Kim CH, Chung CK, Choi Y, et al. - Through a retrospective cohort study of a nationwide sample database of adult patients (N = 1,856) who underwent first surgery for lumbar herniated intervertebral disc disease (HIVD) during 2005 to 2007, experts contrasted the long-term incidence of reoperation for lumbar HIVD following major surgical techniques (open discectomy [OD]; laminectomy; percutaneous endoscopic lumbar discectomy [PELD]; fusion). The overall cumulative incidences of reoperation were 4%, 6%, 8%, 11%, and 16% at 1 year, 2 years, 3 years, 5 years, and at 10 years, respectively. Following OD, laminectomy, PELD, and fusion, the cumulative incidences of reoperation were 16%, 14%, 16%, and 10%, respectively, at 10 years postoperation, with no variation between the surgical techniques. Nevertheless, the distribution of reoperation types was significantly distinctive according to the first surgical technique. In 80% of patients following OD and in 81% of patients following PELD, OD was chosen as the reoperation surgical technique. Hence, during the 10-year follow-up period, among OD, laminectomy, PELD, and fusion, the probability of reoperation did not vary. Nevertheless, OD was the most usually practiced technique in reoperation.
