Endoscopic full-thickness resection of adenomas or subepithelial tumors is a novel and promising endoscopic technique. There have been several recent studies of full-thickness resection device (FTRD) use in the colon, but data regarding its use and efficacy in the duodenum are still limited.
A 64-year-old female underwent resection of a recurrent adenoma of 7 mm in size in the duodenum after FTRD use for an adenoma eight months prior. The biopsies revealed a low-grade adenoma. The adenoma was removed using the gastroduodenal FTRD, and the pathology results revealed clear margins. Except for minor bleeding that was treated by argon plasma coagulation, no further complications occurred.
Repeat use of the FTRD appears to be a safe and efficacious approach for the treatment of recurrent duodenal lesions. Further prospective studies are needed to investigate the long-term safety and utility of repeat FTRD use after Endoscopic full-thickness resection.
Core tip: Endoscopic full-thickness resection using the full-thickness resection device (FTRD) is a promising technique for resection of adenomas but has not been extensively investigated in duodenal adenomas. We present a case of a recurrent duodenal adenoma after previous full-thickness resection with successful use of repeat FTRD.
