A modified laparoscopic entry technique using a finger and rubber catheter

Hasson and Grimes have developed the so-called open laparoscopy technique. Patients with surgical history and obese patients present a higher risk for laparoscopy. Since the development of laparoscopic cholecystectomy general surgeons have been able to obtain instruction in percutaneous and open techniques in various laparoscopic training centers throughout the United States. The percutaneous technique uses the Veress needle, while the open technique uses the Hasson cannula. We present a modification of the open technique using a finger and rubber catheter to thread the trocar cannula into the abdomen using standard disposable cannulas and avoiding the use of the Hasson cannula.
