目的 :研究多层螺旋CT仿真结肠镜 (MSCTVC)检查的临床应用价值。材料与方法 :应用MSCTVC和电子结肠镜 (EC)对 30例病人进行检查对照。其中 17例还作了病理学检查。结果 :MSCTVC与EC诊断符合 ,结肠癌 15例 ,息肉 9例(其中 1例息肉直径 6mm) ,囊肿 1例。MSCTVC与EC不符合 5例 ,其中 1例EC未插入升结肠 ,MSCTVC发现升结肠癌 ;1例EC发现多发性息肉 ,MSCTVC发现结肠癌 ;1例EC发现乙状结肠息肉 ,MSCTVC加SSD发现横结肠冗长 ;1例EC插不进 ,MSCTVC发现回盲部癌 ;1例EC发现左半结肠 1个息肉 ,右半结肠插不进 ,MSCTVC发现升结肠、肝曲、脾曲各有 1个息肉。17例作病理学检查 ,MSCTVC和EC诊断为结肠癌者病理诊断为腺癌 9例 ,良恶性不能明确者 2例 ,MSCTVC和EC诊断为息肉者 ,病理学诊断为腺瘤 5例 ,慢性炎症 1例。 30例中 ,3例EC诊断为结肠炎症 ,MSCTVC诊断为正常。 4例EC失败 ,MSCTVC完成检查 ,诊断正常。结论 :MSCTVC对结肠隆起性病变是一种有效的检查方法。
Objective: To study the clinical value of multi-slice spiral CT colonoscopy (MSCTVC). Materials and Methods: 30 patients were examined by MSCTVC and electronic colonoscopy (EC). 17 of them also made pathological examination. Results: The diagnosis of MSCTVC coincided with EC, 15 cases of colon cancer, 9 cases of polyps (1 case of polyp diameter 6mm) and 1 case of cyst. MSCTVC and EC did not meet the 5 cases, of which 1 case of EC was not inserted into the ascending colon, MSCTVC found ascending colon cancer; 1 case of EC found multiple polyps, MSCTVC found colon cancer; 1 case EC found sigmoid colon polyps, MSCTVC plus SSD found transverse long; 1 case of EC was not inserted, MSCTVC found ileocecal carcinoma; 1 case of EC found a polyp left colon, right colon inserted into, MSCTVC found ascending colon, liver song, spleen song each have a polyp. Seventeen cases were pathologically examined. Among them, 9 cases were diagnosed as adenocarcinoma by MSCTVC and EC, 2 cases were benign or malignant by MSCTVC and EC, 5 cases were diagnosed as adenoma by pathology, 5 cases by chronic inflammation 1 case. Among 30 cases, 3 cases of EC were diagnosed as colitis and MSCTVC was normal. 4 cases of EC failure, MSCTVC completed the examination, the diagnosis was normal. CONCLUSIONS: MSCTVC is an effective method for examining colon uplift lesions.
