[Mucinous cystadenoma of the pancreas--exact endoscopic assessment with pancreoscopy].

Mucinous cystadenomas of the pancreas are rare tumors of the exocrine pancreas with a well-documented risk for malignant degeneration. We present 2 patients with this cystic pancreatic neoplasia who were admitted with signs of obstructive pancreatitis. The exact diagnosis was found preoperatively by a new endoscopic technique: mother-baby duodenoscopy. The small-caliber endoscopy allows the precise description of intraductal tumors. Histological resp. cytological specimens obtained under direct optical control, allow for an exact pathoanatomical classification. This modern endoscopic system is an important addition for diagnosing intraluminal tumors of the hepato-biliary system.
