Intussusception found in the 1st month of life is rare and usually discussed as one entity, neonatal intussusception, but in fact, includes the intussusceptions occurring both prenatally and neonatally, of which the clinical presentations and results are different. Four full-term babies with prenatal intussusception presenting as intestinal atresia (IA) and three premature babies with neonatal intussusception mimicking necrotizing enterocolitis (NEC) are presented. Prenatal intussusception, as one of the causes of IA produces prominent signs of intestinal obstruction immediately after birth. Preoperative evaluation usually fails to yield a definitive diagnosis, but surgery is usually performed in time and is successful. In neonatal intussusception, full-term infants usually have a pathological lead point and the colon is almost always involved. A barium enema is thus useful in diagnosis. Premature babies, on the other hand, rarely have a colonic component, and the clinical features are insidious and similar to NEC. This results in diagnostic confusion that may lead to a dangerous delay in appropriate surgical correction. A high level of suspicion about this condition in cases diagnosed presumptively with NEC is important. Serial abdominal sonograms may be helpful in the early diagnosis of neonatal intussusception.
From January 1990 to December 1995, a total of 22 patients with primary non-refluxing megaureter were treated in our hospital. The age distribution was 7 days to 8 years. The follow-up period was from 1 to 6 years. Nineteen of these 22 children underwent surgical intervention: 3 were operated upon at the time of diagnosis; the other 16 were initially treated conservatively, but underwent subsequent surgery due to impairment of renal function (13) or breakthrough infections (3). The failure rate for conservative management was about 84% (16/19): only 3 patients treated conservatively showed spontaneous resolution. The surgical success rate was 89.5% (17/19). The pathological change in the ureterovesical junction (UVJ) was adynamic in 13 cases and fibrotic in 6 (including 1 ectopic ureter). The postoperative complications were vesicoureteric reflux in 3 cases, with spontaneous resolution 6 months later, and UVJ stenosis in 1, which was resolved by reoperation. It is concluded that surgery is not necessary in every case, but still plays an important role in most cases. Early surgery can achieve good results and reduce renal damage.
Jejunal leiomyoma should be considered in a child with neurofibromatosis presenting with gastro-intestinal bleeding.
From January 1990 to December 1995, a total of 181 patients underwent reimplantation of 318 ureters for primary vesicoureteral reflux (VUR); 87.8% received bilateral reimplantation. Surgical indications included breakthrough infection (35%), high-grade (> or = IV) reflux (33%), or both (29%). The operative success rate was 99.4% at 3 months postoperatively and 100% ultimately. The complications included: contralateral sequential reflux in 3.9%, postoperative bladder diverticula in 1.1%, postoperative urinary infection in 1.1%, residual reflux in 0.3%, postoperative vesicoureteral stenosis in 0.3%, and slippage of the drainage tube in 0.3% of cases. Two patients had renal failure due to VUR that was proven by renal biopsy (one 4-year-old and one 8-year-old). The incidence of associated anomalies was higher than in the normal population. The average number of hospital admission days was 7.9 (3-63). After 1992, no ureteral stent was left in postoperatively. All patients received prophylactic antibiotics for 3 months postoperatively until the VUR disappeared. The surgical results were satisfactory in this series.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
