The goal of this randomized controlled trial is to compare laparoscopic guided peri-wound Transversus Abdominis Plane Block and bupivacaine versus local wound infiltration effect on reducing post-op opioid use in Laparoscopic Sleeve gastrectomy. The main questions it aims to answer are: • Can laparoscopic guided peri-wound Transversus Abdominis Plane Block reduced post operative morphine usage when comparing with local wound port site infiltration. Participants will be randomize into 2 group * peri-wound Transversus Abdominis Plane Block * local wound port site infiltration

0.25% bupivacaine 20ml was injected using no24 needle into a plane between internal oblique muscle and transversus abdominis muscle around every wound 2 cm. from wound opening. The procedure was confirmed by laparoscopic vision and the injection was done before removal of laparoscopic port.
0.25% bupivacaine 20ml was injected using no24 needle into subcutaneous tissue after the abdominal sheet was sutured.
