midgut

The GI neuroendocrine tumor is one of the most common indications causing liver metastases, especially when of midgut origin.

"Previously, the common understanding was that, when a mosquito has picked up a virus, it first needs some time to build up inside the midgut, or stomach, before infecting other tissues in the mosquito, but our observations show that this process occurs at a much faster pace; in fact, there is only a narrow window of 32 to 48 hours between the initial infection and the virus leaving the mosquito's stomach.

The major complication of Intestinal malrotation is midgut volvulus, which may result in mesenteric ischemia and if not immediately intervened, cause severe mortality and morbidity [1,2,3].

While this study focused on just one part of endoderm internalization, the hindgut, it is still unknown how the foregut, which forms the trachea, lungs, esophagus, stomach, and liver, and the midgut, which forms the pancreas and small intestine, are formed.

Because the appendix is located in an abnormal position there are two different anatomic anomalies attributed to a left-sided appendix: situs inversus and malrotation of the midgut loop.

Midgut volvulus is a rare type of malrotation that develops as a result of the rotation of the mesenteric root around the superior mesenteric artery (1).

The appendix develops from the midgut loop together with the caecum, ascending colon and the proximal two-thirds of the transverse colon.

He also reviewed the diagnosis and management of other abdominal surgical emergencies, including malrotation presenting with midgut volvulus, intussusception and infantile pyloric stenosis.

It has been reported that 40% to 80% of midgut carcinoid tumors spread to the mesentery.

Midgut volvulus can result in gangrene and loss of large segments of intestine.
