随着各项内镜诊断新技术如染色内镜、放大内镜、超声内镜及荧光内镜等的开展,早期胃癌(early gastric cancer,EGC)的检出率不断上升。胃癌外科根治性切除及淋巴结清扫术曾被认为是早期胃癌的首选治疗方法,黏膜内癌和黏膜下癌的外科根治术5年生存率高达99%和96%,但根治性手术相关并发症发生率和死亡率分别高达43%和6.5%,外科根治术后常并发早饱、吞咽困难、反流、腹部不适等症状,术后生活质量与进展期胃癌相似。
With the development of various endoscopic diagnostic techniques such as endoscopy, magnifying endoscopy, endoscopic ultrasonography and endoscopic fluoroscopy, the detection rate of early gastric cancer (EGC) has been increasing. Surgical radical resection of gastric cancer and lymph node dissection has been considered the preferred treatment for early gastric cancer, 5-year survival rate of surgical resection of intramucosal and submucosal cancer as high as 99% and 96%, but the incidence of radical surgery-related complications Rates and mortality rates were as high as 43% and 6.5%, respectively. Postoperative radical prostatectomy was associated with early fullness, dysphagia, reflux, abdominal discomfort, and postoperative quality of life similar to advanced gastric cancer.
