Analysis of clinical characteristics of chronic abdominal pain in children / 中国基层医药

ABSTRACT

Objective To analyze the clinical prevalence,distributed characteristic of different ages,clinical characteristics and pathogenic factors of chronic abdominal pain in children.Methods A database in which outpa-tient and inpatient of abdominal pain during 2 -14 years old were collected from January 2011 to December 2015 was established by utilizing HIS system.A statistical analysis was made in age,sex,onset time,time of duration,mesenteric lymph node status and surgical situation.Results A total of 13 256 times abdominalgia were enrolled from January 2011 to December 2015.7 390 patients were diagnosed as unexplained abdominal pain,including 1 005 patients (13.59%)were diagnosed as chronic abdominal pain.A male -to -female ratio was 1.061.The average age was 6 years(ranged 2 -14 years).The average age of the boys was (6.02 ±2.87)years,which of the girls was (5.93 ± 2.79)years,there was no statistically significant difference between them(t =0.47,P =0.63).The peak age of chro-nic abdominal pain in children was mainly from 3 to 7 years old.The incidence decreased with age increased.The average time of duration was (16.70 ±11.69)months,that of the boys was (17.39 ±12.12)months,and that of the girls was (15.96 ±11.19)months,there was statistically significant difference between them(t =1.93,P =0.05). Mesenteric lymphadenectasis was detected in 731 patients(72.74%).The age constituent ratio decreased with age increased.The peak age of the prevalence coincided with peak age of the mesenteric lymphadenectasis.21 patients underwent surgical procedures,organic lesions accounted for 2.08%.Conclusion The peak age of the prevalence of chronic abdominal pain in children is mainly from 3 to 7 years old.Potential organic causes are rarely linked to chronic abdominal pain in children.Most of them are functional abdominal pain.The appendix and mesenteric lymphadenecta-sis might play an important role in children with chronic abdominal pain.The therapeutic aim of CAP in children is to make the children back to their normal life by exclude the organic causes and relieve their pain.The natural history of chronic abdominal pain suggests that symptoms remit spontaneously with increasing age.
