Premature infants presenting to the neonatal intensive care unit at the Hospital for Sick Children with a surgical abdomen over a 5-year period were studied retrospectively to determine the factors leading to the diagnosis of malrotation with volvulus and necrotizing enterocolitis (NEC). Fifteen preterm infants (less than 37 weeks) were diagnosed as having volvulus, and 54 had surgically treated NEC. Those with NEC were more likely to be systematically ill with grossly bloody stools, abdominal tenderness, and thrombocytopenia (P less than .005). Bilious vomiting and bilious gastric residuals were the only hallmarks of volvulus (P less than .005). Although the radiographic findings of thickened bowel walls and intramural air were significantly related to NEC, the accuracy and interobserver reliability in diagnosing these features was variable as was the ability to distinguish NEC from volvulus or normal on plain abdominal radiographs. Volvulus is an important cause of surgical abdomen in the preterm infant and can be misdiagnosed as NEC. An unusual course or the presence of bilious vomiting in any patient thought to have NEC should alert the clinician to the possibility of this diagnosis.

The records of 54 pediatric patients with symptomatic malrotation of the intestine seen over a 15-year period from 1978 to 1992 were reviewed. Bilious vomiting and bloody stools were the two most common clinical presentations in neonates, while bilious vomiting, recurrent abdominal pain and failure to thrive were the most common symptoms after the newborn period. Obscure symptoms, usually of appreciable duration, were common in many patients beyond infancy. Upper gastrointestinal radiologic examination is the preferred and more accurate method of diagnosing malrotation as it has greater sensitivity than barium enema study. Laparotomy showed 24 cases with midgut volvulus. The incidence of midgut volvulus in symptomatic malrotation was 42.1% in the neonatal period, and 50% beyond the neonatal period. The majority of patients were treated by Ladd's operation. Massive gangrene of the small bowel due to volvulus was noted in five neonatal cases. Three patients subsequently died of this complication. Four patients developed a bowel obstruction secondary to adhesions, which was relieved by enterolysis. This study reiterates that newborns with symptomatic malrotation require emergency laparotomy in order to prevent catastrophic massive bowel resection.

Bilious vomiting in newborns is an urgent condition that requires the immediate involvement of a team of pediatric surgeons and neonatologists for perioperative management. However, initial detection, evaluation and treatment are often performed by nurses, family physicians and general pediatricians. Bilious vomiting, with or without abdominal distention, is an initial sign of intestinal obstruction in newborns. A naso- or orogastric tube should be placed immediately to decompress the stomach. Physical examination should be followed by plain abdominal films. Dilated bowel loops and air-fluid levels suggest surgical obstruction. Contrast radiography may be required. Duodenal atresia, midgut malrotation and volvulus, jejunoileal atresia, meconium ileus and necrotizing enterocolitis are the most common causes of neonatal intestinal obstruction.

Surgical emergencies can be missed easily in children, who are not always able to volunteer relevant information. Awareness of the entities discussed in this review might help the EP uncover subtle clues to early diagnoses that might not be initially apparent. Ill-appearing children who have abdominal pain and vomiting should be considered to have ischemic or necrotic bowel until proven otherwise. Possible diagnoses include volvulus, intussusception, and necrotizing enterocolitis. Bilious vomiting, especially in a young infant, should be considered to be an indication of a high bowel obstruction such as midgut volvulus, which warrants immediate surgical consultation. Significant rectal bleeding with abdominal pain can result from intussusception, volvulus, or an inflamed Meckel's diverticulum. Rectal bleeding with unstable vital signs can result from an upper GI bleed (eg, peptic ulcer disease). Painless rectal bleeding can result from a Meckel's diverticulum, polyps, arteriovenous malformation, or a tumor. Examination of the genitalia is imperative, especially in boys, to exclude the possibility of an incarcerated hernia or testicular torsion.

Three children presented with bilious vomiting due to malrotation at the age of 3, 5 and 12 years, respectively. They were treated surgically and recovered fully. In the period 1989-2002, 12 patients were operated for malrotation after the first year of life in the Emma Children's Hospital AMC, Amsterdam, the Netherlands. The mean age at operation was 5 years (range: 1-15). The most important symptoms were (bilious) vomiting and abdominal pain. Four patients had a history of bilious vomiting in the neonatal period. Nine patients had been previously admitted to a hospital with abdominal complaints. The most sensitive imaging technique was an upper gastrointestinal contrast study. Malrotation with intermittent volvulus can cause recurrent abdominal complaints and vomiting in children. Bilious vomiting is pathologic at any age and should lead to further investigations, preferably an upper gastrointestinal contrast study to exclude malrotation or other obstructions.

Midgut malrotation with volvulus is a life-threatening surgical emergency. Because the consequences of malrotation associated with midgut volvulus may be catastrophic, prompt diagnosis and treatment are required to prevent mortality and short-gut syndrome. Intestinal malrotation is usually observed in the neonatal period. Bilious vomiting and bloody stools are the two most common clinical presentations, but the patients exhibit often no abnormal physical findings on abdominal examination. Imaging techniques (Rx, US) of the upper gastrointestinal tract must be very accurate in order to diagnose volvulus but frequently they fail to identify this illness. If any doubt exists, refer with pediatric surgical support for consultation.

Bilious vomiting is often a presenting feature of upper intestinal obstruction in newborn. We present a case of intestinal obstruction in a newborn baby caused by abnormal vascular band arising from portal vein aneurysm in association with a midgut volvulus. Congenital anomalies of portovenous system are very rare, and it usually presents with portal hypertension in late infancy or childhood. In this particular child, the portal vein aneurysm contributed to intestinal obstruction due to both a failure of intestinal rotation and a mechanical band over the transverse colon.
