【Abstract】 Objective To investigate the surgical management of dural injuries and postoperative cerebrospinal fluid(CSF) fistulas in spinal surgeries and to observe cl inical outcomes, since intraoperative injury of dura mater and postoperative CSF fistulas are common compl ications of spinal surgeries. Methods A retrospective research was designed and 405 patients with complete data who underwent spinal surgeries between June 2002 and March 2006 were acquired, including 298 cases of male and 107 cases of female, with the mean age of 46.2 years (ranging from 11 years to 78 years). The course of disease lasted from 3 months to 5 years. A total of 28 cases of intraoperative dural injuries and durotomies (28/405, 6.91%) were recorded, including 3 cases of cervical spinal surgery (3/152, 1.97%), 19 cases of thoracic and lumbar spinal surgery (19/239, 7.95%) and 6 cases of sacral surgery (6/14, 42.86%). CSF fistulas occurred in 6 cases of 28 patients. There were 2 cases in which no intraoperative dural injury was detected but CSF fistulas occurred after operation. The incidence of postoperative CSF fistula was 1.98% (8/405). Surgical management included closure of breach in the dura mater, oversewing every layer of the wound, bed rest and compression dressing and so on. Cl inical outcomes of surgical management were recorded. Results The average followup lasted for 1 year and 5 months (ranging from 3 months to 4 years). Preoperative symptoms remitted to different extents There were 8 cases of postoperative CSF fistula which were cured ultimately. A total of 6 cases of CSF fistulas from dorsal injuries of dura mater were treated mainly by bed rest, compression dressing and reoperations, while 2 cases of fistulas from ventral and lateral injuries of dura mater were treated by additional continuous cerebrospinal fluid drainage using a lumbar subarachnoid catheter. One case of central nervous system infection occurred and was treated successfully by multi-discipl inary disposal. Conclusion Timely and correct surgical intervention and postoperative management can help to heal dural injuries in spinal surgeries and can prevent occurrence of postoperative CSF fistulas.

Objective To analyze the medium and long-term effectiveness of microendoscope-assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for lumbar degenerative diseases in comparison with conventional tubular retractor-assisted MIS-TLIF. Methods Between November 2008 and March 2013, 53 patients with single segment lumbar degenerative diseases were enrolled. According to the different working channel performed, 28 patients were treated by microendoscope-assisted MIS-TLIF (observation group), while the remaining cases received conventional tubular retractor-assisted MIS-TLIF via Wiltse approach (control group). Preoperative baseline data, including age, gender, body mass index, disease etiology, operated level, the ration for requiring bilateral canal decompression, and preoperative visual analogue scale (VAS) socre of low back pain and leg pain, Japanese Orthopedic Association (JOA) score, Oswestry disability index (ODI) score, showed no significant difference between the two groups (P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy time, postoperative analgesic drug dose, postoperation in-bed time, and perioperative complication incidence were recorded respectively and compared between the two groups. Radiographic evaluation of interbody fusion was performed based on Bridwell grading system at 2 years after operation. VAS scores of low back pain and leg pain, JOA score, and ODI score were assessed before operation, at 2 years after operation, and at last follow-up respectively. Surgical outcome satisfaction was assessed by modified MacNab criteria at last follow-up. Results When compared with those in control group, both intraoperative blood loss and postoperative analgesic drug dose were significantly decreased in observation group (P<0.05); similarly, the operation time and intraoperative fluoroscopy time were also significantly increased in observation group (P<0.05). There was no significant difference of postoperative in-bed time between the two groups (t=–0.812, P=0.420). Both groups were followed up 6-10.3 years, with an average of 7.9 years. Regarding perioperative complication, its incidence was 14.3% and 20.0% in observation group and control group, respectively, showing no significant difference between both groups (χ2=0.306, P=0.580). Specifically, there were intraspinal hematoma formation in 1 case, incision infection in 1 case, urinary infection in 1 case, transient delirium in 1 case in observation group. By contrast, there were dural tear and cerebrospinal fluid leakage in 1 case, urinary infection in 1 case, pneumonia in 1 case, transient delirium in 2 cases in control group. Bridwell criterion was used to judge the intervertebral fusion at 2 years after operation, the fusion rates of observation group and control group were 92.9% and 92.0%, respectively, showing no significant difference (χ2=0.162, P=0.687). At both 2-year postoperatively and last follow-up, the VAS scores of low back pain and leg pain, JOA score, and ODI score were significantly improved when compared with those before operation (P<0.01), whereas no significant difference between the two groups at either time point was found (P>0.05). At last follow-up, the results of patients’ satisfaction with surgery evaluated by modified MacNab criteria, and the excellent and good rates of the observation group and the control group were 96.4% and 92.0%, respectively, showing no significant difference (χ2=0.485, P=0.486). Conclusion The medium and long-term effectiveness of microendoscope-assisted MIS-TLIF are similar to those of conventional tubular retractor-assisted MIS-TLIF for lumbar degenerative diseases. The former operation has the additional advantages in terms of more clear surgical site visually, less intraoperative blood loss, and reduced postoperative analgesic dose, all of which seem more feasible to clinical teaching.
Objective To evaluate the current status of classification and repair methods for dural injury caused by spinal surgery or trauma, providing new strategies and ideas for the clinical repair of dural injury and the development of related materials. MethodsThe literature related to dural injury both at home and abroad in recent years was thoroughly reviewed and analyzed in order to draw meaningful conclusions. ResultsThere have been numerous retrospective studies on dural injury, but there is a scarcity of prospective and multi-center studies, resulting in a low level of evidence-based research. The incidence and risk factors of dural injury have primarily been studied in relation to common degenerative spinal diseases of the cervical and lumbar spine, with insufficient research on thoracic spine-related diseases. Currently, a universally recognized method for grading and classifying dural injury has not been established, which hampers the development of clinical guidelines for their repair. Furthermore, although there are repair materials and surgical strategies available to address clinical issues such as suture leakage and surgical repair of dural injury in complex locations, there is a lack of comprehensive clinical research and evidence-based data to validate their scientificity and reliability. ConclusionRegardless of the classification of dural injury, suture remains the most important repair method. It is important to further develop new patches or sealants that can meet clinical needs and reduce the difficulty of repair.
Objective To analyze the early effectiveness of unilateral biportal endoscopic discectomy (UBED) combined with annulus fibrosus suture in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 19 patients with LDH treated with UBED and annulus fibrosus suture between October 2020 and October 2021 were retrospectively analyzed. There were 12 males and 7 females with an average age of 39.1 years (range, 26-59 years). The operative segment was L4, 5 in 13 cases, and L5, S1 in 6 cases. The mean disease duration was 6.7 months (range, 3-15 months). Preoperative neurological examination showed that muscle strength, sensation, and tendon reflex weakened or disappeared in varying degrees. Single annulus fibrosus suture (14 cases) or anchor assisted annulus fibrosus suture (5 cases) was selected according to the location of annulus fibrosus tears. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months, and 6 months after operation. Oswestry disability index (ODI) was used to evaluate the function recovery of lumbar spine before operation and at 3 days, 3 months, and 6 months after operation. At 3 days and 3 months after operation, MRI was used to examine the removal of nucleus pulposus and decompression of nerve root. MacNab criteria was used to evaluate the effectiveness at 6 months after operation and the recovery of nerve root function was recorded. Results All operations were successfully completed with a mean operation time of 52.7 minutes (range, 40-75 minutes). There was no complication such as nerve injury, spinal cord hypertension syndrome, or dural sac tear during operation, and no complication such as infection, aggravation of nerve damage, or cerebrospinal fluid leakage after operation. All the patients were followed up 6-10 months (mean, 8.2 months). Postoperative MRI showed that the herniated disc was completely removed and nerve roots were fully decompressed. During the follow-up, there was no recurrence of disc herniation. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and those at 6 months after operation further improved than those at 3 days and 3 months after operation, all showing significant differences (P<0.05). At 6 months after operation, MacNab standard was used to evaluate the effectiveness, and the results were excellent in 14 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 94.7%. Neurological examination showed that the sensation and muscle strength of the affected nerve root innervated area recovered significantly when compared with those before operation (P<0.05); the recovery of tendon reflex was not obvious, showing no significant difference when compared with that before operation (P>0.05). ConclusionUBED combined with annulus fibrosus suture is a safe and effective technique for LDH and early effectiveness is satisfactory.
