This study aimed to evaluate the influence of subsidence in patients who performed stand-alone anterior cervical discectomy and fusion (ACDF) by analyzing the long-term clinical and radiological outcomes. This retrospective study enrolled 53 patients with 79 segments with degenerative cervical disease treated with stand-alone ACDF with ≥5 years of follow-up. Segmental angle (SA), cervical sagittal alignment (CSA), subsidence, and fusion were analyzed. Visual analog scale (VAS) scores and neck disability index (NDI) were also evaluated. Subsidence occurred in 24 (45.2%) patients and 38 segments (48.1%) at the last follow-up. The mean VAS score and NDI had improved in both the subsidence and non- subsidence groups. The mean SA at the last follow-up had increased to 1.3° ± 8.5° in the subsidence group and to 1.5° ± 5.2° in the non-subsidence group compared with the post-operative SA (P < .001). The overall mean CSA at the last follow-up increased over time in both the groups compared with the post-operative CSA (P = .003). The fusion rate at 1 year after surgery was 86.8% and 82.9% in the subsidence and non-subsidence groups, respectively. However, the differences in the SA, CSA, and fusion rates between the groups were not statistically significant (P = .117, .98, and .682, respectively). Subsidence after stand-alone ACDF occurs to a certain capacity; however, it does not appear to significantly influence the radiological and clinical outcomes if foramen decompression is adequately and sufficiently provided in a long-term follow-up study. In contrast, subsidence appears to positively affect the fusion rate in the short-term follow-up. 相似文献

The cage nonunion may cause serious consequences, including recurrent pain, radiculopathy, and kyphotic deformity. The risk factors for nonunion following anterior cervical discectomy and fusion (ACDF) are controversial. The aim of the study is to investigate the risk factors for nonunion in cervical spondylotic cases after ACDF. We enrolled 58 and 692 cases in the nonunion and union group respectively and followed up the cases at least 6 months. Patient demographic information, surgical details, cervical sagittal parameters, and the serum vitamin D level were collected. A logistic regression was performed to determine the independent predictors for nonunion, which were used for establishing a nomogram. In order to estimate the reliability and the net benefit of nomogram, we applied a receiver operating characteristic curve analysis, calibration curves and plotted decision curves. Using the multivariate logistic regression, we found that age (odds ratio [OR] = 1.16, P < .001), smoking (OR = 3.41, P = .001), angle of C2 to C7 (OR = 1.53, P < .001), number of operated levels (2 levels, OR = 0.42, P = .04; 3 levels, OR = 1.32, P = .54), and serum vitamin D (OR = 0.81, P < .001) were all significant predictors of nonunion (Table (Table3).3). The area under the curve of the model training cohort and validation cohort was 0.89 and 0.87, respectively. The calibration curves showed that the predicted outcome fitted well to the observed outcome in the training cohort (P = .102,) and validation cohort (P = .125). The decision curves showed the nomogram had more benefits than the All or None scheme if the threshold probability is >10% and <100% in training cohort and validation cohort. We found that age, smoking, angle of C2 to C7, number of operated levels, and serum vitamin D were all significant predictors of nonunion.Table 3Univariate and multivariate logistic regression model for predicting nonunion after ACDF.

As the technology of combining with fusion and nonfusion procedure, cervical hybrid surgery (HS) is an efficacious alternative for treatment with cervical spondylotic myelopathy. While studies on cervical alignment between 3-level HS and anterior cervical discectomy and fusion (ACDF) were seldom reported. The effects of cervical imbalance on its related clinical outcomes are yet undetermined as well.Patients with cervical spondylotic myelopathy, who underwent 3-level ACDF or HS, were included to compare cervical alignment parameters after surgery and then explore the relationship between cervical balance and clinical outcomes.Forty-one patients with HS (HS group) and 32 patients who with ACDF (ACDF group) were reviewed from February 2007 to September 2013 with the mean follow-up of 90.3 ± 25.5 (m) and 86.3 ± 28.9 (m), respectively. Cervical alignments parameters including the C2 to C7 cervical lordosis (CL), C2 to C7 sagittal vertical axis, T1 slope. and T1SCL (T1 slope minus CL), and the clinical outcomes like neck disability index (NDI) and Japanese Orthopedic Association (JOA) score were measured and recorded preoperatively (PreOP), intraoperatively, and on the first preoperative day and the last follow-up (FFU). The balance and imbalance groupings were sorted based on the T1SCL: T1SCL≤20°,balance; T1SCL > 20°, imbalance.We found significant improvements (P < .001) in NDI and JOA at intraoperatively and FFU after ACDF and HS, and no difference on cervical alignment and clinical outcomes between the 2 procedures on the basis of intergroup comparisons. By between-subgroups comparisons, however, we found significant differences in CL and T1SCL at PreOP (P < .05). Nonetheless, there was no significant difference on the clinical outcomes between balance and imbalance subgroups at FFU at PreOP (P > .05), indicating that the change of T1SCL was not correlated to NDI and JOA at FFU.Both HS and ACDF groups showed significant clinical improvements after surgery. There was no correlation between cervical balance and clinical symptoms. 相似文献

It was reported imperative on cervical sagittal alignment reconstruction after anterior multilevel procedures with self-locked stand-alone cage (SSC) or anterior cage-with-plate (ACP) system multilevel while there was little knowledge about the relationship on cervical alignment and clinical outcomes.To identify the importance of cervical sagittal alignment after 3-level anterior cervical discectomy and fusion on cervical spondylotic myelopathy with SSC and ACP system.Seventy-seven patients with SSC system (SSC group) and 52 cases with ACP system (ACP group) from February 2007 to September 2013 were enrolled with well-matched demographics. Cervical alignment included C2–7 lordosis (CL), operated-segment cervical lordosis (OPCL), upper and lower adjacent-segment cervical lordosis, range of motion of upper and lower adjacent segment at preoperation, immediate postoperation, and the final follow-up. Clinical outcomes contained the neck disability index (NDI), the Japanese Orthopaedic Association (JOA) score, visual analogous scale (VAS) of arm and neck and adjacent segment degeneration (ASD). Patients were then divided into CL improved subgroup (IM subgroup) and non-improved subgroup (NIM subgroup).There were improvements on CL and OPCL in both groups. The change of CL and OPCL larger in ACP group (P < .05) but upper adjacent-segment cervical lordosis/lower adjacent-segment cervical lordosis and range of motion of upper adjacent segment/range of motion of lower adjacent segment were of no significance. NDI, JOA, and VAS got improvement in both groups at immediate postoperation and the final follow-up while ASD was in no difference between SSC and ACP group. A total of 80 patients (39 vs 41) acquired CL improvement with a larger population in ACP group. There were no differences on the rate of ASD, NDI, JOA, VAS, and their change between IM and NIM subgroup. The changes of CL were not correlated to NDI, JOA, VAS, and their change.SSC and ACP group both provide improved OPCL and efficacy on 3-level cervical spondylotic myelopathy with little impact on adjacent segment. The change of CL is not correlated to clinical outcomes. 相似文献

Pancreatic resections have evolved into safe operations in experienced centers. Technical refinements continue to further improve operating time, intraoperative blood loss, and outcome after these procedures. The dissection of the uncinate process/pancreatic head is one of the critical steps during pancreaticoduodenectomy. This step can be time-consuming, with the possibility of troublesome hemorrhage. This article describes, in a stepwise fashion, the use of endovascular stapler devices that facilitate uncinate process/pancreatic head dissection during pancreaticoduodenectomy. 相似文献

Objective:We designed and performed a network meta-analysis to compare the clinical outcomes among the 5 surgeries—anterior cervical corpectomy and fusion (ACCF), anterior controllable antedisplacement fusion (ACAF), laminoplasty (LP), laminectomy (LC), and posterior decompression with instrumented fusion (PDF)—for patients with cervical spondylosis related to the ossification of the posterior longitudinal ligament (OPLL).Methods:Databases, including PubMed, EMBASE, Cochrane Library, Google Scholar, and Web of Science (firstly available-2019) were selected for literature search. We performed a network meta-analysis with the included studies. A Newcastle-Ottawa scale was employed to assess the study quality of the included studies.Results:Total 23 studies with 1516 patients were included in our analysis. We found that ACCF achieved the most improvement in the Japanese Orthopaedic Association Scores and excellent and good recovery rate, ACAF achieved the best improvement of the improvement rate and lordosis. LP got the best operative time and blood loss.Conclusions:Our results suggested that both anterior (ACCF and ACAF) and posterior (LP, LC, and PDF) procedures have their strengths and weaknesses. Clinicians need to select the most appropriate surgery with a comprehensive consideration of the clinical condition of each patient with OPLL-related cervical spondylosis. 相似文献

To evaluate the clinical efficacy of 1-stage anterior focus debridement, interbody bone graft, and anterior instrumentation and fusion in the treatment of short segment thoracic tuberculosis with paraplegia or incomplete paralysis. A total of 16 adult patients with short segment thoracic spinal thoracic tuberculosis who underwent surgery were enrolled in this retrospective study. All patients received anterior focus debridement, interbody bone graft and anterior instrumentation and fusion. All patients were followed up for 24 to 48 months. Clinical manifestations, laboratory examinations, neurological symptoms, bone fusion and imaging results were analyzed. All patients successfully underwent operations. The symptoms of chest and back pain were alleviated and even disappeared during postoperative 1 to 6 months. There was no recurrence. All patients got bony spinal fusion within postoperative 4 to 8 months assessed by spinal X-ray film. The levels of erythrocyte sedimentation rate and C-reactive protein were significantly decreased from 72.6 ± 27.5 mm/h and 75.7 ± 25.9 mg/L to 15.9 ± 4.6mm/h and 4.7 ± 2.0mg/L at the final follow-up, respectively (P < .05). The thoracic kyphosis angle was also notably decreased from 15.0 ± 3.4° to 9.1 ± 1.9° after operation(P < .05). During the follow-up, the symptom of paraplegia or incomplete paralysis was significantly improved. Neurologic status in all patients was also improved to some extent. The combination of 1-stage anterior focus debridement, interbody bone graft and anterior instrumentation and fusion is an effective and feasible treatment method for short segmental thoracic tuberculosis with paraplegia or incomplete paralysis. 相似文献

Local recurrence after curative anterior resection with principally blunt dissection for carcinoma of the rectum and rectosigmoid 总被引:10,自引:0,他引:10

PURPOSE: The aim of this study was to determine the incidence of local pelvic recurrence of carcinoma of the rectum and rectosigmoid (tumors where the lower edge is 18 cm or less from the anal verge) in a consecutive series of patients operated on by a single surgeon. All patients underwent curative anterior resection and a formal anatomic dissection of the rectum where mobilization was achieved through a principally careful blunt manual technique along fascial planes, preserving an oncologic package. METHOD: During the period April 1986 to December 1997, 157 consecutive anterior resections for carcinoma of the rectum and rectosigmoid were performed by one surgeon (ALP). One hundred thirty-eight (87.9 percent) were curative, and 19 (12.1 percent) were palliative. The mean follow-up period was 46±31.6 (range, 2–140) months. Data were retrospectively collated and computer coded by an independent contracted medical research team. Follow-up data were available on all patients. RESULTS: Four (3.1 percent) of the 131 patients undergoing curative anterior resection had local recurrence. Local recurrences occurred between 16 and 38 months from the time of resection, and the cumulative risk of developing local recurrence at five years was 5.2 percent. All tumors in which pelvic recurrence occurred were high grade, and the probability of developing local recurrence at five years for this group was 13.9 percent, which is significantly higher compared with patients who had average or low-grade tumors (P=0.01). The probability of developing local recurrence at five years for Stage I tumors was 0, Stage II was 5.9 percent, and Stage III was 8.9 percent. In addition, there was a significantly higher incidence of local recurrence in the group of patients undergoing ultralow anterior resection (between 3 and 6 cm from the anal verge) as compared with patients undergoing low or high anterior resection (P=0.03). Local recurrence developed in 3 of 28 (10.7 percent) patients having ultralow anterior resection, 1 of 57 (1.8 percent) patients having low anterior resection (between 6 and 10 cm from the anal verge), and no patients having high anterior resection (above 10 cm from the anal verge). The clinical anastomotic leak rate for curative anterior resection was 7 of 131 patients (5.3 percent). Thirty-seven of the 131 (28.2 percent) required a proximal defunctioning stoma; 35 (41.2 percent) of these were established for low or ultralow anterior resections and 2 for high anterior resection. The overall five-year cancer-specific survival rate of the entire group of 131 patients was 81.8 percent, and the overall probability of being disease free at five years including both local and distal recurrence was 72.9 percent. Three local recurrences occurred in the 101 patients (77 percent) who did not receive any form of adjuvant therapy. One local recurrence occurred in the 18 patients (13.7 percent) who had adjuvant chemoradiation. No recurrence occurred in the 12 patients (9.2 percent) who had adjuvant chemotherapy alone. CONCLUSION: Curative anterior resection for carcinoma of the rectum and rectosigmoid with principally blunt dissection of the rectum in this study is associated with a 3.1 percent incidence and a 5.2 percent probability at five years of developing local recurrence. Evidence from this study indicates that, as with sharp pelvic dissection, a low incidence and probability of local recurrence can be achieved by a principally blunt mobilization technique through careful attention to preservation of fascial planes in the pelvis and removal of an oncologic package with selective rather than routine adjuvant or neoadjuvant chemoradiation.Supported by a research grant from the Cabrini Clinical Education and Research Foundation.Read at The American Society of Colon and Rectal Surgeons' 100th Anniversary and Tripartite Meeting, Washington, D.C., May 1 to 6, 1999. 相似文献
