Abstract   There is no consensus on the mediastinal lymph node dissection range for esophagogastric junction cancer (EGJC). Methods We enrolled 113 patients with EGJC (defined by Nishi’s classification) who underwent R0 resection between January 2001 and December 2016, focusing on comparisons between squamous cell carcinoma (SCC) and adenocarcinoma (AC). Results The characteristics of patients with SCC (n = 53) and AC (n = 55) were as follows: age: 65.4 ± 1.4 and 64.1 ± 1.5 years; male/female: 46/12 and 48/7; preoperative treatment (none/NAC/NACRT): 29/19/10 and 53/2/0; surgical method (subtotal esophagectomy/lower esophagectomy and gastrectomy): 39/19 and 34/21; pStage (I/II/III): 15/14/29 and 13/10/32, respectively. Esophageal invasion (EI) exceeding 20 mm was associated with an increased incidence of metastasis to the upper and middle mediastinal LN in patients with SCC and AC. However, for patients with SCC, the upper/middle mediastinal LN dissection effect index was 6.9/6.9 compared with 0/0 for AC patients. Conclusion In patients with EI exceeding 20 mm, esophagectomy with lymphadenectomy up to the upper mediastinum should be performed owing to the high incidence of upper and middle mediastinal LNM. However, the dissection effect is very poor in patients with AC; therefore, multidisciplinary treatment should be considered for these patients.

Abstract Background Esophagogastric junction cancer has been increasing recently. As a result, opportunities to perform transhiatal lower mediastinal lymphadenectomy are also increasing. Laparoscopic surgery is useful because the operating field of this site is too deep and narrow to perform laparotomy. But the anatomy of this area is not sufficiently clarified, and since there are few structures as landmarks, it is difficult to set the range and depth of lymph node dissection. Methods We have been verifying anatomically and embryologically the infracardiac bursa (ICB) identified as a closed lumen between the esophagus and the right crus of the diaphragm during an operation. We standardized the procedure of transhiatal lower mediastinal lymphadenectomy setting several landmarks including ICB. Results In transhiatal lower mediastinal lymphadenectomy, it is possible to do a precise lymphadenectomy by setting several landmarks including the ICB and standardizing each procedure on the ventral side, dorsal side, and both sides of the esophagus. In the case of advanced cancer which invades organs around the hiatus, it is difficult to perform routine dissection by using the infracardiac bursa or the dissectable layer. Understanding of the anatomy of this area will support the safe and precise lymphadenectomy. Conclusion In this presentation, we will show the procedure of transhiatal lower mediastinal lymphadenectomy using the ICB as a landmark.
