ABSTRACT
Malrotation can be associated with either duodenal web or duodenal atresia. Abdominal wall defects such as gastroschisis and omphalocele and diaphragmatic hernia are associated with some degree of malrotation or non-rotation, since the bowel never returned to the abdominal cavity. Mortality rate is 65% when more than 75% of the bowel is necrotic.Chylous ascites is seen in cases of chronic midgut volvulus, since there is venous and lymphatic congestion. Chronic midgut volvulus results in lymphatic and venous congestion. Acute midgut volvulus presents with sudden onset of bilious vomiting, hypovolaemia, blood per rectum and shock. Most patients present in the first month of life. The midgut volvulus has a typical corkscrew appearance. The typical finding on abdominal ultrasound is the inverted relation between the SMA and the SMV. The radiographic distinction between midgut volvulus and obstruction from peritoneal bands may be subtle.
