Randomized comparison of the effect of manipulation on incisional parameters associated with a pyramidal laparoscopic trocar-cannula system and the EndoTIP cannula.

We conducted a randomized, controlled trial to evaluate the effect of laparoscopic access cannula manipulation on fascial and incisional characteristics in a white swine model, comparing a pyramidal trocar-cannula system (PTC) and a trocarless threaded cannula (TTC, EndoTIP). We made 6 insertions in 10 animals. Cannulas randomized to the movement group were manipulated in standard fashion in skin and subcutaneous tissues.

Intraabdominal pressure and incision parameters associated with a pyramidal laparoscopic trocar-cannula system and the EndoTIP cannula.

Study Objective: To compare intraabdominal pressure and incision characteristics associated with insertion of a disposable pyramidal trocar-cannula system (T-CS) and the EndoTIP threaded cannula, a trocarless, reusable laparoscopic access device.

Design: Randomized trial (Canadian Task Force classification I).

Subjects: White swine.
