小肠平滑肌肿瘤9例误诊分析

Misdiagnostic Causes of 9 Cases of Intestinal Leiomyosarcoma

目的 :分析小肠平滑肌肿瘤误诊原因。方法 :回顾性病例分析。结果 :12例中误诊胃炎 2例 ,十二指肠球部溃疡 2例 ,胰头癌 2例 ,结肠癌 2例 ,肝炎 1例 ,误诊率占同期病例的 75 %。结论 :小肠平滑肌肿瘤发病率低 ,无特异症状、体征 ,缺乏特异性检查方法易致误诊。临床医师思维中缺乏对该病的认识 ,过分偏信辅助检查或依赖病史诊断是造成误诊的主要原因。排除诊断可减少误诊。临床涉及本病时 ,应放宽手术探查指征 。

Objective To analyse misdiagnostic causes of intestinal leiomyosavcoma.Methods Review case analysis was made.Results The misdiagnosed cases were the following:2 cases of gastritis,2 cases of duodenal bullar ulcer,2 cases of carcinoma of head of pancreas,2 cases of carcinoma of colon and 1 case of hepatitis.The misdiagnostic rate accounted for 75% of homochronous cases (12 cases).Conclusion This disease is easy to misdiagnose,because of its lower incidence,no specific symptoms and signs,and lack of specific examinations.The main reason for misdiagnosis is that clinicians lack the knowledge of this disease,believe in accessory examinations or depend upon case history for diagnosis.We suggest that operational exploration indications should be loosened up for the attainment of the purpose of both diagnosing and treating the disease.
