Accuracy of after-hours trauma cervical spine CT reporting by radiology trainees: Experiences from two Australian teaching hospitals.

INTRODUCTION: Like many teaching hospitals in Australia, after-hours computed tomography (CT) reporting at our institution is undertaken by the on-call radiology registrar. The accuracy of these reports is important as management is often initiated based on the interim findings, prior to review by the consultant radiologist. A common exception to this approach is cervical CT (CCT), as many hospital protocols recommend patients to remain in spinal precautions until the report is finalised by a consultant, although there are very few studies to support this practice. METHODS: The interim registrar reports for all CCTs performed after-hours over a 12-month period were retrospectively reviewed. The final consultant report was used as the gold standard to establish accuracy of the registrar report. The primary outcome was discrepancy between the provisional and final reports. Any discrepancy was classified as either an 'overcall' or 'miss'. Discrepancies were graded by the RADPEER scoring system. RESULTS: A total of 1084 after-hours CCT studies were reviewed. The number of cases positive for injury was 37 (3.4%). The total number of discrepancies was 14 (discrepancy rate 1.3%), including 4 overcalls (0.3%) and 10 misses (0.9%). The discrepancy rates for junior and senior registrars were 1.7% and 0.7% respectively. Only 5 misses (0.5%) were considered clinically significant. CONCLUSION: Registrars reporting after-hours CCT have low rates of discrepancy with very few clinically significant misses. However, the reduced registrar sensitivity for detection of cervical injury highlights the ongoing importance of consultant review in the process of cervical spine clearance pathways.

Laparoscopic Adjustable Gastric Banding In Patients with Unexpected Cirrhosis: Safety and Outcomes.

BACKGROUND: The safety and efficacy of laparoscopic adjustable gastric banding (LAGB) in the context of cirrhosis have not been established. We hypothesized that LAGB in cirrhotic patients is a safe procedure that may offer positive long-term benefits, both in terms of obesity and avoiding progression of liver disease. METHODS: Data were gathered from a prospectively maintained database of 8402 patients who had undergone LAGB from November 1993 and April 2014. RESULTS: Fourteen patients with biopsy-proven cirrhosis were identified in the database. In all cases, cirrhosis was an unexpected macroscopic finding at the time of surgery, confirmed with intraoperative biopsy. All patients were either Child-Pugh A or B. No patients had preoperative clinical evidence of decompensated liver disease. The mean initial weight was 116.6 kg and BMI 38.9. There was no operative mortality. Two patients experienced a surgical complication (Clavien-Dindo grade II and grade IIIa). At 12 months, the mean excess weight loss was 61.3% giving a mean BMI 31.7. Repeat biopsies were available in three patients. All demonstrated improvement in inflammation and two had fibrosis regression. Baseline liver biochemistry was compared in nine patients who had repeat biochemistry studies after 12 months. There was a significant improvement in alanine transaminase (ALT) (p = 0.04) and aspartate transaminase (AST) (p = 0.02). Two patients developed hepatocellular carcinoma (HCC). One has died as a result of this disease 11 years after LAGB surgery. CONCLUSION: LAGB may be a safe and effective bariatric intervention in patients with compensated cirrhosis. Our findings support the need for a prospective study with paired liver biopsies.
