  • A five year Canadian laparoscopic adjustable gastric band experience

    Todd W. Swanson   Bao Q. Tang   Con H. Rusnak   David F. Schaeffer   Bradley J. Amson  

    BackgroundThe aim of this study was to review 5 years of laparoscopic adjustable gastric band (LAGB) procedures in which low-pressure bands were used.MethodsAll LAGB cases at the authors' center were retrospectively analyzed. A survey of these patients was conducted in 2008 and 2009.ResultsOf 90 LAGB patients, 86 were surveyed. Follow-up averaged 17.5 months. Weight loss averaged 24.8 ± 19.4 kg. Weight loss averaged 2.7 kg/mo and did not significantly drop over the last 10.7 months (2.7 vs 1.5 kg/mo, P = .16). Excess body weight loss was 27.5%, 39.1%, and 67.2%in the first, second, and following years, respectively. Patients averaged 4.14 adjustments of their bands and vomited 2.13 times per week. The mortality rate was 0%. No band slippages or band erosion occurred. Resolution or improvement occurred in most obesity-related illness. Gastroesophageal reflux disease symptoms worsened in 25%of patients.ConclusionsThese results replicate world LAGB literature. Low complication rates result either from the authors' band or their techniques.

  • Determinants of Tc-99m sestamibi SPECT scan sensitivity in primary hyperparathyroidism

    Todd W. Swanson   Simon K. Chan   Steven J. Jones   Samuel Bugis   Robert Irvine   Allan Belzberg   Daniel Levine   Sam M. Wiseman  

    BackgroundThe aim of this study was to evaluate the influence of patient and adenoma characteristics on 99mTc–methoxy isobutyl isonitrile (MIBI) scan performance in individuals diagnosed with primary hyperparathyroidism (PHP).MethodsRecords of patients undergoing parathyroidectomy for PHP over 6 years at a single center were reviewed.ResultsThe overall true-positive (TP) rate for 99mTc-MIBI scans was 56%. Adenomas sized 1.9 to 3.5 cm were more likely to have TP scans than 0.3-cm to 1.8-cm adenomas (74%vs 40%, P < .001). Preoperative ionized calcium levels between 1.49 and 1.72 mmol/L were more likely to have TPs than levels between 1.27 and 1.48 mmol/L (65%vs 47%, P < .05). No single class of medication was shown to significantly effect TP rates. A decrease in TP rate was observed for larger adenomas in patients on ≥1 medication (74%vs 65%, P = .05).ConclusionsIn PHP, 99mTc-MIBI scan positivity is most related to adenoma size and preoperative ionized calcium level.

    In organizations, it is often necessary to engage in costly delegation of ideas; such delegation seeks to eciently aggregate multiple information signals. What this paper shows is that those who delegate often nd it impossible to separate the evaluation of the ideas they delegate from the evaluation of the abilities of those who are delegated the task of assessing these ideas. This commingling of the assessment of the idea with that of the individual agent generates a tendency for the agent to ignore his own information and instead attempt to conrm the superior s prior belief. We refer to this as sunower management. Beyond characterizing the eects of sunower management on the delegation process, our analysis also allows us to extract implications of sun- ower management for the use of centralized versus decentralized capital budgeting systems, and to explain why rms may overinvest capital even when managers have no innate preference for empire building .
