General Surgery Research

The Division of Gastrointestinal and General Surgery participates in ongoing research to help find ways to improve health and treat diseases. Clinical research works to help determine the safety and effectiveness of new medications, new devices, or treatment approaches intended for human use. Clinical trials rely on the participation of human volunteers to help answer questions about treatments for diseases and conditions. The Division of General Surgery participates in many different types of research from industry sponsored trials, clinical registries as well as physician initiated research projects.

There are many benefits from participating in clinical research including the ability for participants to play a more active role in their own healthcare, gain access to new research medications or treatments before they are commercially available, as well as to help others by contributing to new innovative research.

Currently the Division of General Surgery participates in research focused on the areas of colorectal surgery, pancreatic surgery, esophageal surgery, hernia surgery, nutrition, and registry databases pertaining to colorectal, esophageal and pancreatic cancers.

For more information pertaining to current research projects or if you are interested in participating in research with the division of general surgery, please contact us to learn more at 503 494-4949.
