A new mechanical suturing device called Fasterzip was used in three groups of patients of both sexes undergoing surgery for cholelithiasis, inguinal hernia and appendicitis. The use and removal of the device was very fast and easy. Clinical controls were performed 3, 8, 30, 60 and 90 days after surgery. In all cases, the scarring process took places in a physiological manner and resulted in the healing of the skin wound with excellent results from a cosmetic point of view.
