ERCPMP: an endoscopic image and video dataset for colorectal polyps morphology and pathology.
BMC Res Notes
December 2024
Department of Computer Engineering, Science and Research Branch, Islamic Azad University, Tehran, Iran.
This dataset contains demographic, morphological and pathological data, endoscopic images and videos of 191 patients with colorectal polyps. Morphological data is included based on the latest international gastroenterology classification references such as Paris, Pit and JNET classification. Pathological data includes the diagnosis of the polyps including Tubular, Villous, Tubulovillous, Hyperplastic, Serrated, Inflammatory and Adenocarcinoma with Dysplasia Grade & Differentiation.

Article Synopsis
- - Colorectal cancer (CRC) is a serious disease that can be detected early using colonoscopy, but identifying polyps visually can be challenging due to varying lighting conditions.
- - The article introduces a new technique called Enhanced Scattering Wavelet Convolutional Neural Network (ESWCNN) which combines CNN and Scattering Wavelet Transform to improve the accuracy of polyp classification.
- - ESWCNN achieved impressive results with 96.4% accuracy in classifying three types of polyps and 94.8% accuracy in a two-class scenario, showing it outperforms traditional CNN models in identifying different polyp types.
Serrated Lesions in Inflammatory Bowel Disease: Genotype-Phenotype Correlation.
Int J Surg Pathol
February 2021
Medical University of Graz, Graz, Austria.
Background: Patients with inflammatory bowel disease (IBD) and hyperplastic/serrated polyposis have an increased risk of colorectal cancer. The aim of our study was to elucidate the nature of serrated lesions in IBD patients.
Materials And Methods: Sixty-five lesions with serrated morphology were analyzed in 39 adult IBD patients.
Addressing Racial Disparity in Colorectal Cancer Screening With CT Colonography: Experience in an African-American Cohort.
Clin Colorectal Cancer
June 2018
Department of Radiology, University of Wisconsin School of Medicine and Public Health, Madison, WI.
Background: Incidence and mortality from colorectal cancer (CRC) are higher among African Americans where CRC screening rates lag behind non-Hispanic whites. The purpose of this investigation was to evaluate CT colonography (CTC) performance and outcome measures in an African-American cohort.
Materials And Methods: This study is an institutional review board-approved and Health Insurance Portability and Accountability Act-compliant study.
Attenuated polyposis of the large bowel: a morphologic and molecular approach.

Attenuated polyposis could be defined as a variant of familial adenomatous polyposis (FAP) in which synchronous polyps of the large bowel range between 10 and 99. We analysed all cases of attenuated polyposis observed over the last 30 years with the objectives: (A) to classify the disease according to different type and proportion of polyps; (B) To ascertain the contribution of APC and MutYH genes; (C) to discover features which could arise the suspicion of mutations; (D) To obtain indications for management and follow-up. 84 individuals in 82 families were studied.
