Does the number of wires used to close a sternotomy have an impact on deep sternal wound infection?
We studied the influence of the number of sternotomy mechanical fixation points on deep sternal wound infection (DSWI). ⋯ DSWI is associated with hypoxia, ischaemia, sepsis and mechanical sternal instability. DSWI may be prevented by using nine or more paired fixation points when closing with standard peri-sternal wires.

ReviewIs radiofrequency ablation more effective than stereotactic ablative radiotherapy in patients with early stage medically inoperable non-small cell lung cancer?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'is radiofrequency ablation more effective than stereotactic ablative radiotherapy in patients with early stage medically inoperable non-small cell lung cancer?' Altogether, over 219 papers were found, of which 16 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. ⋯ RFA is not recommended for centrally based tumours. Patients with small apical tumours, posteriorly positioned tumours, peripheral tumours and tumours close to the scapula where it may be difficult to position an active electrode are more optimally treated with SABR. Treatment for early stage inoperable NSCLC should be tailored to individual patients, and under certain circumstances, a combined approach may be beneficial.

Case ReportsPreservation of systemic tricuspid valve function by pulmonary conduit banding in a patient with corrected transposition of the great arteries.
Systemic tricuspid valve regurgitation increases mortality and morbidity in patients with a corrected transposition of the great arteries. A 17-year old male with a physiologically corrected transposition after the closure of a ventricular septal defect and conduit placement between a morphological left ventricle and pulmonary artery presented with exertional dyspnoea. The transthoracic echocardiography showed a severe conduit stenosis, and cardiac catheterization revealed a pressure gradient of 114 mmHg. ⋯ Pulmonary conduit banding was performed under transoesophageal echocardiography guidance, during which the left ventricular to right ventricular pressure ratio increased from 0.33 to 0.60 and the degree of tricuspid regurgitation decreased mildly. The patient was discharged uneventfully at postoperative day 16. Conduit banding might be a useful technique to preserve the systemic tricuspid valve function during conduit re-replacement in patients with a corrected transposition.

Case ReportsAn unusual cause of acute abdominal pain after cardiac surgery: acute epiploic appendagitis.
Abdominal complications following cardiac surgery remain unusual, but are associated with high mortality. The most common abdominal surgical complications are mesenteric ischaemia, diverticulitis, pancreatitis, gastrointestinal bleeding and cholecystitis. We describe a case of a 73-year old woman with acute abdominal pain mimicking cholecystitis on day 10 after aortic valve replacement. ⋯ Depending on its localization, it mimics many diagnoses requiring surgery: colitis, diverticulitis, appendicitis and cholecystitis. An abdominal CT scan is the diagnostic imaging tool of choice. All physicians involved in post-cardiac surgery care should be aware of this self-limiting disease that usually resolves with non-steroidal anti-inflammatory drugs and watchful waiting, and to avoid unnecessary surgery because the spontaneous evolution of epiploic appendagitis is usually benign.
