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.

ObjectiveTo investigate the status of urination in post-spineoperative (cervical thoracic and lumber verteb) patients under the enhanced recovery after surgery (ERAS) mode.MethodsPatients who were admitted to the West China Hospital of Sichuan University from October 2018 to February 2019 were enrolled. The urination status of the patients was collected by using questionnaires. All patients were divided into normal urinating group, induced urinating group and catheterization group according to their urination status after returning to the ward.ResultsA total of 106 patients were included, including 78 (73.6%) who urinated smoothly [the first urinating time (72.18±36.33) min], 20 (18.9%) who urinated after induction [the first urinating time (81.50±41.68) min], and 8 (7.5%) who received catheters after induction failure [the first urinating time (162.50±84.52) min]. The different operation, operation time, position of urination, and postoperative pain degree affecting the placement of urethral catheter differed from each other significantly (P<0.05). Among the three groups, the differences were statistically significant in operation time, operation methods, position of urination (except for the induced urination group vs. catheterization group) and postoperative pain degree (except for the induced urination group vs. catheterization group) in pairs (P<0.05). There was no significant difference in other factors among three groups in pairs (P>0.05).ConclusionsMost post-spineoperative patients can autonomously urinate without catheter under the ERAS mode, which bases on operation methods, operation time, and the first urinating posture after the surgery. Early attention should be paid to patients with dysuresia to promote their early rehabilitation.
ObjectiveTo review the research progress of total endoscopic minimally invasive technique in treating cervical nerve root canal stenosis (CNRCS).MethodsThe related literature at home and abroad was extensively reviewed. The research history, current situation, research progress, advantages and disadvantages of minimally invasive treatment of CNRCS under total endoscope were summarized.ResultsIn recent years, with the continuous development of minimally invasive technique of total endoscope in spine surgery, the surgical treatment methods are also constantly innovated.

Objective To investigate the status of self-perceived burden (SPB) in patients undergoing spine surgery and to explore its influencing factors, in ordering to provide a basis for formulating corresponding nursing interventions. Methods A cross-sectional survey was conducted on patients undergoing spine surgery in Department of Orthopedic Surgery, West China Hospital of Sichuan University between May and August 2024. The patient general information questionnaire, the patient SPB Scale, the Barthel Index, the Medical Coping Modes Questionnaire, and the Social Support Rating Scale were used to investigate the SPB status and its influencing factors in patients undergoing spine surgery. Results A total of 230 patients were included. There were 113 cases in the non-SPB group and 117 cases in the SPB group. There were statistically significant differences in age, marital status, occupation, payment method, the number of family, disease diagnosis, Barthel Index score, caregiver identity, and caregiver gender between the two groups of patients (P<0.05). Among 117 patients with SPB, 83 (36.09%) had mild SPB, 27 (11.74%) had moderate SPB, and 7 (3.04%) had severe SPB. The average SPB scores for mild, moderate, and severe patients were (24.06±2.92), (33.07±2.87), and (44.86±4.56) points, respectively. The results of binary logistic stepwise regression analysis showed that the patient’s marital status, disease diagnosis, and caregiver gender were independent influencing factors for SPB in patients undergoing spine surgery (P<0.05). Conclusion The SPB of patients undergoing spine surgery is at a mild to moderate level, which is affected by factors such as marital status, disease diagnosis, and caregiver gender.
【摘要】 目的 对骶正中动静脉的位置分布及变异进行解剖观察及实际测量其与周围重要结构的位置关系，为临床医师提高腰骶椎前路手术安全性提供必要的参考信息。 方法 收集2008年5月-2011年1月期间因疾病及意外死亡者新鲜人体尸体标本30例，对其进行解剖学研究，观察并测量骶正中动、静脉的发出点与走行，骶正中动、静脉的数量与缺失情况，以及骶正中动、静脉间的相互走行关系。 结果 ①骶正中动脉在主动脉发出以及走行的位置相对固定，无明显多支与缺失情况；骶正中动脉均为腹主动脉根部背侧发出，未见发出点位于左右髂总动脉。发出后行于左侧髂总静脉后方，跨过腰5/骶1椎间盘下行。骶正中静脉与骶正中动脉伴行的情况占总数的60.0%；②骶正中静脉多支常见，没有发现有骶正中静脉的缺失。1支的占总标本数的66.7%，2支的占30.0%，3支的占3.3%。 结论 当选择分叉下入路，应该特别注意骶正中动静脉的解剖位置。动脉的变异相对较小，而静脉的变异程度非常大，发出点变异，多支的情况多见，这些原因都造成了静脉容易损伤的原因，在手术中应该特别注意。【Abstract】 Objective To investigate the clinical significance of anatomical features of middle sacral artery and vein for lumbar-sacral spinal surgery. Methods We carried out anatomical research on 30 cadavers caused by diseases or accidents collected between May 2008 and January 2011. We dissected the vascular system anterior to lumbar vertebrae to learn their characteristics. The initial point of middle sacral artery and confluent point of veins, and the numbers of, and the companion relationship between middle sacral arteries and veins were chosen as the indexes to be measured. Results The middle sacral arteries started from the aorta, and their locations were relatively fixed without absence or multi-branches. All the middle sacral arteries derived from the dorsal side of abdominal artery root, and were not started from the common iliac artery. Then, the sacral arteries went at the back of left common iliac vein, and went down after traversing the inter-vertebral disk between the fifth lumbar and first sacral vertebra. About 60% of the middle sacral veins were accompanied with the arteries. Multi-branches of the middle sacral veins were frequently seen, and no absence was observed. One-branch, two-branch and three-branch middle sacral veins occupied 66.7%, 30.0% and 3.3% respectively out of the total. Conclusions When choosing downward branch approach during the operation, we should pay special attention to the anatomical locations of the middle sacral arteries and veins. Compared with the arteries, there are greater variations of the veins including variations of the confluent point and branches which can cause the veins to be quite vulnerable.
