Li Y, Wang B, Li H, et al. - A retrospective study was conducted to construct and verify a model for evaluating patients’ recurrence risk factors before surgery so that surgeons can choose other surgical techniques when necessary. Researchers included a total of 1,807 patients who had undergone percutaneous endoscopic lumbar discectomy (PELD) at the hospital between 2012 and 2015. They retrospectively analyzed data for 1,807 patients who had undergone PELD at our hospital at some point between 2012 and 2015; all patients had been monitored for at least 5 years after surgery. Individuals were classified into a recurrence group and a nonrecurrence group. A large cohort of individuals had undergone long-term monitoring, and 11 risk factors were verified for evaluating each patient's risks before surgery to prognosticate the postoperative recurrence of LDH following PELD. It was shown that the risk of recurrence may be effectively decreased with the use of alternative surgical techniques in high-risk cases.
