Background and objectives: There are few scales with prospective validation forthe assessment

of the upper gastrointestinal mucosal cleanliness during an esophagogastroduodenoscopy (EGD).

The aim of this study was to develop a valid and reproducible cleanliness scale for use during

an EGD.

Methods: We developed a cleanliness scale (Barcelona scale) with a score (0---2 points) of five

segments of the upper gastrointestinal tract with thorough cleaning techniques (esophagus,

fundus, body, antrum, and duodenum). First, 125 photos (25 of each area) were assessed, and a

score was assigned to each image by consensus among 7 experts endoscopists. Subsequently, 100

of the 125 images were selected and the inter- and intra-observer variability of 15 previously

trained endoscopists was evaluated using the same images at two different times.

Results: In total, 1500 assessments were performed. In 1336/1500 observations (89%) there

was agreement with the consensus score, with a mean kappa value of 0.83 (0.45---0.96). In the

second evaluation, in 1330/1500 observations (89%) there was agreement with the consensus

score, with a mean kappa value of 0.82 (0.45---0.93). The intra-observer variability was 0.89

(0.76---0.99).

Conclusions: The Barcelona cleanliness scale is a valid measure and reproducible with minimal

training. Its application in clinical practice is a significant step to standardize the quality of the

EGD.

Endoscopic ultrasound-guidedfine-needle aspirationof portal vein thrombosis in patients with chronic liverdisease and suspicion of hepatocellular carcinomaAntonio Z. Gimeno Garciaa, Jose R. Apariciob, Angel Barturenc, Miguel Morenoa, David Nicolas-PerezaandEnrique QuinteroaBackgroundDifferentiation between benign and malignant portal vein thrombosis (PVT) in the setting of a hepatocellularcarcinoma (HCC) is of paramount importance. Histological analysis is usually not carried out because of potential severe sideeffects of the percutaneous approach. Endoscopic ultrasound-guidedfine-needle aspiration (EUS-FNA) may be safer and mayguide the clinical management of patients with HCC.ObjectiveTo describe the feasibility of the EUS-FNA in a series of patients with HCC and PVT.Materials and methodsA chart review of patients with PVT was performed from 2014 to 2016 in three tertiary care hospitals ofSpain. Patients with chronic liver disease and PVT with a suspicion of HCC referred for EUS-FNA were included. The impact ofthe EUS-FNA was assessed by comparing staging following the Barcelona Clinic Liver Cancer algorithm (BCLC) before and afterEUS-FNA.ResultsOf 104 patients with PVT and chronic liver disease, 23 were considered candidates for EUS-FNA. Eight patients werereferred for EUS-FNA. The technique was feasible in seven patients and FNA was positive in six patients. No side effects werereported. EUS-FNA upstaged six out of seven (85.7%) patients: one patient BCLC stage B, two patients BCLC stage A, andthree patients in whom the HCC was not diagnosed before EUS-FNA of the PVT. A benign PVT was found in the explant of theonly patient with a negative PVT.ConclusionEUS-FNA is a valuable technique in selected patients with chronic liver disease with PVT. It is feasible, safe, andmay alter the clinical management in these patients. Eur J Gastroenterol Hepatol 00:000–000Copyright © 2018 Wolters Kluwer Health, Inc. All rights reserved.
