直径2cm以下的小胰癌不一定是早期癌,但小胰癌长期生存者较多确是事实。作者收治178例,其中直径2cm以下的11例小胰癌全是胰头癌。其影像检查结果见表。作者认为,US,CT对小胰癌的定位诊断价值不大。而ERCP的8例中有6例出现主胰管断裂、扩张等表现对肿瘤的定位诊断有用。诊断小胰癌时须采用超选择性血管造影,显示2级以上分支。组内施行这种造影的9例均阳性,切除标本的研究表
Small pancreatic cancer with a diameter of 2 cm or less is not necessarily an early stage cancer, but long-term survivors of small pancreatic cancer are indeed more facts. The authors treated 178 cases, of which 11 cases of small pancreatic cancer with a diameter of 2 cm or less were all pancreatic cancer. The image inspection results are shown in the table. The authors believe that US and CT have little value in the diagnosis of small pancreatic cancer. In 6 out of 8 cases of ERCP, the presence of main pancreatic duct rupture, dilation and other manifestations were useful for the diagnosis of tumor location. Superselective angiography must be used for the diagnosis of small pancreatic cancer, showing grade 2 or higher branches. Nine of the patients who underwent this type of angiography were positive and the specimens were resected.
