Introduction:Elective Laparoscopic Cholecystectomy (LC) is an ambulatory or day care surgery. Postoperative morbidity can prolong hospitalisation upsetting the fasttrack clinical pathways.We studied the impact of using surgical energy (USE) in LC on existing fasttrack LC clinical pathway protocols.

METHODS AND PROCEDURES -An open ended triple blind randomized study of consecutive unselected consenting LC candidates for standard ambulatory (discharge ability < 4hours) clinical pathway protocol. Randomization by external research coordinators ( blind to peri-operative observations) into Group A and Group B. Standard techniques of LC with / without USE followed by surgeons (blind to pre-postoperative parameters / observations) for the group allocated. The data being collected by blinded non-operative research coordinators & stored online in auto-locking Hospital Information System (HIS). Prospective data will be analyzed at completion.
