Simulation Study Comparing the Effectiveness of the Gynecare Morcellex, the MOREsolution, and the Rotocut G1 Tissue Morcellators

Abstract

Laparoscopic surgery has revolutionized the manner in which many operations are performed today. The volume of tissue to be removed during some operations can be a limiting factor for laparoscopy and is frequently a reason for converting from a minimally invasive laparoscopic surgical approach to the conventional open surgical approach. The introduction of the electronic morcellator has helped facilitate the removal of large specimens via minimally invasive surgery. The purpose of this study is to evaluate the effectiveness of the Gynecare Morcellex® morcellator (Ethicon, Inc., Somerville, NJ), the MOREsolution™ morcellator (Blue Endo, Lenexa, Kansas), and the Rotocut™ G1 morcellator (Karl Storz, Tuttlingen, Germany) tissue morcellators based upon their ease of use and efficacy in a simulation setting among an unbiased cohort of novice surgeons. University of Central Florida College of Medicine students were observed using the three different morcellators in a randomized order on 250 g beef tissue models and were surveyed on the ease of use of the morcellators. The MOREsolution™ tissue morcellator demonstrated significantly faster tissue morcellation times (544.6 ± 123.0 sec) and produced a higher number of long tissue fragments (7.44 ± 0.683) compared to the Rotocut™ G1 morcellators' time (609.7 ± 153.2 sec) and number of long tissue fragments (6.00 ± 0.638). No significant differences were found between the Gynecare Morcellex® and other morcellators in the total number of fragments obtained nor study participant opinion on the ease of use of the three morcellators. This study demonstrates that the MOREsolution™ morcellator is a faster morcellator and produces larger tissue fragments as compared to the Rotocut™ G1; however, more studies should be performed to confirm these findings in a clinical setting.
