Randomized Controlled Trial Comparative Study
Endoscopic cyanoacrylate injection versus beta-blocker for secondary prophylaxis of gastric variceal bleed: a randomised controlled trial.
Bleeding from gastric varices is often severe and difficult to manage. Endoscopic injection of gastric varices with cyanoacrylate is effective in prevention of rebleeding. The efficacy of beta-blockers in secondary prophylaxis of gastric variceal bleed has not been well studied. A comparison of the efficacy of beta-blocker treatment and cyanoacrylate injection for the prevention of gastric variceal rebleeding was carried out. ⋯ Cyanoacrylate injection is more effective than beta-blocker treatment for the prevention of gastric variceal rebleeding and improving survival.

Transient receptor potential vanilloid type 1 (TRPV1) has been shown to play an important role in visceral hypersensitivity. A significant proportion of patients with inflammatory bowel disease (IBD) continue to complain of abdominal pain despite their disease being otherwise quiescent. We investigated TRPV1-immunoreactive fibres in rectosigmoid biopsies taken from such patients with correlation to abdominal pain severity. ⋯ Increased TRPV1 nerve fibres are seen in quiescent IBD with IBS-like symptoms together with a correlation to pain severity. TRPV1 may contribute to the pathophysiology of ongoing pain and visceral hypersensitivity in this group of patients, providing a potential therapeutic target.
