The additional value of laparoscopic ultrasonography was evaluated prospectively in 35 patients undergoing diagnostic laparoscopy for a suspected potentially resectable proximal bile duct tumor. Findings were compared with transabdominal ultrasonography, laparoscopy, surgery, and pathology. Laparoscopic ultrasonography was able to visualize the presence and origin of small bile duct tumors or stones and small liver metastases, which could not be seen or could be visualized only doubtfully by ultrasonography and laparoscopy. Laparoscopic ultrasonography was more useful in staging of small tumors of the gallbladder or proximal common bile duct than in staging bifurcation (Klatskin) tumors. Additional information provided by laparoscopic ultrasonography led to a change in diagnosis or tumor stage in eight patients (23%) and to avoidance of laparotomy in three patients (9%).
前瞻性评估了35例因疑似可切除近端胆管肿瘤而行诊断性腹腔镜检查患者的腹腔镜超声检查的附加价值。将检查结果与经腹超声、腹腔镜检查、手术及病理结果进行比较。腹腔镜超声能够显示小胆管肿瘤或结石以及小肝转移灶的存在和起源，而经腹超声和腹腔镜检查无法看到或仅能可疑显示这些情况。腹腔镜超声在胆囊或近端胆总管小肿瘤的分期中比在肝门部（克氏）肿瘤分期中更有用。腹腔镜超声提供的额外信息使8例患者（23%）的诊断或肿瘤分期发生改变，并使3例患者（9%）避免了开腹手术。
