Abstract
The indications for endoscopic submucosal dissection (ESD) for duodenal tumors have not yet been established. We reviewed our experience of ESD performed for duodenal tumors. We analyzed the data of a total of 13 patients with 14 duodenal lesions (excluding papillary lesions) comprising 2 early cancers, 5 adenomas, and 7 neuroendocrine tumors, who were treated by ESD between 2005 and 2011. The mean tumor diameter was 12.7 ± 14.8 mm. En bloc resection was achieved in 85.7% of the cases. The procedure time was 89.1 ± 64.6 minutes. Intraoperative perforation occurred in three cases. The mean length of postoperative hospitalization was 8.4 ± 2.4 days. Because ESD for duodenal lesions was associated with a higher incidence of perforation than ESD for lesions in other locations (stomach, esophagus, and colon) reported previously, its use for duodenal lesions should be considered with caution.
