目的:探讨多层螺旋CT (multi‐slice spiralCT ,MSCT )及电子肠镜对结肠Crohn病诊断价值及其限度。方法回顾性分析经手术、病理、临床证实的结肠Crohn病的MSCT及电子肠镜的表现,重点评价两种方法对病变的显示情况。结果17例M SC T检查,多节段病变17例(100%),病变仅累及结肠8例(47.1%),同时累及结肠和小肠9例(52.9%),共累及57个结肠段,表现为肠壁增厚(>4mm)17例(100%),强化增加(>20HU )17例(100%),肠腔不规则狭窄6例(35.3%),系膜区淋巴结肿大(>5mm)13例(76.5%),肠系膜血管增多(梳征)16例(94.1%),肠管周围蜂窝织炎7例(41.2%),腹腔内脓肿1例(5.9%),腹腔积液5例(29.4%),瘘管1例(5.9%)。16例电子肠镜检查,表现为裂隙状溃7例(43.8%),铺路石征10例(62.5%),肠腔狭窄7例(43.8%),多节段性病变15例(93.8%)。结论结肠Crohn病的M SC T表现有一定特征性,可多方位观察肠壁、肠周病变,但难以显示肠内裂隙状溃疡和铺路石征。电子肠镜易于显示黏膜纵行裂隙状溃疡和铺路石征等特征性改变,但不能显示肠壁病变及肠周并发症。两种检查方法相互结合,可提高结肠Crohn的诊断率。
目的:探討多層螺鏇CT (multi‐slice spiralCT ,MSCT )及電子腸鏡對結腸Crohn病診斷價值及其限度。方法迴顧性分析經手術、病理、臨床證實的結腸Crohn病的MSCT及電子腸鏡的錶現,重點評價兩種方法對病變的顯示情況。結果17例M SC T檢查,多節段病變17例(100%),病變僅纍及結腸8例(47.1%),同時纍及結腸和小腸9例(52.9%),共纍及57箇結腸段,錶現為腸壁增厚(>4mm)17例(100%),彊化增加(>20HU )17例(100%),腸腔不規則狹窄6例(35.3%),繫膜區淋巴結腫大(>5mm)13例(76.5%),腸繫膜血管增多(梳徵)16例(94.1%),腸管週圍蜂窩織炎7例(41.2%),腹腔內膿腫1例(5.9%),腹腔積液5例(29.4%),瘺管1例(5.9%)。16例電子腸鏡檢查,錶現為裂隙狀潰7例(43.8%),鋪路石徵10例(62.5%),腸腔狹窄7例(43.8%),多節段性病變15例(93.8%)。結論結腸Crohn病的M SC T錶現有一定特徵性,可多方位觀察腸壁、腸週病變,但難以顯示腸內裂隙狀潰瘍和鋪路石徵。電子腸鏡易于顯示黏膜縱行裂隙狀潰瘍和鋪路石徵等特徵性改變,但不能顯示腸壁病變及腸週併髮癥。兩種檢查方法相互結閤,可提高結腸Crohn的診斷率。

Objective To investigate the value and limits of MSCT and electronic colonoscope in the diagnosis of Crohn’ s disease of colon .Methods MSCT and electronic electronic colonoscope date of colon Crohn’s disease ,which were prov‐en by surgery ,pathology and clinic ,were retrospectively analysed .Both methods focused on the evaluation of the lesion display .Results Of the 17 cases of MSCT ,17 cases (100% ) showed multi‐segment lesions ,8 cases (41 .7% ) had lesions limited in colon ,9 cases (52 .9% ) had simultaneous colon and small intestine involvement .There were a total of 57 seg‐ments of colon involved .Among the 17 cases ,there were 17 cases (100% ) of mural thickening (> 4 mm) ,17 cases (100% ) of increased enhancement of bowel wall (>20~30 HU) ,6 cases (35 .3% ) of irregular intestine stenosis ,13 ca‐ses (76.5% ) of mesangial region lymphadenectasis (> 5 mm ) ,16 cases (94 .1% ) of increased mesenteric vascularity (“comb”sign) ,7 cases (41 .2% ) of dermatocellulitis ,1 case (5 .9% ) of peritoneal abscess ,5 cases (29 .4% ) of seroper‐itoneum ,1 case (5 .9% ) of fistulization .Among the 16 cases of electronic colonoscope ,7 cases (43 .8% ) of strip ucers , 10 cases (62.5% ) of cobblestone ,there were 7 cases (43 .8 .7% ) of intestine stenosis ,15 cases (93 .8% ) of skip lesions . Conclusion The MSCT findings of colonic Crohn’s disease are characteristic ,which have advantages in demonstrating bowel wall and extraintestinal complication of Crohn’s disease ,but cann’t demonstrate strip ucers and cobblestone .The electronic colonoscope is easy to demonstrate the characteristic changes of Crohn’s disease such as strip ucers and cobble‐stones ,but it is difficult to demonstrate bowel Wall and extraintestinal complication .The two diagnosic methods are com‐bined ,which can improve the diagnosis of Crohn’s disease of Colon .
