Outcomes and complications following medical thoracoscopy

Introduction: Thoracoscopy is an invasive procedure that may be performed by physicians for the investigation of exudative pleural effusion using local anaesthesia, conscious sedation and a rigid thoracoscope. Objectives: We sought to evaluate the safety and outcome of thoracoscopy in Portsmouth Hospitals, UK, a dockyard city with high previous asbestos usage. Methods: Retrospective casenote, radiology and laboratory result analysis of patients undergoing thoracoscopy in our institution over a 12‐month period. Results: Fifty‐seven of 58 casenotes were available for analysis. Median (interquartile range) age was 73.0 (66.5–79.0) years and 44 (77.2%) were male. Median time with chest drain post‐procedure was 3.0 (2.0–5.0) days, and length of stay (LOS) was 4.0 (2.0–8.0) days. Malignant histology was reported in 40 (70.2%), with 25 (62.5%) cases of mesothelioma. There were no deaths related to the procedure. Hospital‐acquired infection (HAI) occurred in six (10.5%: pneumonia four, empyema two), all had malignancy. The presence of HAI significantly prolonged the LOS 9.0 (7.5–23.5) vs no HAI 4.0 (2.0–7.0) days; P = 0.006). Four patients died within 1 month of the procedure, three had a malignant diagnosis, all had suffered HAI. Trapped lung (persistent hydropneumothorax 5 days post‐procedure) occurred in 11 (19.2%), six of whom had benign histology. Performance status (European Cooperative Oncology Group) prior did not differ with reported histological type: benign 2.0 (2.0–2.0), malignant 2.0 (2.0–3.0), P = 0.170. Conclusions: Serious complications following thoracoscopy are rare. HAI is associated with malignancy and prolonged hospital stay. Benign histology may still confer significant morbidity.
