Surgical treatment for mucin-producing tumors of the pancreas.
OBJECTIVE
Our objectives in this study were to evaluate the surgical treatment for mucin-producing tumor of the pancreas from the clinicopathological and imaging features.


METHODS
Thirty-one patients with mucin-producing tumor of the pancreas were examined based on clinicopathological analyses to determine the appropriate surgical treatment.


RESULTS
The clinical and imaging features easily distinguished the main duct type of intraductal papillary lesions (type Ia), branch type of intraductal papillary lesions (type Ib) and mucinous cystic neoplasms (type II). From pathological examinations, a dilated main pancreatic duct had the malignant potentiality and multicentric development.


CONCLUSIONS
Pancreatic segments containing a dilated main pancreatic duct should be resected in type Ia. Type Ib is sufficient for partial resection without lymphadenectomy. Type II also requires partial resection of the cystic neoplasm. A standard lymphadenectomy may be an option when type Ia and II show invasive features.
