Point-of-Care Ultrasonography as an Extension of the Physical Examination for Abdominal Pain in the Emergency Department: The Diagnosis of Small-Bowel Volvulus as a Rare Complication after Changing the Feeding Jejunostomy Tube.

Abstract

Point-of-care ultrasonography (POCUS) has become the most popular modality of testing for physicians in recent years and is used for improving the quality of care and increasing patient safety. However, POCUS is not always acceptable to all physicians. To address the benefits and importance of POCUS, numerous studies have examined the use of POCUS in clinical practice and even medical education. This article aims to highlight the effects of POCUS as an extension of the physical examination, and we present a case to address the reasons it should be performed. For a man experiencing abdominal pain immediately after his feeding jejunostomy tube was changed, there was high suspicion of small-bowel volvulus after a “whirlpool sign” was observed during the POCUS, whereby mesenteric vessels presented in a whirling or spiral shape. This impression was subsequently confirmed by computed tomography. Small-bowel volvulus is a rare complication of changing a feeding jejunostomy tube. The images submitted here add to the sparse evidence from the literature on the use of POCUS as an extension of the physical examination for evaluating abdominal pain. POCUS can be used after taking the patient’s history and conducting a physical examination. The observation of a whirlpool sign may indicate the presence of a volvulus that is life-threatening.
