Flexible endoscopy assisted by Ligasure™ for treatment of Zenker's diverticulum: an effective and safe procedure.

Background: Flexible endoscopy allows use of the vessel-tissue sealer Ligasure™ (Covidien, Massachusetts, USA) to perform diverticulotomy. Few studies have used this endoscopic approach in the uncommon disorder Zenker's diverticulum. The aim of the present study was to evaluate the effectiveness and safety of flexible endoscopy treatment assisted by Ligasure™.

Short- and long-term clinical outcomes of self-expandable metal stents inserted for colorectal obstruction and efficacy of different insertion techniques.

Objectives: (1) To evaluate the short- and long-term clinical outcomes of patients after colorectal stent placement and (2) to assess the safety and efficacy of the stents for the resolution of colorectal obstruction according to the insertion technique.

Methods: Retrospective cohort study which included 177 patients with colonic obstruction who underwent insertion of a stent.

Results: A total of 196 stents were implanted in 177 patients.

Accuracy of the Ultra-Rapid Urease Test for diagnosis of Helicobacter pylori infection.

Background: Rapid Urease Test (RUT) is a simple, cheap and relatively fast method for diagnosing Helicobacter pylori infection. It is therefore the preferred method used for patients undergoing gastroscopy. Most kits require 24h to give results.

Randomised clinical trial comparing sequential and concomitant therapies for Helicobacter pylori eradication in routine clinical practice.

Objectives: No trial has compared non-bismuth quadruple 'sequential' and 'concomitant' regimens in settings with increasing clarithromycin rates. The study aims to compare the effectiveness and safety of these therapies for Helicobacter pylori treatment.

Design: Prospective randomised clinical trial in 11 Spanish hospitals.
