Computer generated randomization will be done using Interactive Web Response Technology. There will be equal chances for patients to be assigned to either one of the study groups. The result of the randomization will be kept in envelopes and viewed by the research assistant who did not otherwise participate in this study, were unknown to the investigators and the patients, and the answer will be contained in a set of sealed envelopes. After admitting the patient into the operating room and just before the surgery was done, the numbered envelope will be opened by the operating theater nurse and the card inside determined which group the patient would be placed. The operating theater nurse will then prepare either 20mL of 150mg ropivacaine in 180mL normal saline (for test group) or 200mL normal saline (for control group) using a standard syringe and the syringe will be given to the surgeon who then injects the solution through a catheter along the greater curvature and left subdiaphragmatic region of the stomach. The general anesthetic used for all patients will be a combination of 1gm IV Paracetamol, 40mg IV Parecoxib and IV Fentamyl prepared according to patient's adjusted body weight.
