Insights
A new endoscopic band ligation (EBL) device for colonic diverticular bleeding (CDB) is safe and effective. The novel device (N-EBL) demonstrated a shorter procedure time compared to the conventional EBL (C-EBL) device.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Colorectal surgery
Background:
- Colonic diverticular bleeding (CDB) is a common condition requiring endoscopic intervention.
- Conventional endoscopic band ligation (C-EBL) devices, adapted from esophageal variceal ligation, are used for CDB management.
- A novel endoscopic band ligation (N-EBL) device was developed to potentially improve outcomes for CDB.
Purpose of the Study:
- To compare the clinical outcomes of a new endoscopic band ligation (N-EBL) device versus a conventional endoscopic band ligation (C-EBL) device for treating colonic diverticular bleeding (CDB).
Main Methods:
- A retrospective study included 79 patients with CDB treated with EBL between 2017 and 2020.
- Patients were categorized into C-EBL and N-EBL groups.
- Outcomes assessed included initial hemostasis, early rebleeding, procedure time, and adverse events.
Main Results:
- Initial hemostasis was achieved in 100% of C-EBL patients and 93.0% of N-EBL patients.
- Early rebleeding rates did not significantly differ between the groups (p=0.24).
- The N-EBL group showed a significantly shorter median procedure time (14.2 minutes) compared to the C-EBL group (18.2 minutes, p=0.02).
- No adverse events were reported in either group.
Conclusions:
- The N-EBL device is a safe and effective option for managing CDB.
- The N-EBL device may offer the advantage of reduced procedure time compared to C-EBL.
- Further research may explore long-term efficacy and broader application of N-EBL in CDB treatment.
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.
Conclusion:
The N-EBL device is safe and useful and may reduce EBL procedure time.
