Low risk of new dysplastic lesions in an inflammatory bowel disease population study with dye chromoendoscopy.

Rates of new dysplastic lesions or cancer progression after first dye chromoendoscopy in the era of high-definition endoscopy have yet to be determined.  A multicenter, population-based, retrospective cohort study was performed in seven hospitals in Spain. Patients with inflammatory bowel disease and fully resected (R0) dysplastic colon lesions under surveillance with high-definition dye-based chromoendoscopy were sequentially enrolled between February 2011 and June 2017, with a minimum endoscopic follow-up of 36 months.

Endoscopic ultrasound versus multidetector computed tomography in preoperative gastric cancer staging.

Introduction: Endoscopic ultrasonography (EUS) is the gold standard technique in loco-regional staging of gastric adenocarcinoma (GAC). Nevertheless, the introduction of multidetector-row computed tomography (MDCT) allows accurate studies to be performed.

Objective: To compare the diagnostic yield of EUS and MDCT in loco-regional preoperative staging of gastric adenocarcinoma.

The Endoscopic Reference Score shows modest accuracy to predict either clinical or histological activity in adult patients with eosinophilic oesophagitis.

Background: Conflicting results have been recently reported for the accuracy of the Endoscopic Reference Score (EREFS), an standardised endoscopic classification, to predict the histological activity of eosinophilic oesophagitis (EoE).

Aim: To evaluate the accuracy of the EREFS to predict either histological or clinical activity of EoE.

Methods: Prospective multicentre study conducted in eight Spanish centres evaluating adult EoE patients, either naïve or after treatment.

The utility of faecal calprotectin to predict post-operative recurrence in Crohńs disease.

Objective: Endoscopic recurrence in Crohńs disease occurs in up to 80% of patients during the first year after surgery. Due to this, these patients need close monitoring. Faecal calprotectin has been proposed to be used as a non-invasive marker to monitor inflammatory activity.
