RESUMO
Acute appendicitis is one of the most common acute abdominal diseases in pediatric surgery.Appendectomy is the standard of care for the treatment of acute appendicitis in children and its curative effect is definite.With the improvement of endoscopic techniques, laparoscopic appendectomy has become a mainstream operation in the recent years.However, individual therapy based on disease progression is attracting more and more attention, which has led to new questions.The management of these questions has not formed consensus at present, such as conclusion timing, operative methods, treatment of appendiceal abscess and effect of non-operative management.This review summarizes the treatment progress of acute appendicitis in children.
RESUMO
Objective:To study the feasibility of 3-D reconstruction model in the observation of tetrachlorodibenzo-p-dioxin(TCDD) effected palatal organ development of fetal mouse.Methods:Kunming mice treated 40 ug/kg TCDD by lavage on day 12.5 of pregnancy were used as in the experimental group,isodose corn oil treated in the control group.On day 13.5,14.5 and 15.5 of pregnancy heads of the fetal mice were taken out and fixed.Conventional paraffin serial sections of palatal organ were preparated and dyed by hematoxylin-eosin,images of the palatal organs were collected and photoshop treated,3-D reconstruction of the palatal organ was performed by 3D-DOCTOR software.Results:3-D reconstruction images showed that palatal organs moved from on both sides above the tongue and gradually closed and merged in the control group.In the experimental group,the palatal organs moved from on both sides above the tongue was later than control group,gradually closed,but not merged,formed cleft palate.Conclusion:3D-DOCTOR software reconstruction can be used for the study of the development process effected by TCDD in the pregnant mouse.
