Background/aims: Endoscopic papillary balloon dilation has been accepted as a less hazardous alternative to endoscopic sphincterotomy for removal of bile duct stones in patients with impaired hemostasis. Several manometric studies have suggested that endoscopic papillary balloon dilation can be expected to preserve papillary function. However, the aspect of the preservation of postprandial relaxation has not been addressed.
Methodology: Seven, 7 and 6 patients underwent fatty-meal magnetic resonance cholangiography before endoscopic papillary balloon dilation for the treatment of common bile duct stones, and then 12 and 24 months after the procedure. Seven patients were employed as controls. Magnetic resonance cholangiography images were obtained on a 1.5-Tesla scanner (Signa Horizon, GE Medical Systems, Milwaukee, WI) with a phased-array torso coil. After an overnight fast, magnetic resonance cholangiography was performed before and after fatty-meal ingestion.
Results: No patients showed significant postprandial increase of the bile duct diameter except one patient with stone impaction during the examination.
Conclusions: Endoscopic papillary balloon dilation may preserve the papillary function of postprandial relaxation.

Background: Rathke cleft cysts (RCCs) are benign sellar/suprasellar lesions that result from mucin-secreting vestigial remnants within the pars intermedia of the pituitary gland. When symptomatic, they can present with retro-orbital headaches, visual field defects, and/or pituitary dysfunction.
Observations: A 35-year-old female presented with subacute retro-orbital headache, right ptosis, and blurred vision.

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a severe and deadly adverse event following ERCP. The ideal method for predicting PEP risk before ERCP has yet to be identified. We aimed to establish a simple PEP risk score model (SuPER model: Support for PEP Reduction) that can be applied before ERCP.

Background: Pancreatic cancer remains one of the most lethal malignancies worldwide, with a poor prognosis often attributed to late diagnosis. Understanding the correlation between pathological type and imaging features is crucial for early detection and appropriate treatment planning.
Aim: To retrospectively analyze the relationship between different pathological types of pancreatic cancer and their corresponding imaging features.

Gallbladder carcinoma (GBC) is the most common malignant tumor of biliary tract, with poor prognosis due to its aggressive nature and limited therapeutic options. Early detection of GBC is a major challenge, with most GBCs being detected accidentally during cholecystectomy procedures for gallbladder stones. This letter comments on the recent article by Deqing in the , which summarized the various current methods used in early diagnosis of GBC, including endoscopic ultrasound (EUS) examination of the gallbladder for high-risk GBC patients, and the use of EUS-guided elastography, contrast-enhanced EUS, trans-papillary biopsy, natural orifice transluminal endoscopic surgery, magnifying endoscopy, choledochoscopy, and confocal laser endomicroscopy when necessary for early diagnosis of GBC.
