Active Comparator: Ropivacain
Ropicacain 3,75 mg/ml 15 ml x 4 when placing the Bilateral Dual Transverus Abdominis Plane block
Drug: Ropivacaine
Ropicacain 3,75 mg/ml 15 ml x 4 when placing the Bilateral Dual Transverus Abdominis Plane block
Placebo Comparator: Isotonic potassium chloride

Detailed Description:

After randomisation patients for robotic assisted laparoscopic surgery will receive bilateral dual transversus abdominis plane block containing either ropivacain or isotonic potassium chloride.

The investigators will record pain-score, opioid-consumption and sensibility on the abdominal wall in the postoperative periode.

Also a blood sample will be taken at 15, 30, 60, 120 and 240 minutes after the block in order to measure the plasma-level of ropivacain after bilateral dual transversus abdominis plane block.

The investigators assume that there will be significant effect on postoperative pain and that the level of plasma-ropivacain will be acceptable.
