Endoscopic submucosal dissection: a country dissemination experience and outcomes.

Objective: An increasing use of endoscopic submucosal dissection (ESD) has been reported in Western countries, although some differences in training schemes and outcomes have been described. We aimed to report the training model, implementation, and outcomes of ESD in Portugal.

Methods: All endoscopists trained at our center from our country (n = 9) were invited to a survey regarding: (a) training period; (b) ESD outcomes and (c) implementation of ESD in each respective center.

Gastric cancer screening: a systematic review and meta-analysis.

Background And Aims: Gastric cancer (GC) screening is recommended in high-risk populations, although screening methods and intervals vary. In intermediate-risk populations, screening through esophagogastroduodenoscopy (EGD) may be considered depending on local resources. The aim of this study was to compare GC screening methods regarding effect on mortality, diagnostic yield and adherence.

Best additional management after non-curative endoscopic resection of esophageal squamous cell carcinoma: a systematic review and meta-analysis.

Introduction: Endoscopic resection (ER) is an accepted first-line treatment for superficial esophageal squamous cell carcinoma (ESCC), but when curative resection is not achieved, further treatment is not standardised. We aimed at evaluating outcomes of management strategies (esophagectomy, chemoradiotherapy/radiotherapy (CRT/RT) or follow-up (FUP)) after a non-curative ESCC ER.

Methods: A systematic review was performed evaluating outcomes of different management strategies after ESCC submitted to primary ER (T1a/T1b), without curative criteria (R1/Rx, T1a-m3/T1b, lymphovascular invasion (LVI) or poor differentiation).

COVID-19 and endoscopic management of superficial gastrointestinal neoplastic lesions: a multinational cross-sectional survey.

Introduction: We aimed to report the impact of the pandemic lockdown period on the treatment and prognosis of superficial gastrointestinal neoplastic lesions.

Methods: A survey was completed by 11 centers from four continents regarding postponements during the early lockdown period of the pandemic, and the same period in 2019.

Results: In 2020, 55 % of the scheduled procedures were deferred, which was 11 times higher than in 2019; the main reasons were directly related to COVID-19.

Image-enhanced endoscopy for gastric preneoplastic conditions and neoplastic lesions: a systematic review and meta-analysis.

BACKGROUND : Image-enhanced endoscopy (IEE) improves the accuracy of endoscopic diagnosis. We aimed to assess the value of IEE for gastric preneoplastic conditions and neoplastic lesions. METHODS : Medline and Embase were searched until December 2018.

Long-term follow-up after endoscopic submucosal dissection of colorectal lesions in a Spanish cohort.

Introduction: ESD in the colon is an increasingly important technique in Western countries. There are few studies that include long term follow-up.

Aim: to analyze the long term recurrence free survival rate after ESD and to compare recurrence rates according to different variables.

Endoscopic submucosal dissection for gastric epithelial lesions: long-term results in a Spanish cohort.

Introduction: endoscopic submucosal dissection for gastric lesions (ESD-G) is a technique that allows en-bloc resection of early gastric tumors, with a cure rate similar to that of surgery but lower morbidity and mortality rates.

Objective: to assess total survival, disease-free survival and relapse rate during the course of disease in a Spanish cohort of patients undergoing ESD-G.

Material And Methods: this was a prospective observational study of patients undergoing ESD-G from 2008 to 2015, with a follow-up ranging from six to 60 months.

[Detection of an intrapulmonary shunt in patients with liver cirrhosis through contrast-enhanced transcranial Doppler. A study of prevalence, pattern characterization, and diagnostic validity].

Introduction: Intrapulmonary vascular dilatations (IPVD) are considered a complication of cirrhosis. The technique of choice for their diagnosis is contrast-enhanced echocardiography (CEE). The aim of this study was to determine the usefulness of contrast-enhanced transcranial Doppler (CETD) in the diagnosis of IPVD.
