Quality Metrics of a Fecal Immunochemical Test-Based Colorectal Cancer Screening Program in Korea.

Background/aims: Knowledge regarding the quality metrics of fecal immunochemical test (FIT)-based colorectal cancer screening programs is limited. The aim of this study was to investigate the performance and quality metrics of a FIT-based screening program.

Methods: In our screening program, asymptomatic subjects aged ≥50 years underwent an annual FIT, and subjects with positive FIT results underwent a subsequent colonoscopy.

Patients' Preferences for Primary Colorectal Cancer Screening: A Survey of the National Colorectal Cancer Screening Program in Korea.

Background/aims: The adoption of colonoscopy as a primary colorectal cancer (CRC) screening technique has been argued for in Korea, without evidence of patient preferences. This study aimed to investigate patients' preferences for the primary CRC screening test for the National Cancer Screening Program (NCSP).

Methods: Between June and August 2016, 414 individuals aged ≥50 years who participated in the NCSP were prospectively invited to complete a questionnaire regarding their preferences for the primary CRC screening test and the reasons for their selection.

Cerebral venous thrombosis in a patient with Crohn's disease.

Patients with inflammatory bowel disease (IBD) have an elevated risk of venous thromboembolism compared with the general population.

However, cerebral venous thrombosis is rarely associated with IBD.

Anaphylactic shock caused by ingestion of polyethylene glycol.

Colonoscopy is the current standard method for evaluation of the colon. The diagnostic accuracy and therapeutic safety of colonoscopy depend on the quality of colonic cleansing and preparation. Generally, all these preparations have been demonstrated to be safe for use in healthy individuals without significant comorbid conditions.
