title: One, two, or three ports in laparoscopic cholecystectomy?
abstract: Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data.
