Endoscopic Therapy for Acute Diverticular Bleeding.

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Diverticular bleeding constitutes a significant portion of lower gastrointestinal bleeding cases.
• Rupture of vasa recta near diverticula is the primary cause of this condition.

Purpose of the Study:

• To review the diagnostic and therapeutic role of colonoscopy in managing diverticular bleeding.
• To evaluate the efficacy and outcomes of various endoscopic hemostasis methods.
• To identify gaps in knowledge regarding long-term outcomes of endoscopic treatments for diverticular bleeding.

Main Methods:

• Review of endoscopic hemostasis techniques including injection therapy, thermal therapy, clipping, endoscopic band ligation (EBL), hemostatic powder, and over-the-scope clips.
• Analysis of clinical outcomes, focusing on initial hemostasis, early recurrent bleeding, and potential need for further interventions.
• Assessment of available data on long-term outcomes, including late and recurrent bleeding at 1 and 2 years.

Main Results:

• Colonoscopy is effective for diagnosis and treatment of diverticular bleeding with proper bowel preparation.
• Multiple endoscopic methods provide secure initial hemostasis with no significant differences in early recurrence.
• Endoscopic band ligation (EBL) may reduce the need for transcatheter arterial embolization or surgery.

Conclusions:

• Endoscopic interventions are crucial for managing diverticular bleeding, with EBL showing promise in reducing further interventions.
• Long-term efficacy and recurrence rates of endoscopic treatments for diverticular bleeding are not well-established.
• Improvements in endoscopic techniques and a multidisciplinary approach are needed for comprehensive management of diverticular bleeding.
