COMPLETE resection of a pancreatic cyst, although the procedure of choice, is often technically difficult or impossible to perform, so that an alternative operation such as external or internal drainage of the cyst becomes necessary. Drainage operations, whether of the internal or external type, are contraindicated in the treatment of multilocular tumors of the pancreas such as cystadenomas, cystadenocarcinomas or dysontogenetic cysts. Complete resection of these tumors offers the only possibility of a cure. Unilocular cysts such as the retention and pseudocysts of the pancreas are suitable for internal or external drainage.
External drainage, or so-called marsupialization, of pancreatic cysts, which was first carried out by Gussenbauer1 in 1882, remains today the most frequently performed operation for these cysts. Internal drainage may be accomplished either by inserting multiple drains into the cyst cavity or by suturing the edge of the opening in the cyst wall to the cut edge
