Meconium ileus is one of the commonest causes of distal small bowel obstruction in neonates. Within the last six years at our hospital two newborns presented with identical signs and symptoms of meconium ileus. Abdominal x-rays showed distal small bowel obstruction with ground glass opacity in the right lower quadrant. Gastrografin enema in both cases demonstrated a microcolon, but there was no reflux of this contrast material into the terminal ileum. Laparotomy in both babies revealed atresia of the ileocaecal valve with dilatation of the terminal ileum loops which contained normal meconium. Ileocolic resection was carried out in both neonates. Sweat chlorides and eventual recovery were normal. Pathology in one of the specimens showed muscularis passing across the atretic area with a telescoped pattern of the muscularis propria suggesting intussusception in utero. Although the presentation of a newborn may be that of meconium ileus, the fact that the Gastrografin enema is unable to enter the terminal ileum in a retrograde fashion should be an indication for immediate laparotomy rather than persisting in this mode of treatment. It is obvious that occasionally the radiological diagnosis of meconium ileus is incorrect.

Intussusception associated with Yersinia pseudotuberculosis infection was developed in three boys; two of them had a history of drinking untreated water. All intussusceptions were localized at the ileocolic region, and all patients completely recovered with Gastrografin enema and supportive treatment without complication and operation.

Cystic fibrosis (CF) is a genetic disorder affecting approximately one in 2,500 births in the United States. Nearly 1% of patients with CF will develop intussusception, which is commonly ileocecal and felt to be secondary to inspissated feces. These patients generally present before the age of ten. Once the diagnosis of intussusception is confirmed on ultrasound or CT, surgery has been the mainstay of treatment in this patient group. We propose the use of air and contrast enemas as effective and beneficial non-operative approach in these patients. Clinical and imaging findings in four children with known CF who presented with intestinal intussusception, average age 13.25 +/- 5.3 years (range 8-18 years) were reviewed. Patients were diagnosed using ultrasound (n = 3) or abdominal CT (n = 1). All patients suffered from an ileocolic intussusception. Air and Gastrografin(R) enemas were used in an attempt to reduce the intussusception. There were six separate successful intussusception reductions in four patients. Three patients required multiple attempts (2.3 +/- 0.6). Air enemas were used initially in all cases. Gastrografin(R) was used successfully following the failure of air enema in one patient. One patient suffered three separate intussusceptions over a period of 18 months, which were all successfully reduced using air. There were no complications and the patients tolerated the procedure well. Intussusception is an uncommon but serious complication in children with CF. While surgical reduction has been the mainstay of treatment for these patients, we demonstrated that reduction of an intussusception using air or contrast can be accomplished safely, without anesthesia, and should be the initial treatment option.

A 7-kg 8-month-old boy was transferred to our institution after failed enema reduction of intussusception elsewhere. During the redo intervention using a 6-fold-diluted solution of Gastrografin with water as contrast medium, the bowel was perforated. Urgent surgical repair was planned and preoperative examination revealed serum sodium of 137 mEq x l(-1). On arrival in the operating room, the patient presented abdominal distension, drowsiness and tachypnea. His trachea was intubated and anesthesia was maintained with sevoflurane. Arterial blood examination immediately before the surgery (approximate by 80 minutes after the previous blood test) showed the following findings: pH 7.27, base excess -8.5 mEq x l(-1) and sodium 122 mEq x l(-1). Watery ascites estimated at 450 ml was evacuated upon a peritoneal incision. At termination of anesthesia, serum sodium recovered to 133 mEq x l(-1), resulting from replenishment of electrolytes and sodium bicarbonate administration. The patient became fully awake and his trachea was extubated in the operating room. Gastrografin has osmolarity of 1,900 mOsm x l(-1), containing sodium of 158 mEq x l(-1). Massive intraperitoneal accumulation of diluted Gastrografin is a rational explanation for the rapidly developed hyponatremia, which can lead to hyponatremic encephalopathy, especially in infants. Prompt surgical intervention is therefore essential for successful management of such cases.
