Abstract:
Objective To study the characteristics of endoscopic diagnosis and treatment for gastrointestinal neuroendocriue tumor (GI-NETs).Methods We retrospectively collected the clinical data of 84 patients with endoscopic confirmed GI-NETs from January 2012 to November 2014, including white light, endoscopic ultrasonography, histopathology and post-treatment condition.Results Endoscopic diagnosis for NET were 84 cases, but ifnally conifrmed by pathology were 72 cases, the misdiagnosis rate was 14.3%. Of the 12 misdiagnosed cases, 5 cases were chronic inlfammation, ectopic pancreas in 2 cases, and 5 cases of hyperplasia of Brunner's glands, colorectal hyperplastic polyps, colorectal venous hemangioma, colorectal leiomyoma, metastatic squamous carcinoma respectively. Of 8 cases with EUS, all lesions derived from the submucosal layer, and 6 cases of low echo, and 2 cases of high echo (Brunner's glands) and mixed echo (venous hemangioma) respectively.Conclusions GI-NETs,which possess certain characteristics under endoscopy, may be similar with other digestive diseases, while it can increase the diagnosis accuracy by more careful observation and necessary biopsy.
