Self expandable metal stents for anastomotic stricture following liver transplant.

Background: Endoscopic treatment for biliary strictures with plastic stent placement has been used widely. The use of covered self-expandable metal stents (CSEMS) has been reported in anastomotic strictures post liver transplant. The aim of this study was to evaluate the efficacy of different CSEMS in these subjects.

Safety and efficacy of radiofrequency ablation in the management of unresectable bile duct and pancreatic cancer: a novel palliation technique.

Unlabelled: Objectives. Radiofrequency ablation (RFA) has replaced photodynamic therapy for premalignant and malignant lesions of the esophagus. However, there is limited experience in the bile duct.

[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.

Self-expanding metal stents versus antrectomy for the palliative treatment of obstructive adenocarcinoma of the gastric antrum.

Background: gastric cancer patients are first diagnosed with an unresectable tumor in up to 40% of cases. Gastric outlet obstruction causes nausea, vomiting, dehydration and malnutrition. The aim of the study was to compare self-expanding metal stents to antrectomy and Roux-en Y gastrojejunostomy for palliation of obstructive adenocarcinoma of the gastric antrum.
