During the TLIP block, block fluid will have total volume of 20 mL of 0.5% bupivacaine.). In Group E, after surgery, total of 20 ml of 0.1% bupivacaine and 50 mcg of fentanyl will be performed in the epidural space with direct vision by the surgeon.For the postoperative analgesia, patient controlled analgesia device will be administered as 20 mg/h continue dose tramadol and administered 10 mg bolus dose tramadol if patient need a rescue dose.
