Purpose or Case Report: Bowel ultrasound is a critical component of gastrointestinal evaluation. Serial examination allows real-time assessment of disease progression or improvement, and assists the clinician in therapeutic decision making and clinical management.

The goals of this exhibit are:
1. Describe the technical approach of performing bowel ultrasound.
2. Review tips, and up to date technology that assist in optimizing studies.
3. Discuss sonographic appearance of various pathologies.
4. Review future potential techniques and applications including utility of Doppler flow and contrast enhanced ultrasound.
Methods & Materials: Bowel ultrasound studies at our institute were reviewed retrospectively with selected representative cases chosen to illustrate technical aspects and clinical indications for this procedure. Correlation was made with follow up radiology studies, clinical and/or surgical outcomes.

Necrotizing enterocolitis, inflammatory bowel disease, infectious colitis, neutropenic enterocolitis, malrotation, short bowel syndrome, appendicitis, intussusception, Meckel's diverticulitis, intestinal polyp, vascular malformations, graft versus host disease, intestinal hemorrhage, perforation, and obstruction will be discussed.
Results: Typical findings in normal and abnormal pediatric bowel exams will be illustrated. Emphasis on appropriate technique and methodology for serial examinations will be described.
Conclusions: Through this exhibit, participants will learn to utilize bowel ultrasound as a powerful tool in evaluating pediatric gastrointestinal diseases and understand how to optimize their technique.
