Point-of-care Ultrasound to Screen for Gastrointestinal Dysfunction: Image Acquisition and Interpretation

Area of Science:

• Medical Imaging
• Gastroenterology
• Emergency Medicine

Background:

• Gastrointestinal (GI) dysfunction is a significant cause of patient morbidity and high healthcare costs.
• Computed tomography (CT) is commonly used for GI symptom evaluation but involves radiation exposure, expense, and logistical challenges.
• There is a need for non-invasive, accessible diagnostic tools for bedside GI assessment.

Purpose of the Study:

• To develop and present an evidence-based protocol for point-of-care ultrasound (POCUS) image acquisition.
• To enable screening for two common types of GI dysfunction: ileus and obstruction.
• To address the limitations in provider training and standardization for GI POCUS.

Main Methods:

• The study proposes a protocol for GI POCUS, detailing probe selection, patient positioning, and image acquisition sequences.
• The protocol is designed for screening ileus and obstruction at the bedside.
• Guidance on image interpretation and protocol limitations are also reviewed.

Main Results:

• The proposed protocol aims to standardize GI POCUS for ileus and obstruction detection.
• It provides a structured approach to image acquisition and interpretation.
• The protocol serves as a foundation for improving provider confidence and skill in GI POCUS.

Conclusions:

• GI POCUS presents a valuable, radiation-free alternative to CT for evaluating GI dysfunction.
• Standardized protocols are crucial for widespread and effective adoption of GI POCUS.
• This protocol facilitates bedside decision-making for ileus and obstruction, enhancing patient care and resource management.
