Abstract
Factors associated with serious colonic diverticular bleeding (CDB) are unclear, although the incidence of CDB has increased. We carried out this study to clarify factors associated with serious CDB and rebleeding. Subjects included 329 consecutive patients hospitalized for confirmed or suspected CDB between 2004 and 2021. Patients were surveyed regarding backgrounds, treatment, and clinical course. Of 152 with confirmed CDB, 112 showed bleeding from the right colon, and 40 did from the left colon. Patients received red blood cell transfusions in 157 (47.7%), interventional radiology in 13 (4.0%), and surgery in 6 (1.8%) cases. Early rebleeding within one month occurred in 75 (22.8%) patients, and late rebleeding within one year occurred in 62 (18.8%). Factors associated with red blood cell transfusion included confirmed CDB, anticoagulants, and high shock index. The only factor related to interventional radiology or surgery was confirmed CDB, which was also associated with early rebleeding. Late rebleeding was associated with hypertension, chronic kidney disease and past CDB. Right CDB showed higher rates of transfusion and invasive treatment than left CDB. Confirmed CDB had high frequencies of transfusion, invasive treatment, and early rebleeding. Right CDB seemed to be a risk for serious disease. Factors related to late rebleeding were different from those related to early rebleeding of CDB.
