  2. Willing to comply with the study procedures described in the protocol.
  3. Willing and able to give written informed consent.
  4. Meet at least one of the following three criteria in relation to the diagnosis or prognosis of IPMN:

    4.1 Diagnosis of IMPN based on evidence of major criteria or existence of at least 2 minor criteria. Major criterion: Typical findings on MRI and/or EUS (single or multiple cysts with clear ductal communication and/or focal or diffuse dilatation # 5 mm in diameter of the main pancreatic duct without apparent obstructive cause). Minor criteria: a) Mucosecretory cells and/or extracellular mucin on cytological examination of intracystic fluid. b) Clear mucoid or filmy appearance of the intracystic fluid. c) Intracystic fluid CEA concentration >192 ng/mL or intracystic glucose < 50 mg/dL.

    4.2 IPMN with cysts with a diameter # 10 mm and/or focal or diffuse dilatation of the main pancreatic duct with a diameter # 7 mm requiring EUS-FNA for diagnostic purposes or to assess risk or existence of malignancy following the main clinical practice guidelines.

    4.3 IPMN with indication for surgical resection of the lesion.

  5. In case of a woman of childbearing age*, willing to use highly effective contraception or practice sexual abstinence from the screening visit until one week after undergoing the procedure under study. Highly effective contraceptive methods will include: combined oral, intravaginal or transdermal hormonal contraceptives (containing oestrogens and progestogens) associated with ovulation inhibition; oral, injectable or implantable progestogen-only hormonal contraception associated with ovulation inhibition; intrauterine device; intrauterine hormone-releasing system; bilateral tubal occlusion; vasectomised partner; and sexual abstinence. 6. If you are a woman of childbearing age, be willing to undergo a urine pregnancy test prior to inclusion in the study.

Exclusion Criteria:
