At the end of the surgery, without waking the patient, a linear transducer will be placed on the costochondral angle in the sagittal plane under ultrasound guidance, and a total of 40 mL of LA (0.25% Bupivacaine) will be applied bilaterally to the lower surface of the chondrium, giving a deep angle to see the lower side of the chondrium centrally.

At the end of surgery, infiltration analgesia will be applied by the surgeon to all trocar entry sites (4 port entries) with 10 ml of 0.25% bupivacaine (40 mL in total) without waking the patient.

M-TAPA block will administer ultrasound guided (Sonosite, Inc., Bothell, WA, USA) bilaterally by same anesthesiologist (E.E.) who had more than 10 years experience of regional anesthesia, before weaking from general anesthesia after the surgical procedure. A high-frequency (6-13 MHz) linear probe (HFL38) will be used to identify the transversus abdominis, internal oblique, and external oblique muscles on the costochondral angle in the sagittal plane at the 10th costal margin. In the midclavicular line, between the upper fascia of the transversus abdominis muscle and the lower fascia of the costochondral tissue, at the level of the 10th rib, 20 mL of 0.25 percent bupivacaine will be injected (arcus costarum). The same procedure will be followed on the other side.

The intravenous PCA pump will be programmed to deliver a bolus of 20 mg tramadol with a lockout interval of 30 min and no baseline infusion (tramadol 500 mg in 100 mL SF

Pain will be assessed with visual analog score (VAS) in 2 different ways, at rest and with movement (VAS: 0, no pain; 10, worst pain imaginable). VAS scores will be recorded at postoperative 0 (PACU), 1, 2, 4, 8, 12 and 24 hours
