To facilitate early detection of carcinoma of the gallbladder, a comparative study of macroscopic forms and ultrasonographic (US) features of stage I (TNM staging system) gallbladder cancer was carried out retrospectively in 71 cases of such carcinomas that were resected surgically. Macroscopic forms of the lesions were classified into four types: pedunculated (eight cases), sessile (15 cases), superficial raised (25 cases), and flat (23 cases). Among 71 cases, only 20 were diagnosed preoperatively by means of US. US patterns of the lesions were also classified into four types: fungating mass, lumen filling, smooth raised, and thickening of mucosa. US features corresponded well to the macroscopic forms. No flat lesion was identified preoperatively. For early detection of carcinoma of the gallbladder, it seemed essential to pay careful attention to mild mucosal change, as more than 50% of early cancers did not show apparently protruding lesions.
为便于早期发现胆囊癌，我们对71例经手术切除的Ⅰ期（TNM分期系统）胆囊癌的大体形态和超声（US）特征进行了回顾性比较研究。病变的大体形态分为四种类型：有蒂型（8例）、无蒂型（15例）、浅表隆起型（25例）和平坦型（23例）。71例中，仅20例术前通过超声诊断。病变的超声表现也分为四种类型：蕈伞型肿块、管腔内充盈型、光滑隆起型和黏膜增厚型。超声特征与大体形态吻合良好。术前未发现平坦型病变。对于胆囊癌的早期发现，密切关注黏膜轻度改变似乎至关重要，因为超过50%的早期癌症并无明显突出病变。
