To study the changes in diagnosis and treatment of pediatric choledochal cyst in the past 10 years, a retrospective analysis was made in 79 children with choledochal cyst, who were admitted into our hospital from 1982 to 1998. Results show that in the past years, the clinical manifestation of choledochal cyst in children have become less obvious for earlier consultation. B-mode ultrasounscanning should be the first choice since it aids in the diagnosis of choledochal cyst as well as its related and complicated diseases. Choledochectomy is the only radical treatment for choledochal cyst in children.
To analyze the causes of failure to reduce acute infantile intussusception with gas enema. 441 cases of acute infantile intussusception in our hospital who failed to be reduced with gas-enema, and underwent the operative therapy were analyzed. Result: 92 cases (20.9%) were intestinal necrosis, 184 cases (41.7%) double intussusception, 27 cases (6.1%) organic pathological changes and 8 cases (1.8%) intestinal perforation caused by gas-enema reduction. All the cases had a successful recovery after surgery. Conclusion: The main causes of failure to reduction with gas-enema were as follows: ①double intussusception, ②intestinal necrosis, ③late for visiting a doctor, ④organic pathological changes, ⑤perforation (in the process of gas-enema reduction). The importance of early diagnosis is emphasized.
Purpose To examine the change of optic disc blood flow in primary open angle glaucoma(POAG) patients after cold provocation test and nifedipine administration． Methods Using Heidelberg retinal flowmetry (HRF),the blood flow of optic disc of glaucoma patients and normal control subjects were measured under basal condition, after cold provocation test,and after nifedipine administration. Results The mean optic disc blood volume and flow of POAG patients reduced from 27.1 and 545.4 to 22.3 and 452.4 after cold provocation test (Plt;0.05),and increased to 29.0 and 579.5 after nifedipine adminstration(Plt;0.05).The changes of mean optic disc blood flow of patients with a history of cold extremities show statistic significance compared with whom without such history (Plt;0.05)). Conclusion The changes of blood flow of optic disc in POAG patients may be influenced by cold stimuli and administration of nifedipine,and the history of cold extremities might be connected with the change of optic disc blood flow in POAG patients.
