摘要
目的探讨超声微探头在结肠癌术前诊断中的价值。方法回顾性分析30例结肠癌患者的超声微探头检查结果,并与术后病理对照。结果超声微探头检查显示:结肠癌T1期7例;T2期5例,T3期17例,T4期5例;与术后病理结果对照,肿瘤的T分期诊断准确率为80.0%(24/30),N分期准确率为73.3%(22/30),其中6例癌性狭窄患者T分期准确率为83.3%(5/6),N分期准确性率66.7%(4/6),8例患者根据术前超声微探头检查结果修订的治疗方案最终证实是合理的。结论在结肠镜操作过程中一次完成的微探头超声检查提高了结直肠癌和癌性狭窄病变术前分期的准确性,在结直肠癌治疗方案制订中具有独特价值。
Objective To investigate the value of colonoscopic miniprobe uhrasonography for preoperative staging of colorectal neoplasms. Methods Thirty patients from 2005.11 to 2007.12 performed by miniprobe uhrasonography were included. The result was by compared with its corresponding histopathologic findings of the resected specimens. Results According to TNM staging criteria, miniprobe uhrasonography showed 7 cases in T1,5 in T2,17 in T3 ,and 5 in T4. Compared with the histopathologic findings of the resected specimens, the T and N staging accuracy for colon cancer were 80.0% （24/30） and 73.3 % （22/30）, respectively. Among them, 6 cases with stenotic tumors were staged successfully by miniprobe uhrasonography, with the T and N staging accuracy of 83.3% （5/6） and 66.7% （4/6）, respectively. The therapeutic regimen, modified based on the findings of preoperative miniprobe uhrasonography in 7 cases, was eventually confirmed feasible. Conclusion These preliminary results show that miniprobe uhrasonography during routine colonoscopy improves the accuracy of preoperative staging of stenotic rectal cancer and colonic cancer, and play a special role in the designing therapeutic regimen of colonic cancer.
