Although lower gastrointestinal
bleeding generally has a less severe course and stops spontaneously in most cases without therapeutic intervention, some patients require endoscopic, surgical, or angiographic treatment depending on the nature of the
bleeding. We applied endoscopic band
ligation (EBL) with a water-jet scope to
bleeding colonic diverticula and evaluated the efficacy and safety of EBL retrospectively. Five consecutive patients were diagnosed as having colonic diverticular
hemorrhage, and were treated with EBL at St Luke's International Hospital in Tokyo from June 2009 to August 2009. Comorbid diseases, usage of anti-platelet agents,
hemoglobin level on admission, procedural time, complications such as perforation and
abscess formation, and rebleeding after EBL were retrospectively evaluated. In all cases, EBL achieved successful immediate hemostasis without any procedural complications. In four of five cases,
bleeding colonic diverticula were everted after EBL. The mean length of
hospital stay after EBL was 5 days (range 4-8 days). No patient exhibited clinical evidence of further
bleeding during the mean follow-up period of 3 months (range 2-4 months), and no further intervention was needed after EBL. EBL with a water-jet scope is considered to be a safe and effective endoscopic treatment for colonic diverticular
hemorrhage.
