What Is Adenocarcinoma Of Small Intestine?
A denocarcinomas are malignant tumors, or cancer, of the small bowel arising out of glandular tissue. They fall in the category of rare neoplasm, comprising only 3% of all gastrointestinal malignancies.
Primary adenocarcinoma is the most common histological (cell) subtype constituting 35–50% of cases.1
Q: What does adenocarcinoma look like?
A: Adenocarcinoma may manifest as strictures, nodules, excavating masses, or annular lesions.2

What Is Primary Sclerosing Cholangitis?
P rimary sclerosing cholangitis (PSC) is an uncommon, slowly progressive bile duct disease that results in stagnation or build-up of bile in the liver, called cholestasis.
Primary sclerosing cholangitis is characterized by sclerosis, or scarring inflammation in bile ducts both within the liver (intra-hepatic ducts), and outside the liver (extra-hepatic ducts), causing progressive narrowing and, eventually, obliteration of the bile ducts.
Primary sclerosing cholangitis comes under the umbrella term autoimune liver disease in which the end result is immune-mediated hepatocellular (liver cell) or hepatobiliary (bile duct) injury.1
Q:What happens when scarred bile ducts can no longer transport bile out of the liver?
A:Bile that cannot be removed from the liver by the biliary duct system backs up and damages the liver, causing cirrhosis.
Bile is continually made by the liver from phospholipids salt, cholesterol, and aging blood cells that it removes from circulation to be carried out of the liver. Bile also carries away waste products produced by normal metabolism and toxic substances that are removed by the liver for eventual elimination in stool. As such, bile must continually flow out of the liver to prevent build-up in the liver.
Bile is a greenish brown liquid made by the liver. Bile ducts carry it out of the liver to the gall bladder for storage until needed to aid in the digestion and absorption of fat from the small intestine. Bile emulsifies fat eaten in the diet so that the pancreatic enzyme called lypase can break it down into its fatty acid and glycerol components.
The liver is the largest organ within the body. It lies mostly in the upper part of the abdomen on the right side just under the diaphragm. About 70% of liver tissue is made up of cube shaped cells called hepatocytes that do the main work of the liver. Other cells (epithelial) form structure and are arranged in single layers around blood vessels, sinusoids, and bile ducts.
Build-up of bile in the liver is the end result of the inflammatory process in primary sclerosing cholangitis, that by swelling and scarring of bile ducts impedes and eventually prevents bile flow out of the liver, leading to liver failure. There is no curative treatment available for primary sclerosing cholangitis, besides liver transplantation.2
The appearance of the intrahepatic and extrahepatic biliary ducts can be assessed by use of cholangiography, and magnetic resonance (MR) imaging is the best way to identify patients. See image above.3
MR cholangiography offers a noninvasive method of obtaining images of the biliary system without the use of a contrast agent. There is no radiation exposure. Pulse sequences can be chosen to obtain bright bile or black bile cholangiograms. Image processing algorithms can be selected to obtain a three-dimensional representation of biliary anatomy and pathology, and those images can be rotated in any plane so that ductal anatomy and pathology can be seen to best advantage.4
There is no cure for primary sclerosing cholangitis but there are symptom treatments one of which is supplementation for low levels of vitamins A,D,E, and K. Liver transplant is the only effective option.

What Is Impaired Gall Bladder Motility?
I mpaired gall bladder motility means the gall bladder is slow to empty or is dysfunctional.
The functional disorder of the gallbladder is caused initially either by metabolic abnormalities or by an alteration in its muscular ability to contract (motility dysfunction).
The diagnostic criteria based on symptoms of motility dysfunction of the gallbladder are episodes of moderate to severe steady pain located in the epigastrium and right upper abdominal quadrant that last at least 30 minutes.
Gallbladder motility disorder is suspected after gallstones and other structural abnormalities have been excluded.1
Q: What does the gallbladder do?
A: The gallbladder is a small pouch-like organ about the size of a pear that receives bile produced by the liver and stores it until needed during digestion. It lies just under the liver.
Bile is a complex fluid containing water, electrolytes and many organic molecules including bile acids, cholesterol, phospholipids and bilirubin. Bile acids are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.2
Before a meal, the gallbladder is usually full of bile. In response to fat in the diet, the gallbladder squeezes stored bile into the small intestine through a series of ducts. When emptied after meals, the gallbladder is flat.

What Is Autoimmune Cholangitis?
A utoimmune cholangitis is a rare inflammatory self-targeted disease of the biliary tract produced by high levels of immunoglobulin G (IgG) antibodies and antinuclear antibodies (ANA).
Autoimmune cholangitis is characterized by progressive inflammation and scarring that leads to narrowing and destruction of the bile ducts and development of biliary cirrhosis of the liver.
Autoimmune cholangitis is also termed anti-mitochondrial antibody-negative primary biliary cirrhosis because there is no production of anti-mitochondrial antibodies.
Q: What happens when bile ducts can no longer transport bile out of the liver?
A:Bile that cannot be removed from the liver by the biliary tract backs up and damages the liver, causing cirrhosis. In Figure 1, bile back up would directly damage the hepatic (liver) cells seen here as grey “blocks.”
Bile is a greenish brown liquid continually made by the liver cells (hepatocytes) from phospholipids salt, cholesterol, and aging blood cells that it removes from circulation.
Bile also carries away waste products produced by normal metabolism and toxic substances that are removed by the liver for eventual elimination in stool.As such, bile must continually flow out of the liver to prevent build-up in the liver.
Bile from the hepatic cells drains into small tubes called canniculi and then into larger bile ducts to be carried out of the liver to the gall bladder for storage until needed to aid in the digestion and absorption of fat from the small intestine. Bile emulsifies fat eaten in the diet so that the pancreatic enzyme called lypase can break it down into its fatty acid and glycerol components.
Unfortunately, autoimmune cholangitis is difficult to diagnose because it mimics many other diseases such as primary sclerosing cholangitis, sarcoidosis, cancer and lymphoma.

What Are Esophageal Motor Abnormalities?
E sophageal motor abnormalities are disorders of the esophagus involving altered muscular motility characterized by impaired esophageal peristalsis, or the progressive wave-like movement that occurs automatically when food or fluids are swallowed.
Q: What is altered motility?
A: Altered motility describes the lack of coordinated muscular movements or weak muscular movement needed to rapidly propel food and fluids through the highly muscular esophagus from the throat to the stomach.
The esophagus is a tube-like organ that begins at the cricoid cartilage (Adam’s apple) as a continuation of the pharynx and ends at the lower esophageal sphincter (LES).
The LES is a very strong, circular muscle surrounding the junction of the esophagus and stomach. The LES opens to allow swallowed food and liquids to enter the stomach and closes to prevent their travelling back into the esophagus.
Failure of the lower esophageal sphincter to remain tightly closed after swallowing allows stomach contents to reenter the esophagus giving symptoms of heartburn.
On the other hand, failure of the LES to relax traps the contents of the esophagus so that it cannot quickly empty into the stomach as it should. Because the esophagus is not designed to hold food/fluids, the abnormal expansion results in pain, anxiety and possibly vomiting and choking. If the contents are aspirated into the windpipe upon choking, there will be coughing with attempts to clear it.

What Is Post-Cricoid Carcinoma?
P ost-cricoid carcinoma is a rare malignancy arising in the hypopharynx.
Q: What is the hypopharynx?
A: The hypopharynx is the lower portion of the pharynx that opens into the larynx. It is comprised of the postcricoid region, pyriform sinus, and posterior hypopharyngeal wall.
Tumors rarely appear in the posterior pharyngeal wall or postcricoid region without also involving the pyriform sinus. The lack of anatomic barriers between these sites and a propensity for these tumors to develop in the pyriform sinus and spread outward account for this phenomenon.
Overall prognosis for these tumors is poor. Because of the rich organic lymphatic and vascular networks, aggressive growth and early cervical metastases (compared with cancers at other head and neck sites) characterize these cancers.
A study investigating the clinical course of 21 patients with post-cricoid carcinoma found the 5-year cause-specific survival rate was 52%. All the patients who eventually died did so within 3 years of the treatment. Seven patients had distant metastases, representing a higher frequency as compared with that of patients with recurrence of the primary focus and cervical lymph node metastasis. All of these patients who had been treated by surgery died of the cancer.1
Unfortunately, hypopharyngeal cancers are discovered at a later stage than other head and neck cancers. The delay in diagnosis from symptom onset averages 10 months.2

B eefy, red, smooth, burning tongue is an inflammatory alteration in tongue tissue characteristic of vitamin B12 deficiency.
Inflammation makes the tongue red and sore which, when untreated, progresses to atrophied papillae (shrunken taste buds) that makes the tongue smooth.
Q: Why does vitamin B12 alter the tongue?
A: Vitamin B12 is essential for the metabolism of all cells, especially for those of the digestive tract of which the tongue is an organ.1
These easily seen changes to tongue tissue are an important diagnostic feature of deficient vitamin B12, which causes other devastating unseen damage, because the discomfort generally causes the individual to seek medical care.
