Dr. Haggerty is participating in a multicenter study of explanted hernia meshes from human subjects. The purpose of this study is to determine whether hernia mesh materials undergo physical and/or chemical changes in the body.

The explantation of mesh is usually required if the mesh is infected, but is sometimes necessary if it is thought to be causing chronic pain. The mesh may be removed using laparoscopic or open techniques.

Once the mesh is out of the body, it is placed in formalin and transported to the biomaterials lab at the University of Missouri Columbia for extensive testing to evaluate the physical and chemical properties of explanted mesh. This data is then compared to that of pristine (never implanted) mesh. We hope to apply this information towards the development of new types of mesh materials in the future.

Mesh removal surgery is not a common operation and is technically challenging. It may require removal of scar tissue, dissection of the intestine and complex tissue or biologic mesh closure of the remaining defect.

Dr. Haggerty is developing a regional referral center for patients who may need mesh removal. Patients or physicians can call 847-433-1060 to set up an appointment or talk directly with the doctor. He will accept hospital to hospital transfers for inpatients needing urgent surgical care.
