作者报告小肠类癌18例。男10例,女8例。年龄40～69岁。肿瘤位于回肠者17例,空肠1例。最常见临床症状为不同程度的小肠梗阻的腹痛,4例临床及化验所见考虑有类癌综合征。X 线征,3例于远端回肠显示光滑、孤立的壁内充盈缺损(若肿瘤继续向腔内增长,可造成梗阻)。此需与粘膜或粘膜下的良性肿瘤、异位胃粘膜或孤立转移相鉴别。约1/3病例呈多发、大小不等、结节状充盈缺损,可能为由原发病变转移至小肠其他
The authors reported 18 cases of intestinal cancer. There were 10 males and 8 females. Age 40 to 69 years old. The tumor was located in the ileum in 17 cases and in the jejunum in 1 case. The most common clinical symptoms are abdominal pain with varying degrees of small bowel obstruction, and four cases of clinical and laboratory investigations considered carcinoid syndrome. X-ray sign, 3 cases showed a smooth, isolated in-wall filling defect in the distal ileum (if the tumor continues to grow into the cavity, it can cause obstruction). This needs to be differentiated from mucosal or submucosal benign tumors, ectopic gastric mucosa, or isolated metastases. About 1/3 of cases are multiple, different in size, nodular filling defect, may be from the primary lesion to other small intestine
