Clinical Data Validates Benefits of the GI Supply RenovaRP® Paracentesis Management System for Patients with Ascites

Clinical Data Validates Benefits of the GI Supply RenovaRP® Paracentesis Management System for Patients with Ascites

March 3, 2022 | Mechanicsburg, PA

In a peer-reviewed research paper entitled “Paracentesis: faster and easier using the RenovaRP® pump,” published online in February 2022 by Diagnostic and Interventional Radiology, researchers observed a substantially higher fluid flow rate during paracentesis using the RenovaRP® system compared to wall suction.(1) The purpose of this study was to investigate if the use of RenovaRP® as a treatment for ascites would reduce procedure time compared to standard wall suction without increasing adverse effects, such as hypotension or abdominal pain.(2)

Procedure room time decreased from 53 minutes with wall suction to 31 minutes with RenovaRP® (p < 0.001).(3) The paper’s authors noted that the RenovaRP® pump is portable, simple to use, requires little staff training, and can be used to perform paracentesis outside of interventional radiology. The authors also highlighted that, as a self-contained system, it avoids exposing medical team members to patients’ body fluids, which may occur during exchange of wall-suction canisters.(4)

“Exposure to a patient’s body fluids is a risk faced by healthcare professionals that must change cannisters or open cannisters to pour in the material that solidifies the removed fluid,” said Karen T. Brown, MD, a co-author of the research paper. She serves as the chief of Interventional Radiology in the Department of Radiology and Imaging Sciences, professor of Radiology at the University of Utah and works at both the Huntsman Cancer Center and University Hospital.

Although the study was not designed to investigate patient or staff preferences, RenovaRP® conferred several advantages. Placing the system on a cart to enable paracentesis in patients’ hospital rooms saves time for patients and staff.

According to Dr. Brown, “The patient experience was comparable to conventional wall suction. Patients said they liked Renova better, which might have been due in part to it being a faster procedure.”

In their discussion about costs associated with wall suction and the RenovaRP® system, study authors noted:

  • In certain high-volume centers where paracentesis procedures are performed frequently, the RenovaRP® pump can be expected to provide superior through-put with relatively minimal added procedural costs.
  • The RenovaRP® pump offers providers and patients substantially faster procedure times without adverse outcomes.(5)

“While we anticipated positive outcomes from this clinical study, our team was gratified that the results clearly support the benefits of the RenovaRP® system,” said Rhett Klein, Vice President of Sales and Marketing, GI Supply. “We are dedicated to enhancing patient safety and satisfaction in a cost-effective system that also supports the needs of medical staff.”

The system consists of three parts: the peristaltic pump, the paracentesis kit containing standard items and the proprietary RenovaRP® Tubing, and the RenovaRP® Drainage Bags, which offer a larger capacity than the standard one-liter bottles and cannisters.

INTENDED USE: The GI Supply RenovaRP® Paracentesis Pump is intended as a peristaltic pump to remove ascitic fluid from the abdominal cavity in conjunction with the GI Supply RenovaRP® Paracentesis Kit and is intended to be used by medically trained healthcare professionals knowledgeable about paracentesis.

As a physician-founded company, we strive for deep clinical input into all that we do. GI Supply is broadening our portfolio with solutions that allow physicians to perform more-advanced procedures safely, efficiently, and economically. For more information, visit
