The complete resection rate was higher in the ESD group (82.7%) and in the TEM group (100%) compared to the EMR group (65.5%) (<italic>P</italic> < 0.046). The complication rate was higher in the ESD group (47.8%) than in the EMR group (18.5%) (<italic>P</italic> = 0.003).

Tumor recurrence was not observed in the endoscopic resection and TEM groups, regardless of the completeness of resection. Small neuroendocrine tumors of the gastrointestinal tract can be managed reliably with both endoscopic resection and TEM.</p> </sec> </abstract>
