EUS-FNA was accurate in the evaluation of suspected pancreatic malignancy regardless of its size, location, or size of needles. It was useful also in the confirmation of small pancreatic malignancies less than 10mm.

EUS-FNA for pancreatic cancer did not significantly increase the risk of peritoneal carcinomatosis.

A mural nodule of 10 mm is appropriate as an indicator of surgery in the follow-up of branch duct IPMN.

More improvement in disorders of nitrogen metabolism in liver cirrhosis occurred after administration of BCAA with zinc than after BCAA alone over 5-6 months of treatment. Further investigation is necessary to determine mechanisms of the action and longer-term clinical efficacy.

Main duct IPMN with a lower likelihood of malignancy was divided into 2 subgroups: neoplasm that progressed and that which did not progress during its natural course. The former should be resected considering its malignant potential, whereas the latter may be managed nonsurgically as long as it stays unchanged.
