Objective: To analyze the complications of lumbar intervertebral disc herniation treated with percutaneous endoscopic lumbar discectomy(PELD), and discuss how to avoid these complications.

Methods: The data of 132 patients with lumbar intervertebral disc herniation underwent PELD from October 2013 and June 2015 were retrospectively analyzed, including 85 males and 47 females with an average age of 42.9 years old. There were 6 cases of L₃,₄, 68 of L₄,₅ and 58 of L₅S₁. The incidences of intraoperative and postoperative complications were analyzed.

Results: There was spinal dura mater injury in 1 patient, but no cerebrospinal fluid leakage and nerve function deficit was found, the muscle strength did not decrease postoperatively and the incision healed well. Two patients converted to open surgery ultimately because of stenosis of the intervertebral foramen and adhesion between nucleus pulposus and spinal dura mater; two patients complicated with early recurrence(in 3 months);nucleus pulposus residue developed in 3 patients; all of them were treated by open surgery and got satisfactory results. One patient with heart disease history complicated with supraventricular tachycardia after surgery and 2 patients with the increased cerebrospinal fluid pressure during surgery.

Conclusions: PELD have a steep learning curve, and the technology is a safe and effective method in treating lumbar disc herniation, but the beginners must have enough open surgery experience, and to grasp indications strictly.

Background: To investigate and quantify the influence of body mass index (BMI) on the efficacy and outcomes of percutaneous transforaminal endoscopic surgery (PTES), a novel minimally invasive surgical technique in the treatment of lumbar disc herniation (LDH).

Methods: A total of 55 patients suffering from single-level LDH with or without high iliac crest, scoliosis or calcification, who underwent PTES in our department from January 2019 to December 2021 were retrospectively analyzed. Patients were divided into two groups according to BMI.
