We describe a simple method of fixing trocars to the abdominal wall in infants and children using small pieces of 16-or 18-Fr Foley catheter as a sleeve over the trocar. The sleeve holds the trocar snugly and is fixed to the skin with silk stitch. This technique is simple, quick, efficacious, and inexpensive, and it does not require any special equipment and can be used with any trocar size.
