目的　探讨空回肠间质瘤的诊断和治疗经验。方法　对我院 1993年 10月～ 2 0 0 4年 1月收治的有完整资料的 13例空回肠间质瘤病例进行回顾性分析 ,本组患者均经术后病理和免疫组化证实。结果　本组患者主要临床表现为消化道出血、腹痛。发病至确诊时间 2个月至 7年。剖腹探查确诊 7例 ,腹腔镜腹腔探查确诊 4例 ,术前确诊的仅 2例。随访 2个月至 9年 ,除 1例死于其它疾患外 ,余 12例均健在 ,无空回肠间质瘤复发病例发现。结论　小肠间质瘤预后甚好 ,但本病缺乏特征性的临床表现及有效的诊断手段 ,易致长期延误诊治 ;对长期不明原因的消化道出血患者 ,及早行剖腹探查或腹腔镜腹腔探查是避免小肠间质瘤长期延误诊治 ,改善患者预后的关键 Objective To investigate the diagnosis and treatment experience of ileolipitoma. Methods A retrospective analysis of 13 cases of Ileum interstitial aneurysms with complete data in our hospital from October 1993 to January 2004 was performed. The patients were confirmed by postoperative pathology and immunohistochemistry. Results The main clinical manifestations of this group of patients with gastrointestinal bleeding, abdominal pain. The onset of time to diagnosis of 2 months to 7 years. 7 cases were diagnosed by laparotomy, 4 cases were diagnosed by laparoscopy and 2 cases were diagnosed preoperatively. All patients were followed up for 2 months to 9 years. Except for 1 patient who died of other diseases, more than 12 patients were alive without recurrent ileum stromal tumors. Conclusion The prognosis of intestinal stromal tumor is very good, but the disease lacks characteristic clinical manifestations and effective diagnostic methods, easy to cause long-term delay diagnosis and treatment; long-term unexplained gastrointestinal bleeding in patients with early laparotomy or laparoscopic abdominal exploration is Avoid the long-term delayed diagnosis and treatment of small intestinal stromal tumor, improve the prognosis of patients
