With the continuous advancement of endoscopy technology and diagnosis , researchers have realized that the incidence of superficial non-ampullary duodenal epithelial tumors (SNADET) has been increasing

However, the clinical features of SNADET with malignant potential remain unclear
With the continuous advancement of endoscopy technology and diagnosis , researchers have realized that the incidence of superficial non-ampullary duodenal epithelial tumors (SNADET) has been increasing
The researchers identified 328 SNALET cases that were resected endoscopically or surgically from January 2013 to April 2019 from the endoscopy and pathology database
.
Then the clinical characteristics of these patients' low-grade mucosal tumors (n = 154) and high-grade mucosal tumors/submucosal carcinoma (HGN/SMC, n = 174) were compared
The analysis of the study results showed that in univariate analysis, tumor size, preampullary tumor location, red color and rough/nodular surface were significantly correlated with HGN/SMC
.
In the multivariate analysis, tumor size (≥10 mm) (OR: 4.
This study confirmed that the anterior ampullary position and the size of the large tumor are independent predictors of HGN/SMC type SNAET

The location of the preampullary tumor is significantly related to the gastric histological phenotype
This study confirmed that the anterior ampullary position and the size of the large tumor are independent predictors of HGN/SMC type SNAET
