Plain-language summary

The Transversus Abdominis Plane Block (TAP) has become one of the most established and frequently performed trunk wall blocks for perioperative analgesia in abdominal surgical procedures. The TAP-Block can be performed by both surgeons and anaesthetists. The goal of this prospective, randomized study is to compare an anesthesiological, ultrasound-guided "Transversus Abdominis Plane (TAP) Block" with a laparoscopic, landmark-based "Transversus Abdominis Plane (TAP) Block" The main questions it aims to answer are: Primary Hypothesis: There are no differences in postoperative pain perception and analgesic requirements between the anaesthesiological ultrasound-guided and the surgical laparoscopic landmark-based TAP block Secondary Hypothesis: There are no significant differences in the duration of the procedure between the anaesthesiological, ultrasound-guided and the surgical laparoscopic landmark-based TAP block.
