A study conducted thanks to the participation of 329 patients with 345 rectal neuroendocrine tumors non-metastatic r-NETs of endoscopy-estimated sizes ≤2 cm, recruitment supported by APTED, and conducted in 16 French hospitals with  recently published important findings. The survey concludes the resection of small rectal neuroendocrine tumors often requires multiple procedures. Training of endoscopists is necessary in order to better recognize these tumors and to perform the appropriate resection technique. The study tries to improve the management of non-metastatic rectal neuroendocrine tumors diagnosed endoscopically as in Western European countries, r-NETs are not yet sufficiently recognized by endoscopists (18%).
