RESUMEN
Objectives: In 2022, the Biliary Atresia and Related Diseases (BARD) community reached a consensus for the definition of suspected and confirmed cholangitis for biliary atresia (BA) patients after hepatoportoenterostomy (HPE). This study assessed the new standardized BARD definition in a retrospective, multicenter cohort study. Methods: We included BA cases managed between 2010 and 2020 at the Hannover Medical School and Geneva University Hospitals' Swiss Pediatric Liver Center. The standardized BARD cholangitis definition assesses four clinical items and four imaging/laboratory items to define cholangitis. The definition was retrospectively applied to all BA cases having presented, according to their physician, cholangitis within the first year after the HPE. The diagnosis defined by the standardized BARD definition was compared with the final clinical diagnosis made by physicians. The Spearman's correlation coefficient was used to test for correlation between diagnoses made by standardized and clinical appreciation. Results: Of 185 consecutive BA patients, 59 (32%) had at least one episode of cholangitis within the first year after HPE. The correlation between the clinician's impression and the standardized BARD definition was very strong (r = 0.8). Confirmed cholangitis definition coincided with the clinician's impression (2.5 [±0.7]/4 clinical items, 2.6 [±0.5]/4 imaging/laboratory items). For suspected cholangitis, the threshold for diagnosis was lower within the standardized BARD definition (1.1 [±0.3]/4 clinical items, 2.2 [±0.8]/4 laboratory/imaging items). Conclusions: This first retrospective application of the standardized BARD cholangitis definition reveals a very strong correlation with the physician's assessment before standardization. A prospective study is needed to further refine the standardized definition for cholangitis in BA patients.
RESUMEN
Objectives: Choledochal malformation (CM) is a rare disease that can lead to malignancy and potential long-term sequelae despite surgical resection. There is no long-term follow-up data on patients after CM resection in Germany. We aimed to determine the long-term outcome of our patients with a duration of follow-up >10 years and focused on long-term sequelae and health-related quality of life (HRQOL). Methods: All patients who had undergone CM-resection in our department from 01/1978 to 06/2009 were contacted. Patients were interviewed about postoperative complications and their present medical attendance. HRQOL was determined using Pediatric Quality of Life Inventory 4.0 (PedsQL), version for adults. The PedsQL scales the HRQOL from 0 to 100, with higher scores indicating a better HRQOL. Scores were compared to those published for a healthy population. Results: Out of 56 patients who were contacted, 23 (41â¯%) participated. The median age at time of surgery was 3.1 years (6 days-16.1 years) and at time of the survey 24.3 years (11.1-53.8 years). Eighteen patients (78â¯%) had ceased their gastroenterologic follow-up at a median time of 4.3 years after surgery. Five (22â¯%) were still in gastroenterologic follow-up, two of these had an uneventful clinical course, and three (13â¯%) had ongoing complications attributed to the CM. One of these had undergone hemihepatectomy 34 years postoperatively due to bile duct stenosis, one had undergone removal of bile duct stones 14 years postoperatively, and one suffered from portal vein thrombosis with esophageal and jejunal varices. There was no mortality in our series. Median total HRQOL score was 89. There was no significant difference in the median total health, physical health, and psychosocial health scores of our patients in comparison to the healthy population. Conclusions: We confirmed that the majority of patients after CM resection are lost to follow-up. Those who answered our questionnaire showed a good HRQOL. Given the high rate of severe long-term complications and the life-long risk of malignancy, we recommend a transition program for all patients.
RESUMEN
RATIONALE AND OBJECTIVES: There is universal interest in increasing sustainability in health care, including in imaging. We studied and characterized energy consumption in a representative imaging department in Denmark to identify and quantify the effect of specific optimizations. METHODS: Protocols and energy parameters for the three main scanner modalities along with supportive systems and workflows were monitored and scrutinized. Potential savings were measured and/or calculated. RESULTS: Only few optimizations were identified at the protocol level. However, examination of usage patterns and cooling systems revealed numerous potential optimizations which fell into three categories. 1) Optimizations requiring minimal changes in installations or workflows, for example, reduction of bed-position time, 2) optimizations requiring altered work flows such as strict adherence to timed shut-down procedures and 3) optimizations requiring retro-fitting equipment, typically at considerable monetary expense, for example fitting variable flow control on pumps. The single biggest identified optimization was raising the temperature of the circulating cooling water. CONCLUSION: This study highlights the complexity of increasing sustainability in health care, specifically in imaging. We identified multiple potential optimizations but also technical, monetary and organizational barriers preventing immediate implementation.
