目的 探讨小肠血管瘤和血管畸形的临床病理特征和病理诊断。方法 对51例十二指肠、空肠及回肠的血管瘤和血管畸形进行回顾性研究。结果 过去30年中诊断的51例小肠血管瘤和血管畸形中,患者年龄1 4~75 0岁,平均年龄与中位年龄均为40岁;男女性别比无差异;病变部位主要为回肠(18例)和空肠(16例),共占66 7%;主要临床症状是下消化道出血及肠梗阻;大体类型有息肉型、浅溃疡型、血管曲张型、包块型、弥漫浸润型及隐匿型,多为单发;组织学表现以动静脉血管瘤,又称动静脉畸形居多,占86 3% (44 /51例),其他类型还有海绵状血管瘤、毛细血管瘤、遗传性出血性毛细血管扩张症及Dieulafoy病等。结论 小肠血管瘤和血管畸形的组织学诊断困难,必须结合临床及动脉造影结果。
Objective To investigate the clinicopathological characteristics and pathological diagnosis of small intestinal hemangiomas and vascular malformations. Methods 51 cases of duodenal, jejunum and ileum hemangiomas and vascular malformation were retrospectively studied. Results Among the 51 cases of small bowel hemangiomas and vascular malformations diagnosed in the past 30 years, the age ranged from 14 to 75 years. The average age and median age were 40 years old. There was no difference in sex ratio between men and women. The main lesion was ileum Cases) and jejunum (16 cases), accounting for a total of 66.7%. The main clinical symptoms were lower gastrointestinal bleeding and intestinal obstruction. The general types were polyp type, shallow ulcer type, varicose type, mass type, diffuse infiltration type and occult Type, mostly single; histological manifestations of arteriovenous hemangioma, also known as arteriovenous malformations, accounting for 863% (44/51 cases), other types of cavernous hemangioma, capillary hemangioma, hereditary bleeding Telangiectasia and Dieulafoy disease. Conclusions Histopathological diagnosis of intestinal hemangiomas and vascular malformations is difficult and clinical and angiographic findings must be combined.
