Effect of severed right gastric artery on postoperative anastomosis after Mckeown surgery for esophageal carcinoma: A Randomized controlled trial

Objective To evaluate the effect of right gastric artery on anastomotic fistula and anastomotic stenosis after Mckeown surgery for esophageal carcinoma. Methods Prospective analysis of 120 esophageal cancer resection from July 2018 to July 2020 In all cases, esophagogastric and neck anastomosis was performed and randomly divided into 60 cases in the right gastric artery sparing group (Group A) and 60 cases in the right gastric artery disconnection group (Group B), and the occurrence of anastomotic fistula and stenosis in different surgical groups were analyzed. Results Postoperative anastomosis in 120 patients: there was no significant difference in the incidence of postoperative anastomotic fistula (10% / 16.7%) (P > 0.05). There were differences between the two groups in groups A and B 2 months after surgery(P < 0.05); no significant difference between the two groups 4 months after surgery (P > 0.05). Conclusion Separation of right gastric artery has no effect on anastomotic fistula after esophageal cancer and may cause postoperative anastomotic stenosis in patients.
