Single-port rectal surgery may reduce postoperative pain. Although CRP levels were lower at some time points, results of the present randomized, pilot study suggest that the trauma-induced inflammatory response of single-port operations may be similar to the trauma-induced inflammatory response of conventional laparoscopic surgery.

Levels of 5mC or H3K9Me3 appear stable in most pre-analytical settings if blood samples are stored at room temperature until centrifugation.

Implementation of population screening for colorectal cancer by direct colonoscopy or follow-up colonoscopy after a positive fecal blood test has challenged the overall capacity of bowel examinations. Certain countries are facing serious colonoscopy capacity constraints, which have led to waiting lists and long time latency of follow-up examinations. Various options for improvement are considered, including increased cut-off values of the fecal blood tests. Results from major clinical studies of blood-based, cancer-associated biomarkers have, however, led to focus on a Triage concept for improved selection to colonoscopy. The Triage test may include subject age, concentration of hemoglobin in a feces test and a combination of certain blood-based cancer-associated biomarkers. Recent results have indicated that Triage may reduce the requirements for colonoscopy by around 30%. Such results may be advantageous for the capacity, the healthcare budgets and in particular, the subjects, who do not need an unnecessary, unpleasant and risk-associated bowel examination.
