Pneumoperitoneum for the management of pleural air space problems associated with major pulmonary resections.
BACKGROUND
The use of pneumoperitoneum to treat prolonged air leaks or space problems, or both, after pulmonary resection has been recently resurrected and used successfully.


METHODS
During the last 3 years, 14 patients experienced short-term pleural space problems associated with prolonged air leaks after pulmonary resection for lung cancer. All patients, under sedation and local anesthesia, had a mean of 2,100 mL of air injected under the diaphragm, using a Veres needle after a mean time of 7 days (range, 5 to 10 days) from the operation. In 3 patients talc slurry was added to help control the air leak.


RESULTS
No patients experienced complications during the induction of the pneumoperitoneum. No patients complained of dyspnea, although blood gas analysis showed a slight increment of carbon dioxide partial pressure (p < 0.0004). Obliteration of the pleural space was observed in all cases after a mean time of 4 days (range, 1 to 7 days). Air leaks stopped in all patients after a mean time of 8 days (range, 4 to 12 days). The mean postoperative hospital stay after lung resection was 18 days (range, 14 to 22 days). No patients had significant complications or long-term sequelae. We found that patients who had undergone induction chemotherapy had longer air leak durations than observed in noninduction patients (p = 0.03).


CONCLUSIONS
Our experience supports the use of postoperative pneumoperitoneum whenever a space problem associated with prolonged air leaks is present. The procedure is effective, safe, and easy to perform.
