Pancreatic pseudocysts causing compression symptoms.

The authors survey the surgical treatment of duodenal or choledochal stenosis which were detected during the operation of 991 pancreatic pseudocysts in the period of 5 years, from 1987 to 1992, at 850 patients. They found that in the case of common occurrence of mechanical jaundice and pancreatic pseudocyst in 40% of cases the drainage or resection of pseudocyst was enough to ensure the free biliary passage. In case of combined operation the stenosis of choledochus was solved in 64% of cases with sphincteroplasty. In case of common occurrence of duodenal stenosis and pancreatic pseudocyst the drainage of pseudocyst was enough in 69% of cases to ensure the free gastroduodenal passage and at 31% was necessary the combined operation.
