New organ discovered inside human belly

Irish researchers have confirmed that the mesentery — a fold of membrane that connects the intestine to the abdomen — is its own continuous organ, and not a series of fragmented parts like experts had previously thought, reports Yahoo News.

So, this week, as you dream up ways to improve yourself in 2017, give yourself a pat on the back: You've already made a significant change this year, from deep within your belly.

You technically gained an organ.

The discovery could create a new field of "mesenteric" science and may help doctors better understand and treat abdominal diseases, said Calvin Coffey, a professor of surgery at University of Limerick's Graduate Entry Medical School, according to the report in Yahoo News.

"We are now saying we have an organ in the body which hasn't been acknowledged as such to date," he said in a news release.

Coffey published his peer-reviewed findings in the November issue of The Lancet Gastroenterology & Hepatology, a top medical journal on the digestive system, reports Yahoo News quoting Mashable.

Mashable was unable to reach Coffey for comment by the time of publication.

An organ is considered to be a self-contained body part that serves a specific vital function. The heart, for instance, is a muscular organ that pumps blood through our blood vessels.

Researchers say they still don't quite understand the mesentery's key functions, beyond the obvious role as a connective layer, reports Yahoo News.

One of the world's earliest depictions of the mesentery was produced by the Italian Renaissance artist Leonardo da Vinci. While his drawing and subsequent medical illustrations showed the mesentery as a continuous structure, in the past century scientists came to believe it was a series of broken-up pieces, and thus less medically significant, according to the report.

In 2012, Coffey and his colleagues first showed through microscopic analyses that the fold of membrane was, in fact, a single connected structure, says the report.

Over the last four years, the team continued to collect evidence confirming the mesentery's classification as an organ, which culminated with the November paper.

The research prompted the publishers of Gray's Anatomy, one of the world's best-known medical textbooks, to update the entry for mesentery, reports Yahoo News.

Elsevier, which publishes both Gray's Anatomy and The Lancet journal, included the reclassification of mesentery in its 41st edition of Gray's, which came out September 2015, Mashable confirmed.

Coffey said that better understanding and further scientific study of the mesentery could result in less invasive abdominal surgeries, fewer complications and faster patient recovery, according to the report in Yahoo News.

"When we approach it like every other organ...we can categorize abdominal disease in terms of this organ," he said in the news release.

"This is relevant universally as it affects all of us," he added. "Up to now there was no such field as mesenteric science."
