Decortication as an Option for Empyema Thoracis.

Abstract

To analyse the outcome and morbidity associated with decortication in empyema thoracis. A case series. Departments of Surgery, Combined Military Hospitals (CMH) of Rawalpindi, Quetta and Lahore, from January 2006 to March 2018. This is a retrospective study of 812 cases of open and VATS (video-assisted thoracic surgery) decortication for empyema thoracis, operated by the same consultants. Only patients with established empyema were included. Those who were unfit for one-lung ventilation, undergoing local anesthesia procedures like rib resection, clagget window or tube windows, with clotted hemothorax and malignant pathology were excluded. Posterolateral serratus sparing thoracotomy was used in open decortications. Multiportal or uniport VATS was employed for video-assisted thoracoscopic decortications (VATD). Histopathology and microbiological sampling was also done in all cases. There were 537 (66.1%) males and 275 (33.9%) females. Age ranged from 1 to 80 years with a mean of 37 years. Open decortication was done in 650 (80%), standard decortication with posterolateral thoracotomy in 458 (56.4%), minithoracotomy was done in 69 (8.4%) patients with loculated empyema, thoracotomy and open decortication with conventional thoracoplasty was done in 21 patients. Twenty-two patients required open decortications with tailored thoracoplasty and muscle flap. Open decortication with intercostal muscle (ICM) flap or primary closure of bronchopleural fistula was performed in 55 patients. VATD was done in 162 cases, out of which 120 were early empyema, and 42 were of chronic empyema; of which 22 required a further utility thoracotomy. Decortication with lung resection and muscle flap reinforcement to bronchial stump was done in 25 patients. Blood transfusion was required in 331 (40.7%). Twenty-six (3.4%) patients developed residual space and collection requiring intervention; and 384 (47.3%) patients had a histopathology diagnostic for tuberculosis. There were 11 (1.3%) deaths. Open decortication is still one of the preferred procedures in developing countries. VATD is also increasingly utilised for empyema.
