Catheter Rinse And Suction Drainage Treat Esophageal Fistula Caused By Anterior Cervical Spine Surgery

Objective:To discuss the clinical effects of modified open-door laminoplasty for chronic compressive cervical myelopathy. Methods:From January 2010 to December 2013, we retrospectively analyzed the data of 87 cases of chronic compressive cervical myelopathy who underwent expensive open-door laminoplasty in the First Affiliated Hospital of Xinjiang Medical University. Among them,41 cases in the modified group were treated by modified open-door laminoplasty. C7 spinous ligaments and muscle tissue attachment were retained. Door section was C3-C6.46 cases in the control group were treated by traditional C3-C7 expensive open-door laminoplasty. Operative time and intraoperative blood loss were recorded. Japanese Orthopaedic Association (17-score method), cervical curvature Cobb angle, range of motion of cervical vertebra and axial symptom severity were compared and analyzed before treatment and during follow-up after treatment. Results:A total of 87 cases were followed up. Operative time was (82.46±14.80) minutes, and blood loss was (196.3±141.4) mL in the modified group. The operative time was (78.41±15.43) minutes and blood loss was (220.91±128.21) mL in the control group. No significant difference was found between the two groups(P> 0.05). There were no significant differences in the recovery rate of Japanese Orthopaedic Association between the two groups (P>0.05). The proportion of patients with apparent axial symptoms was 17% in the modified group and 46% in the control group, showing that the proportion was significantly higher in the control group than in the modified group (P<0.05). The degrees of cervical curvature loss and cervical activity loss were significantly less in the modified group than in the control group (P<0.05). Door shaft side was healed and no door-reclose was noted during follow-up. Conclusion:Above findings showed that the modified expansive open-door cervical laminoplasty got a good nerve decompression, maintained the integrity of the posterior ligamentous complex structure and function to the most degree, reduced damage to the cervical spine stability mechanism, and retained cervical curvature, cervical activity, and diminished the occurrence of postoperative axial symptoms.
