The diagnosis of malrotation with subsequent volvulus of the intestine represents acute surgical emergencies.

. Malrotation can present as either acutely intermittently or asymptotically. Indeed all pediatric radiologists are expected to know how to perform and interpret an upper GI series when malrotation or midgut volvulus is suspected 2 3. Although the diagnosis of malrotation is often straightforward the imaging features in approximately 15 of upper GI tract examinations are equivocal and lead to a false-positive or false-negative interpretation.

When a child presents with bilious vomiting malrotation and volvulus should be suspected. It presents with duodenal obstruction and bile emesis. Malrotation can be complicated by volvulus a surgical emergency that can lead to bowel infarction if not promptly treated 3 4.

Normal rotation of the proximal duodenojejunal loop and the distal cecocolic loop takes place around the superior mesenteric artery SMA as the axis and is usually divided into. Diagnosis is often by fluoroscopy an abnormally positioned DJ flexure indicates malrotation and a corkscrew appearance indicates volvulus. Contrast Enema 80 of patients with malrotation demonstrate an abnormal position of the cecum 20 of infants with malrotation have a normal cecal position 15 of patients with normal rotation have a mobile cecum Does not show the volvulus as well as the upper GI.

An evaluation for malrotation is part of every upper gastrointestinal GI tract examination in pediatric patients particularly neonates and infants. Malrotation is a possible cause of volvulus of the midgut around its vascular axis. Midgut malrotation hereafter referred to as malrotation is a developmental rotation and fixation abnormality of the embryonic bowel resulting in a narrow mesenteric root attachment.

The patient underwent surgery and was diagnosed having right paraduodenal hernia RPH and midgut malrotation. Intestinal malrotation is congenital abnormal positioning of the bowel loops within the peritoneal cavity resulting in abnormal shortening of mesenteric root that is predisposed to midgut volvulus. The sensitivity ranges from 92 to 100.

Midgut volvulus is a congenitally-acquired pathology due to failure of normal intestin. Malrotation - narrow mesenteric root - volvulus - venous obstruction - continued arterial inflow - venous congestion - raised tissue pressure above blood pressure -.

LearningRadiology - Malrotation with a Midgut Volvulus Malrotation with a Midgut Volvulus Torsion of entire gut around superior mesenteric artery SMA due to a short mesenteric attachment of small intestine in malrotation Age o Usually neonate or young infant o Occasionally older child and adult Associated with in 20 o Duodenal atresia. Neonates and infants with persistent bilious vomiting should undergo diagnostic workup and preferably ultrasound as the first step. Abstract Midgut malrotation is a surgical emergency usually seen in the first weeks of life.

The advantages and limitations of plain films barium enema studies and gastrointestinal studies were reviewed in 77 patients with malrotation.

The right colic artery and vein curved arrow were displaced anteriorly by the entrapped cluster of bowel loop.

Normally the presentation occurs early in the neonatal period and childhood. Malrotation is defined as an abnormal rotation of the duodenum andor caecum around the SMA axis with variable fixation of the midgut to the retroperitoneum 1. The features of CT manifestation in 16 cases were as follows.

Roland Talanow MD PhD. Upper gastrointestinal GI series has been the preferred imaging modality to evaluate for malrotation and midgut volvulus for the last 50 years 2 3. National Center for Biotechnology Information.

Midgut volvulus is a congenitally-acquired pathology due to failure of normal intestin. 4-6 Previous reports have focused on identifying the whirlpool sign ie swirling of the mesenteric vessels in clockwise direction as the transducer is moved craniocaudally.
