title: Comparison of the Abdominal Wall Stability of Endopath Optiview with the Standard Laparoscopic Cannula
abstract: We conducted a prospective trial to compare the intraabdominal wall stability of the sheath of the Endopath Optiview with that of a conventional reusable cannula. In 100 consecutive women undergoing elective laparoscopic sterilization in an ambulatory surgical unit, we alternately used a standard reusable 10-mm cannula (group A) or the Optiview 10- to 12-mm cannula (group B) to establish the intraabdominal surgical port. Single-incision bipolar laparoscopic tubal occlusion was performed, and the force required to remove the cannula sheath from the abdominal cavity was determined by spring-loaded force gauge. The mean (&plusmn; SEM) peak force required to remove the cannula sheath in group A was 2.25 &plusmn; 0.19 lbs. The comparative value for group B was 5.32 &plusmn; 0.28 lbs. (p <0.005). The in situ operative sheath of the Endopath Optiview has greater intraabdominal wall stability than a standard reusable cannula.
