PUYALLUP, Wash. — Puyallup hernia surgeon Robert C. Wright continues to offer solutions for more
hernia patients. And research on the effects of entrapment neuropathy is the healing pathway.
Wright, who heads Cascade Hernia Institute at Meridian Surgery Center, conducted the independent
research with Don Born, a neuropathologist with Stanford University School of Medicine. The first phase
of the research proved early repair of hernia damage is an effective intervention to avert nerve
damage—and reduce the likelihood of long-term pain.
The University of Washington Department of Statistics provided analysis of the research statistics. The
peer-reviewed journal Hernia published the research in October 2017, and the American Journal of
Surgery published the research in its May 2017 edition.
“Like nerve enlargement and increased pain in carpal tunnel, we found early hernia surgery could avoid
pain from entrapment neuropathy in primary inguinal hernias,” said Wright.
In 63 percent of hernia patients studied, inguinal nerve enlargement was similar to entrapment
neuropathy in carpal tunnel syndrome. The hernia in the groin entraps a nerve and injures it, which
causes swelling much like the nerve injury seen with carpal tunnel syndrome.
The Neuropathology Department at Stanford University School of Medicine has provided funding for a
second phase of the research that will explore evidence of nerve injury in patients with inguinal hernia
and correlating that with their pain scores before the hernia is repaired.
As with past independent research, Wright involved local undergraduates in the research: Jordan Landis,
a sophomore at Pacific Lutheran University, majoring in chemistry, and Troy Salisbury, a sophomore at
Boise State University majoring in biology. The students received approval from the Tacoma General
Hospital Institutional Review Board to participate in phase II of this research.
Wright presented the research locally at the Northwest Pacific Surgical Association last November and at
the American Hernia Society Meeting in Cancun, Mexico in March. He also highlighted the research
findings for a presentation to the European Hernia Society in Vienna last May.
