Effectiveness of Colonoscopy in Reducing Incidence of Late-stage Colorectal Cancer Within an Opportunistic Screening Program.

Background: The effectiveness of colonoscopy in preventing colorectal cancer (CRC) within opportunistic screening programs has not been clearly established. The aim of this study was to analyze the effectiveness of colonoscopy within an opportunistic screening program using nested case-control study.

Methods: Subjects who received a diagnosis of CRC (CG) between the ages of 50 and 90 years were included and matched by age and gender in a 1:5 ratio with patients without CRC diagnosis (COG) during the period 2015 to 2023.

Intracorporeal anastomosis could be associated with a higher lymph node yield in right colon cancer surgery: Results of the ICA-LATAM study, a retrospective, multicentre, comparative analysis in Latin America.

Aim: The aim of this work was to compare lymph node (LN) yield in patients operated on for right colon cancer (RCC) using a laparoscopic approach between those receiving an intracorporeal (ICA) or extracorporeal anastomosis (ECA).

Method: This is a retrospective multicentre study involving patients operated on for RCC in nine tertiary referral centres in Latin America during a 2-year period. The main comparative outcome between groups was the number of LNs harvested between groups.

Stoma-free survival after anastomotic leak following rectal cancer resection: worldwide cohort of 2470 patients.

Background: The optimal treatment of anastomotic leak after rectal cancer resection is unclear. This worldwide cohort study aimed to provide an overview of four treatment strategies applied.

Methods: Patients from 216 centres and 45 countries with anastomotic leak after rectal cancer resection between 2014 and 2018 were included.
