The narrow mesentery predisposes some cases of malrotation to midgut volvulus, a twisting of the entire small bowel that can obstruct the mesenteric blood vessels leading to intestinal ischemia, necrosis, and death if not promptly treated. The fibrous Ladd's bands can constrict the duodenum, leading to intestinal obstruction.
Volvulus occurs most frequently in middle-aged and elderly men. [11] Volvulus can also arise as a rare complication in persons with redundant colon, a normal anatomic variation resulting in extra colonic loops. [12] Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract.
This clinically manifests as poor feeding and bilious vomiting in neonates. Screening can be performed with an upper GI series. The most severe complication of malrotation is midgut volvulus, in which the mesenteric base twists around the superior mesenteric artery, compromising intestinal perfusion, leading to bowel necrosis.
Note that the double bubble sign is typically pathologic however it is not specific for duodenal atresia and may indicate other pathologies such as annular pancreas or midgut volvulus. [9] A limited upper gastrointestinal series using barium contrast can be used to differentiate between duodenal atresia and midgut volvulus.
Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, and constipation.Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischemia or perforation from prolonged distension or ...

The midgut is the portion of the human embryo from which most of the intestines develop. After it bends around the superior mesenteric artery , it is called the "midgut loop". It comprises the portion of the alimentary canal from the end of the foregut at the opening of the bile duct to the hindgut , about two-thirds of the way through the ...
