胰头、壶腹周围癌(后者包括胆总管下段癌、壶腹癌、十二指肠乳头癌)临床表现相似,但手术切除率和术后生存率不同,近年来影像学诊断技术进展迅速,术前将胰头壶腹周围不同部位肿瘤分开已完全成为可能。本文就近期经手术,病理证实的6例胰头壶腹周围癌术前影像学资料综合分析,探讨术前影像学检查的临床意义。 Pancreatic head, ampullary carcinoma (the latter including common bile duct carcinoma, ampullary carcinoma, duodenal papillary carcinoma) clinical manifestations similar, but the surgical resection rate and postoperative survival rate in recent years, imaging diagnosis of rapid progress , Preoperative pancreatic ampulla around different parts of the tumor has been completely possible. In this paper, the recent operation, pathology confirmed in 6 cases of pancreatic periampullary carcinoma preoperative imaging data comprehensive analysis of the clinical significance of preoperative imaging examination.
