Abstract

From January 1, 2016 to July 31, 2020, our study collected 25 patients which had 26 tumors with a histological diagnosis of gastrointestinal neuroendocrine tumors (NET). Most tumors located in the rectum (84.6%), originated from the submucosa (61.1%) and were less than 2cm (100%). All tumors had clear delineation and had no lymph nodes. The tumors were removed by snare resection assisted by submucosal injections of 1/10000 adrenaline (73.1%) or by non-assisted snare resection (26.9%). The rate of complete removal was 100%. 24 patients (96.0%) achieved good results, 1 patient (4.0%) had rectal perforation after the intervention and had to undergo laparoscopic surgery for closure. On histopathology, all tumors had typical characteristics of NET. On immunohistochemistry, 8/25 patients showed expressions of several CD56 makers, Chromogranin, CK10, HE, Ki67, Neuron-specific enolase, synaptophysin. Our preliminary study showed that endoscopic resection was effective and safe in the treatment of neuroendocrine tumors
