Abstract
Objective To evaluate the safety and feasibility of endoscopic ultrasonography (EUS)-guided dehydrated ethanol lavage on treatment of pancreatic cystic neoplasms (PCN). Methods The data of 15 patients with PCN treated by EUS-guided dehydrated ethanol lavage in Nanjing Drum Tower Hospital from April 2014 to December 2016 were retrospectively analyzed. All the patients underwent EUS-guided fine needle aspiration, and then the cyst cavity was lavaged with dehydrated ethanol. The curative effects and complications were evaluated after the procedure. Results Each patient had one operation and all the operations were successful. No operation-related intraoperative or postoperative complications occurred. Patients were followed up for a median time of 15 months (range from 3-30 months). Twelve patients finished a long term follow-up, including 6 cases of complete remission and 6 cases of partly remission. None of the patients underwent surgical resection. Conclusion Dehydrated ethanol lavage is safe and feasible for treatment of PCN. Key words: Endoscopic ultrasonography; Dehydrated ethanol lavage; Pancreatic cystic neoplasms; Efficiency; Safety
