本研究分析瓦特乳头癌的淋巴扩散型式和复发方式,以确定外科治疗的对策。 方法:1974至1994年在日本Kanazawa大学医院对36例瓦特乳头癌病人施行了胰十二指肠切除和区域性淋巴结清除术,其中15例还清除了主动脉旁淋巴结。瓦特乳头癌按外形分为3型:隆突型、混合型、溃疡型。隆突型肿瘤又分为两种,显露性(肿瘤细胞显露于十二指肠粘膜)和非显露性(肿瘤细胞限于共同通道内)。
This study analyzed the pattern of lymphatic proliferation and recurrence of watt papillary carcinoma to determine the strategy for surgical treatment. METHODS: Thirty-six patients with watt papillary carcinoma underwent pancreatoduodenectomy and regional lymphadenectomy from 1974 to 1994 at Kanazawa University Hospital in Japan, 15 of which also removed paraaortic lymph nodes. Watt papillary carcinoma is divided into 3 types according to the shape: eminence, mixed type and ulcer type. The tumors of the bulge type are divided into two types. They are revealed (the tumor cells are exposed in the duodenal mucosa) and non-exposed (the tumor cells are limited to the common channel).
