METHOD OF ENDOSCOPIC TREATMENTS FESTER PANCREATIC PSEUDOCYSTS Russian patent published in 2009 - IPC A61B17/94 

FIELD: medicine.

SUBSTANCE: endoscope is introduced into superior gastrointestinal tract. Posterior wall of stomach or duodenum is burned with a needle-knife papillotome within greatest bulging of pseudocyst into lumen thereof. After posterior wall of stomach or duodenum is burned with a needle-knife papillotome, a stent 10 or 11 Fr is brought in the formed fistula. Then, at the distance 2-3 cm from the first fistula, a needle-knife papillotome forms the second even fistula. Through the second fistula, polyvinyl chloride pig-tail probe is inserted into the cyst cavity. One end of the probe is left in the cavity of fester pseudocyst. The other end of the probe is delivered through nose. The pig-tail probe is removed after reduction of inflammation, while the stent 10 or 11 Fr is removed from the pseudocyst cavity 3 months later.

EFFECT: possibility to deliver antiseptic solutions and antibiotics directly into purulent cavity, to generate internal fistula on the stent to provide physiology of diversion of pancreatic juice in gastrointestinal lumen, to reduce risk of haemorrhage, to ensure minimal invasiveness of surgical interventions and appropriate drainage.
