[Pancreatic-portal fistula. A rare complication of chronic pancreatitis]. / La fistule pancréatico-portale. Une complication rare de la pancréatite chronique.

We report a 40-year-old patient with complication of chronic pancreatitis as a pancreatico-portal fistula. The patient had subcutaneous nodular fat necrosis of the lower limbs resembling Weber-Christian syndrome, and amylasic ascitis. The diagnosis was established with retrograde endoscopic cholangio-pancreatography which found three pancreatic pseudocysts and a communication with the portal venous system. A portal thrombosis with cavernum was studied with color echo-Doppler and arteriography. The echo-endoscopy was performed for the first time in this complication and its significance estimated. The evolution was quickly and spontaneously favourable. That is a very rare complication of chronic pancreatitis and an expectant conservative management can be adopted.
