RESUMO
BACKGROUND: Complications following esophagectomy are a significant source of morbidity. The aim of this study was to investigate the utility of the neutrophil:lymphocyte ratio (NLR) in the early identification of complications following esophagectomy, as compared to other routinely available parameters. METHODS: We performed a retrospective cohort study of patients undergoing Ivor-Lewis esophagectomy at a single centre. Baseline characteristics and complications occurring within the first 30 days of surgery were recorded. White blood cell counts and C-reactive protein (CRP) levels immediately following surgery (day 0) and over the subsequent three postoperative days were analysed. RESULTS: Sixty-five patients were included, of whom 29 (45 %) developed complications. The median NLR was similar among patients with and without a complicated recovery on day 0 (12.7 vs 13.6, p = 0.70) and day 1 (10.0 vs 9.3, p = 0.29). Patients who subsequently developed complications had a higher NLR on day 2 (11.8 vs 7.5, p < 0.001) and day 3 (9.0 vs 6.5, p = 0.001) compared to those whose recovery was uncomplicated. Receiver-operating-characteristic plots for the diagnostic performance of the NLR, neutrophil count, lymphocyte count and CRP level at each time point demonstrated that the NLR on day 2 had the greatest discriminatory ability in predicting complications, with an area under the curve of 0.83 (95 % CI 0.73-0.94). An NLR of >8.3 on day 2 had a sensitivity of 93 % and a specificity of 72 % for predicting complications. CONCLUSION: The NLR is a simple and routinely available parameter which has a high sensitivity in the early detection of complications following esophagectomy.

Open fractures incur significant morbidity and mortality, and as such have standardised guidelines for their management. Photography of open fractures is an essential component of documentation in the treatment of open fractures as per the British Orthopaedic Association Standards of Trauma and National Institute for Health and Care Excellence guidelines. Smartphones have made photography easily accessible to the clinician, but serious concerns exist regarding data security and the consent process around the use of sensitive clinical images. This project sought to overcome this issue by developing a Caldicott-compliant hospital imaging protocol that allows clinicians to use their smartphone to upload open fracture images into the patient's permanent record. Implementation of the protocol was audited and resulted in the increase of safe and secure open fracture photographic storage to inpatient medical records. This protocol would be transferrable to other hospital trusts and could be adopted across major trauma networks.
