About this study
Official title: Open Label, Single Center, Randomized Study Evaluating the Feasibility of the Ultravision™ Visual Field Clearing System in Low Pressure Laparoscopic Cholecystectomy Compared To AirsealL® IFS
This post-market clinical study is designed to evaluate the effectiveness of the Ultravision™ System when compared to the Airseal® iFS within an approved indication for use, namely laparoscopic cholosystectomy.
Read the detailed description
The primary hypothesis being tested in this study is that Ultravision facilitates the utilization of lower pneumoperitoneal pressures whilst maintaining an adequate visual field throughout the procedure with low demand for CO2 replenishment to maintain pneumoperitoneal pressure. Comparisons in terms of surgical field visualization, procedure times, and CO2 consumption will be conducted in order to determine whether or not any clinical benefits are derived from the use of the Ultravision™ System compared to the Airseal® iFS. Low pressure laparoscopy for this study is set at 10mmHg. This is a prospective, open-label, randomized controlled study. The study will include two study arms. Patients undergoing laparoscopic cholecystectomy will be randomized to either "Ultravision" (study arm 1) or Airseal® iFS (study arm 2). Both groups will conduct the procedure at 10mmHg, considered to be low pressure/low impact laparoscopic surgery. The study will enroll 30 patients, 15 per group. Both devices are being used according to their cleared label claims.
