ObjectiveTo discuss the significance and the short-term effect of bone puncture technique in transiliac approach to intervertebral endoscopic discectomy for the treatment of L5/S1 intervertebral disc herniation.MethodsNineteen patients were diagnosed as L5/S1 disc herniation and treated using transiliac approach to endoscopic discectomy (group I), and 20 patients were diagnosed as non-L5/S1 disc herniation and underwent conventional approach (group R). Leg pain was evaluated by VAS. MacNab ratings of the last follow-up were recorded to evaluate early clinical efficacy, and postoperative complications were recorded to evaluate surgical safety. The imaging changes of the patients 3 months after surgery were observed.ResultsOne patient in group I, who felt abnormal in nerve roots, underwent symptomatic treatments, such as rehydration and hormone, and the abnormalities disappeared 3 days after treatment. There were no significant significances in operative time and intraoperative fluoroscopy times between groups I and R (p > 0.05), but there was a higher tendency in group I. The VAS scores of post-operation were significantly lower than that of pre-operation in the two groups (p < 0.05), but there were no significant differences between the two groups (p > 0.05). The MacNab score of the last follow-up showed excellent rate (95%) and good rate (90%) in groups I and R, respectively.ConclusionsBone puncture-combined transiliac approach to intervertebral endoscopic surgery could locate iliac puncture point individually, and establish a good iliac channel, which is safe, effective, and minimally invasive.
BackgroundThis study aimed to evaluate the efficacy of transforaminal endoscopic discectomy (TED) in the treatment of obese patients with lumbar disc herniation (LDH).Material/MethodsA total of 69 obese patients with LDH (35 males and 34 females; age range, 24 to 43 years; median age, 34 years) were included in this study. These patients had undergone TED from March 2011 to December 2015 in the Third Hospital of Hebei Medical University. Their clinical and follow-up data were prospectively analyzed. The degree of pain and disability were measured on the basis of the Visual Analog Scale (VAS) at 1 day before surgery, immediately after surgery, and 3 months after surgery. Neurologic functions were measured on the basis of the Japanese Orthopaedic Association (JOA) system 1 day before surgery and 3 months after surgery. The MacNab score at last follow-up was recorded to evaluate the early clinical efficacy. Complications during and after the operation were recorded to evaluate the safety of surgery.ResultsTwo patients experienced abnormal sensations in the export nerve root zone postoperatively, which disappeared after 3 days of treatment with dehydration and administration of hormone (dexamethasone). Three cases of recurrence were observed at 6 months, 7 months, and 9 months postoperatively; they were scheduled to receive total laminectomy combined with bone grafting internal fixation. A total of 67 patients were followed up for 3–23 months and mean follow-up was 11.8 months. The VAS scores at postoperative 3 months and 1 year were significantly reduced compared to that before the operation, with significant differences between them (t=43.072, P<0.05; t=43.139, P<0.05). The JOA scores at last follow-up postoperatively was significantly higher than that before surgery (t=−60.312, P<0.05). At the last follow-up, 17 cases (25.3%) had excellent outcomes, 39 (58.2%) good, 7 (10.4%) fair, and 4 (5.9%) poor. Overall, 83.5% of patients had excellent or good rates.ConclusionsThe early efficacy of TED is relatively good and safe for the selected obese patients with LDH in this study. Larger-sample studies with longer duration and follow-up are required to detect the safety and effectiveness of TED.
The aim of the current study was to analyze the efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of lumbar degenerative disc disease for senior patients. The clinical and follow-up data of senior patients were retrospectively reviewed. Patients were divided into a PTED group and an open surgery group. Parameters were analyzed, including surgery time, intraoperative fluoroscopy time, intraoperative blood loss, postoperative complications, visual analog scale (VAS) and Japan Orthopedic Association (JOA) scores. Compared with the open surgery group, the surgery time and intraoperative blood loss were decreased, while the intraoperative fluoroscopy time was increased, in the PTED group (P<0.001). Significant improvements in VAS and JOA scores were identified within both groups from preoperative to 12 months following surgery (P<0.001). VAS and JOA scores were significantly improved in the PTEN group compared with the open surgery group at 1 week after surgery (P<0.001), but there was no significant difference between groups prior to and at 12 months following surgery. The incidence of venous thrombosis of the lower extremities in the PTED group was decreased compared with the open surgery group (P<0.05). In the open surgery group, patients suffered from multiple postoperative complications, including constipation, urinary system infection, wound infection, gastrointestinal hemorrhagic stress ulcer, pneumonia, pulmonary embolism, mortality following myocardial infarction, mortality following cerebral infarction, and hemiplegia following cerebral hemorrhage. By contrast, patients in the PTED group did not experience any of these complications. In conclusion, PTED resulted in reduced trauma and a lower incidence of severe complications compared with open surgery, which suggests that PTED is a safe and effective minimally invasive surgery for senior patients with lumbar degenerative disc disease.
BackgroundThe aim of this study was to analyze treatment outcomes and morbidity of contralateral neurological symptom in patients after TLIF surgery and to explore its possible causes.Material/MethodsA retrospective study was conducted involving a total of 476 patients who underwent TILF from 2009 to 2012 in our hospital. These cases were divided into a symptomatic group (Group S) and a non-symptomatic group. The differences in contralateral foramen area and disc-height index(DHI) before and after surgery were compared between Group S and a random sample of 40 cases of non-symptomatic group patients (group N). In addition, according to whether the patient underwent second surgery, Group S patients were further divided into a transient neurologic symptoms group (Group T) and an operations exploration group (Group O). The time of symptom appearance, duration, and symptomatic severity (JOA VAS score) were compared between Group T and O.ResultsAmong the 476 patients, 18 had postoperative contralateral neurological symptoms; thus, the morbidity was 3.7815%. The indicators in Group S were lower than in Group N in the differences in contralateral foramen area and disc-height index(DHI) before and after surgery (p<0.05). Five patients (Group O) in Group S had second surgery because of invalid conservative treatment. The surgical exploration rate was 1.0504%. Compared with Group T, the symptoms of Group O patients appeared earlier, persisted longer, and were more serious (p<0.05).ConclusionsContralateral neurological symptom is a potential complication after TLIF, and its causes are diverse. Surgical explorations should be conducted early for those patients with the complication who present with obvious nerve damage.
