腔内型食管癌的X线诊断

The X-ray diagnosis of intraluminal esophageal carcinoma

目的探讨腔内型食管癌的X线诊断。方法15例腔内型食管癌均为手术病理证实。全部病例均行食管造影或双对比造影检查。结果X线表现为结节状,息肉状,梭形或不规则形充盈缺损影,表面可见条状及斑片状钡斑,肿瘤直径大于食管腔时,局部管腔呈梭形扩张,大多数腔壁线完整,食管粘膜增粗、紊乱,部分破坏消失。结论此型食管癌虽然多数肿瘤较大,但浸润较浅,侵及粘膜层及粘膜下层和部分肌层者多见,无明显外侵,因而手术切除率高,预后较佳。

Objective To discuss the X-ray diagnosis of intraluminal esophageal carcinoma.Methods Esophagography and double-contrast roentgenography were performel in 15 patients with infraluminal esophageal carcinoma.Which were confirmed by post-surgical pathological examination.Results Nodular lesion,polypous mass,fuseform or irregular filling defects were revealed. Stripe and patch of barium opacifieation were observed on the surface of esophageal mucosa.local esophageal lumen was dalated by a large tumor,while the esophageal wall remained intact in most of the cases.mucosal folds were thiclecned or eroded in several cases.Conclusion The infiltration of the intraluminal esophageal carcinoma are usually limited within superficial layers of the esophageal wall, including mucosa,submucosal layer and partial muscle layer,though the tumor often appears bulky. Since the extra-esophageal inrolrement of intraluminal esophageal carcinoma is uncommon, the resection rate is relatirely high ,making a letter prognosis.
