Article Synopsis
- Colonoscopies for colorectal cancer screening often find large non-pedunculated colorectal polyps (LNPCPs), which can be effectively treated with Endoscopic Mucosal Resection (EMR), though data on outcomes within screening programs are limited.
- A study reviewed 52 EMRs over 5 years, discovering a median polyp size of 25mm, with a small percentage showing adenocarcinoma and low complication rates.
- The results indicate that EMR successfully minimizes the need for surgery (92% avoided), with low recurrence rates and high patient compliance for follow-up surveillance, demonstrating its effectiveness in managing complex polyps.
Background: Colorectal cancer (CRC) screening services in Ireland were cancelled or postponed for periods during the COVID-19 pandemic. The aim of this study was to assess the impact of screening colonoscopy delays after a positive FIT on clinical and histopathological outcomes due to these restrictions.
Methods: Participants in the Irish National Bowel Screening Programme with a positive Immunochemical Faecal Test (FIT) during the COVID-19 pandemic (March 2020-December 2021) were included.
BowelScreen paused activity in March 2020 to prioritise the response to the COVID-19 pandemic. The aim of this study was to examine the impact of this delay. Cases affected by the pause and subsequently completed were compared to the same period in 2019.

Urgent endoscopies are, however, intended to proceed as normal with additional personal protective procedures. A perceived reduction in hospital attendances may suggest a number of urgently indicated endoscopic retrograde cholangio-pancreatographies (ERCPs) are being missed.
