Endoscopic Treatment Outcome of Rectal Neuroendocrine Tumors Removed by Ligation-assisted Endoscopic Submucosal Resection / 대한소화기학회지

ABSTRACT

BACKGROUND/AIMS: Ligation-assisted endoscopic submucosal resection (ESMR-L) is preferred for the treatment of rectal neuroendocrine tumors because its results are better than those for endoscopic mucosal resection (EMR), and the procedure time is shorter and the incidence of complications is lower than endoscopic submucosal dissection. The aim of this study was to evaluate the clinical usefulness of ESMR-L compared with EMR for rectal neuroendocrine tumors. METHODS: From March 2007 to May 2017, 148 patients diagnosed with rectal neuroendocrine tumors were divided into ESMR-L and EMR groups and analyzed retrospectively. RESULTS: Of 148 patients with rectal neuroendocrine tumor, 120 had ESMR-L and 28 had EMR. The ESMR-L group had a significantly higher rate of complete resection and curative resection than the EMR group (93.3% vs. 75.0% and 92.5% vs. 71.4%, p=0.009 and p=0.003, respectively). CONCLUSIONS: ESMR-L for the treatment of small rectal neuroendocrine is a significantly superior modality to EMR.
