Patients undergoing laparoscopic cholecystectomy were separated into 3 groups. Group 1: Received TAP block Group 2: Received OSTAP Group 3: No Block Standard General Anesthesia was induced and maintained in all patients. At the end of the operation patient controlled analgesia with morphine was applied to all patients.~Pain scores were evaluated at 0,2,4,6,12,24 hours postoperatively.

The aim of the study is to compare the effectiveness and opioid sparing effects of TAP and OSTAP in patients undergoing laparoscopic cholecystectomy.
