Background
Endoscopic submucosal resection with a ligation device (ESMR-L) is effective for rectal neuroendocrine tumors (NETs); however, its effectiveness for duodenal NETs is unclear. This study evaluated the efficacy and safety of ESMR-L for duodenal NETs.
Methods
A total of 32 consecutive patients with duodenal NETs were treated in our hospital between December 2010 and August 2015. Among these 32 patients, we retrospectively analyzed the data of all patients who underwent ESMR-L for the treatment of duodenal NETs. ESMR-L was considered for patients in whom (1) the lesion size was ≤10 mm in diameter, (2) the lesion was located within the submucosal layer, and (3) no lymph node metastasis or distant metastasis was detected.
Results
Five patients underwent ESMR-L for the treatment of duodenal NETs. The en bloc complete resection rate was 100 %. The median procedure time for ESMR-L was 15 min (range 10–30 min). In all patients, perforation during and after the operation, and intraoperative bleeding were not observed; however, one patient experienced postoperative bleeding. During follow-up, no local recurrence or distant metastasis was noted in any of the patients.
Conclusion
ESMR-L is feasible, effective, and safe for duodenal NETs measuring ≤10 mm in diameter that are confined to the submucosal layer without metastasis.
