The DJJ can be mobile in children younger than 4 years, and displacement can occur in cases of gaseous distention of the stomach or bowel, as well as intra-abdominal processes that cause mass effect. Malrotation of the bowel causes shortening of the mesenteric root, which predisposes to volvulus. [17] If clinical suspicion is high, further evaluation should be undertaken with an upper GI series. Midgut volvulus is a surgical emergency at risk of bowel infarction. This life-threatening condition is a clear indication for emergent surgery. Sigmoidoscopy or a barium enema can be attempted as an initial treatment for sigmoid volvulus. Primary midgut volvulus cases diagnosed at adult ages constitute a rarity. The colon and small bowel are then free to swivel on the superior mesenteric axis; when they twist far enough, the bowel becomes obstructed. In normal rotation, the third portion of the duodenum (D3) lies between the superior mesenteric artery (SMA) and the aorta in the retroperitoneal space. Radiology. Iran J Radiol.

Diseases & Conditions, 2002 Radiographic diagnosis can be difficult in patients with intermittent or incomplete small bowel volvulus without malrotation. Normal radiographs are common with malrotation. The moderate-to-low degree of confidence associated with ultrasonography and CT necessitates an upper GI series to confirm the diagnosis.

This surgical emergency commonly masquerades as symptoms of pregnancy, which together with its low incidence often leads to delay in diagnosis and definitive treatment. Malrotation can present as either acutely, intermittently, or asymptotically. [2]. [18, 19] A normal variant that may be mistaken for swirling of the mesentery is the appearance of the proximal left jejunal veins as they course in a counterclockwise direction to join the superior mesenteric vein. It is a complication of malrotation. If the Malrotation and midgut volvulus is potentially one of the most serious pediatric surgical emergencies, and the role of radiology in its diagnosis is critical. Yousefzadeh DK.

Midgut malrotation is a congenital abnormality that, if complicated by volvulus, becomes a surgical emergency.1 2 Although asymptomatic malrotation may remain undiscovered, when symptomatic, 75% will present before the age of 5 years.3–5 Delayed diagnosis of midgut volvulus can lead to necrosis of the midgut, serious morbidity and mortality. Neonatal intestinal obstruction associated with situs inversus totalis: two case reports and a review of the literature.
