目的探讨结肠镜下钛夹标记联合腹部平片在大肠癌术前定位的应用价值。方法 75例大肠癌患者随机分为联合定位组和对照组,所有患者均经手术及病理确诊。联合组结肠镜检查发现结肠肿瘤病灶行活检后在瘤体旁组织放置钛夹标记,镜检结束立即腹平片确定钛夹位置而定位,对照组单纯结肠镜检定位,两组定位结果与手术结果比较。结果大肠癌结肠镜下钛夹标记联合腹部平片定位38例,与手术结果符合率100%;对照组定位37例,与手术结果符合率89.19%,两组比较差异有统计学意义(P<0.05)。结论钛夹联合腹平片对大肠癌术前定位准确,可为手术切口及术式的选择提供重要的指导作用。
Objective To investigate the value of colonoscopic titanium clip marking combined with abdominal plain film in the preoperative localization of colorectal cancer. Methods 75 cases of colorectal cancer were randomly divided into joint localization group and control group, all patients were confirmed by surgery and pathology. Combined colonoscopy found colorectal tumor lesions biopsy placed in the tumor tissue placed titanium clamp mark immediately after the end of microscopy to determine the position of the titanium clip position, the control group colonoscopy position, the two sets of positioning results and surgery Results comparison. Results The colposcopic colon biopsy of titanium clip and abdominal plain film were performed in 38 cases, which was consistent with the surgical result of 100%. The control group was located in 37 cases and the coincidence rate was 89.19% with the result of surgery. There was significant difference between the two groups (P < 0.05). Conclusion Titanium clip combined with abdominal plain film preoperatively for colorectal cancer positioning accuracy, which can provide important guidance for surgical incision and surgical options.
