颈前路减压植骨融合与Bryan人工颈椎间盘置换疗效比较

目的探讨颈椎前路减压植骨融合术(anterior cervical decompression and fusion,ACDF)与Bryan人工颈椎椎间盘置换术(artificial cervical disc replacement,ACDR)两种手术方式用于治疗脊髓型颈椎病及神经根型颈椎病的近期和远期疗效。方法系统分析我院2010年11月至2012年11月70例(70个节段)脊髓型或神经根型颈椎病患者病例资料,将70例(70个节段)脊髓型或神经根型颈椎病患者,通过随机数字表法随机分为ACDF组(35例)及Bryan组(35例)。通过分析术前及术后随访12个月的Odom's标准评分、活动度(range of motion,ROM)、日本骨科协会(Japanese orthopaedic association,JOA)、健康调查简表(the MOS item short from health survey,SF-36)及颈椎残障功能指数(neck disability index,NDI)观察指标的差异,同时对随访12个月的上述各项指标进行两组间比较,比较两者疗效,分析两种术式的优点及他们产生的问题。结果两种手术方式都能取得明确疗效,治疗后患者症状明显缓解(P0.05),两种术式在创伤、出血量等方面差异性不显著(P0.05);JOA评分及SF-36评分两者差异性不显著(P0.05);而在12个月随访ROM评估及NDI比较有差异,Bryan组数据优于ACDF组,差异具有统计学意义(P0.05);Bryan组在Odom's评分中因减压不彻底及异位骨化,有2例等级为差,ACDF组则为0例。结论 Bryan人工颈椎椎间盘置换术在减少颈椎临近节段退变上优于ACDF,短中期疗效优于ACDF,但Bryan人工颈椎椎间盘置换术同时存在减压不彻底及异位骨化等并发症,远期疗效不如ACDF。     

老年非心脏手术患者术前高敏C反应蛋白与术后心脏不良事件相关性的研究

Objective To investigate the relevance between level of preoperative high-sensitivity C-reactive protein(hsCRP) and the occurrence of postoperative adverse cardiac events in elderly patients underwent noncardiac surgery. Methods 49 patients of more than 65 years that had undergone elective noncardiac surgery were enrolled in the study. And all patients were conformed to the standards of "classification of risk factors for clinical history", content of "Guidelines on Preoperative Cardiovascular Evaluation for Noncardiac Surgery" established by the ACC/AHA .The patients were divided into two groups based on the preoperative hsCRP level:A group:hsCRP ≤ 3mg/L group (n=21) and B group: hsCRP>3mg/L group (n=28). General clinical characteristics of patients were recorded before operation, and 24 hours dynamic ECG was monitored a week prior to and after the operation. All patients taken measures of analgesia after surgery. The incidence of postoperative adverse cardiac events and the hospitalized days was recorded. The distinctions between two groups were analyzed regarding the occurrence of adverse cardiac events and hospitalized days after operation. Results 19 patients had postoperative myocardial ischemia; 4 cases in A group and 15 cases in B group. 7 patients suffered other postoperative adverse cardiac events, including 1 case in A group and the others in B group. There was statistically significant difference considering morbidity of myocardial ischemia in postoperation between the two groups, but there was no statistically significant difference about incidence of other adverse cardiac events and the length of stay in postoperation. Indexes about serious degree of myocardial ischemia:total depression time is(43.5±5.82 )min in A group, is( 135.0±81.2)min in B group. The depression times is(5.2±2.5 )in A group, is( 8.8±3.0)in B group.The longest depression time is( 23.7±9.2)min in A group, is( 84.3±54.1 )min in B group.Total ischemia burden is( 170.1 ±88.8 )mm· min-1 ·24h-1 in A group, is (311.3± 118.8 )mm· min-1 ·24h-1 in B group.There was statistically significant difference between the two groups. Conclusion Level of preoperative hsCRP>3 mg/L was relevant to the incidence of the most common postoperative adverse cardiac events--myocardial ischemia in elderly patients and level of preoperative hsCRP >3 mg/L was one of the risk factors of postoperative myocardial ischemia;Determination of preoperative hsCRP level may improve cardiovascular risk scoring system.

Abstract：

Objective This study is to analyse the clinical feature and risk factors of morbidity after pulmonary resection for lung cancer in patients older than 70 years. Methods The clinical records of 222 patients older than 70 years who had undergone pulmonary resection for their lung cancer was reviewed. The patients were divided into 3 groups: group Ⅰ including the patients who had severe postoperative complications, group Ⅱ including the patients who had mild complications and group Ⅲ including the patients who had no complications. Moreover, the definitions were made that group A1 = group Ⅰ+ Ⅱ , group B1 = group Ⅲ, group A2 = group Ⅰ and group B2 = group Ⅱ + Ⅲ. Univariate analyses and multivariate binary logistic regressions relating postoperative morbidity to risk factors were performed between the group Al and Bl, A2 and B2, resulting in the identification of the independent risk factors for overall morbidity and major morbidity. Results Preoperative comorbidity was recorded in 161 patients (72.5%). Lobectomy (64.9% ) was the predominant surgical procedure. The median number of dissected LN was 14, with the range of 0 to 57. The overall morbidity was 63.5% , including major morbidity of 13.5%. Perioperative mortality was 1.8% (4 cases). The results of binary logistic regression analyses indicated that the independent risk factors for overall morbidity were preoperative weight loss (P =0.020), ASA score (P＜0.001), MVV (% predicted) (P=0. 020 ) and the number of dissected LN ( P = 0.004 ). The independent risk factors for major morbidity were ASA score ( P =0.003), MVV (% predicted) (P= 0.018) and the location of tumor (P=0.007). Conclusion Preoperative weight loss and numbers of dissected mediastinal lymph nodes were risk factor for lung cancer patients older than 70 years, Proper perioperative management for the elderly patients with high ASA score, low MVV (% predicted) or central tumor, could reduce the major postoperative morbidity.

术前介入化疗对胰头癌淋巴结转移的影响

Objective To evaluate the efficacy of preoperative regional intra-arterial chemotherapy (RIAC) in the treatment of resectable pancreatic head carcinoma. Methods The clinical data of 50 patients with resectable pancreatic head carcinoma who had been admitted to the Research Institute of Pancreatic Diseases of Fudan University from December 2006 to July 2007 were retrospectively analyzed. Patients were randomly divided into2 groups (n =25 in each group): patients in group A were treated with preoperative RIAC followed by regional pancreaticoduodenectomy, and patients in group B were treated with surgical procedure routinely. The lymphatic metastases in the 50 specimens of pancreatic head carcinoma were detected by histological examination with hematoxylin and eosin (HE) staining, and lymphatic micrometastases were detected by immunohistochemical method with staining of cytokeratin AE1/AE3 in 10 specimens with negative HE staining of the lymph nodes in each group. Results There was no significant difference in the incidence of complications, the length of hospital stay and the 1-, 2-year survival rates between the 2 groups (χ2 = 0.12, 2.88, P > 0.05). The incidence of positive lymph node metastasis in group A was 7.1% (52/734), which was significantly higher than 22.1% (118/532) in group B (χ2 = 60.01, P < 0.05). The incidence of lymphatic micrometastasis was 9.4% (30/319) in group A, and 9.1% (23/252) in group B, with no statistical difference between the 2 groups (χ2= 0.01, P > 0.05). Conclusions Preoperative RIAC is helpful in improving the prognosis of patients with resectable pancreatic head carcinoma by reducing the incidence of lymphatic metastasis and decreasing tumor stage.

Objective To investigate the value of modified pancreatoduodenectomy in the treatment of ampullary carcinoma by comparing the efficacy of pancreatoduodenectomy with preservation of ascending portion of duodenum and that of Whipple procedure. Methods The clinical data of 133 patients with ampullary carcinoma who had been admitted to the Qilu Hospital from 1990 to 2006 were retrospectively analyzed. Of the 133 patients, 88 received Whipple procedure (group A) and 45 received pancreatoduedenectomy with preservation of ascending portion of duodenum (group B). The preoperative condition of the patients and short- and long-term efficacy of the 2 procedures were compared by Fisher exact probability, t test, chi-square test, Kaplan-Meier survival curve and Log-rank test, and the differences between the efficacy of the 2 procedures were compared. Results The operation time, time of gastrointestinal function recovery, hospital stay and ratio of patients with blood transfusion were (366±111) minutes, (7.4±1.4) days, (24±9) days and 76% (67/88) in group A, and (325±32)minutes, (4.3±1.4)days, (31±14)days, 42% (19/45) in group B, with significant difference between the 2 groups (t = 2.34, 2.08, 1.98 ; χ2 = 14.99, P < 0.05). The medium survival time of patients in groups A and B were (19.0±1.5)months and (16.9±1.7) months, with no significant difference between the 2 groups (χ2 = 0.46, P > 0.05). There was no significant difference in the occurrence of postoperative complications between the 2 groups (P > 0.05). Conclusions Pancreateduodenectomy with preservation of ascending portion of duodenum can be applied for patients with ampullary carcinoma.     

代谢综合征与胃癌患者术后短期疗效的关系研究

Objective To investigate the incidence of metabolic syndrome (MS) in patients with gastric cancer, and to explore the relationship between MS and the tumor site and the influence of MS on surgical procedure and short-term outcomes of patients with gastric cancer. Methods The clinical data of 639 patients with gastric cancer who were admitted to the Affiliated Hospital of Qingdao University from January 2006 to June 2008 were retrospectively analyzed. Patients with MS were in the MS group ( n= 64) and those without MS were in the control group ( n = 575 ). The surgical and postoperative complications were reviewed and the tumor site, intraoperative conditions and short-term outcomes between the two groups were analyzed. All data were analyzed using the chi-square test or t test. Results The incidence of MS in patients with gastric cancer was 10.0% (64/639).The incidence of MS in female patients was 14.4% (27/188), which was significantly higher than 8.2% (37/451)of male patients ( χ2= 6.265, P < 0.05). The operation time of the MS group was ( 185 ± 133 ) minutes, which was significantly longer than ( 168 ± 50) minutes of the control group ( t = 2. 126, P < 0. 05 ). The number of lymph nodes dissected in the MS group was 18 ± 11, which was significantly lower than 21 ± 11 of the control group ( t = 2. 125, P < 0.05 ). The postoperative period of fever of the MS group was (3.0 ± 1.4) days, which was significantly longer than (2.5 ± 1.4) days of the control group (t = 2. 433, P < 0.05 ). The incidence of postoperative complications of the MS group was 31.3% (20/64), which was significantly higher than 14.3% (82/575) of the control group ( χ2 = 12.291, P < 0.05 ). The length of hospital stay of the MS group was ( 19 ± 11 ) days,which was significantly longer than ( 16±11 ) days of the control group ( t = 2. 141, P< 0.05 ). The mortalities of MS group and control group were 0 and 0. 5% (3/575), respectively, with no significant difference ( χ2 = 0.000,P >0.05). Condusions A low prevalence of MS is found in patients with gastric cancer. However, patients with gastric cancer complicated with MS may present with prolonged surgical procedure, reduced amount of lymph nodes dissected and increased incidence of postoperative complications, hospital stay and costs. Perioperative management of patients with gastric cancer complicated with MS should be paid more attention.

目的通过与颈前路减压植骨内固定术治疗患者比较,探讨应用Discover人工颈椎间盘置换治疗颈椎病的早期效果。方法回顾分析2010年3月-2011年3月24例符合选择标准的神经根型和脊髓型颈椎病患者临床资料,按收治时间分为颈前路减压融合组(融合组13例,2010年3月-2010年9月)和Discover人工颈椎间盘置换组(置换组11例,2010年9月-2011年3月)。两组患者性别、年龄、病程、病变分型、病变节段等一般资料比较,差异均无统计学意义(P>0.05),具有可比性。记录手术时间、出血量、术后并发症,采用日本骨科协会(JOA)改善率、颈椎功能障碍指数(NDI)、Odom’s评分评价疗效;置换组于手术前后X线片上测量置换及其邻近节段的过伸过屈、左右侧屈活动度,以及假体偏心距。结果两组患者术后症状均缓解,未出现明显并发症。患者均获随访,融合组随访时间12～18个月,平均15.3个月;置换组随访时间6～12个月,平均9.6个月。术后1、3、6个月置换组NDI均高于融合组(P<0.05),但JOA评分改善率比较差异无统计学意义(P>0.05)。末次随访时融合组Odom’s评分为优6例,良4例,可3例,优良率76.92%;置换组为优9例,良1例,差1例,优良率90.91%;两组比较差异无统计学意义(χ2=3.000,P=0.223)。术后置换组过伸过屈及右侧屈活动度于1个月时明显减小(P<0.05),之后逐渐恢复;左侧屈活动度呈先增加后减少趋势,其中3、6个月时较术前明显增加(P<0.05)。术后置换节段和上位节段左侧屈活动度大于右侧屈(P<0.05),且上位节段左、右侧屈活动度差约为置换节段的2倍;侧屈活动度差与假体偏心距成正相关(P<0.05),且假体偏向侧的侧屈活动度增大,对侧活动度减小。结论 Discover人工颈椎间盘置换术是一种简便、安全且能保留颈椎活动的手术,早期疗效较好。     

Clinical and radiological analysis of Bryan cervical disc arthroplasty: eight-year follow-up results compared with anterior cervical discectomy and fusion

Purpose

Bryan cervical disc arthroplasty has been reported with satisfactory short- and medium-term clinical results. However, the long-term clinical and radiographic outcomes are seldom reported. The purpose of this study was to compare the eight-year follow-up results in patients who underwent Bryan disc arthroplasty with patients received ACDF, and assess the incidence of heterotopic ossification (HO) and its effect on clinical outcome and mobility of the device.

Methods

Thirty-one patients underwent Bryan disc arthroplasty, and 35 patients underwent ACDF were included in the study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS) of neck and arm pain, and the radiographs were used to evaluate the outcomes. The heterotopic ossification (HO) was determined by CT scan and was classified into three subgroups to compare the related effect. Adjacent segment degeneration (ASD) was also observed.

Results

At final follow-up, there were no significant differences in JOA scores between two groups, but the improvement in NDI and neck or arm VAS were significantly greater in the Bryan disc cohort. The range of motion at the index level was 7.0° in Bryan group, while 100 % bone fusion were achieved in ACDF group. HO was observed in 18 (51.4 %) levels. There were more restricted movement of the prosthesis and slight higher rate of axial pain in patients with severe-HO (grade III and IV). Fourteen (28.6 %) levels developed ASD in Bryan group, which was significantly lower than that (58.6 %) in ACDF group.

Conclusions

At eight year follow-up, the clinical and radiographic outcomes of Bryan cervical disc arthroplasty compared favorably to those of ACDF. It avoided accelerated adjacent segment degeneration by preserving motion. However, severe HO restricted the ROM of the index levels and maybe associated with post-operative axial pain.

     

单节段人工颈椎间盘置换与前路融合术的对照研究

 目的 观察比较 Prestige LP人工颈椎间盘置换术和经前路颈椎间盘切除植骨融合术(an terior cervical discectomy and fusion, ACDF)治疗单节段颈椎间盘突出症的临床效果。方法 2008年 1月 至 2010年 3月, 87例单节段颈椎间盘突出症患者接受 Prestige LP人工颈椎间盘置换手术(置换组, 44 例)或 ACDF手术(融合组, 43例)。分别在术前, 术后 1周, 术后 3、6、12及 24个月, 对患者进行疼痛视 觉模拟评分(visual analogue scale, VAS)、日本矫形外科协会(Japanese Orthopedics Association, JOA)脊髓 功能评分和生活质量量表(Short Form-36, SF-36)的评估及影像学评估, 同时记录患者并发症及二次手 术情况。结果 78例患者获得平均 12.4个月(6~24个月)随访。两组患者的颈痛、上肢痛 VAS和 JOA评 分, 术后各随访点较术前均有改善(P0.05)。SF-36躯体评分、精神 评分术后各点较术前有明显上升(P0.05), 融合组融合成功率为 92.1%。置换 组中 3例患者在 3个月时假体有<3 mm的前移, 1例患者在术后第 3天发生脑脊液漏;融合组中 2例患 者发生邻椎病并接受二次手术治疗。结论 单节段 Prestige LP人工颈椎间盘置换术治疗颈椎间盘突出 症, 与 ACDF手术一样使患者症状缓解明显, 且对手术节段及邻近节段活动度影响小。     

A prospective,randomised, controlled multicentre study comparing cervical disc replacement with anterior cervical decompression and fusion

Purpose

Total cervical artificial disc replacement (TDR) simulates normal disc structure, thus avoiding the drawbacks of anterior cervical decompression and fusion (ACDF). This prospective, randomized, controlled and multicentre study aimed to evaluate clinical and radiographic outcomes by comparing cervical disc replacement using Mobi-C disc prostheses with ACDF.

Methods

This prospective, randomized, controlled and multicentre study consisted of 111 patients undergoing single-level Mobi-C disc prosthesis replacement (TDR group, n?=?55) or ACDF (n?=?56) from February 2008 to November 2009 at 11 medical centres across China. Patients were assessed before surgery, at seven days postoperation and one, three, six, 12, 24, 36 and 48 months postoperation. Clinical and neurological outcome was determined by measuring the Japanese Orthopaedic Association (JOA) scores, visual analogue scale (VAS) and Neck Disability Index (NDI). Static and dynamic radiographs were obtained of the cervical curvature, the functional spinal unit (FSU) angle and range of motion (ROM) of the cervical spine, FSU angle and treated and adjacent segments.

Results

A total of 111 patients were included and randomly assigned to either Mobi-C disc prosthesis replacement or ACDF. JOA, VAS and NDI showed statistically significant improvements 48 months after surgery (P?p?>?0.05). ROM in the ACDF group was significantly reduced at one month and remained so throughout the follow-up. By 48-months, more ACDF patients required secondary surgery (four of 56 patients).

Conclusions

Although ACDF may increase the risk of additional surgery, clinical outcomes indicated that both Mobi-C artificial cervical disc replacement and ACDF were reliable. Radiographic data showed that ROM of the cervical spine, FSU angle and treated and adjacent segments were relatively better reconstructed and maintained in the Mobi-C group compared with those in the ACDF group.
