Abstract
|
|
|
|
Incidence of rectal neuroendocrine neoplasms (NEN) has increased tremendously over the decades due to disease awareness and widespread use of screening colonoscopy. Although NEN has been recognized as malignant disease, most rectal NENs are initially found as small mass confined to the submucosa, which can be removed completely through various endoscopic treatments with good prognosis. In this review, we summarize the treatment options focusing on localized T1 rectal NEN by comparing representative international guidelines and discuss current controversies on the management. We also discuss various resection techniques focusing on endoscopic resection.
