#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.

#3428 Indocyanine green fluorescence guided resection of neuroendocrine liver metastases: A proof-of-concept study

Introduction: Even though the relative indolent character of neuroendocrine neoplasms, untreated NELM have a detrimental impact on survival outcomes. Therefore, complete resection is recommended if technically possible.

#3211 Microscopic resection margin status does not predict long-term survival in small bowel neuroendocrine tumors

Introduction: Small bowel neuroendocrine tumors (SBNETs) are increasing in incidence and are the most common small bowel malignancy. The characteristic nodal mass, which may extend high into the mesentery, can make achieving microscopically negative resection margins difficult without resecting excessive lengths of small bowel.
