[Transcutaneous drainage of pancreatic pseudocysts]

The clinical study includes 76 pancreatic pseudocysts localized in the head (24), body (37), and tail (15). The effect of treatment by means of a single or repeated purposeful aspiration in ultrasonic control is discussed. Recovery occurred in 83.3% of cases with cysts measuring up to 5 cm, in 61.3% in those with cysts measuring from 5 to 10 cm, and in 11.1% of cases in which the cysts measured more than 10 cm. As the result of 15 draining manipulations of cysts which were irresponsive to aspiration (9 of them measuring from 5 to 10 cm and 6 larger than 10 cm) complete recovery occurred in 13 cases. The authors discuss the indications for single, two, and many punctures on basis of a complex appraisal of the gland, the size and type of the cyst, and the cytologic results. The indications for percutaneous drainage, the period and techniques of its performance and preliminary and postmanipulation treatment with drugs are determined and the occurring complications are shown.
