Future challenges in gastroenterology and hepatology, between innovations and unmet needs: A SIGE Young Editorial Board's perspective
Gastroenterology, Digestive Endoscopy and Hepatology have faced significant improvements in terms of diagnosis and therapy in the last decades. However, many fields still remain poorly explored, and many questions unanswered. Moreover, basic-science, as well as translational and clinical discoveries, together with technology advancement will determine further steps toward a better, refined care for many gastroenterological disorders in the future. Therefore, the Young Investigators of the Italian Society of Gastroenterology (SIGE) joined together, offering a perspective on major future innovations in some hot clinical topics in Gastroenterology, Endoscopy, and Hepatology, as well as the current pitfalls and the grey zones.Molecular imaging in gastroenterology: A route for personalized endoscopy
With the rapid expansion and diversification of the repertoire of biological agents utilized in inflammatory bowel diseases and cancer and the increase in oncological patients in gastroenterology, visualization of single receptor or molecular target expression and the subsequent initiation of expression tailored therapy are gaining increasing attention. Through the combination of utilizing fluorescently labeled probes with high specificity towards defined molecular targets and their subsequent detection and visualization with endoscopic devices, molecular imaging is a new emerging field focusing on the receptor expression within the mucosa on a cellular level rather than on macroscopic changes.Covered metal stents in endoscopic therapy of biliary complications after liver transplantation
There is growing interest in using covered self-expandable metal stents for the treatment of benign biliary conditions, and the presence of anastomotic biliary strictures and leaks after liver transplantation provide a valuable opportunity for testing them. The performance of the stents is encouraging, and the technical success rate is high. They provide larger diameter dilation and are easily removed, and can potentially limit costs by reducing the number of procedures needed to treat anastomotic biliary strictures.Diagnostic and therapeutic role of endoscopy in gastroenteropancreatic neuroendocrine neoplasms
Gastroenteropancreatic neuroendocrine neoplasms have substantially increased over the last decades. Because of the indolent clinical course of the disease even in advance stages and the rise in the incidental diagnosis of small asymptomatic lesions, the prevalence of gastroenteropancreatic neuroendocrine neoplasms is higher than that of pancreatic, gastric and oesophageal adenocarcinomas, making them the second most prevalent cancer type of the gastrointestinal tract. This increase in the overall prevalence of gastroenteropancreatic neuroendocrine neoplasms has been paralleled by a growth in the importance of the endoscopist in the care of these patients, who usually require a multidisciplinary approach.Management and endoscopic techniques for digestive foreign body and food bolus impaction
Ingested foreign bodies, food bolus impaction, migration or retention of medical devices are frequent, in children as well as in adults. Most of these foreign bodies will naturally pass through the gastro-intestinal tract. Complications are rare but sometimes severe (oesophageal perforations are the most frequent and most feared). We aimed to review the literature on therapeutic management of digestive foreign bodies and food bolus impaction, with special focus on endoscopic indications, material, timing and techniques for removal.Management of gastrointestinal stromal tumours of limited size: Proposals from a French panel of physicians
A number of guidelines on the management of gastro-intestinal stromal tumours (GISTs) have been published, mostly based on expert consensus. However, these guidelines have generally failed to address the specific problem of GISTs of limited size (i.e. those measuring a few centimetres in diameter) with which gastroenterologists are increasingly confronted. The aim of the present work was to draw up proposals for the diagnosis and treatment of GISTs measuring less than 5 cm in diameter. For this purpose, a number of practical questions were put to a panel of French experts.
