Introduction and Aims: Empyema thoracis is a pleural space pathology that indicates accumulation of purulent material in the pleural space. It is often associated with an underlying infectious process, such as pneumonia, but can also be a ramification of a more sinister etiology, such as lung carcinoma, often warranting lung decortication surgery for prompt resolution. Although radiological imaging is used to form a preliminary diagnosis, its true predictive value remains questionable, and intraoperative microbiological, cytological, and histopathological samples are thus instrumental in yielding helpful diagnostic information. This study aims to gauge whether intraoperative microbiological, cytological, and histopathological analyses yield any additional diagnostic information in establishing the etiology underlying empyema, necessitating decortication surgery. Methods: Microbiological, cytological, and histopathological records of 43 patients undergoing decortication surgery were included in this study. Only patients who were diagnosed with late stages of empyema and subsequently underwent decortication surgery were included in this study. Results: The sample consisted of 43 patients, including 23 males and 20 females. For microbiology, 4.88% of the bronchoalveolar lavage (BAL) samples, 7.69% of tissue fluid samples, and 7.32% of pleural fluid samples were positive for an infectious microorganism. For cytology/histopathology, 0.00% of BAL samples, 5.41% of pleural fluid samples, and 7.32% of tissue samples were positive for an underlying infective etiology. Conclusion: For the study and analysis of the microbiological samples, a myriad of all three different modalities of diagnosis is essential. However, tissue sampling is the preferred modality of diagnosis for cytology/histopathology owing to its ability to detect positive cases that might otherwise evade prompt detection.
Introduction Oesophago-pleural fistula (OPF) is an infrequent but highly complex complication of pneumonectomy with a mortality of up to 63%. There is a paucity of data on the optimal treatment strategy. Method Systematic review was conducted in line with PRISMA guidance concerning OPF following pneumonectomy. Demographic, operative and management data were analysed. Results 30 full manuscripts of the 76 abstracts were included in the analysis. Data was limited to case reports or small series. In total, information for 58 patients was included. Median age was 59 years, with a median follow up time was 18 months. Most authors adopted sepsis control with chest drainage and pleural lavage and the mean number of interventions was 1.6. Overall mortality was 31% (18/58). There was no significant difference between the time to presentation following left (29.2+/-39.28 months) and right pneumonectomy (66.24+/-110.62) (p = 0.2271) nor any significant difference between successful outcomes following intervention for OPF after left (11/14) compared to right pneumonectomy (31/41) (p = 0.8219) or 90-day mortality (p = 0.4571). However, 26% of patients had synchronous broncho-pleural fistula and 90-day mortality was significantly higher in these patients (6/15 vs 6/43. p = 0.0395). 25 patients who underwent additional pericardial, oesophageal or a nodal resection or intervention at the time of pneumonectomy had a significantly reduced mean time to presentation with OPF (21.49+/-60.15 vs. 84.99+/-114.31. p = 0.0148) and a higher 90-day mortality (8/25 vs 3/32. P = 0.0414). Conclusions Major heterogeneity of management hinders the introduction of standardised guidance of post-pnuemonectomy OPF. An MDT approach involving Oesophago-gastric and Cardio-Thoracic Surgery is vital.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
