A study testing VI-RASD use in minimally invasive right or left colectomy and Right or Left colectomy in people with Colon Cancer and Colon Polyp, run by Virtual Incision Corporation at 3 sites in United States.
Trial summary
For patients with colon polyps (clumps of cells in the lining of the colon) treatment often requires removal of the affected portion of the colon.

About this study
Official title: Virtual Incision Robotically Assisted Surgical Device (VI RASD) for Umbrella Surgical Procedures: Minimally Invasive Right and Left Colectomy
For patients with colon polyps (clumps of cells in the lining of the colon) treatment often requires removal of the affected portion of the colon. Both conventional laparoscopic and robotically assisted minimally invasive surgery have been shown to have reduced complication rates and shorter hospital stays.
This study aims to look at the use of the VI RASD as a robotic surgical device in right or left colectomy procedures to see if the device performs as intended and is safe for use.
Read the detailed description
The purpose of the clinical study is to evaluate the device's indications for use in the clinical environment. The VI RASD is a surgical tool intended to assist in the endoscopic manipulation of tissue during bowel resections. The VI RASD is designed to allow a surgeon to perform minimally invasive colon procedures in the same fashion used in laproscopic and robotically assisted surgery with a single incision site in the abdominal wall.
The study will evaluate the efficacy of the VI RASD in manipulating and dissecting the right or left colon and preparing the colon for resection. The safety profile of the device will also be assessed through analysis of overall intraoperative and post operative adverse events as compared to published literature.

What is being measured
The primary outcome is the main question the study is designed to answer.
Efficacy: Number of Participants With Successful Completion of the VI RASD Steps in Colectomy Procedures Without Conversion to Open Surgery
Count and calculated percentage of enrolled subjects in which the VI RASD steps were successfully completed and did not require conversion to open surgery.
VI RASD steps include: the VI-RASD system is inserted and deployed to corresponding abdominal cavity, used to manipulate and dissect the colon allowing for transection of the colon and small bowel, and system is removed from the abdominal cavity.
