[Intracystic hemorrhages of pancreatic pseudocysts]

The authors report ten personal cases and review the literature on 99 other cases, and study primary intra-cystic hemorrhage or post-operative hemorrhage, occurring during the course of pancreatic pseudo-cysts. These hemorrhagic pseudo-cysts are very often associated with chronic pancreatitis; they may rupture into a hollow viscus, the peritoneal cavity or into Wirsung's duct. Arteriography and duodenoscopy with retrograde pancreatography, should permit one to reduce the frequency of these latent, undiagnosed forms until surgical operation has been carried out. Even more dangerous, post-operative bleeding often represents a recurrence of primary intra-cystic hemorrhage which has been undiagnosed or neglected. Surgical treatment should give a greater place to operations of excision which simultaneously treat false cyst, the responsible vascular lesion and the chronic casual pancreatitis.
