[Endoscopic drainage of postnecrotic pancreatic cysts].

Results of endoscopic drainage of postnecrotic pancreatic cysts in 12 patients were analyzed. Possibilities of the method are limited by location of the cysts in pancreatic head and corpus. Clear visualization of the cysts on the gastric or duodenal wall is the main condition for this procedures feasibility. Surgery must be started with point burning in the wall that is safe and permits the surgeon to stop procedure when cyst is not found. When the cyst is drained through the duodenal lumen, it is necessary to visualize Veter's papilla and perform the procedure below it to prevent lesion of a distal part of the common bile duct. Section of the cyst with wall thickness to 3-4 mm from the duodenal lumen and the ikness to 6-7 mm from the stomach is safe enough. Endoscopic procedures are not indicated in hypertension in the bile ducts.
