A 65-year-old man suffering from acute pancreatitis underwent MRI scanning, which revealed a low signal on the T1 and T2 sequences, and hypovascularity in arterial phase in the head of the pancreas. This corresponded to the area showing the absence of the lower common bile duct. FDG-PET was highly suggestive of pancreatic cancer (T4N1M0, Stage IVa) with lymph node metastasis. He was treated with systemic chemotherapy using gemcitabine (GEM) followed by radiotherapy. His symptoms gradually improved with a reduction in size of the primary lesion. The patient has been receiving systemic chemotherapy using S-1 without recurrence.

AMP-activated protein kinase (AMPK) is the master regulator of cellular energy which gets activated during energy stress and restores tissue homeostasis. AMPK is widely expressed in the pancreas and is involved in protein synthesis. In cerulein-induced acute pancreatitis (AP), diminished AMPK activity in the pancreatic tissue may be associated with pancreatic inflammation and oxidative stress.

Objectives: This study aimed to investigate the diagnostic performance and safety of endoscopic ultrasound-guided tissue acquisition (EUS-TA) for perivascular soft-tissue cuffing (PSTC).
Methods: This single-center, retrospective study evaluated patients in whom EUS-TA was performed for PSTC in pancreatic or bile duct cancer lesions between October 2017 and March 2024. PSTC was defined as a perivascular soft-tissue area contiguous with nearby blood vessels from the suspected primary tumor.
