title: [Ultrasound diagnosis of extrahepatic portal hypertension in chronic pancreatitis].
abstract: OBJECTIVE
  To evaluate the potential of the color duplex scanning in revealing of the portal hypertension in patients with chronic pancreatitis.
  
  
  METHODS
  94 patients with chronic pancreatitis were investigated. In 61 patients (65%) pancreatitis was complicated by extrahepatic portal hypertension (EHPH) and 31 patients (35%) were without signs of rising of the portal pressure.
  
  
  RESULTS
  Investigations in B-regime have shown that in patients with EHPH chronic calculous pancreatitis was revealed in 48%, development of pancreatic hypertension in 75%, increase of the pancreas head up to more than 40 mm in 58% of patients. We did not reveal statistically significant differences in pseudo-cysts in pancreas, extension of extrahepatic and intrahepatic ducts and infiltrative changes in parapancreatic cellular tissue in patients with and without EHPH. A development of EHPH in 31 (51%) patients was preconditioned by an extravasal compression of veins of portal system, combination of extravasal compression with thrombosis was found in 11 (18%) patients, in 12 (20%) patients thrombosis of the magistral veins of portal system was revealed and in 7 (11%) patients hemodynamics was not changed. Resections were found to be preferable operations for recovery of portal circulation. Increase and normalization of portal circulation found after transversal section of pancreas (Beger operation, pancreo-duodenal resection, distal resection of pancreas). A tendency to normalization of the blood flow was observed after the Frey operation.
