Abstract

Background: Despite accumulating evidence and recommendations for management of colonic diverticular bleeding (CDB), the changes in its clinical management and outcomes remain unknown.

Methods: We performed a retrospective tendency analysis on a biennial basis, a propensity score-matched cohort study between the first and latter half groups, and mediation analyses to compare the diagnostic and treatment methods between January 2010 and December 2019 (CODE BLUE-J Study).

Results: A total of 6575 patients with CDB were included. While the use of colonoscopy as the initial diagnostic procedure declined, the use of computed tomography (CT) increased in both the trend test and before-and-after comparisons. In hemostasis therapy, the use of endoscopic clips declined and band ligation increased. Interventional radiology remained unchanged; however, the number of surgeries decreased over time. The stigmata of recent hemorrhage (SRH) detection rate and length of hospital stay (LOS) improved significantly. Mediation analyses showed that use of a distal attachment and water-jet scope contributed to an improved SRH detection rate, and use of band ligation contributed to preventing rebleeding within 30 days.

Conclusions: Management strategies for CDB have changed in the past decade, particularly regarding the increased use of CT and decreased need for surgery. However, the main outcomes, except for the SRH detection rate and LOS, did not improve. The widespread use of distal attachment, water-jet scope, and band ligation could improve outcomes in CDB management.
