Early Implementation of Video Capsule Enteroscopy in Patients with Left Ventricular Assist Devices and Obscure...

Area of Science:

• Gastroenterology
• Cardiology
• Medical Devices

Background:

• Gastrointestinal bleeding (GIB) is a common complication in patients with left ventricular assist devices (LVADs), affecting up to 25%.
• Obscure GIB (OGIB) often presents without an identifiable source after standard endoscopic evaluations.
• Investigating OGIB in LVAD patients incurs significant costs and requires invasive procedures.

Purpose of the Study:

• To evaluate the diagnostic yield and effectiveness of video capsule enteroscopy (VCE) for obscure GIB in LVAD patients.
• To assess the impact of VCE on subsequent endoscopic procedures and patient outcomes.

Main Methods:

• Retrospective analysis of eight LVAD patients undergoing nine VCE studies for OGIB at a single tertiary referral center.
• Analysis of diagnostic yield, bleeding source identification, and guidance for further interventions.
• Comparison of endoscopic procedures and packed red blood cell (pRBC) transfusions before and after VCE.

Main Results:

• VCE demonstrated a 100% diagnostic yield for OGIB in LVAD patients.
• Intraluminal blood was the most frequent finding, with the jejunum being the most common site of pathology.
• Sixty-seven percent of VCE studies guided further endoscopy, leading to successful bleeding cessation in all cases.
• Post-VCE, there was a significant reduction in the total number of endoscopic procedures and pRBC transfusions.

Conclusions:

• Video capsule enteroscopy is a safe and highly effective diagnostic tool for obscure GIB in LVAD patients.
• Earlier implementation of VCE can improve patient outcomes and reduce healthcare costs.
• VCE facilitates targeted interventions, leading to successful bleeding control.
