(HealthDay News) — One in six older patients having hernia surgery undergo reoperation for recurrence within 10 years, according to a research letter published in the March 1 issue of the Journal of the American Medical Association.

Ryan Howard, M.D., from the University of Michigan in Ann Arbor, and colleagues used fee-for-service Medicare claims data to estimate the long-term incidence of operative hernia recurrence among older adults undergoing elective, inpatient, ventral or incisional (162,292 patients) and umbilical (13,443 patients) hernia repair from 2007 through 2018 (median follow-up, 5.3 years).

The researchers found that 14.3% of patients underwent reoperation for hernia recurrence, with an adjusted cumulative incidence of reoperation for recurrence of 16.1% at 10 years after surgery. For ventral or incisional hernia repair, the 10-year adjusted cumulative incidence of reoperation for recurrence was 16% following open repair and 18.8% following minimally invasive repair. For umbilical hernia repair, the 10-year adjusted cumulative incidence of reoperation for recurrence was 12.3% after open repair and 14.5% following minimally invasive repair. The authors believe the study likely underestimated the incidence of clinical hernia recurrence because not all patients with recurrence undergo reoperation.

“Compared with historical 10-year reoperation rates of approximately one in five patients, these results suggest that outcomes have only marginally improved,” the authors write.
