The LAPTAP trial will provide evidence on preferred post-operative analgesia method in elective laparoscopic colon surgery.


In most previous studies TAP-block has been inserted by anesthesiologist under ultrasound guidance. TAP blockade can alternatively be performed by a surgeon with laparoscopic visual guidance during trocar placement by aiming injection into fascial plane between the internal oblique and transversus abdominis in the midaxillary line and repeated on the contralateral side. There is lack in studies comparing laparoscopic guided TAP-blockade versus epidural pain analgesia in elective laparoscopic colon surgery exist.
