Change of the Clinical Aspects and Management of Childhood Intussusception

PURPOSE & METHODS: Nonoperative reduction of childhood intussusception is the treatment of choice. However, few techniques of nonoperative reduction are available. When used, nonoperative reduction can be successfully completed by a radiologist. In this study, we analyzed 637 cases of childhood intussusception diagnosed and treated by ultrasound-guided saline enema reduction (UGSER) over nine years at Ewha Womans University Mokdong Hospital. We compared the results of 76 cases surgically treated after UGSER (US group) with 84 cases surgically treated after barium enema reduction in 1980s (BE group). RESULTS: The success rate of the saline reduction was 88.1%. The risk factors associated with surgery were the patient's age, symptom duration and the type of intussusception. The rate of bowel resection was 32.9%. Patients less than six months old and a pathologic lead point (PLP) on the US were risk factors for bowel resection. There were no significant differences in age, gender and the number of PLPs between the US and BE groups. The number of patients with a spontaneous reduction was greater in the BE group and bowel perforation occurred only in the US group. The bowel resection rate was significantly higher in the US group. However, the median hospital stay was significantly shorter in the US group. CONCLUSION: UGSER is reliable and safe in childhood intussusecption. Moreover, it has a high success rate and is easy to perform. The surgeon, without the need for a radiologist, performs this procedure from diagnosis to treatment. In addition, it might help avoid invasive surgery.

A Comparative Study of Non-operative Management in Childhood Intussusception

PURPOSE: Intussusception is one of the most common causes of intestinal obstruction in children under the age of 2 years, especially in male. In this study, we compared the results of pressure reductions for various treatment methods and identified the factors related to reduction failure. METHODS: From Jan. 1996 to Dec. 1997, 87 barium reductions and 127 air reductions were performed for childhood in tussusception. Success rates of these non-operative managements and factors affecting those rates were analyzed. RESULTS: 1) When only ileocolic intussusceptions were considered in order to exclude the effect of different type of intussusceptions, the success rate for air reduction (AR) was 83.5%, which was significantly higher than 71.8% in barium reduction (BR). 2) Factors affecting reduction failure were history of preceding upper respiratory infection, fever (> or =38oC) and symptom duration in BR, and abdominal distension, leukocytosis (> or =10,000/mm3), and symptom duration in AR. 3) Bowel perforations were occurred in 3 cases of AR, but all of these cases showed bowel wall infarction requiring bowel resection, and complications due to perforations were minimal. There were no BR-related complications in BR. 4) Intussuception recurred in 7.4% of all cases; 4.9% after BR, 9.3% after AR. The mean intervals between previous reduction and recurrence were 37.0 (range 1-88) days in BR and 64.3 (range 2-283) days in AR. Recurrences occurred within 48 hours after reduction in 2 cases of BR and in 3 cases of AR. CONCLUSION: Compared with conventional barium reduction, air reduction had a relatively higher success rate in managing childhood intussusception, in spite of a slightly higher risk of bowel perforation. However, perforation did not significantly affect the clinical course. Therefore, air reduction is one of the good alternative of conventional barium reduction for managing childhood intussusception.

A Comparison of Air Reduction and Operation in Childhood Intussusception

PURPOSE: Intussusception is one of the most common cause of childhood intestinal obstructions. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. METHODS: In order to evaluate the factors contributing to air-reduction failure, we reviewed cases of childhood intussusception admitted via the ER and managed by air enema reduction from 1994 to 1998. They were divided into two groups and compared retrospectively by using medical records. Group I was the operation group after air-reduction failure, and group II was the air-reduction group. RESULTS: In 319 cases (279 patients), group I consisted of 112 cases (110 patients), and group II consisted of 207 cases (169 patients). No differences in age, sex, body weight, location of intussusception, laboratory findings (leukocytosis and thrombocytosis), presence of bloody stool, and body temperature were noted between the two groups. Factors significantly contributing to air-reduction failure were duration of symptoms, type of intussusception and a few physical findings (abdominal distension, palpable mass, lethargy, and vomiting). The recurrence rate of group I was significantly lower than that of group II, and most recurrences developed in the first postoperative month. CONCLUSION: Childhood intussusceptions of a non-ileocolic type with longer durations of symptoms and severe clinical findings have a higher chance of air-reduction failure.
