Pancreatoscopy-guided electrohydraulic lithotripsy in a patient with calcific chronic pancreatitis

摘要

Figure 1. A, B, Contrast-enhanced CT images in a patient with chronic calcific pancreatitis. A, Enlarged pancreatic head with multiple parenchymal and intraductal calcifications (arrow). B, Atrophic and heterogeneous pancreas with multiple parenchymal calcifications and ductal stones. C, Initial pancrea- togram showing markedly dilated pancreatic duct, multiple filing defects, an obstruction in the head (asterisk), and a pronounced obstruction in the distal body (arrows). D, Pancreatoscopic digital image of the distal pancreatic body showing obstruction of lumen caused by large intraductal stones. E, Pancreatoscopic digital image of the distal body stricture (arrow), which was revealed after pancreatoscopy-guided intraductal lithotripsy.
