New Generation Express View: An Artificial Intelligence Software Effectively Reduces Capsule Endoscopy Reading Times.

BACKGROUND: Reading capsule endoscopy (CE) is time-consuming. The Express View (EV) (IntroMedic, Seoul, Korea) software was designed to shorten CE video reading. Our primary aim was to evaluate the diagnostic accuracy of EV in detecting significant small-bowel (SB) lesions.

Biliary Tree Diagnostics: Advances in Endoscopic Imaging and Tissue Sampling.

The diagnostic approach to the biliary tree disorders can be challenging, especially for biliary strictures. Albeit the great diagnostic impact of endoscopic retrograde cholangiopancreatography (ERCP) which allows one to obtain fluoroscopic imaging and tissue sampling through brush cytology and/or forceps biopsy, a considerable proportion of cases remain indeterminate, leading to the risk of under/over treated patients. In the last two decades, several endoscopic techniques have been introduced in clinical practice, shrinking cases of uncertainties and improving diagnostic accuracy.

Bisacodyl plus split 2-L polyethylene glycol-citrate-simethicone improves quality of bowel preparation before screening colonoscopy.

Aim: To compare the bowel cleansing efficacy, tolerability and acceptability of split 2-L polyethylene glycol (PEG)-citrate-simethicone (PEG-CS) plus bisacodyl (BIS) vs 4-L PEG for fecal occult blood test-positive screening colonoscopy.

Methods: This was a randomised, observer-blind comparative study. Two hundred and sixty-four subjects underwent screening colonoscopy (mean age 62.

Prevalence of different subtypes of serrated polyps and risk of synchronous advanced colorectal neoplasia in average-risk population undergoing first-time colonoscopy.

Objectives: A growing body of evidence indicates that patients with sessile serrated adenoma/polyp (SSA/P) and traditional serrated adenoma (TSA) are at risk for subsequent malignancy. Despite increasing knowledge on histological categorization of serrated polyps (SPs) data are lacking on the actual prevalence and the association of each SP subtype with advanced colorectal neoplasia.

Methods: We prospectively determined the prevalence of different SP subtypes and evaluate the association with synchronous advanced neoplasia in asymptomatic average-risk subjects undergoing first-time colonoscopy.

Barrett's esophagus and adenocarcinoma risk: the experience of the North-Eastern Italian Registry (EBRA).

Objective: To establish the incidence and risk factors for progression to high-grade intraepithelial neoplasia (HG-IEN) or Barrett's esophageal adenocarcinoma (BAc) in a prospective cohort of patients with esophageal intestinal metaplasia [(BE)].

Background: BE is associated with an increased risk of BAc unless cases are detected early by surveillance. No consistent data are available on the prevalence of BE-related cancer, the ideal surveillance schedule, or the risk factors for cancer.

A randomized controlled trial evaluating a new 2-L PEG solution plus ascorbic acid vs 4-L PEG for bowel cleansing prior to colonoscopy.

Background: Bowel preparation is critical for the efficacy and safety of colonoscopy. Poor patient tolerance to bowel preparation has been associated with the high amount of fluid administered. A 2-L polyethylene glycol (PEG) solution containing ascorbic acid has been recently developed.

Small bowel exploration by wireless capsule endoscopy: results from 314 procedures.

Objectives: To assess the diagnostic efficiency of capsule endoscopy in a large group of patients with different indications, to weigh the reliability of the procedure for excluding small bowel lesions, and to identify factors associated with the likelihood of obtaining a definitive diagnosis.

Methods: Three hundred four consecutive patients (141 female, mean age 55 years, range 12-91 years) underwent capsule endoscopy in two different Gastroenterology Units, for a total of 314 procedures, and were followed-up for a median period of 15 months. Referrals were obscure occult/overt gastrointestinal bleeding (203 patients), suspected small bowel disease (74), gastrointestinal polyposis (18), suspected/previous intestinal or endocrine malignancies (13), previously diagnosed intestinal lymphangectasia (3), and vascular abnormalities (3).
