Abstract

BACKGROUND AND PURPOSE:

Tissue removal can be a simple process of withdrawal of the entire organ, piecemeal removal with surgical clamps, or mechanical morcellation. Different mechanical morcellators exist that each have advantages and disadvantages. We have investigated a particular morcellator having an internal mechanized blade system that increases the chances of damage to tissue isolation sacks but removes large volumes of intact organ that can more readily be evaluated histologically. The primary premise of this investigation is that a fluid-filled sack would be less likely to be damaged by the activated blades of the morcellator.

MATERIALS AND METHODS:

Utilizing a Steiner Morcellator (Karl Storz, Culver City, CA), two porcine kidneys were morcellated within the large LapSac (Cook Urological, Spencer, IN). Two environmental variables were evaluated: dry sac morcellation and fluid-filled sac morcellation. Each session was timed, fluid leakage identified, grasping of the sacks quantified, and gross spillage noted. The tissues were submitted for pathologic evaluation to quantify any differences grossly or histologically. All LapSacs were inspected for gross violation and inflated to distention with fluid to check for tiny leaks.

RESULTS:

The Steiner Morcellator worked much better within the confines of the LapSac filled with fluid. There were no perforations in our experimental setting. It was not possible discern use of fluid-filled sacks histologically.

CONCLUSIONS:

The Steiner Morcellator can be utilized safely in the LapSac if cautious observation and fluid-filled sack conditions are maintained. The extracted tissue is easily evaluated histologically.
