Intraobserver Variation

Background: Open surgical or endovascular abdominal aortic aneurysm (AAA) relies on precise preprocedual imaging. Purpose of this study was to assess inter- and intraobserver variation of software-supported automated and manual multi row detector CT angiography (MDCTA) in aortoiliac diameter measurements before AAA repair. Patients and methods: Thirty original MDCTA data sets (4 times 2mm collimation) of patients scheduled for endovascular AAA repair were studied on a dedicated software capable of creating two-dimensional reformatted planes orthogonal to the aortoiliac center-line. Measurements were performed twice with a four-week interval between readings. Data were analysed by two blinded readers at random order. Two different measurement methods were performed: reader-assisted freehand wall-to-wall measurement and semi-automatic measurement. Results: Aortoiliac diameters were significantly underestimated by the semi-automatic method as compared to reader-assisted measurements (p < 0.0031). Intraobserver variability of AAA diameter calculation was not significant (p > 0.15) for reader-assisted measurements except for the diameter of the left common iliac artery in reader 2 (p = 0.0045) and it was not significant (p > 0.14) using the semi-automatic method. Interobserver variability was not significant for AAA diameter measurements using the reader-assisted method and for proximal neck analysis with the semi-automatic method (p > 0.27). Relevant interobserver variation was observed for semi-automatic measurement of maximum AAA (p = 0.0007) and iliac artery diameters (p = 0.024). Conclusions: Dedicated MDCTA software provides a useful tool to minimize aortoiliac diameter measurement variation and to improve imaging precision before AAA repair. For reliable AAA diameter analysis the reader-assisted freehand measurement method is recommended to be applied to a set of reformatted CT data as provided by the software used in this study.

Abstract Introduction Colorectal cancer (CRC) has been reported in early adulthood in patients with anorectal malformation (ARM), and therefore, the need of endoscopic controls has been discussed. The aim of this study was to assess the risk of CRC in patients with ARM. Materials and Methods This was a nationwide population-based study with data from Swedish national health care registers. All patients diagnosed with ARM born in Sweden between 1964 and 1999 were identified in the National Patient Register. The same group was followed up in the Swedish Cancer Register from birth to December 31, 2014, for occurrences of CRC. Five age- and gender-matched individuals randomly selected from the Medical Birth Register served as controls for each ARM patient born between 1973 and 1999. Results A total of 817 patients (474 males) with ARM were included and followed up from birth to the end of observational period. Time of follow-up ranged from 15 to 50 years (mean: 28 years). None of the patients was diagnosed with CRC during the observational period. One case of rectal cancer and one case of sigmoid cancer were detected among the 3,760 controls. Conclusion In our study, the risk of CRC in early adulthood in patients with ARM is low. Our result does not support routine endoscopic follow-up for patients with ARM during the first decade of life.
