Acute appendicitis in the first years of life is an uncommon event. The clinical presentation is often varied and the diagnosis may be overshadowed by other medical conditions.Gastroenteritis is the most common misdiagnosis, with a history of diarrhea present in 33% to 41% of patients. Pain is the most common presenting symptom in children less than 5 years old, followed by vomiting, fever, anorexia and diarrhea. The most common physical sign is focal tenderness(61% of the patients) followed by guarding(55%), diffuse tenderness(39%), rebound(32%), and mass(6%). Neonatal appendicitis is a very rare disease with high mortality; presenting symptoms are nonspecific with abdominal distension representing the main clinical presentation. The younger the patient, the earlier perforation occurs: 70% of patients less than 3 years develop a perforation within 48 h of onset of symptoms. A timely diagnosis reduces the risk of complications. We highlight the epidemiology, pathophysiology, clinical signs and laboratory clues of appendicitis in young children and suggest an algorithm for early diagnosis.展开更多

METHODS: Studies and relevant literature regarding the performance of single-incision laparoscopic surgery vs conventional laparoscopic surgery for appendectomy were searched for in the Cochrane Central Register of Controlled Clinical Trials, MEDLINE, EMBASE and World Health Organization international trial register. The operation time (OR time), complications, wound infection and postoperative day using SILS-A or C-LAwere pooled and compared using a meta-analysis. The risk ratios and mean differences were calculated with 95%CIs to evaluate the effect of SILS-A. RESULTS: Sixteen recent studies including 1624 patients were included in this meta-analysis. These studies demonstrated that, compared with C-LA, SILS-A has a similar OR time in adults but needs a longer OR time in children. SILS-A has similar complications, wound infection and length of the postoperative day in adults and children, and required similar doses of narcotics in children, the pooled mean different of -0.14 [95%CI: -2.73-(-2.45), P > 0.05], the pooled mean different of 11.47 (95%CI: 10.84-12.09, P < 0.001), a pooled RR of 1.15 (95%CI: 0.72-1.83, P > 0.05), a pooled RR of 1.9 (95%CI: 0.92-3.91, P > 0.05), a pooled RR of 1.01 (95%CI: 0.51-2.0, P > 0.05) a pooled RR of 1.86 (95%CI: 0.77-4.48, P > 0.05), the pooled mean different of -0.25 (95%CI: -0.50-0, P = 0.05) the pooled mean different of -0.01 (95%CI: -0.05-0.04, P > 0.05) the pooled mean different of -0.13 (95%CI: -0.49-0.23, P > 0.05) respectively. CONCLUSION: SILS-A is a technically feasible and reliable approach with short-term results similar to those obtained with the C-LA procedure.展开更多

Appendicitis is the most common acute surgical emergency of childhood. Since the original report by Puylaert in 1986, the use of ultrasonography in the diagnosis of appendicitis has been the subject of considerable study. Among the reported diagnostic criteria, the maximal outer diameter (MOD) of the appendix is accepted as the one of the most reliable criteria used to differentiate between a normal appendix and acute appendicitis. However, MOD measurement is subject to inaccuracies because luminal distention by non-compressible, non-inflammatory material such as fecal material, or increased maximal mural thickness due to reactive mucosal lym-phoid hyperplasia, or a medical cause due to a generalized gastrointestinal disease, such as Crohn’s disease, can cause the measurement to exceed the upper limits of normality. The aim of this article is to introduce the spectrum of ultrasonographic findings in the normal andabnormal appendix and eventually to reduce unneces-sary surgery in children.展开更多
