A 72 year old patient was admitted to our department with progressive
abdominal symptoms caused by chronic pancreatitis. Physical examinatio
n and laboratory data were unremarkable, ultrasound showed a cystic le
sion beneath the pancreatic head. Initial endoscopic examination demon
strated a duodenal stenosis; in the second examination the stenosis ha
d resolved by spontaneous perforation of the pseudocyst into the duode
nal bulb. Pancreatic and peri-pancreatic pseudocysts are common in. ac
ute and chronic pancreatitis; the frequency of their diagnosis increas
ed following the advent of ultrasonography and computed tomography as
diagnostic tools and more intensive clinical monitoring. Our knowledge
about the incidental course of the disease is still limited. When the
diagnosis is established, a lot of questions referring to the choice
of therapeutic regime conservative treatment percutaneous intervention
, endoscopic or surgical procedures arise. Therapeutic possibilities a
nd their advantages are discussed.
