A videocápsula endoscópica (VCE) constitui uma ferramenta diagnóstica particularmente útil na avaliação do intestino delgado. O objetivo deste estudo foi avaliar o impacto da VCE na abordagem terapêutica de doentes com doença de Crohn (DC).

A doença inflamatória intestinal (DII) extensa e de longa duração acarreta um risco aumentado de cancro colorretal (CCR). Apesar disso, o rastreio do CCR na DII não é uniforme, em parte por ausência de critérios de qualidade validados. Neste sentido, um grupo de experts reviu a evidência e propôs critérios de qualidade neste contexto. Com este trabalho pretendeu-se auditar o cumprimento dos critérios de qualidade propostos na população com DII de um centro terciário.

Device-assisted enteroscopy, and particularly double-balloon enteroscopy (DBE), allow deeper investigation and endoscopic therapy in the small bowel. During these exams, blood or hematic residues are a frequently finding. Recently, many studies have been published regarding the application of artificial intelligence (AI) to different endoscopic modalities. Convolutional Neural Networks (CNN) are a multi-layer AI architecture with high performance levels for image analysis. We aimed to develop a CNN-based algorithm for automatic detection of blood or hematic residues in DBE exams.

As complicações associadas as deiscências e fístulas anastomóticas possuem um elevado impacto na morbimortalidade. A terapêutica de vácuo por via endoscópica é atualmente reconhecida como uma importante arma na abordagem e resolução destas complicações.

Endoscopic submucosal dissection (ESD) is a minimally invasive technique to en bloc resect superficial tumors, independently of size. However, for giant gastrointestinal superficial neoplasia, the risk of invasive cancer is higher and ESD is typically challenging. Despite increasing literature on giant resections, data on efficacy and safety is still lacking.

Argon plasma coagulation (APC) is an ablative therapy used for a wide variety of indications throughout the gastrointestinal tract. There are no data on continued use of antithrombotics with respect to the risk of bleeding after APC. Therefore, current ESGE guideline does not provide any guidance in this regard. This study aimed to assess post procedure bleeding risk and to identify its risk factors.

O alvo na gestão da Doença de Crohn (DC) é a remissão completa da atividade inflamatória, com cicatrização da mucosa. O Score de Lewis é amplamente usado na Enteroscopia por Cápsula para quantificar a atividade inflamatória no Intestino Delgado na DC. Todavia, a relação da atividade da doença traduzida pelo Score de Lewis, com o estado nutricional destes doentes não está completamente esclarecido.

Esophagogastroduodenoscopy (EGD) is the gold standard for diagnosis and follow up of gastric protruding lesions. Nevertheless, it is an invasive procedure, often not tolerated by patients. Capsule endoscopy (CE) has emerged as a minimally invasive, patient friendly alternative to EGD. The application of artificial intelligence (AI) for automatic analysis of CE images has provided promising results. Convolutional Neural Networks (CNN) are a multi-layer artificial intelligence architecture with high performance levels for image analysis. The application of these automated algorithms for detection of gastric protruding lesions in CE images has not been explored. This pilot study aimed to develop and test a CNN for automatic detection gastric protruding lesions in CE images.

Device-assisted enteroscopy, and particularly double-balloon enteroscopy (DBE), allow exploration of a deeper small bowel, and have the advantage of allowing tissue sampling and therapy. Suspected mid-gastrointestinal bleeding is the most frequent indication for DBE, and vascular lesions are the most commonly found lesions in these patients.

Lesions involving the ampulla of Vater have traditionally been managed by surgical resection, albeit with significant morbidity. Endoscopic papillectomy (EP) is increasingly recognized as an efficacious and safer treatment option. This study aims to evaluate the safety and efficacy of endoscopic papillectomy for early ampullary tumours in a single tertiary referral center.
