main pancreatic duct by duodenoscopic examination was reported. Because of the low
malignant potential of such lesions, duodenum-preserving resection of the head of the pancreas
was performed, and the intra-operative histological examination showed no malig-nancy of the
resected pancreatic head and no other surgical procedures, such as lymph-adenectomy nor
pancreato-duodenectomy were necessary. The significance of this case report lies in that a less
invasive operation should be selected at first to diagnose whether the lesion is malignant or not,
and als0 that the selected operation itself must be sufficient to resect an adequate part of the
pancreatic tissue involving the cystic lesion, ifnot malignant. Here, we report the process to select
the procedure and the surgical technique.</p>
