Outcomes and complications following medical thoracoscopy
MetadataShow full item record
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.

Franklin, P.; Alfonso, H.; Reid, A.; Olsen, N.; Shilkin, K.; Brims, Fraser; de Klerk, N.; Musk, A. (2016)Background: Malignant mesothelioma (MM) has distinct histological subtypes (epithelioid, sarcomatoid and biphasic) with variable behaviour and prognoses. It is well recognised that survival time varies with the histological ...

(2015)Malignant peripheral nerve sheath tumors (MPNSTs) are highly aggressive soft-tissue sarcomas, characterized by complex karyotypes. The molecular bases of such malignancy are poorly understood and efficient targeted molecular ...

(2017)Background: Survival with the epithelioid subtype of malignant mesothelioma (MM) is longer than the biphasic or sarcomatoid subtypes. There is concern that cytology-diagnosed epithelioid MM may underdiagnose the biphasic ...
