| Summary: | To discuss the aetiology and determine the optimal surgical treatment of catamenial pneumothorax.
Methods: Between January 1980 and December 2007, 17 patients with catamenial pneumothorax were treated at our institution. Regarding the surgical approach, thoracotomy was performed until 1991, and thoracoscopic surgery was performed from 1992 onward.
Results: Pneumothorax was on the right side in all but two patients. Surgery was performed on 15 of the 17 patients. The surgical procedure was a diaphragm resection plus a partial bleb resection in eight patients, a diaphragm resection in two patients, a diaphragm resection plus an absorbable polyglycolic acid sheet in four patients, and a partial bleb resection in one patient. Five patients demonstrated a postoperative recurrence (33.0%). However, no recurrence has been observed thus far in the four patients with an absorbable polyglycolic sheet placed on the diaphragmatic surface.
Conclusion: Although the postoperative recurrence rate of patients undergoing surgical procedures remains high, there were some patients with no postoperative recurrence. Placement of an absorbable sheet on the diaphragmatic surface may therefore prevent recurrence of catamenial pneumothorax.
