BACKGROUND Most small intestinal lipomas are treated surgically,and some require repeated surgeries for multiple lipomas.However,application of endoscopic submucosal dissection(ESD)technology in the deep small intestine is rarely reported owing to the special anatomical structure of the small intestine,medical equipment limitations,and the lack of relevant experience among endoscopists.CASE SUMMARY Two patients with small intestinal lipomas treated at the Air Force Medical Center from November 2015 to September 2019 were selected to undergo balloonassisted ESD to treat the lipomas and explore the technical feasibility and safety of ESD for treating small intestinal lipomas.The two patients successfully underwent balloon-assisted ESD to treat four small intestinal lipomas,with a complete resection rate of 100%(4/4),without intraoperative or postoperative bleeding,perforation,or other complications.After 3-6 mo of postoperative follow-up,the clinical symptoms caused by the lipomas were significantly relieved or disappeared after treatment.CONCLUSION Balloon-assisted ESD is a safe and reliable new method for treating deep intestinal lipomas and shows good clinical feasibility.
