Evaluation of a water-soluble contrast agent for the conservative management of adhesive small bowel obstruction in pediatric patients.

BACKGROUND/PURPOSE: The diagnostic and therapeutic benefits of a commercial water-soluble contrast agent (Gastrografin) in pediatric patients with adhesive small-bowel obstruction (ASBO) are controversial. The aim of this study was to assess the therapeutic value of Gastrografin in the management of ASBO in children after unsuccessful conservative treatment. METHODS: Medical records from patients with uncomplicated ASBO managed at Cathay General Hospital, Taipei, Taiwan between January 1996 and December 2011 were retrospectively reviewed. All children ≤18 years of age with clinical evidence of ASBO were managed conservative treatment, unless there was suspicion of strangulation. Patients who did not improve after 48 hours of conservative treatment were administered Gastrografin. RESULTS: Twenty-four patients with 33 episodes of ASBO were analyzed. Of those, there were 19 episodes of ASBO that failed to respond to the initial conservative management, and 16 (84%) responded well to Gastrografin administration thereby abrogating the need for surgical intervention. There were neither complications nor mortality that could be attributed to the use of Gastrografin. CONCLUSION: This preliminary study suggested that the use of a water-soluble contrast agent in ASBO is safe in children and useful for managing ASBO, particularly in reducing the need for surgery when conservative treatment fails. However, larger prospective studies would be needed to confirm these results.

Conservative treatment of adhesive small bowel obstruction in children: a systematic review.

OBJECTIVE: To assess the effectiveness of conservative treatment for adhesive small bowel obstruction (ASBO) in children. DESIGN: Systematic review of studies involved children with ASBO who received initial conservative/non-operative treatment. SETTING: The search was performed in April 2013 using PubMed (see online supplementary file 1), current contents, and the Cochrane database. PARTICIPANTS: Children with ASBO. INTERVENTIONS: Conservative treatment included nasogastric decompression, parenteral fluids and correction of electrolyte and fluid imbalance. PRIMARY OUTCOME: Treatment success. SECONDARY OUTCOMES: Length of hospital stay and the time to first feeding after hospital admission. RESULTS: 7 studies (six retrospective, one prospective), involving 8-109 patients (age: 1 month to 16 years) treated conservatively, were included in the review. The nature of conservative treatment was generally consistent between studies (nasogastric decompression, parenteral fluids and correction of electrolyte and fluid imbalance), although patients in one study also received Gastrografin. The rate of conservative treatment success ranged from 16% to 75% among the five studies, but one trial showed 0% successful rate. The hospital length of stay ranged from 3 to 6.5 days for conservative treatment (vs 10.2-13 days for operative treatment). The time to first feeding ranged from 31 to 84 h for conservative treatment. CONCLUSIONS: In conclusion, in the majority of cases, conservative treatment is an effective means of managing ASBO in children.

Clinical manifestations in children with ruptured appendicitis.

OBJECTIVES: Appendicitis is the most common abdominal condition leading to urgent surgery in children. With the goal of identifying signs and symptoms that will allow prompt diagnosis of rupture of the appendix and thus decrease associated morbidities, our aim was to determine factors associated with ruptured appendicitis in children diagnosed with appendicitis. METHODS: The medical records of children aged 17 years or younger with a postoperative diagnosis of acute appendicitis treated at Cathay General Hospital, Taipei, Taiwan, from January 2002 and May 2009, were retrospectively reviewed. The patients were divided into with and without ruptured appendicitis. RESULTS: Of the 228 patients, 140 had a postoperative pathological diagnosis of a nonperforated appendix, and 88 had a diagnosis of perforated appendix, resulting in a perforation rate of 38.6%. Younger age, longer duration of abdominal pain, fever, muscle guarding, and elevated C-reactive protein level were significantly associated with a perforated appendix. CONCLUSIONS: Younger age, longer duration of abdominal pain, fever, muscle guarding, and elevated C-reactive protein level are significantly associated with a perforated appendix; these factors should be closely considered in the evaluation of individuals with suspected appendicitis.

Choledochal cysts in infants and children: experiences over a 20-year period at a single institution.

This analysis was undertaken to compare the clinicopathological features of infants with choledochal cysts to those of older children with these entities and to evaluate the surgical outcomes for both subject groups. The medical records of all children admitted to the Cathay General Hospital with choledochal cysts over a 20-year period were retrospectively reviewed. Twenty-five subjects were included and divided into the infant (<1 year at presentation; 8 subjects) and classical pediatric (1-18 years at presentation; 17 subjects) groups. Anatomical subtypes were: IA (16), IC (6), and IVA (3). The median biliary amylase value was markedly elevated for the pediatric group but not for the infant group. Most (82.4%) patients in the pediatric group, but none in the infant group, presented with abdominal pain. Jaundice and clay-colored stool were present in all patients in the infant group but only 35% of those in the pediatric group. All patients underwent choledochocystectomy and Roux-en-Y hepaticojejunostomy with good outcomes. Neonates/infants with choledochal cysts present differently from older children with these entities. Amylase measurements may serve to distinguish biliary atresia with cystic dilatation from choledochal cyst in neonates/infants. Prognosis following radical cyst excision and reconstruction with Roux-en-Y hepaticojejunostomy is excellent.
