Biliary cancers include gallbladder cancer (GBC) and cholangiocarcinoma (CCA). GBC may appear as a mass replacing the gallbladder, thickened gallbladder wall, or polypoid lesion in the gallbladder. Gallbladder polyps with low risk of GBC (eg, 6- to 10-mm polyps without other risk factors) are screened with sonography. In general, polyps smaller than 5 mm are ignored and those larger than 10 mm require surgical consideration. Screening for CCA is less well-established. On imaging, CCA may be divided into mass-forming, periductal infiltrating, and intraductal types. This review discusses the current state of screening and diagnosis of GBC and CCA.
胆管癌包括胆囊癌（GBC）和胆管癌（CCA）。胆囊癌可能表现为取代胆囊的肿块、胆囊壁增厚或胆囊内的息肉样病变。对发生胆囊癌风险较低的胆囊息肉（例如，6至10毫米且无其他风险因素的息肉）进行超声筛查。一般来说，小于5毫米的息肉可不予理会，而大于10毫米的息肉则需要考虑手术治疗。对胆管癌的筛查尚未完全确立。在影像学上，胆管癌可分为肿块型、导管周围浸润型和导管内型。本综述讨论了胆囊癌和胆管癌筛查与诊断的现状。
