment. Results Reliable mean signals of the right VN (2.57 mV/4.50 ms) and the RLN (left 1.24 mV/3.71 ms, right 0.85 mV/3.56 ms) were obtained. IONM facilitated the identification of the exact height of separation of the right RLN from the VN. There were no cases of permanent postoperative vocal paresis. Median lymph node count from the paratracheal stations was 5 lymph nodes. Conclusion IONM was feasible during RAMIE. The intraoperative identification of the RLN location contributed to the accuracy of lymph node dissection of the paratracheal lymph node stations. RLN damage and subsequent postoperative vocal cord paresis can potentially be prevented by IONM.

Abstract Description This video showed the stepwise approach for robot-assisted thoracoscopic left recurrent laryngeal nerve lymph node dissection. With the patient lying in the left semiprone position, a total of five trocars were positioned. Left RLN LND was begun by releasing the right esophagotracheal band. Subsequently, the trachea was gradually rotated clockwise through the application of a gentle pressure on the left edge of the tracheal cartilage with the goal of exposing and releasing the left esophagotracheal band. After the complete release of the bilateral esophagotracheal band, the esophagus was retracted toward the dorsal side with the right first robotic arm. Simultaneously, an assistant rolled back the trachea using a forceps grasping a small piece of gauze, with the aim of improving operative exposure. The left RLN was identified in the middle of the soft tissue between the trachea and the esophagus. Dissection was started from the ventral side RLN nodes and subsequently continued toward the dorsal side until the total skeletonization of the left RLN Disclosure All authors have declared no conflicts of interest.

Abstract Description Extended thoracoscopic lymphadenectomy is not common practice in Western countries in patients with adenocarcinoma of the esophagogastric junction. In this video we present a case of a patient with siewert I adenocarcinoma with lymph node metastasis to the right recurrent laryngeal nerve not treated with neoadjuvant therapy, due to comorbidity. The operation was: extended thoracoscopic en-block lymph node dissection. video will be edited in a more rigorous manner Disclosure All authors have declared no conflicts of interest.

Abstract   In early 2000s, cervical anastomosis after esophagectomy was associated with a higher rate of recurrent nerve trauma than thoracic anastomosis. Recently, new technologies have been developed that reduce surgical complications. Mediastinoscopic esophagectomy is reportedly less invasive and allows faster recovery than thoracoscopic esophagectomy. Intraoperative nerve monitoring (IONM) prevents recurrent laryngeal nerve (RNL) palsy. We present the case of minimally invasive mediastinoscopic Ivor-Lewis Esophagectomy (MMIE) under IONM performed on an elderly esophagogastric junction (EGJ) adenocarcinoma patient. Methods An 84-year old man was consulted for adenocarcinoma of GEJ without lymphnode metastasis. Despite his advanced age, he had no comorbidities. We planned to perform MMIE under IONM. The procedure started with a patient lithotomy, and three trocars plus small incision were made in the upper abdomen. Celiac lymphadenectomy was performed. Subsequently, a 35 mm incision was made in the left side of the neck and a monitor was attached to left vagus nerve. Three trocars were placed with single incision surgical devices and pneumomediastinum was noticed. Mediastinoscopic esophagectomy was performed. Gastric tube reconstruction via mediastinum with cervical anastomosis was performed. Results The operation was successful. Total operation time was 393 minutes, with an estimated blood loss of 5 mL. There were no intraoperative and postoperative complications, and no RLN palsy occurred. Conclusion MMIE with cervical anastomosis under IONM is safe and less invasive especially for the respiratory system as a thoracotomy is unnecessary.

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.
