Dislodged Laparoscopic Cannulas
In very thin patients with a thin abdominal wall, avoiding cannula slippage can be challenging as the subcutaneous tissues help hold the trocar in place. In addition, significant amounts of torque placed on the trocar during the operation can increase the size of the fascial defect. When the cannula slips out, it can be difficult to find the original tract to re-place it. This problem can add time to the surgery and can be frustrating when it occurs repeatedly. In this chapter we will review methods to help with avoiding or managing dislodged cannulas.
