外科手术仍然是食管癌患者首选的治疗方法。现在可耐受食管癌切除手术病人的手术死亡率低于5％,然而五年生存率仍低于20％,许多病人死于复发。食管次全切除术后吻合口复发率约8％～12％。术后吻合口复发似乎与切缘清除率有关,如果保证术中切线足够远,降低残端复发率是可能的。困难的是如何术中精确 Surgery is still the preferred treatment for patients with esophageal cancer. The operative mortality rate of patients who can tolerate esophageal cancer resection is less than 5%. However, the five-year survival rate is still lower than 20%, and many patients die of relapse. The recurrence rate of anastomosis after subtotal esophagectomy is about 8% to 12%. Postoperative recurrence of anastomosis appears to be related to margin clearance. If the tangent line during surgery is sufficiently long, it is possible to reduce the recurrence rate of the stump. What’s difficult is how to be precise during surgery
