Reliability and accuracy of a novel classification system using peroral cholangioscopy for the diagnosis of bile duct lesions.

Background: The aim of this study was to propose a novel, comprehensive, macroscopic classification for bile duct lesions.

Methods: A two-stage protocol was designed. In Stage I, a retrospective study (September 2013 to September 2015) of patients with bile duct lesions detected by peroral cholangioscopy (POCS) was performed.

Clinical impact of confocal laser endomicroscopy in the management of gastrointestinal lesions with an uncertain diagnosis.

Aim: To evaluate the clinical impact of confocal laser endomicroscopy (CLE) in the diagnosis and management of patients with an uncertain diagnosis.

Methods: A retrospective chart review was performed. Patients who underwent CLE between November 2013 and October 2015 and exhibited a poor correlation between endoscopic and histological findings were included.

Multiple Intestinal Erosions as a Result of Hemorrhage due to Parasites: Case Reports and Review of the Literature.

Obscure gastrointestinal bleeding appears to be uncommon in patients with parasites. In spite of that some reports had described this relationship in patients evaluated during capsule endoscopy procedures; the characteristic of the bleeding lesions remains unclear. This paper describes two patients with a massive obscure gastrointestinal bleeding due to ascariasis, using the new capsule endoscopy technology "MiroCam", describing the characteristic of the lesions found in our patients (observed in a better image quality), and reviewing the literature.

Endoscopic chemotherapy with 5-fluorouracil in advanced gastric cancer.

Introduction: It has been reported that a local injection of 5-fluorouracil (5-FU) administered endoscopically can have a favorable result in patients with early gastric cancer.

Methods: We report the application of a local injection of 5-FU administered endoscopically in three patients with advanced gastric cancer (AGC) who refused or were not suitable for surgery or systemic chemotherapy. The benefits of locally applied endoscopic chemotherapy (EC) with 5-FU as an alternative therapy were evaluated.

Is a 7-day Helicobater pylori treatment enough for eradication and inactivation of gastric inflammatory activity?

Aim: To compare the efficacy of a 7-d vs 10-d triple therapy regarding H pylori eradication, endoscopic findings and histological gastric inflammatory inactivation in the Ecuadorian population.

Methods: 136 patients with dyspepsia and H pylori infection were randomized in 2 groups (68 per group): group 1, 7-d therapy; group 2, 10-d therapy. Both groups received the same medication and daily dosage: omeprazole 20 mg bid, clarithromycin 500 mg bid and amoxicillin 1 g bid.
