- W4308204145 abstract "It is our privilege to serve as guest editors for this special issue of robotic endoscopy in Techniques and Innovations in Gastrointestinal Endoscopy. In this series, we aim to review current engineering developments in the field of robotic endoscopy, highlight clinical applications in the areas of gastric and colorectal endoscopic submucosal dissection (ESD) using the robotic endoscope, and explore potential future developments to enhance the capabilities of robotic endoscopy. When the endoscope was first invented, its primary function was to perform diagnostic evaluation of the gastrointestinal tract. Small lesions could also be sampled using endoscopic biopsy forceps. At that time, if large invasive lesions were encountered, patients were routinely counseled for surgical resection as there were no suitable endoscopic instruments to facilitate their removal from the gastrointestinal tract. In recent decades, endoscopic submucosal resection (EMR) and ESD were introduced as techniques to resect early-stage malignant lesions. The benefit of these procedures is to allow patients to receive minimally invasive treatment for early-stage malignant lesions. Patients can then return to work earlier because the procedure is less painful, and recovery is faster than with traditional surgical resections. Nevertheless, the pace of development and improvement of endoscopic instruments did not keep up with the introduction of novel endoscopic resection techniques. Currently, endoscopists still struggle to perform tissue retraction and dissection using existing endoscopic instruments that lack degrees of freedom. It is akin to surgeons performing resections without being able to rotate their wrists or flex and extend their fingers. With these shortcomings, it is not surprising that procedures are plagued with complications such as iatrogenic perforation and bleeding. The emergence of flexible robotic endoscopes has radically changed the field of therapeutic endoscopy. The use of robotic endoscopy allows proceduralists to perform more precise tissue retraction and dissection. The high degrees of freedom of the robotic end-effectors mimic the wrist movements of a surgeon performing surgery. Ex vivo studies and preliminary clinical trials have also demonstrated that the enhanced maneuverability of the robotic endoscope allows proceduralists to perform therapeutic endoscopic procedures with improved ease. In this issue, Prof Rodriguez Y Baena et al review current engineering developments for robotic systems in flexible endoscopy, and Dr Galvao Neto et al describe their initial experience using a novel flexible endoscopic robotic device to perform full resection of colorectal lesions and endoscopic suturing. Regarding the use of robotic endoscopy for ESD, Prof Ho et al examine its role for gastric lesions, and Prof Chiu et al weigh in on its function for colorectal lesions. Finally, Dr Aihara et al explore possible future directions for robotic endoscopy, including its use together with artificial intelligence and three-dimensional imaging, as well as its potential application for natural orifice transluminal endoscopy surgery. We would like to thank Drs Vinay Chandrasekhara, Michael Kochman, and Lawrence Ho for the opportunity to be guest editors for this series. We also extend our gratitude to the editorial staff Ryan A. Farrell and Laura Flecha for their hard work in putting this issue together. Finally, it is our hope that readers will find this issue a valuable addition to the field of robotic endoscopy." @default.
