A brief review of diagnostic properties of point-of-care ultrasound for adult bowel intussusception: Making the case for ultrasound

Small bowel intussusception - aetiology & management

PURPOSE OF REVIEW

Adult small bowel intussusception (SBI) differs in incidence, symptomatology and management from the more commonly encountered paediatric intussusception. This review spans across the multitude of causes of adult SBI, and summarises the diagnostic work-up and management options according to recent literature.

RECENT FINDINGS

There has been an increase in use of small bowel capsule endoscopy and point-of-care ultrasound for the diagnosis of acute adult SBI.

SUMMARY

A high degree of suspicion of a malignant cause of SBI is required in the adult population. Alarm clinical features include weight loss, history of malignancy, and iron deficiency anaemia. CT remains the gold standard imaging technique as it may identify the lead point and thus aid in endoscopic or surgical management. If malignancy is excluded and no lead point is identified, serology and histology may be helpful to look for inflammatory, infective and autoimmune aetiology.

Point of Care Abdominal Ultrasound

Abdominal pain is a common emergency department complaint, and point-of-care ultrasound (POCUS) of the abdomen is increasingly being utilized to evaluate clinical manifestations. It aids in accurate diagnoses and assists in procedures, particularly in emergency and critical care settings. Imaging is often required to confirm the etiology of abdominal pain. POCUS provides the benefit of avoiding radiation exposure and enables quicker diagnosis compared to computed tomography scans. There is growing evidence of the diagnostic accuracy for numerous abdominal POCUS applications, including appendicitis, intussusception, diverticulitis, gastric ultrasound and contrast-enhanced ultrasound.

An in-Depth Examination of the Characteristics of Pre-Hospital Point-of-Care Ultrasound Training Among Emergency Medicine Residents in Laos as Part of an Overseas Elective Rotation

Introduction

Point of Care Ultrasound (POCUS) training has been offering invaluable guidance in the diagnostic process and treatment strategies, particularly in resource-limited settings. The purpose of this study was to determine participant satisfaction with the structure and scope of POCUS training in overseas elective rotation.

Material and Methods

A retrospective observational analytical study was undertaken. The study focused on EM residents from Laos who participated in the international elective rotation at the Khon Kaen University during the academic years 2020-2021 and 2022-2023. The research involved an exploration of training data related to this course, encompassing participant characteristics, the structure and scope of POCUS training, the training assessments, and post completion surveys of participants.

Results

The study involved 24 participants. The course was characterized by its status as an international elective program prehospital POCUS training for post graduate year 3 students. The duration of the rotation ranged from 2 to 4 weeks. Interestingly, in the academic year 2022-2023, the duration of POCUS training was notably extended to 8 hours, accounting for 4.76% of the total time. The training encompassed peer-to-peer didactic lectures, bedside teaching, and observational case studies at the Emergency Department (ED). The results of our survey, boasting a 100% response rate, indicated participants' contentment with the academic performance, the abundance of learning resources, and the knowledge gained from this rotation that would aid their future careers. The overall satisfaction with this course was highly rated, falling into the "satisfy" and "highly satisfy" categories. However, certain challenges were reported, including feelings of isolation due to the distance from relatives, concerns related to interpersonal relationships with colleagues, and a sense of being isolated.

Conclusion

The participants were highly satisfied to the structure and scope of this course. The overseas elective rotation significantly enhanced the knowledge of Laos EM residents' in POCUS and underscored the crucial importance of this course in EM training.
