Randomized Controlled TrialAdding triamcinolone to endoscopic ultrasound-guided celiac plexus blockade does not reduce pain in patients with chronic pancreatitis.
The efficacy of endoscopic ultrasound-guided celiac plexus blockade (EUS-CPB) for painful chronic pancreatitis (CP) is uncertain. Triamcinolone is often mixed with bupivacaine to lengthen the analgesic effect. We investigated whether addition of triamcinolone increases and lengthens pain relief compared with EUS-CPB with only bupivacaine. ⋯ Triamcinolone does not increase pain relief or lengthen the effects of EUS-CPB.

Histologic and imaging features of mural nodules in mucinous pancreatic cysts.
Mural nodules predict malignancy within pancreatic cysts, but it is not clear whether endoscopic ultrasound (EUS) and computed tomography (CT) accurately identify nodules. We assessed images and the histology of mural nodules in branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) and mucinous cystic neoplasms (MCNs) and identified criteria to distinguish mural nodules from mucus. ⋯ Malignancy is associated with epithelial nodules in BD-IPMNs and MCNs, but most echogenic lesions detected in cysts by EUS are mucus. Knowledge of features that discriminate mucus from mural nodules improves the diagnostic accuracy of EUS.
