Q: Answer this question A: The question asks: As per the current international guidelines SENDAI, the threshold of diameter of the main pancreatic duct for diagnosing Intraductal Papillary Mucinous Neoplasm IPMN is: The answer is 5 mm. The Sendai/Fukuoka consensus guidelines define Main Duct IPMN MD-IPMN as dilation of the main pancreatic duct MPD to ≥5 mm in the absence of other causes of obstruction. A pancreatic cyst 5 mm that communicates with the MPD is classified as Branch Duct IPMN BD-IPMN. From the Fukuoka consensus which updated the original Sendai guidelines, the threshold was lowered to ≥5 mm MPD diameter as the cutoff for defining/concerning for MD-IPMN involvement. The older Sendai criteria used ≥10 mm or features like the "fish-mouth" papilla with mucin extrusion. Correct answer: 5 mm The options shown 8 mm, 5 mm, 3 mm, 10 mm confirm 5 mm is the correct choice per the Sendai/Fukuoka international consensus guidelines for diagnosing IPMN with main pancreatic duct involvement.
