逆行胰胆管造影(ERCP)对胰腺疾病的诊断还存在三个问题:1.部分慢性胰腺炎及胰腺癌均可见主胰管狭窄伴二、三级管扭曲,不易鉴别;2.小于2mm的小囊性扩张及二、三级管不规则可能是老年人的正常变异,难于与轻度慢性胰腺炎区别;3.早期胰腺疾病的ERCP可能正常。在行ERCP时,通过内窥镜下主胰管插管(ECMPD)采集纯胰液(PPJ)检查,可有助于鉴别诊断。兹就近年部分有关文献综述如下。标本采集及处理纯胰液的采集可在逆行胰管造影前或后进行。欲作胰腺外分泌的生化检查时,因抗胆碱能药物、ERCP操作及造影剂皆可影响检查结果,可在留置胰管导管1小时后采
There are three problems in the diagnosis of pancreatic diseases by retrograde cholangiopancreatography (ERCP): 1. Some of the chronic pancreatitis and pancreatic cancer can be seen in the main pancreatic duct stenosis with second and third tube distortion, difficult to identify; 2. Smaller than 2mm The cystic dilatation and irregularity of the second and third grade can be the normal variation of the elderly, and it is difficult to distinguish from mild chronic pancreatitis. 3. The ERCP of early pancreatic diseases may be normal. At the time of ERCP, the collection of pure pancreatic juice (PPJ) through the endoscopic pancreatic duct cannula (ECMPD) can help with differential diagnosis. Here is a summary of some relevant literature in recent years. Specimen Collection and Processing Collection of pure pancreatic juice can be performed before or after retrograde angiography. For biochemical tests of pancreatic exocrine secretion, anticholinergic drugs, ERCP procedures, and contrast agents can all affect the test results and can be taken 1 hour after indwelling the pancreatic duct.
