目的 :探讨胃上部癌术前介入治疗与手术间隔时间的关系 ,以确定最佳间隔时间。方法 :比较 2 5例胃上部癌术前介入治疗后的手术标本的病理切片 ,生存期。结果 :间隔时间≤ 4d的患者 ,病理切片上坏死不明显 ;间隔时间 >10d者 ,可见新生的肿瘤血管 ;间隔时间为 5～ 9d者 ,病理切片上坏死最明显 ,术后生存期最长。结论 :胃上部癌术前接受介入治疗与手术的最佳间隔时间为 5～ 9d。胃上部癌术前介入治疗能提高切除率 ,延长生存时间。
Objective: To investigate the relationship between preoperative interventional treatment of gastric upper neoplasm and surgical interval to determine the optimal interval time. Methods: The pathological sections and survival of 25 surgical specimens of upper gastric cancer after surgical intervention were compared. Results: The patients with interval ≤ 4 days had no obvious necrosis in the pathological section. The neoplasm vessels were seen in the interval> 10 days. The interval between 5 ~ 9 days was the most obvious pathological necrosis and the longest postoperative survival. Conclusion: The optimal interval between preoperative interventional treatment and surgery for upper gastric cancer is 5 ~ 9 days. Preoperative interventional treatment of upper gastric cancer can improve the resection rate and prolong the survival time.
