Aim: To evaluate safety and efficacy of harmonic scalpel in closure/division of the cystic duct and artery, and bladder dissectionin laparoscopic cholecystectomy as a single working instrument, with the use of two working trocars, compared with clip/cautery,three trocars technique. Method: A prospective study included 160 patients with symptomatic gall stone disease were randomly assigned for laparoscopic cholecystectomy by either harmonic shear, with two trocars (group I=80 patients), or group II (clip/cautery, 3 trocars) including 80 patients. Results: No significant complications were encountered in either group; however 1 case of group II suffers mild leakage treated conservatively. Intra-operative bile spillage was insignificantly lower in group I (10% vs. 13%; P=0.46). The median operative time was significantly shorter in group I (20 vs. 45 minutes; P=0.0001). Also hospital stay was significantly shorter in group I (1 vs. 1.5 days; P=0.001), but no significant difference found in the incidence of post operative complications. The overall cosmetic results and patient satisfaction was better in group I. Conclusion: Harmonic shear is as safe and effective as clip/cautery technique in achieving hemo-biliary stasis; with shorter operative time especially if used solely as a working instrument. Two trocars technique is safe, feasible, and provides better cosmetic results and patient satisfaction.
