#3986 The application of 68Ga-DOTANOC PET/CT after endoscopic submucosal dissection for patients with rectal NET

Introduction: Some rectal neuroendocrine tumors (NETs) are accidentally detected by colonoscopy screening. Due to the lack of cognition of endoscopic feature of rectal NET, endoscopic tumor resection has always done without metastasis screening.

#3973 Clinical value of endoscopic submucosal dissection combined with chemotherapy for treatment of esophageal neuroendocrine carcinoma

Introduction: Due to the lack of large-scale data describing the clinical and pathological characteristics of esophageal neuroendocrine carcinoma（eNEC), there is no standardized diagnosis and treatment of eNEC currently.

#3828 Role of endoscopic resection margin (R1) in the clinical outcome of patients with neuroendocrine neoplasia

Introduction: Endoscopic resection margin R1 (ER1) describes neoplasia presence at lateral and/or deep margin. Highest rate of R1 resection occurs in duodenal NENs (d-NENs) where advanced resection techniques [endoscopic submucosal dissection (ESD); full thickness resection (EFTR)], are more difficult to apply. In gastric (g-NENs) and rectal NENs (r-NENs), due to favourable anatomy, ESD or EFTR obtain lower rates of R1 resection.

#3667 Outcome of endoscopic submucosal dissection for rectal neuroendocrine neoplasms – A multicentre study

Introduction: Recent guidelines recommend advanced endoscopic resection techniques, such as Endoscopic Submucosal Dissection (ESD), for the treatment of rectal neuroendocrine neoplasms (R-NENs) under 15mm due to high rate of positive margins at Endoscopic Mucosal Resection (EMR).

#3665 Endoscopic submucosal dissection for gastric neuroendocrine neoplasms – A multicentre retrospective study

Introduction: The optimal endoscopic management for Gastric Neuroendocrine Neoplasms (G-NENs) is yet to be determined, and data are limited in the literature.
