INTRODUCTION Endoscopic submucosal dissection (ESD) has become the treatment of choice for early gastric malignancies. In recent years, the ESD technique has been implemented in Western countries with increasing use. OBJECTIVES To describe the results of gastric ESD in a Western country with a low incidence of gastric cancer. PATIENTS AND METHODS The prospective national registry was conducted over 4 years in 23 hospitals, including 30 endoscopists. Epithelial and subepithelial lesions (SEL) qua...

Missed adenomas are the main concern for endoscopists. Right colon retroflexion (RCR) seems to increase the adenoma detection rate (ADR), but important variation in success and usefulness of this maneuver has been reported in the literature Primary objective: to assess additional adenoma detection rate (AADR) detected during the RCR attempt. Secondary objectives: to assess success rates of RCR, variables associated with it, and safety of RCR. This is a prospective, unicentric, non-randomized stu...

Introduction Delayed bleeding (DB) is the most common major complication of endoscopic mucosal resection (EMR). Two randomized clinical trials recently demonstrated that clip closure after EMR of large nonpedunculated colorectal polyps (LNPCPs) reduces the risk of DB. We analyzed the cost-effectiveness of this prophylactic measure. Methods EMRs of LNCPCPs were consecutively registered in the ongoing prospective multicenter database of the Spanish EMR Group from May 2013 until July 2017. Patients...

BACKGROUND The most important predictor of unsuccessful bowel preparation is previous failure. For those patients with previous failure, we hypothesized that a nurse-led educational intervention by telephone shortly before the colonoscopy appointment could improve cleansing efficacy. METHODS We performed a multicenter, endoscopist-blinded, randomized controlled trial. Consecutive outpatients with previous inadequate bowel preparation were enrolled. Both groups received the same standard bowel pr...

The present evidence-based guidelines are focused on the use of device-assisted enteroscopy in the management of small-bowel diseases. A panel of experts selected by the Spanish and Portuguese small bowel study groups reviewed the available evidence focusing on the main indications of this technique, its role in the management algorithm of each indication and on its diagnostic and therapeutic yields. A set of recommendations were issued accordingly.
