Endoscopic Lumbar Discectomy

Purpose. Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive disc surgery that can be performed under local anesthesia and requires only an eight-mm skin incision. For the patients with lumbar foraminal stenosis, the migrated disc is difficult to remove with a simple transforaminal approach. In such cases, the foraminoplasty techniques can be used. However, obtaining efficient foramen enlargement while minimizing radiation exposure and protecting the nerves can be challenging. Methods. In this study, we propose a new technique called the Kiss-Hug maneuver. Under endoscopic viewing, we used the bevel tip of a working cannula as a bone reamer to enlarge the foramen. This allowed us to efficiently enlarge the lumbar foramen endoscopically without the redundancy and complications associated with reamers or trephines. Results. Details of the four steps of the Kiss-Hug maneuver are reported along with adverse events. The advantages of this new technique include minimizing radiation exposure to both the surgeon and the patient and decreasing the overall operation time. Conclusion. The endoscopic Kiss-Hug maneuver is a useful and reliable foraminoplasty technique that can enhance the efficiency of foraminoplasty while ensuring patient safety and reducing radiation exposure.

Abstract Background: Lateral recess stenosis (LRS) is a common degenerative disease in the elderly. Since the rise of comorbidity is associated with the increasing age, the percutaneous endoscopic lumbar decompression is advocated. The objective of this study was to compare the clinical outcomes of percutaneous endoscopic lumbar decompression in LRS via TESSYS or TESSYS-ISEE approach. Methods: A total of 45 and 42 consecutive patients with limp or radiculopathy symptoms underwent percutaneous endoscopic lumbar decompression using transforaminal endoscopic spine system (TESSYS) and TESSYS-ISEE, respectively. The radiation exposure and operation time, time to return to work, and complications were compared between two groups. Their clinical outcomes were evaluated with visual analogue scale (VAS) leg pain score, VAS back pain score, Oswestry Disability Index (ODI) and Modified MacNab’s criteria. Results: The average values of radiation exposure and operative time in TESSYS group were significantly higher than those in TESSYS-ISEE group (P<0.05). The postoperative VAS and ODI scores in both groups were significantly improved compared with before the operation (P<0.05). In addition, the VAS score of the leg and ODI score in the TESSYS-ISEE group were significantly lower than those in TESSYS group at 1 week follow-up (P<0.05). The good-to-excellent rates of the TESSYS and TESSYS-ISEE group were 88.89 and 90.48%, respectively, whereas the complication occurrence rates were 6.67 and 4.76% in TESSYS and TESSYS-ISEE groups, respectively. Conclusions: TESSYS-ISEE can be applied to treat LRS safely and effectively with short radiation exposure and operation time. This approach was comparable to the TESSYS approach with improved VAS leg pain and ODI score in short period after operation. However, potential complications and risks still needs to be considered.

Study Design: Retrospective study. Objective: To compare the clinical efficacy of posterior lumbar laminectomy decompression under full endoscopic technique (Endo-LOVE) and percutaneous endoscopic medial foraminal decompression (PE-MFD) in the treatment of degenerative lumbar spinal stenosis (DLSS). Methods: Between April 2017 and April 2018, 96 patients with DLSS underwent Endo-LOVE or PE-MFD, including 58 with Endo-LOVE and 38 with PE-MFD. After propensity score matching (PSM), patient characteristics, operation time, intraoperative fluoroscopy times, postoperative bedridden time, hospital stay and postoperative complications were recorded and compared. The clinical efficacy was evaluated according to Oswestry disability index (ODI), visual analogue scale (VAS), lumbar disease JOA and modified MacNab criteria. Results: A total of 96 patients with DLSS were included in the study. After PSM, the 2 groups were comparable in patient demographic and baseline characteristics. The operation time and intraoperative fluoroscopy times in PE-MFD group were significantly more than those in Endo-LOVE group ( P < .05). The operation time in PE-MFD group was significantly less than that in Endo-LOVE group ( P < .05). The intraoperative fluoroscopy times in PE-MFD group were significantly more than that in Endo-LOVE group ( P < .05). The ODI, VAS and lumbar disease JOA in the 2 groups were significantly improved comparing with those before operation ( P < .05). According to the modified MacNab criteria, the excellent and good rates of the 2 groups were 93.5% in Endo-LOVE group and 87.1% in PE-MFD group ( P > .05). Conclusion: Endo-LOVE and PE-MFD technique can both effectively treat DLSS, and the short-term follow-up results are positive. Endo-LOVE technique has the advantages of fast puncture positioning, less radiation exposure and wider indications. However, PE-MFD needs more radiation exposure and has the possibility of incomplete decompression for complex multiplanar spinal stenosis.

Abstract OBJECTIVE: We report three patients with symptomatic isolated fourth ventricle after ventriculoperitoneal shunt placement for hydrocephalus associated with ventricular hemorrhage. All three patients were treated successfully with our new method of endoscopic aqueductal stenting under navigating system guidance. METHODS: A therapeutic rigid endoscope was inserted through the thin cerebellar hemisphere, and endoscopic aqueductal stenting was performed via the enlarged fourth ventricle under navigating system guidance. RESULTS: All three patients underwent successful procedures with good outcomes. CONCLUSION: Our method of aqueductal stenting is a reasonable choice for initial treatment of patients with isolated fourth ventricle, and it entails less invasive neurosurgery.
