Proximal vs total gastrectomy for proximal advanced gastric cancer / 中华普通外科杂志

ABSTRACT

Objective To investigate the clinical results and prognosis between proximal and total gastrectomy in proximal advanced gastric cancer.Methods The clinicopathological data of 221 patients with proximal advanced gastric cancer who undcrwent radical gastrectomy were retrospectively analyzed.82 patients and 139 patients underwent proximal and total gastrectomy respectively.The number of dessected lymph nodes,postoperative complications and mortality were compared.Kaplan-Meier survival rate curves and Log-rank test were drawn and compared.Results A total of 1 411 (11-34) and 3 345 (14-35) lymph nodes were harvested from the surgical specimens of 82 and 139 patients with proximal and total gastrectomy respectively,the average number of harvested lymph nodes was 17 ± 11 and 24 ± 10 (t =2.586,P ＜0.05).The overall complications in proximal gastrectomy were higher than total gastrectomy (73.2％ vs.30.2％,x2 =38.291,P ＜0.01).The ratio of functional delayed gastric emptying,anastomotic leakage and stenosis,reflux esophagitis in proximal gastrectomy patients was higher than total gastrectomy.The survival rate in proximal gastrectomy were lower than total gastrectomy in proximal advanced gastric cancer (P ＜0.01).Conclusion Total gastrectomy is recommended for proximal advanced gastric cancer.
