Emphysema is a progressive unrelenting component of chronic obstructive pulmonary disease and a major source of mortality and morbidity globally. The prevalence of moderate to severe emphysema is approximately 5% in Malaysia and likely to increase in the future. Hence advanced emphysema will emerge as a leading cause of hospital admission and a major consumer of healthcare resources in this country in the future. Patients with advanced disease have a poor quality of life and reduced survival. Medical therapy has been largely ineffective for many patients however certain subgroups have disease amenable to surgical palliation. Effective surgical therapies include lung volume reduction surgery, lung transplantation and bullectomy. This article is a comprehensive evidence based review of the literature evaluating the rationale, efficacy, safety and limitations of surgery for advanced emphysema highlighting the importance of meticulous patient selection and local factors relevant to Malaysia.
Simultaneous bilateral spontaneous pneumothorax (SBSP) is a very rare life-threatening condition that requires rapid diagnosis and treatment. Most cases are secondary to various underlying lung pathology but a primary SBSP may occur due to rupture of subpleural blebs or bullae. Surgery via an open or minimally invasive approach provides definitive treatment and can be undertaken as a staged or simultaneous procedure. We report our experience with two such rare cases utilizing a single stage minimally invasive bilateral video assisted thoracoscopic (VATS) approach. The pathogenesis of this rare condition and intra-operative technical considerations for a successful outcome are discussed.
Chronic total occlusion (CTO) of the left main coronary artery (LMCA) is a rare manifestation of coronary artery disease (CAD) and defined by a total absence of antegrade blood flow to the left anterior descending (LAD) and circumflex (Cx) system. Patients are at high risk of myocardial ischaemia as a sizeable area of myocardium is at risk and thus require urgent intervention. Surgery is the treatment of choice especially with CTO lesions as percutaneous coronary intervention has limited success with a high restenosis rate. We report a rare case of a young Chinese male who presented acutely with a myocardial infarction and discuss the aetiology and peri-operative technical considerations for successful surgery with this condition.
Traumatic chest injury with complete tracheo- bronchial disruption is uncommon and occurs in approximately 1% of motor vehicle accidents (MVA) (1,2). Such injuries carry a high mortality and patients rarely survive transfer to hospital. A high index of suspicion facilitates early diagnosis. Early operative intervention is vital for survival. We describe a rare case of traumatic complete disruption of the right mainstem bronchus (RMB) due to blunt chest trauma. The transected airway was reanastomosed emergently avoiding a lung resection.
Emergency lung resection for chest trauma is a rare event with a reported incidence of 0.08-1.3% but is associated with a high morbidity and mortality especially if a pneumonectomy is required, if due to blunt chest trauma or when concomitant injuries are present. We report three cases of young adult males with penetrating chest injuries that required emergency thoracotomy (ET) and anatomical lung resection to achieve definitive control of life threatening pulmonary haemorrhage. All patients survived to hospital discharge and remained well on follow-up. Indications for an ET and what constitutes the optimal operative management of such patients is discussed.
Acute kidney injury (AKI) following cardiac surgery is well established but the reported incidence is variable due to varying definitions and criteria. Furthermore there is a paucity of such data from Southeast Asia.
