Abstract:
Objective:To analyze and summarize the clinical features in children with recurrent intussusception.Methods:This retrospective cohort study collected the clinical data of 126 children with recurrent intussusception who were admitted to the Children′s Hospital of Zhejiang University School of Medicine due to "abdominal pain, paroxysmal crying, vomiting, bloody stools" from January 1, 2015 to November 30, 2019. The clinical manifestations of recurrent intussusception between ≤3 years old group and >3 years old group were compared, the etiology and age characteristics of pathologic lead points (PLP) were analyzed, and the clinical characteristics of PLP group and non-PLP group were also compared. The χ 2 test and Mann-Whitney U test were used to compare the differences between groups. Results:A total of 126 children with recurrent intussusception were included, of whom 76 were males and 50 were females, with the age of 2.9 (1.7, 5.1) years. The proportion of children aged more than 1 year was 87.3% (110/126), and 48.4% (61/126) more than 3 years. Clinical manifestations mostly lacked the typical triad of symptoms. The percentage of paroxysmal crying in ≤ 3 years old group was significantly higher than that in >3 years old group (52.3% (34/65) vs. 24.6% (15/61), χ 2=10.17, P=0.001), while the percentage of abdominal pain was significantly lower than that in the >3 years old group (46.1% (30/65) vs. 75.4% (46/61), χ 2=11.25, P=0.001). The rate of positive ultrasound examination was 17.5% (22/126), and 63.6% (14/22) of them were diagnosed. The positive rate of CT examination was 4/13, of which 2 cases were diagnosed. In this study, 37 children were diagnosed with PLP by colonoscopy, laparoscopy or laparotomy, and 89 children were found without PLP. The positive rate of PLP in >3 years old group was significantly higher than that in ≤3 years old group (37.7% (23/61) vs. 21.5% (14/65), χ 2=3.96, P=0.046). Meckel′s diverticulum and juvenile polyp were the main contributors of PLP in ≤3 years old group, accounting for 7/14 and 3/14 respectively, while lymphoma and juvenile polyp accounted for 34.8% (8/23) and 26.1% (6/23), respectively in >3 years old group. Compared with non-PLP group, PLP group had higher age (5.2 (1.6, 6.7) vs. 2.7 (1.8, 4.2) years, Z=-2.26, P=0.01). However, there were no significant differences in gender and recurrence frequency between the two groups (both P>0.05). Conclusions:Recurrent intussusception is more common in children more than 1 year old, and has a wide spectrum of non-specific clinical presentations. Imaging examinations can be used to identify PLP. The most recurrent intussusception is idiopathic, but the presence of PLP should be alerted for, such as Meckel′s diverticulum, lymphoma and juvenile polyp. Colonoscopy sometimes is necessary, surgical exploration and treatment should be carried out in time.
