诊断性腹腔镜检已用作胰头癌的分期,有时可检出小的肝转移灶和腹膜病灶沉积,腹腔镜超声探头的引进更可检查实质器官和后腹膜间隙有无小的肝转移灶和病灶局部长入大血管而不受肠道气体的干扰.作者首先应用腹腔镜B超检查以进一步对胰头癌作出分期.作者取13例壶腹癌和60例胰头癌作术前内镜逆行性胰胆管造影和多普勒超声扫描,判定为Ⅰ期肿瘤.70例在腹腔镜检作胆道内支撑引流术.69例的 Diagnostic laparoscopy has been used as a staging of the pancreatic head cancer, and sometimes small deposits of hepatic metastases and peritoneal lesions can be detected. The introduction of a laparoscopic ultrasound probe can also check the presence of small liver metastases in the parenchymal organ and the posterior peritoneal space. And lesions grow into large blood vessels without interference from the intestinal gas. The author first applied laparoscopic B-ultrasound to further stage cancer of the pancreatic head. The authors took 13 cases of ampulla cancer and 60 cases of pancreatic head cancer preoperatively Retrograde contrast-enhanced cholangiopancreatography and Doppler ultrasonography were identified as stage I tumors. Seventy-nine patients underwent laparoscopic biliary stent drainage. 69 cases
