RESUMEN
Objective: To explore the anatomical spatial relationship between aorta, superior and inferior vena cava and vertebral body in normal 13-15-year-old adolescents, and to provide evidence for anterior or posterior approach of operation on adolescent. Methods: The normal thoracolumbar CT data of 63 13-15-year-old adolescents in Inner Mongolia were collected, including 15 cases of 13-year-old, 21 cases of 14-year-old and 27 cases of 15-year-old. The serial scanning data of thoracolumbar spine tomography were imported into Mimicsl6. 0 for analysis and measurement in DICOM format. The focus of left transverse process and spinous process was determined as the original 0 point. Measuring the distance of aorta from origin 0 (AO), the aortic-vertebral angle(ot),the distance of the superior vena cava from the origin 0(V,0), the superior vena cava-vertebra body angle(p), the distance of the inferior vena cava from the origin 0(V20), the inferior vena cava-vertebra angle(9). Results: AO,α: 13-year-old(52. 16±3. 21) mm, (1. 89±0. 47)°; 14-year-old(52. 63±2. 28) mm,(-1.91±0. 97)°;15-year-old(57. 57±3. 52)mm, (-2. 47±0. 66) °; V,0,p: 13-year-old(66. 71 ±5. 82) mm, (-5. 14± 1.42)°; 14-year-old(77. 01±2. 89)mm,(-ll. I8±2. 64) °; 15-year-old(78. 54±0. 70)mm, (-20. 61±2. 05) °; V20,9 :13- year-old(62. 69±5. 66) mm, (-23. 85± 1. 92) °; 14-year-old(65. 71 ±5. 39) mm, (- 18. 46±2. 77)°; 15-year-old(75. 98± 8. 49) mm, (-18. 58±2. 09)°.There was significant difference in the distance and angle between large vessels and vertebral bodies between different vertebrae (P<0. 05). Conclusion: Mastering the distance and angle between large vessels and vertebral bodies is helpful to reduce the incidence of vascular injury in the process of spinal nailing.
RESUMEN
Objective To analysis the difference of lymph node cleaning and operative complication rate between thoracoscope surgery and routine thoracotomy on patients with thoracic segment esophageal cancer.Methods A summary of 62 patients with thoracic segment esophageal cancer in Xiaogan Hospital Affiliated to Wuhan University of Science and Technology from August 2012 to August 2014,who were carried with thoracoscope surgery,were randomly chosed and designed as the thoracosc0Pe group,and 62 patients with thoracic segment esophageal cancer over the same period,carried out with routine thoracotomy,were designed as the control group.All the clinical data of the two groups were collected.The total of thoracic lymph node cleaned and the group of thoracic lymph node cleaned were compared between the two groups.The operation time,intraoperative blood loss,chest tube placement time and postoperative hospital duration were collected and compared.All the patients were followed up at least for one year.The incidence of postoperative complications such as pulmonary infection,pneumothorax,atelectasis,recurrent laryngeal nerve injury and anastomotic leakage in the follow-up period were compared.The follow-up time,mortality and recurrence rate were compared.Results The total of thoracic lymph node cleaned(13.36±3.28) and the group of thoracic lymph node cleaned(3.35±0.84) in the thoracoscope group were lower then these of the control group ((14.22± 2.78) and (3.58±0.75)),but with no statistical difference (t =1.57,1.61,P＞ 0.05).The operation time of the thoracoscope group((314.63±38.72) min) were higher then that of the control((217.46±41.54) min),and the intraoperative blood loss ((205.73 ± 114.38) ml),chest tube placement time ((6.83 ± 1.92) d) and postoperative hospital duration((18.47±5.36) d) of the thoracoscope group were remarkably lower then these of the control ((345.72 ±175.62) m1,(10.04±2.41) d,(22.65±6.84) d,t=13.47,5.26,8.20,3.79,P＜0.05).The incidence of pulmonary infection (4.8％ (3/62)) and atelectasis (1.6％ (1/62)) of the thoracoscope group,were evidently lower then these of the control (17.7％ (11/62),1.3％ (7/62),x2 =5.15,4.81,P＜0.05).There was no significant difference in mortality and recurrence ratebetween the two groups during the follow-up period (3.2％ (2/62) vs.8.1％ (5/62),11.3％ (7/62) vs.14.5％ (9/62),x2 =1.36,0.29,P＞0.05).Conclusion There are no significant difference inlymph node cleaning between thoracoscope surgery and routine thoracotomy on patients with thoracic segment esophageal cancer,but thoracoscope surgery can shorten the length of hospital duration,reduce the intraoperative blood loss,chest tube placement time and postoperative complications.So the thoracoscope surgery is a safe and feasible operation for patients with thoracic segment esophageal cancer.
