Core Tip

Core tip: Rectal neuroendocrine tumors increase quickly and steadily. Although transanal endoscopic microsurgery (TEM) was widely used for rectal neoplasms, the application of TEM in the full-thickness excision of rectal neuroendocrine tumors has not been well investigated. We analyzed data of all rectal neuroendocrine tumor patients who underwent local full-thickness excision using TEM as a primary excision or as complete surgery after incomplete resection by endoscopic polypectomy. The results suggested that full-thickness excision using TEM is a safe, minimally invasive procedure which could achieve complete resection, and might be a first surgical option for complete removal of higher rectal neuroendocrine tumors of less than 2 cm.
