摘要
目的结合可视人项目和CT图像,研究急性复发性胰腺炎(RAP)时胰液经各膈肌裂孔进入纵隔的通道。方法基于中美可视人项目数据库,利用多平面重建技术,探究通向纵隔的潜在通道。在51例RAP病例CT图像上,这些潜在通道被证实或被纠正。结果除了从系膜后平面、肾后平面经主动脉裂孔进入膈脚后间隙(RCS)的这条通道外,所有可视人展示的进入纵隔的通道均在CT图像得到证实。胰液从胰周间隙(PPS)直接至胃裸区(GBA),或在此过程中途经系膜后平面;随后经食管裂孔进入RCS的R1和R2通道的出现率分别为27.4%和29.0%。结论伴随着RAP病程,通向纵隔的通道有转变成瘘管的可能性,对此类通道的研究,为提高胰胸膜瘘(PPF)的诊断准确率奠定了影像解剖学基础。
Objective To study the channels for pancreatic juice to get into the mediastinum through the diaphragmatic hiatus during recurrent acute pancreatitis（ RAP） in combination with visible human project and CT image. Methods Based on the database of US-China Visible Human Project,multi-planar reconstruction technique is used in order to explore the potential channels for pancreatic juice to get into the mediastinum. On the CT images of 51 patients with RAP,these potential channels were confirmed or corrected. Results Except the channel getting into rear crus space（ RCS） from prerenal and postrenal fascial planes through aortic hiatus,all other channels getting into the mediastinum shown in the visible human project were demonstrated in the CT image. The pancreatic juice got directly into the gastric bare area（ GBA） from the peripancreatic gap（ PPS） or passed through the postrenal fascial plane in the process; the rate of occurrence of pancreatic juice getting into channels R1 and R2or RCS through esophageal hiatus later were 27. 4% and 29. 0%,respectively. Conclusion Along with the course of RAP,it is possible for the channel to the mediastinum to be transformed into fistula.The study on such channels will provide image anatomy basis for improving the diagnostic accuracy of pancreatic-pleural fistula（ PPF）.
