ABSTRACT Background: The benefits from traditional video-laparoscopic surgery may be improved through techniques increasingly less invasive, which reduce the parietal aggression and the risk of complications due to trocars. Objective: To communicate a case of laparoscopic cholecystectomy with a single trocar at the umbilica scar level and the assistance of magnetic surgical device, for the treatment of vesicular lithiasis. Place of treatment: Clinic of the Trinity-Mitre, Buenos Aires Autonomous City. Population: Report of one case. Results: This technique was performed on a patient having been diagnosed symptomatic vesicular lithiasis. Morbidity: 0%. Mortality: 0%. 24 hours of hospital stay. Optimum aesthetic results. A one month follow up period. Conclusion: With the aid of magnetic surgical devices, we have succeeded on performing traction and counter-traction of the gallbladder, to carry out the cholecystectomy with a single trocar, reproducing the steps of the traditional laparoscopic cholecystectomy. We believe that these devices will be of great help at the time of performing «non scar surgeries». REFERENCES Gagner GM, García-Ruiz A.
