Interactive Decision Tree
Algorithm Steps
- ▶Start
Pancreatic Cyst Identified
Incidental or symptomatic finding
- ●Action
Cyst Characterization
MRI/MRCP, consider EUS
- Size, location, duct communication
- Main duct dilation?
- Solid component/nodule?
- ◆Decision
IPMN Type
- Main Duct (MD-IPMN): MPD ≥5mm
- Branch Duct (BD-IPMN): cyst communicates with duct
- Mixed type
- ●Action
Main Duct IPMN
Higher malignancy risk
- ◆Decision
High-Risk Stigmata (Fukuoka)
- Enhancing solid component ≥5mm
- MPD ≥10mm
- Obstructive jaundice with cystic lesion
- ●Action
Surgical Resection
If fit for surgery
- MD-IPMN with HRS: resect
- BD-IPMN with HRS: resect
- Oncologic resection (Whipple, distal)
- ■End
Follow-up Plan
Surveillance or post-op monitoring
- ◆Decision
Worrisome Features
- Cyst ≥3cm
- Enhancing mural nodule <5mm
- Thickened/enhancing walls
- MPD 5-9mm
- Lymphadenopathy
- Elevated CA 19-9
- Cyst growth ≥5mm/2yr
- ●Action
EUS-FNA
Further characterization
- CEA, amylase, cytology
- Molecular markers if available
- Guides surgery vs surveillance
- ●Action
Surveillance
Based on size and features
- <1cm: MRI q2-3y
- 1-2cm: MRI yearly
- 2-3cm: EUS q6-12mo, MRI yearly
- >3cm: close surveillance, consider EUS-FNA
- ●Action
Branch Duct IPMN
Risk stratify by features
Guideline Source
AGA Clinical Practice Update on Pancreatic Cysts
Clinical Safety Information
Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Fukuoka guidelines for resection, AGA for surveillance
- Main duct IPMN higher risk than branch duct
- EUS-FNA helps but doesn't replace clinical judgment
- Patient factors (age, comorbidities) affect decision
Applicable Regions
EU: European consensus on pancreatic cysts
US: AGA 2023 update + Fukuoka 2017
