将一个直径为4厘米宽的特制直肠镜,从患者肛门插入到直肠,从直肠镜上的四个通道中分别插入立体视镜和手术器械,医生在立体视镜下借助手术器械将肿瘤完整切除。这是北京协和医院基本外科在国内率先开展的治疗直肠肿瘤的最新技术——经肛门内镜显微手术。该项新技术的引进,使一些原本只能开腹才能完成的直肠腺瘤、早期直肠癌等手术被微创手术所取代。最大优点是创伤小、术后复发率低、并发症发生率低、住院时间短。70岁高龄的北京患者张大爷,一年前出现无诱因便血,大便常带有少量鲜红色血液。去年12月到北京协和医院就诊,检查发现距肛门7厘米处有一个2×3厘米的息肉,诊断为直肠绒毛腺管状腺瘤,医院给予圈套器切除。3个月后患者病情复发,再次到北京
A special 4 cm-wide proctoscope was inserted from the anus of the patient to the rectum. Stereoscopy and surgical instruments were inserted from the four channels on the proctoscope. The surgeon used a surgical instrument to remove the tumor completely under the stereoscope. . This is the most advanced technique for the treatment of rectal tumors first performed in China by the Department of Basic Surgery at Peking Union Medical College Hospital - transanal endoscopic microsurgery. The introduction of this new technology has replaced some of the operations such as rectal adenoma and early rectal cancer that could only be completed by laparotomy, with minimally invasive surgery. The biggest advantages are minimal trauma, low postoperative recurrence rate, low complication rate, and short hospital stay. Zhang Daye, a 70-year-old patient in Beijing, had bloodless stools a year ago. She often had a small amount of bright red blood. In December last year, he went to Peking Union Medical College Hospital for treatment. He found that there was a 2 x 3 cm polyp 7 cm from the anus. He was diagnosed as a rectal villous tubular adenoma, and the hospital was given a snare to remove it. Three months later, the patient relapsed to Beijing again
