RESUMEN
Objective To compare the short-term clinical effect of K-Rod pedicle dynamic fixation system and lumbar fusion for multi-ple segmental lumbar degeneration.Methods Between January 2010 and October 2012,56 patients with segmental lumbar degeneration who were accepted K-Rod pedicle dynamic fixation system and posterior lumbar interbody fusion were retrospectively reviewed.The 56 patients were divided into K-Rod and fusion group,28 patients with K-Rod pedicle dynamic fixation system and 28 cases with traditional lumbar fusion and internal fixation.Clinical assessments were based on comparion of Oswestry disability index score ,visual analogous scale (VAS),im-provement rate of low back pain,postoperative lumbar spine X-ray,average operation time and intraoperative blood loss of two groups.Results All of 56 cases were followed up for 12 to 24 months,the difference of Oswestry disability index score and VAS between two groups were not statistically significant(P >0.05),but the difference of average operation time,blood loss and the average length of stay(ALOS)were statis-tically significant(P <0.05),the K-Rod group was superior to the fusion group.Conclusion In the treatment of multiple segmental lumbar degeneration both K-Rod pedicle dynamic fixation system and traditional lumbar fusion can obtain satisfactory short-term clinical effect,but the K-Rod pedicle dynamic fixation system has advantages of less intraoperative blood loss,shorter operation time,postoperative small effects on lumbar spine mobility.
RESUMEN
Objective To learn therapeutic effect of the combined treatment of multiple segmental resection and choledochoscope lithotomy on complex intrahepatic biliary calculi.To provide effective and reliable operation method for the treatment of disease.Methods 213 cases with complex intrahepatic biliary were randomly divided into observation group(117 cases)and control group(96 cases)by random number table method.The control group was treated with multiple segmental resection,the observation group was treated with multiple segmental resection com-bined choledochoscope lithotomy.The postoperative complications of the two groups were observed,and the patients of the two groups were followed up,and the effect of surgical treatment was evaluated.Results The hospitalization time of the observation group was (10.1 ±3.4)d,which was significantly shorter than (13.7 ±4.6)d of the control group (t =6.560,P <0.05).Postoperative 3 -6 weeks residual stone rate of the observation group was 7.69%(9 /117), which was lower than that of the control group,the difference was statistically significant (χ2 =4.099,P <0.05).In both two groups,the average duration of follow -up was (11.2 ±3.9)months.In the observation group,the excellent and good rate of surgery 89.74%(105 /117)was higher than the control group (χ2 =9.154,P <0.05).The postop-erative complication rate of the observation group 18.80%(22 /117)was lower than that of the control group,the difference was statistically significant (χ2 =14.467,P <0.05).Conclusion In the treatment of complex intrahepat-ic biliary calculi,the combined treatment of multiple segmental resection and choledochoscope lithotomy has better curative effect and low postoperative complication rate,with good clinical application value.
RESUMEN
Objective To discuss the short-term clinical effect of K-Rod pedicle dynamic fixation system for multiple segmental lumbar degeneration. Methods From January 2010 to October 2012,28 patients with multiple segmental lumbar degeneration who were accepted K-Rod pedicle dynamic fixation system were retrospectively reviewed. The short-term clinical effect were based on Oswestry disability index score,visual analogous scale ( VAS) ,improvement rate of low back pain,postoperative lumbar hyperextension, hyperbend X-ray film lumbar ROM value ( lumbar flexion mobility) ,average operation time, intraoperative blood loss. Results All of 28 cases were achieved 12 ~24 months follow-up,the difference of Oswestry disability index score and visual analogous scale ( VAS) between 12 months postoperatively and preoperatively were statistically significant,the improvement rate of low back pain was (87. 0 ± 2. 0)%,the average operation time was (99. 6 ± 16. 2) minutes,the average blood loss was (70. 5 ± 31. 5)mL,the average length of stay(ALOS) was (11. 2 ± 2. 6) days after sur-gery. Conclusion K-Rod pedicle dynamic fixation system in the treatment of multiple segmental lumbar degeneration can obtain satisfactory short-term clinical effect.
