Recruitment will be a double-blind, placebo-controlled randomized study in patients age 18 and above going for bariatric surgery. The study will involve two groups with equal allocation of patients in the test group (local anaesthesia) and control group (normal saline) by randomization. All patient will need to be evaluated by our multidisciplinary team before randomization. Each patient going for an elective bariatric surgery will be informed regarding this research study, and the final decision will solely be made based on patients' willingness. All patients who agree to participate in this study will be randomized into one of the study groups. The patients will also be made aware that this is an experimental trial and both verbal and written informed consent will be taken before treatment. In addition, the patients will be informed regarding the use of the clinical and analytical data for publication purposes.
