目前国内外学者认为肿瘤下缘距齿状线<3cm低位直肠癌应采取的根治术是Miles术或改良Bacon手术。二年来我们对30例癌体距齿状线<3且≥1cm低位直肠癌患者,应用GF—1型管状吻合器行保留肛门括约肌、结肠和肛管皮肤吻合术,近期疗效满意,报告如下。临床资料一般资料。本组男性12例,女性18例,最大年龄72岁,最小年龄31岁,平均年龄51岁,年龄在50岁以上18例,占60%。直肠腺癌28例,高分化26例,中分化2例,低分化2例。粘液癌2例;肿瘤下缘距齿线1—2cm16例,2—3cm14例。病理分期见(附表)。 At present, scholars at home and abroad believe that the radical surgery for low rectal cancer with a dentate line <3cm below the dentate line is Miles or modified Bacon. In the past two years, we have performed GF-1 tubular anastomosis to preserve anal sphincter, colon, and anal canal anastomosis in 30 patients with rectal cancer whose dentate line was <3 and ≥1 cm in height. The short-term efficacy was satisfactory. The report is as follows. Clinical data general information. This group of 12 males and 18 females, the maximum age of 72 years, the minimum age of 31 years, the average age of 51 years old, aged over 50 years in 18 cases, accounting for 60%. There were 28 cases of rectal adenocarcinoma, 26 well-differentiated, 2 moderately differentiated and 2 poorly differentiated. There were 2 cases of mucinous carcinoma; the lower margin of the tumor was 1-2cm from the dentition line and 14 cases from the 2-3cm. See the pathological stage (attached table).
