Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to assess the size and location of cutaneous sensory block area after dual laparoscopic assisted transverse abdominis plane block (L-TAP) with ropivacaine in patients undergoing laparoscopic cholecystectomy.

L-TAP is applied as a medial subcostal infiltration between midclavicular and central sternal lines and a lateral subcostal infiltration between midclavicular and anterior axillary line bilaterally.
