A case of deep laceration of the lung treated with video-assisted thoracic surgical lobectomy: case report

Blunt chest trauma with deep pulmonary laceration

BACKGROUND

Deep pulmonary laceration (DPL) is rare and its survival rate is low. The present study focused on the prognostic factors of DPL.

METHODS

The present study concerned 17 DPL patients treated in Tokai University Hospital between 1988 and 1998. The prognostic factors of DPL were compared with systolic blood pressure (SBP), PaO2, and the volume of intrathoracic blood loss. Characteristic findings of initial chest roentgenograms of DPL were investigated.

RESULTS

Eleven patients were saved and 6 patients died. An SBP of less than 80 mm Hg on arrival at the hospital and a blood loss of more than 1,000 mL through the chest tube within 2 hours after arrival were poor prognostic factors. Hypoxemia on arrival was not a poor prognostic factor. Chest roentgenograms showed macular infiltrative shadow with moderate lung collapse and deviation of the mediastinal shadow toward the unaffected side. Selective bronchial occlusion with a Univent prevented suffocation by intrabronchial blood.

CONCLUSIONS

Two poor prognostic factors of DPL are SBP less than 80 mm Hg on arrival and blood loss of more than 1,000 mL through the chest tube within 2 hours after arrival.

Advances in the diagnosis and treatment of thoracic trauma

With the exception of the use of ECG to screen patients for blunt cardiac injury, recent advances in the diagnosis of thoracic trauma involve new technology. Use of surgeon-performed pericardial and pleural ultrasound for the detection of tamponade or hemothorax, TEE or spiral CT to diagnose rupture of the thoracic aorta, and thoracoscopy to evaluate a hemothorax or the integrity of the left hemidiaphragm are all standard techniques in modern trauma centers. In terms of treatment, emergency center thoracotomy is performed more selectively and with the adjunct of staple closure for cardiac wounds. Pulmonotomy is used selectively to control deep lobar hemorrhage and to avoid the need for an emergent lobectomy. Finally, nonoperative management of an intimal tear of the thoracic aorta or delayed operative management of a full-thickness tear in the patient with multiple injuries, using beta-blocker-induced relative hypotension, is rapidly becoming the standard of care throughout the United States.

A prospective evaluation of video-assisted thoracic surgery for persistent air leak due to trauma

BACKGROUND

The time required for air leak resolution after chest trauma is not well described. Based on an institutional review of posttraumatic air leaks our hypothesis was that video-assisted thoracic surgery (VATS) for persistent posttraumatic air leak would decrease chest tube days and length of stay compared with nonoperative management.

METHODS

Patients were offered VATS versus nonoperative management when air leaks persisted longer than 3 days and the patients were otherwise ready for discharge. Chest tube days and length of stay were recorded.

RESULTS

Of 223 trauma patients requiring chest tubes, 50 had persistent air leaks, 39 of whom were otherwise ready for discharge. Twenty-five chose VATS and 14 nonoperative (NOP) treatment. The mean chest tube days was 8.1 for VATS versus 11.8 for NOP (P = 0.001). Mean length of stay was 9.7 days for VATS and 16.5 days for NOP (P = 0.002).

CONCLUSIONS

In patients otherwise ready for discharge VATS reduces chest tube days and length of stay when used to treat persistent posttraumatic air leak.

Video-assisted thoracic surgery (VATS) lobectomy: the Japanese experience

Between September 1992 and October 1997, we performed 128 video-assisted thoracic surgery (VATS) lobectomies. The indications for surgery were 103 cases of lung cancer, 11 cases of bronchiectasis, 8 cases of granuloma, 4 cases of benign lesions, and 2 cases of metastatic tumors. Of the 103 cases of lung cancer, 62 were treated by VATS lobectomy with extended lymph node dissection for clinical stage I lung cancer, and the 4-year survival rate of final stage I lung cancer was 94.4%. VATS lobectomy is far less invasive than open thoracotomy, and survival rates after VATS lobectomy with extended lymph node dissection are comparable with those after open thoracotomy. Thus, VATS lobectomy with extended lymph node dissection should be considered as a standard surgical alternative to open thoracotomy for stage I lung cancer.
