ENDOSCOPIC CHARACTERISTICS AND PATHOLOGICAL ANALYSIS OF COLORECTAL LATERALLY SPREADING TUMORS
Main Article Content
Abstract
Objectives: his study aims to analyze the endoscopic and pathological characteristics of colorectal laterally spreading tumors (LSTs) to assist malignant risk stratification. Method:A total of 42 patients were enrolled with colorectal laterally spreading tumors from 11/2018 to 8/2021 in Bachmai hospital. Results: LSTs with mean diameters were 38.2 ± 18.4 cm. KUDO clasification rate of LSTs type IIIL, IV were 66.7% and 42.9, respectively. Patients with tumor diameter ≥ 40 mm accounted for 38.1%. Adenoma was the main histological type in patients with tumors of all diameters, accounting for 69%, malignancy lesion was 31%. Conclusion: LST malignancy was found to be correlated with lesion diameter, location, and morphological appearance.
