For direct laparoscopic entry using a sharp and dull trocar technique, the sharp trocar is inserted with a twisting motion under constant pressure, then replaced with a dull trocar when a slight loss of resistance is felt. A slow, gradual entry into the peritoneal cavity is accomplished by twisting the dull trocar under constant pressure. Previous major abdominal or pelvic surgery is not a contraindication to this procedure, and use of these trocars, which can be resterilized for every use, may reduce surgical costs by decreasing the need for disposable trocars. This technique has been used in 1655 patients without complication or failure.
