上消化道同时性多原发性肿瘤漏诊原因及其防治——附28例分析

目的：探讨上消化道同时性多原发性肿瘤漏诊原因及其防治措施。方法：结合文献对28例经手术病理证实的上消化道同时性多原发性肿瘤作了分析，比较了X线钡餐透视及内窥镜检查等在上消化道同时性多原发性肿瘤中的诊断作用。结果：28例中术前确诊者仅8例（28．57％），其余20例全部系在术中或术后发现。经比较发现内窥镜的诊断率要高于钡透（P＜0．01）。结论：对该病不认识及警惕性不高是造成漏诊的主要原因，钡透时仔细观察上消化道全貌；全面地内窥镜检查及扩大切除范围等可以减少或防止肿瘤漏诊。

Missed Diagnosis and Prevention of Multicentric Tumors of Upper Alimentary Tract-Report of 28 Patients

: Objective To investigate the reason of missed diagnosis and preventive measure aboutmulticentric tumors of upper alimentary tract. Methods: 28 patients with multicentric tumors of upperalimentary tract were reported in this paper. All were compared by X-ray, endoscope and explored oper- ation to diagnose the multicentric tumors of upper alimentary tract. Results: The diagnostic rate of theendoscope was higher than X-ray (P<0. 01 ). Before operatin the symptom of disease must be attented.There were determined diagnosis of 8 cases 28. 57% in preoperation. Twenty cases were diagnosed inpostoperation. In operation the upper alimentary tract must be carefully examinated. The speed frozensection were made to suspicious and to expand the resective scope of tumor. Conclusions: It was veryimportant that the careful oberservation was done when the examination of X-ray, endodcope and opera-tion was performed.
