为了探讨原发性小肠肿瘤所致肠套叠的诊断和治疗特点，对８６例因原发性小肠肿瘤所致的肠套叠进行了临床分析，其中良性肿瘤３９例（４５．４％），主要分布在空肠，多系平滑肌瘤、腺癌和脂肪瘤；恶性肿瘤４７例（５４．６％），主要分布在回肠，多系恶性淋巴瘤、腺癌和平滑肌肉瘤。套叠为顺套８１例（９４．２％），逆套５例（５．８％）；单套６２例（７２．１％），复套２４例（２７．９％）。术前确诊３８例（４４．２％）。治愈７９例（９１．９％）。随访６６例，３７例恶性肿瘤术后２年和５年生存率分别为８１％和４０．５％。作者结合文献对原发性小肠肿瘤所致肠套叠的特点、诊断及治疗进行了较全面的讨论，并详述了原发性小肠肿瘤的病理类型以及与肠套叠的关系。
To investigate the characteristics of diagnosis and treatment of intussusception caused by primary small bowel tumors, 86 cases of intussusception caused by primary small bowel tumors were clinically analyzed, including 39 benign tumors (45.4%). Mainly distributed in the jejunum, mostly leiomyoma, adenocarcinoma and lipoma; malignant tumors in 47 cases (54.6%), mainly in the ileum, multiple lines of malignant lymphoma, adenocarcinoma and leiomyosarcoma. Overlays were 81 cases (94.2%) in the direct sleeve, 5 cases (5.8%) in the reversed sleeve, 62 cases (72.1%) in the single sleeve, and 24 cases (27.9%) in the double sleeve. Preoperative diagnosis of 38 cases (44.2%). 79 cases (91.9%) were cured. Follow-up was performed in 66 patients. The 2-year and 5-year survival rates of the 37 cases of malignant tumors were 81% and 40.5%, respectively. The author combined the literature to discuss the characteristics, diagnosis and treatment of intussusception caused by primary small bowel tumor. It also detailed the pathological type of primary small bowel tumor and its relationship with intussusception.
