The impact of operative approach on outcome of surgery for gastro-oesophageal tumours

<p>Abstract</p> <p>Background</p> <p>The choice of operation for tumours at or around the gastro-oesophageal junction remains controversial with little evidence to support one technique over another. This study examines the prevalence of margin involvement and nodal disease and their impact on outcome following three surgical approaches (Ivor Lewis, transhiatal and left thoraco-laparotomy) for these tumours.</p> <p>Methods</p> <p>A retrospective analysis was conducted of patients undergoing surgery for distal oesophageal and gastro-oesophageal junction tumours by a single surgeon over ten years. Comparisons were undertaken in terms of tumour clearance, nodal yield, postoperative morbidity, mortality, and median survival. All patients were followed up until death or the end of the data collection (mean follow up 33.2 months).</p> <p>Results</p> <p>A total of 104 patients were operated on of which 102 underwent resection (98%). Median age was 64.1 yrs (range 32.1–79.4) with 77 males and 25 females. Procedures included 29 Ivor Lewis, 31 transhiatal and 42 left-thoraco-laparotomies. Postoperative mortality was 2.9% and median survival 23 months. Margin involvement was 24.1% (two distal, one proximal and 17 circumferential margins). Operative approach had no significant effect on nodal clearance, margin involvement, postoperative mortality or morbidity and survival. Lymph node positive disease had a significantly worse median survival of 15.8 months compared to 39.7 months for node negative (<it>p </it>= 0.007), irrespective of approach.</p> <p>Conclusion</p> <p>Surgical approach had no effect on postoperative mortality, circumferential tumour, nodal clearance or survival. This suggests that the choice of operative approach for tumours at the gastro-oesophageal junction may be based on the individual patient and tumour location rather than surgical dogma.</p

Use of a Javid™ shunt in the management of axillary artery injury as a complication of fracture of the surgical neck of the humerus: a case report

<p>Abstract</p> <p>Introduction</p> <p>Axillary artery injury is a rare but severe complication of fractures of the surgical neck of the humerus.</p> <p>Case presentation</p> <p>We present a case of axillary artery pseudoaneurysm secondary to such a fracture, in a 82-year-old white woman, presenting 10 weeks after the initial injury, successfully treated with subclavian to brachial reversed vein bypass together with simultaneous open reduction and internal fixation of the fracture. We discuss the use of a Javid™ shunt during combined upper limb revascularisation and open reduction and internal fixation of the fractured humerus.</p> <p>Conclusion</p> <p>This case highlights the usefulness of a Javid™ shunt, over other forms of vascular shunts, in prompt restoration of blood flow to effect limb salvage. It can be considered as a temporary measure whilst awaiting definitive revascularisation which can be performed following fracture fixation.</p

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

Are Brain Natriuretic Peptide Levels Related to Flow through Autologous Aterio-Venous Fistulae for Chronic Haemodialysis?

Formation of arterio-venous-fistulae (AVF) may exacerbate cardiac failure in the ever increasing, elderly population on haemodialysis. Brain Natriuretic Peptide (BNP) may prove a useful marker of cardiac failure in this population. We aimed to determine effect of creation of an AVF and flow in AVF on BNP levels. Ten patients undergoing primary formation of an upper limb autologous AVF (pre-dialysis), were recruited. Serum BNP (pg/ml) and flow in AVF (cm3/s) were documented pre-operatively, and then 2, 6 and 12 weeks post-operatively. The relationship between flow and BNP levels was assessed. Ten patients (6 male), mean age of 66yrs were recruited. Five patients had a radio-cephalic and 5 had a brachio-cephalic AVF formed. There was no correlation between BNP levels and flow within the AVF (r=0.34, p=0.28) at any time point. There was a general trend towards increased flow in the AVF over time, with only the change between flow at 2-weeks and 3-months postoperatively reaching significance, p=0.043. There was a general trend for BNP to fall over time in the postoperative period, with no significant change between the postoperative sampling time points. BNP levels do not correlate with flow across an AVF
