Surgeon-performed ultrasound for the staging of acute diverticulitis: Preliminary results of a prospective study

INTRODUCTION

Although contrast-enhanced abdominal computed tomography (CEACT) is still considered the criterion standard for the assessment of suspected acute diverticulitis, in recent years, the use of point-of-care ultrasound (POCUS) has been spreading more and more in this setting. The aim of this study was to compare CEACT to POCUS for the diagnosis and staging of suspected acute diverticulitis.

METHODS

This is a prospective study conducted on 55 patients admitted to the emergency department of two Italian Hospitals with a clinical suspicion of acute diverticulitis between January 2014 and December 2017. All the patients included underwent POCUS first and CEACT immediately afterward, with the diagnosis and the staging reported according to the Hinchey (H) classification modified by Wasvary et al. [Wasvary H, Turfah F, Kadro O, Beauregard W. Same hospitalization resection for acute diverticulitis. Am Surg. 1999;65:632-635.] Three surgeons performed all the POCUS, and the same two radiologists retrospectively analyzed all the CEACT images. The radiologists were informed of the clinical suspicion but unaware of the POCUS findings. The CEACT was used as the criterion standard for the comparison.

RESULTS

The final cohort included 30 females (55%) and 25 males (45%). The median age was 62 years (range, 24-88 years), and the median body mass index was 26 kg/m2 (range, 19-42 kg/m2). Forty-six of 55 patients had a confirmed diagnosis of acute diverticulitis on both POCUS and CEACT, whereas, in 7 patients, the diagnosis was not confirmed by both methods. Point-of-care ultrasound sensitivity and specificity were 98% and 88%, respectively. Point-of-care ultrasound positive and negative predictive values were 98% and 88%, respectively. Point-of-care ultrasound accuracy was 96%. Point-of-care ultrasound classified 33 H1a, 11 H1b, 1 H2, and 1 H3 acute diverticulitis. This staging was confirmed in all patients but three (93%) by CEACT.

CONCLUSION

Point-of-care ultrasound appeared a reliable technique for the diagnosis and the staging of clinically suspected H1 and H2 acute diverticulitis. It could contribute in saving time and resources and in avoiding unnecessary radiation exposure to most patients.

The "Case-Based Learning Conference" Model at EMINDIA2017: A Novel Implementation of Problem-Based Educational Paradigm

INDUSEM was established as an INDO-US Satellite Knowledge Network in 2005. It brought together the academic leaders and innovators from India and the US with the goal of creating collaborative synergies and creative solutions to advance the knowledge and science of emergency medicine (EM) in India. Since 2005, the leadership of INDUSEM devoted substantial resources, effort, and expertise to ensure that newly implemented clinical institutes and training programs have the necessary resources and logistical support to effectively advance EM and Traumatology Sciences in India. As a result, significant synergies and progress were achieved toward establishing EM training programs and building clinical infrastructure through education, grant funding, research, skills development, bidirectional collaborations, and sustained influence on public health policy development. As INDUSEM's mission matures, its efforts will increasingly focus on creating long-term sustainability across clinical, didactic, educational, outreach, health policy, and research domains. In this joint statement, the authors describe the evolution of INDUSEM's institution of INDO-US Summit into the World Academic Congress of EM , with the parallel inception of an India-centric academic enterprise, EMINDIA.
