探讨肠粘连束带腹内疝的CT表现特点，提高术前早期诊断水平。

回顾性分析2001年1月至2017年3月，贵州医科大学附属医院经手术、病理证实为肠粘连束带腹内疝21例患者的临床与CT检查资料，同时有3例行多期增强CT，15例行腹部立位平片检查。在飞利浦影像工作站2位腹部放射高级职称医师双盲法评价图像。

术前21例患者均有程度不等的腹胀腹痛等肠梗阻症状，术前CT诊断小肠梗阻21例，提示肠粘连束带腹内疝3例，肠管绞窄5例，术前诊断符合率14.29%，漏诊率为85.71%。所有患者均手术证实小肠梗阻，肠管绞窄9例，11例合并肠扭转，1例合并腹茧症。主要影像表现包括：局部明显粘连伴束带形成21例（100%），局限性肠梗阻21例（100%），肠管异位21例（100%），无疝囊（100%），占位征象/周围脏器移位21例（100%），鸟嘴征13例（61.90%），缆绳征/漩涡征17例（80.95%），肠壁增厚伴肠周明显渗出15例（71.43%）。肠粘连束带腹内疝的CT表现特征与手术结果存在相关性。

肠粘连束带腹内疝CT表现具有一定特点，提高认识并熟知其影像征象对早期诊断至关重要。

To investigate the features of imaging findings of internal adhesion band abdominal hernia (ABAH), in order to improve the understanding and the early diagnosis efficacy of ABAH before operation.

Retrospective analysis of clinical data and imaging findings were performed among 21 patients (10 males and 11 females with the age ranging from 4 to 81 years old) with ABAH proved by surgery from January 2001 to March 2017. All cases underwent multidetector computed tomography (MDCT) scan, including 3 casesofmultiphase dynamic contrast-enhanced CT scan and 15 casesabdominal plain film. The images were reviewed independently by two expert radiologistswith double-blind method.

Intestinal obstructionoccurred in all the 21 patients with CT examination, included strangulated intestine obstruction (n=5) and ABAH (n=3) before operation, 3 cases (14.29%) were correctly diagnosed and 18 cases (85.71%) were misdiagnosed before operation. All of 21 cases were confirmed ABAH and intestinal obstruction, included intestinal twist (n=11), intestinal strangulation obstruction (n=9), and abdominal cocoon (n=1) after operation. CT findings of ABAH were significantly characterized by obvious local adhesion band formation and were correlated with results of operation, other imaging signs of ABAH included bowel obstruction (100%), ectopic bowel (100%), sign of space occupying (100%), stretched, engorged, and twisted mesenteric vessels (n=17, 80.95%), beak sign of bowel loops wereclustered and twisted (n=13,61.90%), and bowel wall thickening with obvious exudation around in 15 cases (71.43%). Butsign of space occupying was relatively less degree than other abdominal hernia.

Early diagnosis of ABAH is difficult before operation in clinic, but it isincreasingly significant. CT examination with certain characteristic findings is of significant importancefor early diagnosis, Misdiagnosis of ABAH mainly due to insufficient disease awareness and lack of relevant knowledge.
