【摘要】 目的:通过对乙状结肠癌和直肠癌肠腔脱落细胞的定性研究,了解脱落的癌细胞和上切缘的关系。方法:随机选择41例手术治疗乙状结肠和直肠癌的患者。术毕立即用载玻片于肿瘤上界至上切缘之间行印片,然后用95%的医用酒精固定,行HE染色后读片。结果:6例在肿瘤上界至上切缘之间找到癌细胞,阳性率14.63%,1例找到可疑癌细胞,阳性率2.44%。结论:乙状结肠和直肠癌肿近端肠腔脱落的癌细胞检测阳性提示,有可能是肠吻合术后吻合口复发的潜在因素之一,术前或术中肠腔内无瘤处理是重要的操作环节。更多还原

【Abstract】 Objective: To understand the relationship between rectal cancer cells and the upper margin through the qualitative research of the sigmoid colon and rectal exfoliative cells of intestinal cavity. Methods: 41 cases of patients with sigmoid colon and rectum cancer of surgical treatment were randomly selected. The printed piece was immediately done with the slide between tumor margin and the upper margin after the operation,and then was fixed with 95% of medical alcohol,read piece line after HE staining. Results: The cancer cells in 6 cases were found between tumor margin and the upper margin and the positive rate was 14. 63%; 1 case of suspected cancer cells and positive rate was2. 44%. Conclusion: The proximal sigmoid colon and rectal cancer lumen loss test positive for cancer suggests that intestinal anastomosis is likely to be one of the potential factors of postoperative anastomotic recurrence. The preoperative or intraoperative inner lumen disease-free processing is an important operational details.更多还原
