Using standard surgical procedures, the surgeon will proceed with the planned laparoscopic surgery. All procedures will be done by straight laparoscopic technique according to standard of care. At the completion of the procedure, and under laparoscopic control, patients will have a TAP block placed by the attending surgeon. The clinical research nurse involved in the research will prep the solution to be injected and the surgeon will be blinded as to whether the patient will be receiving normal saline or Marcaine in the TAP blocks. The block will be administered between the costal margin and iliac crest in the anterior axillary line. A Braun Stimuplex A insulated needle (80 mm 21 gauge) with 0.5 mL/kg solution (max of 30 ml) is passed through the skin, and then continued until two distinct "pops" are felt, which indicates the needle piercing each of the two fascial layers. The needle is then deemed to be in the inter-muscular plane between internal oblique and transversus abdominis muscles respectively, to target the spinal nerves in this plane. The laparoscope will be visualizing for the needle tip to ensure that it does not penetrate the peritoneum or inject pre-peritoneally. The local anesthetic is infiltrated in two separate injections into the same plane on each side. If a sub-peritoneal bleb is seen to be raised by the laparoscope, then the needle will be withdrawn slightly. Two thirds of the solution is injected, and the needle is withdrawn 5 mm and the remaining solution is injected. If injecting in the correct plane, then a smooth raised area of fluid, covered by transversus will be seen via the laparoscope. This procedure is repeated on the patients other side, to complete a bilateral block. Depending on their randomization, patients will receive one of the following solutions:
