Background/Aims: In Asia, right-sided diverticular bleeding is more common than that of the left side. It often causes massive bleeding and difficulties in identifying the stigmata of recent hemorrhage (SRH) of colonic diverticular bleeding (CDB). This case series demonstrates the efficacy of the gel immersion method using OS-1 Jelly (Otsuka Pharmaceuticals Factory, Tokushima, Japan) in patients with CDB. Methods: This retrospective case series analyzed data of patients with CDB who underwent the gel immersion method from April 2016 to February 2020 at St. Luke’s International Hospital, Japan. All patients diagnosed with CDB who underwent the gel immersion method were included. We collected data on the site of bleeding, identification of SRH, and efficacy of the method from the electronic medical records. Results: A total of 9 patients (including 7 with right-sided CDB) underwent gel immersion method and were included in this study. SRH were successfully found in 66.7% (6/9) of patients. Moreover, effective hemostasis was achieved in 85.7% (6/7) of patients with right-sided CDB. There were no adverse events. Conclusions The gel immersion method was found to be effective, especially for massive right-sided CDB.

Background/Aims: Endoscopic band ligation (EBL) is used to treat colonic diverticular bleeding (CDB). An endoscopic variceal ligation device for esophageal varices is used as a conventional EBL device (C-EBL). A new EBL device (N-EBL) was developed by Sumitomo Bakelite Co. in August 2018. We aimed to evaluate the clinical outcomes of N-EBL compared with those of C-EBL. Methods: Seventy-nine patients who underwent EBL for CDB at St. Luke’s International Hospital, Japan, between 2017 and 2020 were included in this retrospective study. Patients were divided into the C-EBL and N-EBL groups. Their clinical outcomes, including achieving initial hemostasis, early rebleeding, procedure time, and EBL-associated adverse events, were evaluated. Results: Of the 79 patients, 36 (45.6%) were in the C-EBL group and 43 (54.4%) were in the N-EBL group. The rate of achieving initial hemostasis was 100% in the C-EBL group and 93.0% in the N-EBL group. No significant difference was noted in the early rebleeding rate between the groups (p=0.24). The N-EBL group achieved a shorter median EBL procedure time than the C-EBL group (18.2 minutes vs. 14.2 minutes, p=0.02). No adverse events were observed in either group. Conclusions The N-EBL device is safe and useful and may reduce EBL procedure time.
