30例原发性小肠肿瘤的临床分析

目的：探讨原发性小肠肿瘤的临床特点及诊断方法方法：(1)收集本院1998年1月至2003年10月间治疗的30例原发性小肠肿瘤(不包括十二指肠肿瘤)的临床资料进行回顾性分析(2)通过小肠气钡对比双重造影、腹部CT、选择性肠系膜上动脉造影及B超等检查方法的对比。(3)结合手术病理证实结果：临床表现有：腹痛19例，消化道出血9例，腹部包块7例，肠梗阻3例，贫血2例，消瘦2例临床诊断为：空肠肿瘤18例，回肠肿瘤11例，空、回肠同时发生的1例平滑肌肉瘤16例，腺癌3例，间质瘤3例，黏膜相关恶性淋巴瘤3例，类癌2例，鳞癌1例，平滑肌瘤1例，恶性黑色素瘤1例。结论：小肠气钡对比双重造影是目前小肠肿瘤最有价值的诊断方法对诊断困难的消化道出血，选择性肠系膜上动脉造影可作为常规检查方法CT对诊断小肠肿瘤有一定的帮助．B超诊断率低。

Clinical Analysis of Primary Small Intestinal Tumor in 30 Cases

Objective:To analyze the clinical characteristics and diagnosis of the primary small intestinal tumor. Methods: (1) The clinical data was collected from 30 patients with primary small intestinal tumor and retrospective analysis was made.(2)Small intestine double contrast radiography, abdomen CT,selective superior mesenteric artery radiography and abdomen B ultrasound were compared. (3)The data were confirmed by surgical pathology. Result:The clinical manifestations were stomachache in 19 cases,gastrointestinal hemorrhage in 9 cases,abdomen mass in 7cases,intestinal obstruction in 3 cases,anemia in 2 cases and weight loss in 2 cases.There were 18 jejunal tumor, 11 ileal tumor and 1 jejunoileal tumor by clinical diagnosis. And 16 leiomyosarcomas, 3 adenocarcinomas, 3 interstitialomas, 3 mucosa-associated malignant lymphomas, 2 carcinoids, 1 squamous carcinoma, 1 leiomyoma and 1 malignant melanoma were diagnosed by pathology. Conclusion: Small intestine double contrast radiography was the best diagnosis method to primary small intestinal tumor at present.And the selective superior meserteric angiography can be a routine diagnosis method to unkown gastrointestinal bleeding. CT may help to diagnose small intestinal tumor. But the diagnosis rate of B ultrasound was low.
