概要 Introduction:In patients with surgically altered
anatomy(SAA), pancreatic diseases are treated with
balloon enteroscopy(BE)-assisted ERCP or endoscopic
ultrasound(I-EUS), but these procedures involve
technical challenges. BE-ERCP:BE-ERCP is
challenging due to difficulty in target access, reduced
maneuverability, and limited devices. Scope insertion
should align with reconstruction type, employing
over-tube adjustments, abdominal compression, and
scope manipulation techniques for severe adhesions.
Gel immersion and image-enhanced endoscopy aid
pancreatic duct(PD)orifice identification. Optimizing
scope configuration and papilla orientation improves
cannulation. Novel devices and techniques enable effective
PD cannulation, pancreatojejunostomy stenosis(
PJS)dilation, and management of proximally migrated
stents, among other interventions. I-EUS:
EUS-guided pancreatic drainage is a viable alternative
when BE-ERCP is unfeasible in SAA but remains
technically challenging due to narrow ducts, stenosis,
and stent management. Low Echo Reduction mode
enhances PD visualization, improving puncture accuracy.
A two-step puncture facilitates PD access;contrast
injection for PD expansion followed by optimized
repuncture. For completely obstructed PJS, a
guidewire stiff-tip puncture serves as a rescue approach
for recanalization. As EUS-PD often requires
re-intervention, appropriate and effective stent removal
techniques have been developed. Conclusion:
Troubleshooting strategies for pancreatic diseases in
SAA enhance success and reduce complications, warranting
further validation.
