477 MINIMALLY INVASIVE MEDIASTINOSCOPIC IVOR-LEWIS ESOPHAGECTOMY WITH CERVICAL ANASTOMOSIS FOR ESOPHAGOGASTRIC JUNCTION ADENOCARCINOMA PATIENT UNDER INTRAOPERATIVE RECURRENT LARYNGEAL NERVE MONITORING

Abstract

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.
