简要总结

Lumbar disc herniation (HDL) is one of the main causes for low back pain and sciatica. Although non surgical care remains the gold standard as first treatment, lumbar discectomy is used to effectively relieve symptoms that persist for prolonged periods.

With surgical techniques evolution, minimally invasive spine surgery has emerged in recent decades as an alternative to conventional open surgery and is widely used for HDL treatment. Several minimally invasive surgical endoscopic techniques have been developed for disc herniation: Single Portal Endoscopy (SE), Video Assisted Endoscopic Discectomy, and recently Unilateral Biportal Endoscopy (UBE).

Currently, SE is considered as the minimally invasive surgery gold standard for HDL but, over the past two years, UBE for the treatment of degenerative lumbar diseases has increased exponentially with faster learning curve than other endoscopic techniques.

As an emerging technique, further studies are needed to better understand UBE. This is why Dr. Cristini's team wish to analyze a cohort of patients for whom this technique has been used since July 2022, in particular the complication rate.

Controlling a new technique requires a learning phase. This is why Dr. Cristini's team also wishes to describe the learning curve on the cohort of patients for whom UBE was used since July 2022.

详细描述

Lumbar disc herniation (HDL) is one of the main causes for low back pain and sciatica, affecting 1 to 5% of the population each year. Although non surgical care remains the gold standard as first treatment, lumbar discectomy is used to effectively relieve symptoms that persist for prolonged periods.

With surgical techniques evolution, minimally invasive spine surgery has emerged in recent decades as an alternative to conventional open surgery and is widely used for HDL treatment. Compared to traditional open surgery, minimally invasive surgical technique offers muscle and bone sparing, pain reduction and faster recovery, allowing patient management in Enhanced Recovery After Surgery (RAAC).

Several minimally invasive surgical endoscopic techniques have been developed for disc herniation: Single Portal Endoscopy (SE), Video Assisted Endoscopic Discectomy, and recently Unilateral Biportal Endoscopy (UBE). SE relies on a single entry route whereas UBE is based on two entry routes : one way for optical instruments and saline irrigation system and one way for surgical instruments. Currently, SE is considered as the minimally invasive surgery gold standard for HDL treatment thanks to its advantages for controlling muscles trauma, reducing hospital stay and maintaining spinal segment stability.

Over the past two years, UBE for the treatment of degenerative lumbar diseases has increased exponentially with faster learning curve than other endoscopic techniques.

UBE allows a wider field of vision, wide and ergonomic operating gestures, is minimally invasive and contributes to complete nervous decompression and faster recovery. With UBE, the surgeon can use one hand to guide endoscope and he other one to guide surgical instruments . In addition, UBE generates less trauma, less bleeding, rapid recovery and good effectiveness in HDL treatment . UBE can significantly reduce postoperative nerve fibrosis, and postoperative spinal instability incidence.
