Four Cases of Postoperative Pneumothorax Among 2814 Consecutive Laparoscopic Gynecologic Surgeries: A Possible Correlation Between Postoperative Pneumothorax and Endometriosis.
OBJECTIVE
To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis.


METHODS
Retrospective review.


METHODS
Tokyo University Hospital between 2006 and 2013.


METHODS
Four patients among a total of 2814 patients with a postoperative pneumothorax.


METHODS
Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax.


RESULTS
We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas.


CONCLUSIONS
The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery.
