ABSTRACT
Background: Since the introduction of 4 trocar laparoscope as a golden standard practiced worldwide, there has been an attempt to possibly reduce the number of trocars to achieve better results. Nowadays the alternative 3 or even 2- port LCs have gained attention due to their potential impact on decreasing post-operative pain, leaving less scars behind and maintaining cosmetic superiority. This study aimed at investigating the superiority of 3 port LCs vs the conventional 4 port ones in terms of their technical feasibility, safety and other benefits
Methods: In this clinical trial study, 100 patients with gall bladder stones admitted at Sina Hospital, in Tabriz from Sep. 2013 to Sep. 2014 were randomly divided into two groups of 50 each; one was treated using 4 port technique and the other by means of 3 port technique. Intraoperative findings and postoperative complications were carefully recorded and analyzed
Results: The two parameters- conversion of surgery and bile duct injury- were nil for both groups. Gall bladder perforation in 3- port group happened to be less than 4-port group [17.50 vs 28.50] that is [P=0.027]. No significant difference was reported on other factors including liver bed bleeding or length of operation
Conclusion: The fact that in port 3 LCs the operating time will not take any longer and complications are no more than those in 4-port LCs proves them technically safe and feasible. additionally 3-port LCs have some postoperative advantages such as less scars and maintained cosmetic superiority
