Simplified magnetic anchor-guided endoscopic submucosal dissection: an ex vivo porcine model.

Introduction And Aims: Endoscopic submucosal dissection (ESD) is a well-established treatment for superficial gastrointestinal tumors and enables en bloc resection. Adequate tissue tension is important for safe and effective dissection. Simplified magnetic anchor-guided ESD (MAG-ESD) with a neodymium magnet has potential benefits, compared with other current traction methods.

[p53 expression in the gastric mucosa of patients infected with Helicobacter pylori].

Background: Helicobacter pylori (Hp) is recognized as a type 1 carcinogen for gastric cancer associated with pre-neoplastic lesions (atrophy and intestinal metaplasia [IM]). Its relation with p53, which intervenes in the cell cycle, has had contradictory results.

Aims: To analyze p53 expression in gastric mucosa and its relation with Hp infection.
