Abstract Introduction: Endoscopic full-thickness resection (EFTR) is a minimally invasive endoscopic technique that allows the resection of complex colorectal lesions, such as non-lifting, peri-appendicular, peri-diverticula, and subepithelial lesions. Published data suggest that EFTR has a technical success and R0 resection rates of 89 and 79%, respectively, and an adverse event rate of 12%. This study summari...
Abstract Background: Endoscopic submucosal dissection (ESD) is a minimally invasive technique for en bloc resection of superficial neoplastic lesions, independent of their size. However, for giant gastrointestinal superficial neoplasia, the risk of invasive cancer is higher, and ESD is typically challenging. Despite the increasing literature on giant resections, data on their efficacy and safety are still lacki...
Abstract Introduction: Endoscopic submucosal dissection (ESD) of lesions with severe submucosal fibrosis has been associated with worse outcomes, such as lower curative resection rate and higher incidence of adverse events. This study aims to investigate its true impact on rectal ESD performed in the West and to assess predictive factors of severe fibrosis. Methods: We conducted a retrospective study including ...
Abstract: Background: Peroral endoscopic myotomy (POEM) is an innovative achalasia treatment procedure that involves myotomy of the lower esophageal sphincter through a submucosal tunneling approach, combining the efficacy of surgical myotomy with the benefit of being a less invasive treatment. At this time, no data are available of POEM in Portugal. This study aimed to examine the safety and short-term outcome...
Introduction: Endoscopic submucosal dissection (ESD) is a minimally invasive organ-sparing endoscopic technique which allows en bloc resection of premalignant and early malignant lesions of the gastrointestinal tract regardless of size. In spite of the promising results, mainly from Japanese series, ESD is still not being widely used in western countries. This study aims to report the feasibility, safety and ef...
