Clinical Studies

Haptic Feedback A Force For Increased Resident Autonomy In Colorectal Robotic Surgery Rochester, Minn.
The purpose of this study to assess and compare the haptic functionality by comparing attending interventions required to ensure optimal outcomes and potential improvements in timing and efficiency of procedure skill completion over time for surgical trainees within the DV5 robotic system in real-world surgical environments.
KM3D Multicenter Cancer Consortium Study: Validation of In Vitro 3D Cell Culture Models for Tumor Drug Sensitivity After Tissue Removal Rochester, Minn.
This study will assess the ability of the Pathos platform to predict which patients will respond to certain colorectal cancer drug treatments. To demonstrate that for patients with advanced colorectal cancer, prediction scores based on in vitro tumor organoid drug response are positively associated with the rate of first line response.

To demonstrate that for patients with advanced colorectal cancer, prediction scores based on in vitro tumor organoid drug response are positively associated with progression free survival.

To demonstrate that for patients with advanced colorectal cancer who meet the endpoint of first line response, prediction scores based on in vitro tumor organoid drug response are positively associated with duration of first line response.

A Randomized, Double-Blind, Placebo-Controlled Proof of Concept Study to Evaluate LB1148 for Return of Gastrointestinal Function, Post-Operative Ileus and Intra-Abdominal Adhesions in Subjects Undergoing Elective Bowel Resection (PROFILE) (PROFILE) Rochester, Minn.
The purpose of this study is to establish preliminary evidence of the effiectiveness, safety, and tolerability of LB1148 for the treatment of post-operative ileus and intra-abdominal adhesions in subjects undergoing elective bowel resection.

A Pilot, Prospective, Randomized, Controlled, Multicenter Technical Feasibility Clinical Study Comparing Standard Anastomosis Closure Technique To Standard Closure Techniques Plus Sylys® Surgical Sealant Jacksonville, Fla., Rochester, Minn.
The Cohera Sylys® Surgical Sealant study is a prospective, randomized, controlled, multicenter technical feasibility clinical study comparing standard anastomosis closure technique (Control) to standard closure techniques plus Sylys® Surgical Sealant (Test) during colorectal and ileorectal anastomosis procedures.
A Prospective, Multi-Center Investigation of the da Vinci SP® Surgical System in Colorectal Procedures for Benign and Malignant Disease Rochester, Minn., Jacksonville, Fla.
The purpose of this study is to confirm the safety and performance of the da Vinci SP Surgical System, Instruments and Accessories in a complex colorectal procedure such as low anterior resections.
Hydration in The Surgical Patient: A Novel Investigational Approach Rochester, Minn.
The goal of the study is to assess the correlation of Leo Technology hydration algorithm to various physiological parameters in the perioperative period for those undergoing colorectal surgery.
