['Decortication for thoracic empyema is associated with significant blood loss and prolonged postoperative air leak. We sought to assess the potential application of an irrigated-tip radiofrequency (RF) sealing device, in an attempt to reduce this morbidity.', "Data for all patients undergoing open decortication (OD) for stage II thoracic empyema, using either conventional approach or facilitated by use of the Aquamantys(®) device, at a single thoracic surgical unit between April 2010 and July 2014, were retrospectively analysed. Unpaired t-test and Fisher's exact test were used for statistical analysis.", 'Thirty-three patients, aged 54±15 years (mean ± SD), and with a Charlson comorbidity index of 2.5±1.9 were included. Preoperative and intraoperative characteristics, including surgical time, were similar in the conventional and Aquamantys(®) groups. Patients in the Aquamantys group were less likely to require red cell transfusion (9/22 vs. 10/11 patients, P=0.024) and received lower volume transfusions [0.0 (2.0) vs. 3.0 (1.6) units (median, IQR), P<0.0001]; chest drain duration was shorter [3.0 (1.0) vs. 6.5 (6.8) days, P=0.006], as was length of postoperative hospital stay [6.0 (8.7) vs. 10.0 (4.6) days, P=0.031]. There was no demonstrable difference in mortality.'] Does the Aquamantys ( ® ) system improve haemostasis and pneumostasis in open decortication for thoracic empyema?
