In severe acute pancreatitis, the drainage of activated pancreatic enzymes,
infectious substances and necrotic tissue from the abdominal cavity is cri
tical, especially after the operation. We use Faycon drainage tubes togethe
r with multi-use feeding tubes. Just after the operation, normal saline is
added through the feeding tube and the Faycon drainage tube is auctioned co
ntinuously. Irrigation is necessary for more than two weeks.
