Comparative Study
Regional colon transit in patients with dys-synergic defaecation or slow transit in patients with constipation.
To differentiate dys-synergic defaecation (DD) from normal function and slow transit constipation (STC). ⋯ DD is associated with delayed overall colonic transit at 48 h and AC t(1/2) compared with healthy controls. Regional scintigraphic transit profiles differentiate DD from STC and facilitate identification of a subgroup of patients with constipation.

Comparative Study
Long-term risk of colorectal cancer after adenoma removal: a population-based cohort study.
Previous studies examining the incidence of colorectal cancer after polypectomy have provided discordant findings. The aim of this study was to compare the risk of colorectal cancer after adenoma removal in routine clinical practice with the risk in the general population. ⋯ In routine practice, the risk of colorectal cancer after adenoma removal remains high and depends both on initial adenoma features and on colonoscopy surveillance practices. Gastroenterologists should encourage patients to comply with long-term colonoscopic surveillance.
