Talk:Duodenum

I don't understand
I don't understand a word. What is this article about? -- JeLuF


 * It's part of the digestive system. I made a couple of changes; is it to clearer now? Vicki Rosenzweig

I removed the bit about Greek etymology:
 * it is derived from the Greek dodekadaktulon

which, although mentioned on certain web sites, is not borne out by the OED. The OED says that duodena means dozen (sc. fingers or inches). There may well be, or have been, a Greek word dodekadaktulon, but it is not the etymon of duodenum. --Heron


 * dodekadaktulon also appears to mean "twelve fingers." Perhaps this Greek word is the original, and it was translated into its Latin equivalent. --Reuben

btw: the duodenum is referred to be located in the retroperitoneum (secondary retroperitoneal) —Preceding unsigned comment added by 69.153.196.160 (talk • contribs) 03:20, 19 August 2005 (UTC)

The duodenum absolutely is retroperitoneal (except the first 2cm), so I changed it. I'm a little disgruntled by how this section is written. Moore's anatomy says it's 25cm long, and this is canon among surgeons (the duodenum, ureter and oesophagus all being 10 inches long). Richardcavell 18:45, 1 September 2005 (UTC)

Could anyone check this sentence: 'Áduodenum is the duodenum of the duodenum in the duodenum' above ==External links==. It makes no sense imho. —Preceding unsigned comment added by 62.166.60.20 (talk • contribs) 13:49, 1 June 2006 (UTC)

Removing single-length comment
Removed from the article: "...and is about 18 cm (7 in) long"  -- is this for an average northern european adult male? An average teenage Peloponnesian female? +sj +  06:42, 18 October 2005 (UTC)

What is the situation concerning plicae circularis. Are they occasionally present or absent as i have heard from sepearte sources? —Preceding unsigned comment added by 83.104.130.77 (talk • contribs) 10:51, 23 July 2006 (UTC)

Page needs expansion on what reactions take place here, enzymes used and where the enzymes came from (from someone better qualified then me) —Preceding unsigned comment added by 70.69.140.179 (talk • contribs) 08:55, 24 January 2007 (UTC)

Pronunciation
Is the stress put on the e or on the o? —The preceding unsigned comment was added by Orthografer (talk • contribs) 06:44, 18 April 2007 (UTC).


 * My teacher says doo-O-DEE-num, but I say du-OD-num. Dictionary.com says doo-uh-dee-nuhm and doo-od-nuhm.  Blind man   shady  05:21, 30 May 2007 (UTC)

Both pronunciations can be considered correct. — Preceding unsigned comment added by 67.232.173.26 (talk) 18:12, 27 January 2012 (UTC)

Swollen and inflamed duodenum
I was hospitalized with severe abdominal pain which lasted for several days, but gradually subsided, vomiting for the first few hours that it all began, diareha for days and during the second day blood appeared in the stool. I had a very low blood pressure the first day. Tests/scans, showed free floating blood inside and outside the intestines and the DUODENUM WAS SWOLLEN AND INFLAMED. Scopes two weeks later showed much improvement...mild pain continued occasionally, no ulsers; doctor said test showed it wasn't crohns, although crohns is in family history / my brother and my son. Doctors and all the tests were unable to make a diagnosis....only showed the symtoms. ANY SUSGESTIONS AS TO WHAT THIS COULD BE OR HOW I COULD FIND OUT???? Doctor said he did everytest he could think of and he consulted with others. Just thought I'd put a note here and see if someone might respomnd with an educated guess or suggestion. Thank you.24.20.56.168 (talk) 08:25, 9 February 2008 (UTC)
 * Pancreatitis, Gastrinomas, Pancreatic Cysts, Salmonella infection of the Gallbladder, Zollinger-Ellison syndrome, Congenital Malfomations (including Annular Pancreas or Duplication of the Duodenum), GALT Lymphoma, Ischemic Colitis, Celiac Sprue, Adenocarcinoma, Carcinoid, Small Cell Lung Cancer or Melanoma metastasis, atypical Tropic Sprue, Whipple's Disease, Ascariscis, Dieulafoy’s lesion, Angiodysplasia, IBD is on the differential (Crohns and Ulcerative Colitis) like you want, but is rarely in the small bowel, many, many, many other things. To hard to do a differential with your description. Not trying to diagnose anyway, just show that there are more than 4 bowel diseases, listen to your doctors, they're not going to make things up.

What happens when duodenum is removed?

Duodenum is important as the site of Brunner's Glands which neutralize the acid coming out of the stomach, and the outlet of the pancreas which adds stuff to digest fats, sugars, and protein. It is typically not removed in entirety. Check out the Rue-in-Y article for more information I guess.


 * haha, i can't believe that someone would actually ask wikipedia about his medical problems when a fucking doctor just won't tell him what he wants to hear. this guy is a complete retard. —Preceding unsigned comment added by 84.186.243.174 (talk • contribs) 22:01, 8 November 2008 (UTC)


 * Yeah... This isn't a House, M.D. episode where everything gets solved in an hour (including commercials). This is Wikipedia, it's not a medical guidebook or anything else. 24.184.187.236 (talk) 17:19, 9 November 2009 (UTC)


 * It amazes me how rude and unhelpful people around here can be. It is true that Wikipedia is an encyclopaedia - it doesn't give advice, and is certainly not a substitute for the opinion of a medical professional.  A talk page is also not a discussion forum for the topic in question.  Maybe next time you could explain that in kinder terms, and take a little pride in your contributions instead of hiding behind the relative anonymity of your IP address.  leevclarke (talk) 22:35, 6 April 2010 (UTC)

Section on Methotrexate
On 12 November 2008, User 207.62.208.2 added a block of text talking about Methotrexate and intestinal lesions. This section doesn't really flow right and clearly doesn't belong in the paragraph it was added to, nor in the section on the function of the duodenum. I'm not even sure if it belongs in this article at all. It looks as if it was copy-pasted from some other source, but Google come up empty (other than Wikipedia related hits). The user 207.62.208.2 seems to have been editing lots of medically related pages, and he has been warned a couple of times on his talk page. But I really don't have enough medical knowledge to evaluate anything about his contribution, other than reading it as a lay person.

For the time being, I have moved this contribution to a seperate section. Scott Roy Atwood (talk) 00:23, 10 December 2008 (UTC)

Duodenum and Type II Diabetes
"It is most likely that one of the digestive additives produced by the Duodenum on entry of food in to it (or a secondary product) is absorbed by the jejunum and ileum and spread into the body instead of passing through the digestive system. The presence of those chemicals causes the muscles to exhibit insulin resistance and ultimately Type 2 Diabetes. Identification of these chemicals may lead to a cure for Type 2 Diabetes."

This section does not seem to be grounded in correct anatomical knowledge and is misleading. First, the phrase digestive "additives" made by the duodenum is misleading; these "additives" are present during every feeding event. Second, even if said additives or the vague "secondary product" are absorbed at the jejunum or ileum, they do not bypass the digestive system as implied; rather, this is the purpose of the digestive system. Almost all substances absorbed in the small intestine (duodenum + jejunum + ileum) go to the hepatic portal system, through the liver where metabolism and many other things happen, and then to the rest of the body. However, the way this is written, it says that the duodenum adds things the digestive tract that then bypass the digestive tract and somehow cause diabetes. Wallball 7 (talk) 03:19, 22 January 2010 (UTC) Agreed. I would love to see the basis for this statement. It sounds rather far-fetched, but I've been surprised many times before. A peer reviewed reference is required. —Preceding unsigned comment added by Altimmons (talk • contribs) 02:13, 27 August 2010 (UTC)

Right or left
In the 3th part of the duodenum the article says: "The third (inferior/horizontal) part of the duodenum begins at the inferior duodenal flexure and passes transversely to the left, crossing the left ureter, left testicular/ovarian vessels..." I think it should be right ureter and right testiculr/ovarian vessels because the duodenum is on the right and then turns left crossing the right vessels, finally ending on the left part of the body. An Anatomy book in my bookshelf says the same, but i'm not an expert. This should be checked.--Miguelferig (talk) 18:26, 10 September 2012 (UTC)

Proposed merge with Duodenal cap
Too small -- CFCF  🍌 (email) 21:07, 6 October 2014 (UTC)
 * Support agree. Can easily be merged, benefitting readers and reducing needless fragmentation. --Tom (LT) (talk) 02:06, 24 October 2014 (UTC)

Accessory Organs Section
The entry under “accessory organs” does not cite any sources and is poorly written. I have no background in biology or anatomy, but if someone who does could look at it and try to fix it up, that would be neat. Thanks Blob401 (talk) 05:47, 22 February 2021 (UTC)

Pronunciation
I attempted to add IPA pronunciation of the term to the lead. However, it seems that there's two different ways that people generally pronounce it from the quick search that I did. Is one more valid than the other? I don't have a background in medicine or anatomy so I’m afraid I wouldn't know. OlliverWithDoubleL (talk) 08:45, 10 August 2023 (UTC)
