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.
A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
Due to intestinal malrotation 4.4% of children with omphalocele will experience a midgut volvulus in the days, months, or years after surgery. Parents of children with omphalocele should seek immediate medical attention if their child displays signs and symptoms of an intestinal obstruction at any point in their childhood to avoid the ...
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 ...
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 ...
It was used to treat colon cancer or inflammation (proctosigmoiditis, proctitis, diverticulitis, volvulus, etc.). Currently, its use is limited to emergency surgery when immediate anastomosis is not possible, or more rarely it is used palliatively in patients with colorectal tumours.
