  Purpose

Keyhole surgery for adnexal disease has traditionally been performed using three or four small incisions. The last years a new operating method has been introduced. This method makes use of only one incision of 2 cm in the umbilicus. This method is less invasive, and it might benefit the patient through less postoperative pain and a higher satisfaction with the cosmetic result. So far, many studies have shown that this new method is feasible for adnexal disease, but its superiority compared to conventional laparoscopy is to be proven. This study aims to show this difference.

The investigators aim to compare experienced postoperative pain and use of analgesics in patients undergoing single port laparoscopy for benign adnexal disease with conventional laparoscopy. The investigators hypothesize that the patients will experience less postoperative pain and use less analgesic in the single port laparoscopy group.

Further, the investigators aim to compare the satisfaction with the cosmetic results in the two groups. In addition, blood loss, operating time, complications and conversion to conventional laparoscopy will be registered in the two groups.
