Uniportal Thoracoscopic Decortication for Stage III Tuberculous Empyema With Severe Rib Crowding.

BACKGROUND

This study explored the safety and feasibility of uniportal video-assisted thoracoscopic (VATS) decortication in patients presenting with stage III tuberculous empyema with severe rib crowding.

METHODS

From August 2017 to January /2019, 33 patients with stage III tuberculous empyema and severe rib crowding underwent uniportal VATS decortication with partial rib resection and the use of a customized periosteal stripper. Preoperative and postoperative chest computed tomography (CT) imaging and pulmonary function testing were analyzed to evaluate the clinical significance of certain imaging findings and surgical efficacy.

RESULTS

There was 1 conversion to open thoracotomy. Median operative time was 3.5 hours (range, 2.1-4.5 hours) and the median blood loss was 500 mL (range, 250-1000 mL). There were no perioperative mortalities. The incidence of prolonged air leaks (>5 days) was 81.8%. Median postoperative hospital stay was 4 days (range, 4-5 days). All patients were discharged with 2 chest tubes, and median duration drainage was 39 days (range, 30-60 days). The presence of a low-density line between the parietal fibrous pleural rind and chest wall was demonstrated on chest CT in 13 patients. Intraoperative blood loss was considerably lower in these patients compared with those without this imaging finding. Follow-up was complete in all patients over a median of 8 months (range, 6-11.5 months). All patients recovered well and achieved notable improvement in pulmonary function.

CONCLUSIONS

Uniportal VATS decortication is safe and effective. Patients presenting with a low-density line around the thickened fibrous pleural rind on preoperative chest CT scan may be good candidates.
