Background: In cases of difficult bile duct cannulation, the use of wire-guided cannulation over a pancreatic stent (WGC-PS) or the double guidewire technique (DGT) may facilitate biliary cannulation. The aim of this study was to compare the outcomes of WGC-PS and DGT in patients with difficult biliary cannulation.
Methods: We conducted a retrospective cohort study of all endoscopic retrograde cholangiopancreatographies (ERCPs) performed between July 2009 and November 2014 at a single tertiary referral center.
Testosterone replacement and bone mineral density in male pituitary tumor patients.

Article Synopsis
- Hypopituitarism is linked to osteoporosis and osteopenia, particularly when hypogonadotropic hypogonadism is involved, but the impact of testosterone replacement therapy (TRT) on bone mineral density (BMD) in these patients post-surgery has not been studied in Korea.
- A retrospective study involving 21 male patients who underwent pituitary tumor surgery showed that TRT led to a significant increase in serum testosterone and an improvement in lumbar spine BMD over an average follow-up of 56 months, although no changes were observed in femur neck or total femur BMD.
- The findings suggest that TRT can positively influence lumbar spine BMD in post-surgical hypogonadal patients with pit
