Deep Learning and Minimally Invasive Endoscopy: Panendoscopic Detection of Pleo...
Mascarenhas,Miguel; Mendes,Francisco; Ribeiro,Tiago; Afonsoa,João; Cardoso,Pedro Marílio; Martins,Miguel; Cardoso,Hélder; Andrade,PatríciaAbstract Introduction: Capsule endoscopy (CE) is a minimally invasive exam suitable of panendoscopic evaluation of the gastrointestinal (GI) tract. Nevertheless, CE is time-consuming with suboptimal diagnostic yield in the upper GI tract. Convolutional neural networks (CNN) are human brain architecture-based models suitable for image analysis. However, there is no study about their role in capsule panendoscopy....
Small Bowel Adenocarcinoma in a Patient with Crohn’s Disease: The Role of Ballo...
Dias,Emanuel; Saraiva,Miguel Mascarenhas; Moreira,Francisco; Cardoso,Hélder; Macedo,GuilhermeAbstract Introduction: Small bowel adenocarcinoma is a rare but well-known complication of Crohn’s disease. Diagnosis can be challenging, as clinical presentation may mimic an exacerbation of Crohn’s disease and imaging findings may be indistinguishable from benign strictures. The result is that the majority of cases are diagnosed at the time of operation or postoperatively at an advanced stage. Case Presentati...
A Gastric Lesion Revealing a Small-Cell Lung Cancer: A Rare Case

Artificial Intelligence and Capsule Endoscopy: Automatic Detection of Small Bow...
Saraiva,Miguel Mascarenhas; Ribeiro,Tiago; Afonso,João; Ferreira,João P.S.; Cardoso,Hélder; Andrade,Patrícia; Parente,Marco P.L.; Jorge,Renato N.Abstract Introduction: Capsule endoscopy has revolutionized the management of patients with obscure gastrointestinal bleeding. Nevertheless, reading capsule endoscopy images is time-consuming and prone to overlooking significant lesions, thus limiting its diagnostic yield. We aimed to create a deep learning algorithm for automatic detection of blood and hematic residues in the enteric lumen in capsule endoscopy...
Infectious Proctitis in Ulcerative Colitis: The Importance of an Accurate Diffe...
Saraiva,Miguel Mascarenhas; Ribeiro,Tiago Filipe; Macedo,GuilhermeAbstract: The authors present the case of a 62-year-old male presenting with a relapse of ulcerative colitis. He had unprotected anal intercourse with other men and his medical record was remarkable for HIV infection. He was admitted to the emergency department with bloody diarrhea, tenesmus, urgency, and recent weight loss. Laboratory workup revealed de novo mild anemia and mild elevation of inflammation param...
Vedolizumab-Induced Liver Injury
Saraiva,Miguel Mascarenhas; Ribeiro,Tiago; Dias,Emanuel; Lopes,Joanne Lopes; Cardoso,Hélder; Macedo,GuilhermeAbstract: Drug-induced liver injury is an important cause of acute liver injury. Immunomodulatory therapies, such as vedolizumab (VDZ), are being increasingly used for the treatment of several diseases, most importantly inflammatory bowel disease. Several studies have demonstrated the safety of this substance. To date, only one post-marketing study has reported a case of hepatotoxicity attributable to VDZ. The ...
Small Bowel Enteroscopy: A Joint Clinical Guideline from the Spanish and Portug...
Pérez-Cuadrado-Robles,Enrique; Pinho,Rolando; Gonzalez,Begoña; Ferro,Susana Mão de; Chagas,Cristina; Delgado,Pilar Esteban; Carretero,CristinaThe 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 r...
