[Effect and complication among different kinds of spinal endoscopic surgery for lumbar disc herniation].

PETD,PEID and UBE techniques could achieve good early clinical effects in treating lumbar disc herniation with similar complication rates. Both of PETD and PEID are single-channel minimally invasive surgery,with mild intraoperative tissue damage and quick postoperative recovery; while intraoperative fluoroscopy of PETD was relatively more frequent, and PEID was more suitable for L₅S₁ segment;UBE is a two-channel surgery,in which the intraoperative soft tissue damage is more severe,but exposure is broad,which is more suitable for complex cases.
