[Postnecrotic cysts of the pancreas: possible ways of minimally invasive external and internal drainage].

The authors have shown a possibility of minimally invasive interventional surgery in treatment of postnecrotic cysts of the pancreas and their complications. The most optimal accesses for drainage of the cavities located inside the body and the pancreas head are determined. The use of the methods of internal drainage of the cyst cavity connected with the main pancreatic duct allowed avoidance of open operations. The results of antegrade percutaneous or transcavital as well as retrograde endoscopic restoration of the patency of the main pancreatic duct in treatment of the pancreatic cysts connected with the duct system are shown.
