RESUMO
Small bowel obstruction in a pediatric patient following liver transplant often results from adhesions, hernias, or post-transplant lymphoproliferative disease. Here, we present an unusual and previously unreported entity - Roux-en-Y intussusception in an eight-yr-old female several years after liver transplantation. Although a rare complication, Roux-en-Y intussusception should be considered as a potential etiology in the patient presenting with bowel obstruction, with specific attention to acute presentation accompanying jaundice.

OBJECTIVE: We evaluated referring physician attitudes toward the international interpretation of radiologic images. MATERIALS AND METHODS: A five-question, scenario-based survey describing features of a hypothetic local radiology firm compared with those of its hypothetic overseas counterpart, international radiology, was sent by mail to 350 physicians from a broad range of medical and surgical specialties. One hundred nineteen physicians responded, for a response rate of 34%. Referring physicians were asked to indicate their preference for local versus international interpretation in each scenario using a 5-point Likert scale, with a score of -2 indicating a strong preference for international services, 0 indicating no preference, and 2 indicating a strong preference for local services. RESULTS: When all variables are held to be equal, referring physicians strongly prefer local services (mean score, 1.77; SD, 0.77). When international teleradiology provides either a 2-day faster turnaround time for reports or a 30 dollars lower out-of-pocket cost to the patient, referring physicians still prefer local services, although less than they did with all variables held equal (mean score, 0.42-0.44; SD, 1.30-1.40). When international teleradiology provides both a 2-day faster turnaround time and a 30 dollars lower out-of-pocket cost to the patient, referring physicians preferred international teleradiology, albeit only slightly (mean, -0.25; SD, 1.50). Finally, when the credentials of the international radiologists are perceived to be less than those of the local radiologists, even in the face of faster turnaround time and 30 dollars lower cost to the patient, referring physicians overall strongly prefer local services (mean, 1.51; SD, 0.86). CONCLUSION: Referring physicians prefer local interpretation of radiologic images to international interpretation when all things are equal. However, the timeliness of image interpretation and the cost to the patient are important factors in this decision.

PURPOSE: The purpose of this retrospective study was to investigate outcomes in children who underwent a non-diagnostic ultrasound (US) evaluating for appendicitis and to identify predictors of a negative diagnosis. METHODS: An IRB-approved retrospective chart review was performed on patients age 0-18, who underwent an abdominal US evaluating for acute appendicitis from 2004 through 2013. Clinical data and specified outcomes were recorded, and exams were categorized into non-diagnostic studies and further separated into studies where the appendix was non-visualized. RESULTS: Of the 1383 studies included for analysis, 876 were non-diagnostic for acute appendicitis (63.34%) with 777 specifically because the appendix was non-visualized. Seven hundred forty of the 876 non-diagnostic studies and 671 of the 777 non-visualized studies were ultimately considered true negatives, corresponding to a negative predictive value (NPV) of 84.47 and 86.36%, respectively. In patients with WBC <7.5×10(9)/L, the NPV of non-diagnostic and non-visualized studies increased to 97.12 and 98.86%, respectively. Patients with WBC <11.0×10(9)/L have similarly high NPVs of 95.59 and 96.99% (non-diagnostic and non-visualized). CONCLUSION: Based on the high NPV of a non-diagnostic US in children without leukocytosis, these patients may safely avoid further diagnostic imaging for the workup of suspected appendicitis.
