ABSTRACT
Objective To explore the necessities and clinical value of acute intestinal obstruction with com-puted tomography of whole abdomen in over 80 years old patients.Methods 50 patients with acute intestinal obstruc-tion were diagnosed in department of emergency surgery and underwent the abdominal CT examinations.The clinical data,CT and surgery pathology of all patients were compared and analyzed.Results All cases were verified by surgi-cal operation and pathological diagnosis,including colorectal cancer(n =21)and incarcerated abdominal external her-nia(n =21),appendicitis(n =2),adhesive intestinal obstruction(n =2),intestinal volvulus (n =2),and intestinal intussusception(n =1)and stercoral intestinal obstruction(n =1),12 cases were accompanied by bowel necrosis and perforation.12 patients were treated by laparoscope surgery,38 cases by open laparotomy,48 patients acquired good recovery,and 2 cases died from extensive bowel necrosis and multi -organ failure.Conclusion CT examination in whole abdomen could rapidly and accurately diagnose the cause of intestinal obstruction,evaluate complications and risks,so as to provide reasonable treatment choice and time,making patients acquired the effective effects as soon as possible,reducing the bad consequences.
ABSTRACT
Objective To establish a model of cervical spondylosis in rats. Methods Sixty SD rats (four months old) were ran-domly divided into control, muscle imbalance and posterior column instability group, ten rats in each group. Then the degeneration of X-ray film and motion function were evaluated by oblique board test. Results After analyzed the cervical films of control groups, the nature curve still existed, vertebral clearance had no abnormal. No ostensis spurs or ossifies in Luschka joint and joint processes were found. But in mus-cle imbalance and posterior column instability groups, the nature curve was disappeared or stiff, vertebral clearance were stenosis, osteosis spur formed, ossify or sclerosis emerged in Lnschka joint and joint process. Compared with control group in oblique board test, the muscle force decreased in muscle imbalance and posterior column instability group. There were no statistic significant difference between 2 and 4 months of control group, and also no difference in muscle imbalance and posterior column instability group, but there were significant differ-ence in 2 and 4 months of muscle imbalance and posterior column group. Conclusion Not only cervical posterior column instability but also muscle imbalance could result in cervical spendylosis, both muscle force balance and posterior column were important factors in maintaining spine stability.
