Study Objectives:
To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis.
Design:
Retrospective review.
Setting:
Tokyo University Hospital between 2006 and 2013.
Patients:
Four patients among a total of 2814 patients with a postoperative pneumothorax.
Intervention:
Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax.
Measurements And Main 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.
Conclusion:
The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery.
