Scientists have discovered what they are calling a new human organ that exists in the digestive system. Named the mesentery, the organ was previously thought to consist of fragmented and disparate structures. <br/><br/>Researchers found, however, that it is one continuous organ and outlined evidence to classify it as such in a review published in The Lancet Gastroenterology & Hepatology. J. Calvin Coffey, a researcher Ireland, made the discovery. Researchers hope that the reclassification will aid better understanding and treatment of abdominal and digestive diseases. <br/><br/>A mighty membrane that twists and turns through the gut is starting the new year with a new classification: the structure, called the mesentery, has been upgraded to an organ. Scientists have known about the structure, which connects a person's small and large intestines to the abdominal wall and anchors them in place. By recognizing the anatomy and the structure of the mesentery, scientists can now focus on learning more about how the organ functions. <br/><br/>In addition, they can also learn about diseases associated with the mesentery. In addition to studying disease, researchers may also look to the mesentery for new approaches to surgery, fewer complications, faster patient recovery and lower overall costs.
