Colorectal cancer (CRC) is one of the most common causes of cancer mortality in the world. Serrated lesions are responsible for 10 to 20% of all CRCs. Serrated polyps, particularly sessile serrated adenomas (SSA) and traditional serrated adenomas (TSA), have a subtle appearance and proximal location, and therefore have a high miss rate. The objective of this review was to evaluate the available evidence on the use of various endoscopic interventions for improving serrated lesion detection rate, thus reducing CRC related mortality.

Introduction: Colorectal non-polypoid lesions (NPLs) are flat, hard-to-detect and mainly right-sided lesions. We aimed to assess the prevalence and endoscopic features of NPLs lesions in a large cohort of screening patients in Northern Italy.
Methods: FIT-positive subjects between 50 and 69 years old who had undergone at least a screening colonoscopy from March 2005 to December 2017 at the Endoscopy Unit of Ferrara were included.
Connecting the dots: Low-grade appendiceal mucinous neoplasms and serrated polyps in the appendix.

Objective: This study aimed to examine the relationship between low-grade appendiceal mucinous neoplasms (LAMNs) and serrated polyps (SPs) of the appendix, both characterized by KRAS mutations and overlapping morphologic features.
Methods: We analyzed 27 cases of LAMN and 24 cases of SP from archival records, reviewed pathology, and performed molecular analysis on select cases. Four cases initially diagnosed as LAMN were excluded for not meeting diagnostic criteria, and 1 SP case was reclassified as LAMN.

Background And Aims: Adenoma detection rate (ADR) serves as a primary quality metric in colonoscopy. Various computer-aided detection (CADe) tools have emerged, yielding diverse impacts on ADR across different demographic cohorts. This study aims to evaluate a new CADe system in patients undergoing colonoscopy.

Aims: WNT signalling pathway dysregulation is often a critical early component in colorectal neoplasia, particularly the chromosomal instability pathway. Using two WNT reporters, and , we sought to assess whether these polyps demonstrate predictable expression patterns and if these patterns show diagnostic value.
Methods: We evaluated 23 adenomas (TA), 23 sessile serrated lesions (SSLs), 14 SSL with dysplasia and 38 traditional serrated adenomas (TSA).
Comparison of Adenoma Detection Rate Between Three-dimensional and Standard Colonoscopy: A Multicenter Randomized Controlled Trial.

Background And Study Aim: Improvement of adenoma detection rate (ADR) effectively reduces the subsequent incidence of colorectal cancer (CRC). Three-dimensional (3D) colonoscopy provided more anatomical details than standard two-dimensional (2D) colonoscopy and improved ADR in a simulation study. We aimed to compare the ADR between 2D and 3D colonoscopy.
