    Development and Application of a Technique for Three-Dimensional Sialography Using Cone Beam Computed Tomography By Fatima M. Jadu BDS, MSc A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Oral Radiology Graduate Department of Dentistry University of Toronto © Copyright by Fatima M. Jadu BDS, MSc 2012 Development and Application of a Technique for Three-Dimensional Sialography Using Cone Beam Computed Tomography Fatima M. Jadu BDS, MSc Doctor of Philosophy Graduate Department of Dentistry University of Toronto 2012 ABSTRACT Introduction: Salivary gland obstructive conditions are common and may necessitate imaging of the glands for diagnosis and management purposes. Many imaging options are available but all have limitations. Sialography is considered the gold standard for examining obstructive conditions of the parotid and submandibular glands but it is largely influenced by the imaging technique to which it is coupled. Cone beam computed tomography (cbCT) is a relatively new and very promising imaging modality that has overcome many of the inherent limitations of other imaging modalities used in the past for sialography. Materials and methods: A RANDO®Man imaging phantom was used to determine the effective radiation doses from the series of plain film images that represent the current standard of practice for sialography. Similar experiments were then undertaken to determine the effective radiation doses from cbCT when varying the field-of-view (FOV) size and center, x-ray tube peak kilovoltage (kVp) and milliamperage (mA). Next, cbCT image quality, measured using the signal-difference-to-noise-ratio (SDNR) was used to determine those technical factors that optimized image quality.

  • Laparoscopic Hill Repair: 25-Year Follow-Up
    Surgical Endoscopy and Other Interventional Techniques https://doi.org/10.1007/s00464-018-6150-z Laparoscopic Hill repair: 25-year follow-up Yeseul Park1 · Ralph W. Aye1 · Jeffrey R. Watkins1 · Alex S. Farivar1 · Brian E. Louie1 Received: 29 July 2017 / Accepted: 21 March 2018 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Background The open Hill repair for gastroesophageal reflux disease and hiatal hernia is remarkably durable, with a median 10-year reoperation rate of only 3% and satisfaction of 93%. No long-term data exist for the laparoscopic Hill repair (LHR). Methods Patients who underwent primary LHR at Swedish Medical Center for reflux and/or hiatal hernia at least 5 years earlier (1992–2010) were identified from an IRB-approved database. There were 727 patients who met inclusion criteria, including 648 undergoing repair for reflux and 79 for paraesophageal hernia. Two questionnaires were administered via mail to evaluate long-term quality of life using validated GERD-HRQL, Swallowing score, and global satisfaction score. Outcomes were defined by GERD-HRQL score, Swallowing score, resumption of proton pump inhibitor (PPI) therapy, need for reoperation, and global satisfaction with overall results. Results Two hundred forty-two patients completed and returned the survey (226 lost to follow-up, 90 deceased, 3 denied undergoing LHR, 166 non-responders), of which 52% were male. The average age at the time of surgery was 49.5 years. Median follow-up was 18.5 years (range 6.2–24.7). The average GERD-HRQL score (7.1) and the average Swallowing score (39.9) both indicated excellent symptomatic outcomes.
