Stopped: The study was terminated. Six subjects were consented \& all were withdrawn before any study activities took place.
The primary goal of the study is to evaluate the safety of the EndoLift Liver Retractor as an internal laparoscopic liver retraction device. The secondary goals of the study are to evaluate the efficacy of the EndoLift Liver Retractor as an internal laparoscopic liver retraction device and to identify 'best practices' for device utilization. This study evaluates the use of a specific type of liver retractor (EndoLift). Liver retractors are often necessary during MIS procedures, but this retractor is the only device which is deployed internally (NOT requiring additional skin punctures/incisions for placement of the liver retractor device). All patients undergoing minimally invasive surgery (MIS) at Duke Regional Hospital will be approached. The new device is expected to have a minimal risk safety profile. The investigators believe that these risks are no more than would be encountered by using any other commercially available retraction device available on the market today. Data will be collected and analyzed by the identified investigators. Continuous variables will be analyzed via T-test and Chi-square analysis will be applied to discontinuous variables. Statistical analysis software such as SPSS® will be utilized when necessary.
