Novel Lung Biopsy Surgical Technique for Definitive Diagnosis of Pulmonary Capillary Hemangiomatosis.

Purpose: The 2015 European Society of Cardiology/European Respiratory Society Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension state that lung biopsy is still the gold standard for confirming pulmonary capillary hemangiomatosis; however, the surgical lung biopsy is no longer recommended in most cases for its inherent risks. Nonintubated and uniportal video-assisted thoracoscopic surgery are the new developments in video-assisted thoracoscopic surgery technology. We combined these 2 technologies to create a novel approach for pulmonary capillary hemangiomatosis lung biopsy.

Description: A incision is made in chest wall. Sponge forceps are used to pull the lung out of the pleural space, and to resect target lung tissue. The incised margin is sutured with 3-0 Prolene (Ethicon, Somerville, NJ), and a negative pressure suction tube is used to fully expand the lung.

Evaluation: Three patients were definitively diagnosed with pulmonary capillary hemangiomatosis by this technology. One patient developed a postoperative fever, with no other complications.

Conclusions: The tubeless and uniportal video-assisted thoracoscopic surgery lung biopsy is a safe, effective, and feasible technology for definitively diagnosing patients with pulmonary capillary hemangiomatosis.
