This study evaluated the feasibility and safety of using an injectable polyethylene glycol (PEG) hydrogel between the head of the pancreas and duodenum.<\/jats:p><jats:p>\n            Patients and methods In a multi-site feasibility cohort study of patients with localized pancreatic cancer, PEG hydrogel was injected under endoscopic ultrasound guidance to temporarily position the duodenum away from the pancreas. Procedure characteristics were recorded, including hydrogel volume and space created. Patients were monitored for adverse events (AEs) and radiotherapy toxicity.<\/jats:p><jats:p>\n            Results In all six intent-to-treat patients (four with borderline resectable, two with locally advanced disease), the ability to place and visualize PEG hydrogel and create space between the duodenum and the head of the pancreas was successful. There were no procedure-related AEs resulting in radiotherapy delay. There were no device-related AEs and no reports of pancreatitis.<\/jats:p><jats:p>\n            Conclusions PEG hydrogel was successfully placed, created space between the duodenum and the head of the pancreas, and was not associated with major toxicity. Enhancing radiotherapy for pancreatic cancer by using PEG hydrogel to create peri-duodenal space could have beneficial implications for treatment and warrants more exploration.<\/jats:p>","DOI":"10.1055\/a-2286-1995","type":"journal-article","created":{"date-parts":[[2024,3,25]],"date-time":"2024-03-25T23:56:12Z","timestamp":1711410972000},"page":"E861-E867","source":"Crossref","is-referenced-by-count":6,"title":["EUS-guided
