Abstract:Objective To investigate the clinical significance of laparoscopic radical resection for adenocarcinoma of esophagogastric junction (AEG) combined with minor thoracotomy anastomosis and lymph node dissection.Methods Fifty patients with cardiac cancer from June 2018 to June 2019 were selected, they were randomly divided into experimental group (n = 25) and control group (n = 25). The experimental group was treated with laparoscopic radical resection of AEG combined with minor thoracotomy anastomosis and lymph node dissection, while the control group was treated with conventional laparoscopic radical resection of AEG and lymph node dissection. The operation time, number of lymph node dissection, intraoperative blood loss, conversion rate to laparotomy, postoperative hospital stay, postoperative complications and quality of life were compared between the two groups.Results There were no significant difference in blood loss and conversion rate to laparotomy between the two groups (P > 0.05). The operation time, number of lymph node dissection, postoperative hospital stay, incidence of postoperative complications and quality of life score of the experimental group were better than those of the control group, the difference was statistically significant (P < 0.05).Conclusion The application of laparoscopic radical gastrectomy for laparoscopic radical resection of AEG combined with minor thoracotomy anastomosis and lymph node dissection can clear lymph nodes in a wider range, reduce the operation time, reduce the trauma of patients, reduce the incidence of postoperative complications, and helpful to improve the quality of life of patients after operation, which is worthy of clinical promotion.
