Summary
The incidence of esophagogastric junction has been increasing in recent years, and surgery is an important method for the treatment of adenoma at the esophagogastric junction. Currently, there is a great controversy about the surgical method of Siewert II, mainly choosing the right chest or the left chest for thoracic surgery. Therefore, it is of great significance to further study the surgical methods of Siewert II esophagogastric junction adenoma. Objective: To compare the safety, feasibility, and clinical efficacy of endoscopic Ivor-Lewis versus laparoscopic extended abdominal gastrectomy for Siewert type Ⅱadenocarcinoma at the resectable esophagogastric junction.
Description
At present, the main surgical approaches for the treatment of esophagogastric junction adenocarcinoma include single left thoracic incision, 2 right epigastric incisions, 2 left epigastric incisions, 3 cervicothoracoabdominal incisions, and left thoracoabdominal combined incision and esophageal rift through the diaphragm. Siewert type I ESOPHAgogastric junction carcinoma recommends a right thoracic approach, including Ivor-LEIws and McKeown, according to the Chinese Expert consensus for surgical treatment of ESOPHAgogastric junction adenocarcinoma published in 2018. Siwert TYPE III adenoma at esophagogastric junction, esophageal hiatus through diaphragmatic approach is recommended. The surgical approach for siwert type II adenoma at the esophagogastric junction is controversial [7,8]. Due to the particularity of siWERT type II lymph node diffusion, it can spread to both posterior mediastinal lymph nodes and abdominal lymph nodes, and a simple esophageal hiatus through the diaphragm may not be enough to clear lymph nodes. Does a combined thoracoabdominal approach improve patient outcomes? In the 1990s and early 2000s, the Japanese Clinical Oncology Organization (JCOG) compared the efficacy of different surgical approaches for esophagogastric junction adenocarcinoma. The trial randomized patients to transesophageal hiatus or left thoracoabdominal combined approach. Results The incidence of postoperative pneumonia was significantly higher in the left thoracoabdominal approach group than in the transesophageal hiatus group (13%vs. 4%, P=0.048), there was no significant difference in the survival rate of Siewert II type ESOPHAgogastric junction tumor between the two groups (P=0.496). To provide the best, targeted treatment for patients with esophagogastric junction adenocarcinoma, radical resection of the tumor should be combined with resection of adjacent lymph nodes. Previous studies have shown that the effect of surgery on the right chest is better than that on the left. Therefore, we asked whether the endoscopic Ivor-Lewis approach was better than the laparoscopic transabdominal enlarged gastrectomy. The right thoracic approach is the recommended approach for siwert type I adenoma at the esophagogastric junction. It has obvious advantages in postoperative esophageal and cardiopulmonary function protection. Currently, there are no clinical trials of endoscopic Ivor-Lewis and laparoscopic extended abdominal gastrectomy for the treatment of siwert type II adenoma at the esophagogastric junction. Endoscopic IVOR-Lewis and laparoscopic transesophageal hiatus test provide new clinical data for the treatment of siwert TYPE II adenoma at the esophagogastric junction, and help standardize the treatment of siwert type II adenoma at the esophagogastric junction. Therefore, based on our experience and foundation of gastrointestinal surgery in the treatment of esophagogastric junction tumors, through practical observation and research on clinical experimental treatment plans, and integration of domestic superior resources, the establishment and improvement of treatment standards for esophagogastric junction adenoma will be further promoted.
