CPD II: liver

here is the section in the GI notes on liver diagnosis that i missed when we were in the thick of the semester...

liver dysfunction can manifest in many different body systems: liver failure or cirrhosis might cause generalized fatigue / anorexia / weight loss. an infection or inflammation of the liver might cause a fever. bad breath might result from abnormal methionine metabolism in late cirrhosis. bilirubin backup can appear as jaundice, or even pruritis. increased serum lipids might lead to xanthomas and xanthelasmas. improper estrogen / androgen metabolism might result in gynecomastia and testicular atrophy, as well as spider telangiectasias.

fatty liver is a fairly common dysfunction of the liver that afflicts about 25-30% of the population. it results from abnormal accumulation of fat droplets within the liver, which can ultimately lead to fibrosis, scarring, and cirrhosis. it is not directly caused by fatty food intake- other risk factors include diabetes and alcoholism. clinically, it might present as liver enlargement and slight elevation of liver enzymes. if steatosis progresses to fibrosis (and if alcohol is not involved), then non alcoholic steatohepatitis develops. this is more likely to occur in middle aged, obese, diabetic women who are on hormone therapy such as synthetic estrogen. like simple fatty liver, it might present simply as an enlarged liver and slightly elevated liver enzymes with no other symptoms, or might present with increased BP, palmar erythema, muscle aches/fatigue, muddy sclera.

hepatitis is inflammation and necrosis of the liver and infectious hepatitis can occur in several different flavors, hep A through E mostly. these all present with similar symptoms, including flu like symptoms, jaundice, RUQ pain, and have similar stages of development which include a prodromal phase with generalized symptoms. each variant has a particular mode of transmission: A and E are mostly via fecal oral, or oral/anal sexual practices. B and D are via unprotected sex or contaminated syringes, and C is mainly from contaminated syringes. all forms might present with an enlarged, tender liver and may have splenomegaly as well. labs that might aid in diagnosis: high ALT / AST, bilirubin, low albumin / platelets, normal WBC.

prolonged acute hepatitis can result in chronic inflammation which might lead to chronic hepatitis, which can come in several varities: lobular, persistent, and active (most likely to lead to failure/cirrhosis). presentation can be similar to acute, or nonspecific, or lupoid like symptoms. lab findings might be similar, with high ALT / AST, bilirubin, prolonged PT, decreased albumin, hyperglobulinemia, and presence of ANA in lupoid presenting patients. diagnosis is by liver biopsy and differential should consider wilson's disease if serum copper is elevated.

fulminant hepatic failure is defined as a combination of acute liver failure and encephalopathy that develops in less than 8 months with no prior history of liver dysfunction. it can be caused by a number of factors such as viruses, fatty liver, ischemia, toxin buildup. it might develop into coma, hypoglycemia, cerebral or GI hemorrhage, renal insufficiency-- despite this, the long term prognosis is excellent.

cirrhosis of the liver occurs after longstanding injury or inflammation of the liver from a variety of causes and is a combination of fibrosis, necrosis, regeneration, ultimately resulting in hepatocyte shrinking. it is most commonly caused by hep C, then alcoholism, then hep B and cryptogenic causes. if it is due to alcohol, the liver might feel both enlarged and with a bumpy edge. cirrhosis can present with clubbing, dupuytren's contracture, fetor hepaticus, pleural effusion, and dilated abdominal veins. additionally, because of restricted blood flow, it results in portal hypertension and can cause ascites and esophageal varices.

cirrhosis predisposes to formation of liver cancer, hepatocellular carcinoma. HCC can also be related to chronic alcoholism, childhood hep B infection, hep C (especially in japan and europe), HBV, hemocromatosis. prognosis is not good; usually leads to death within 6-20 months. it presents similarly to advanced cirrhosis and lab markers such as transaminases, alk phos, bilirubin, LDH are elevated. alpha fetal protein is elevated in 75% of cases and is a good way to predict for HCC.

liver tumors can also be benign, as in the case of hepatic adenoma- which is most commonly seen in women in their 30's on birth control pills. they would present asymptomatically, or with hepatomegaly if the tumor was big enough, or with RUQ pain if ruptured (rare). once oral contraceptives are stopped, prognosis is good.

finally, gilbert's syndrome is an autosomal recessive disorder in which bile pigment clearance from the liver is impaired, resulting in elevated bilirubin levels without outright liver damage. it might be triggered by dehydration, stress, menses, viruses, fasting, and might only present with mild jaundice and vague symptoms like abdominal cramping and fatigue. diagnosis is by excluding hemolysis by testing for normal LDH and CBC reports, and liver tests to confirm that liver function is normal (except for unconjugated bilirubin).

CPD II: gall bladder disorders

this section in the GI lecture series went over the diagnosis of the various gall bladder pathologies; mainly biliary obstruction, acute cholelithiasis, and choledocholithiasis. gallstones are most commonly formed in older patients from high cholesterol levels, which causes the bile salts to precipitate out of solution. there biliary obstruction can cause pain that follows meals or wakes patients at night, plateaus for 3-4 hours, then subsides. it is a RUQ pain that often radiates around to the lower right scapula, and a positive Murphy's sign is helpful to diagnose gallbladder inflammation. imaging of the gallbladder via ultrasonography will show wall thickening and distention of the gall bladder, which should be monitored in patients periodically to determine efficacy of treatment. acute cholelithiasis presents as an unrelenting pain, mainly from the inflammation of the GB itself, as opposed to simply obstruction as in biliary obstruction. it can also be differentiated diagnostically by a low grade fever and a high WBC count. finally, choledocholithiasis is an obstruction of the common bile duct which may lead to cholangitis, obstructive jaundice, acute pancreatitis, and biliary pain.

CPD II: pancreatic cancer and pancreatic insufficiency

pancreatic cancer is a disorder that is difficult to manage because of its often delayed diagnosis and high potential for metastasis. it most commonly afflicts males, older than 55 years, and can be caused by smoking, alcohol, high animal fat diets, diabetes, and some forms of chronic pancreatitis. it might manifest vaguely at first, with epigastric tenderness, fatigue, nausea, weight loss. pain radiating from the abdomen to the back might indicate retroperitoneal invasion of the splanchnic plexus. pancreatic cancer can also be associated with migratory thrombophlebitis, upper GI bleeding, and diabetes mellitus.

patients with pancreatic cancer might present clinically with epigastric tenderness, signs of jaundice, and significant weight loss. late stage patients might present with ascites, a palpable abdominal mass, and hepatosplenomegaly. the diagnosis of pancreatic cancer might be aided by CEA or alpha FP levels, a chem screen for liver/kidney function, and trypsin levels. additionally, the tumor markers CEA and CA19-9 might be present. ultrasound, CT, biopsy and MRCP (a type of MRI used to visualize the pancreas) are all used to diagnose pancreatic cancer.

pancreatic insufficiency is a functional disorder, much like hypochlorhydria is for the stomach. it is thus difficult to diagnose, sometimes determined by excluding other diagnoses. it can be caused by overeating, excess carbohydrates, excess caffiene, lack of raw foods, and other dietary factors. it might result in indigestion, gas/bloating, low blood sugar, and a "left scapula reflex". the indican test, heidelberg test, and fecal chymotrypsin are used to diagnose, and a CBC shows macrocytic RBC's. treatment strategies are to improve food hygeine and supplement with enzymes.

CPD II: stool appearance and pancreatitis

the first part of this lecture focused on the diagnosis of different GI disorders based on stool appearance. ribbon shape might indicate spasm/IBS, uterus malposition or enlargement, compression from a mass. pencil shaped: spasm/IBS and stricture. floating stools: malabsorption, cystic fibrosis. small and hard: dehydration, low fiber, delayed tract time, hypochlorhydria. large and hard: dehydration, hypotonic bowel. difficult to pass: hemorrhoids, anal fissure, dehydration, hypotonic bowel. loose but not watery: mild intestinal irritation and malabsorption. alternating constipation and diarrhea: poor diet, parasites, IBS. offensive stool odor: dysbiosis or food decay. very dark stool: melena, upper GI bleeding. light brown, clay, green, or bright yellow colors: gallbladder issues (obstruction, excess secretion).

the next section in the GI lecture covered pancreatic disorders: acute and chronic pancreatitis. acute pancreatitis causes severe abdominal pain which can feel like a knife stuck in the LUQ and cause extreme limitation of movement and even breathing. it is most commonly caused by heavy alcoholism (pain develops over a few weeks) in men and by biliary tract disease or obstruction (pain develops suddenly) in women. other etiologies might include NSAID use or hypertriglyceridism.

the diagnosis of acute pancreatitis is made through the history/physical and a few useful lab tests. besides the knife like LUQ pain, patients might present with fever, hypoactive bowel sounds, jaundice, dyspnea (because any movement will worsen the pain). additionally, cullens and grey-turner signs might be positive, which indicate retroperitoneal hemorrhage from pancreatic autodigestion. the lab tests most helpful are amylase, lipase, CBC and a chem screen; serum amylase levels are elevated soon after the onset of pain and return back to normal 2-3 days afterwards whereas urine amylase elevates 7-10 afterwards. CBC might show elevated hematocrit and leukocytosis, while a chem screen might show hyperglycemia, hypocalcemia, and elevated bilirubin/AST/ALT. treatment of acute pancreatitis generally involves 100% pancreatic rest and pain management, although 10% of patients will die regardless of treatment. the remaining 90% might recover within 2-3 weeks.

chronic pancreatitis is also caused mainly by long term alcoholism, and can also be idiopathic, or hereditary, or due to hyperlipidemia, protein malnutrition, cystic fibrosis, or biliary obstruction. patients with chronic pancreatitis might remain asymptomatic for 62 months (81 months for alcoholics), then develop severe epigastric/LUQ pain that may radiate to the back in a band like fashion and come in 2-3 hour episodes. the pain might be relieved slightly by lying in the fetal position on the left side, in contrast to acute pancreatitis, the pain of which is generally not relieved by anything.

in contrast to acute pancreatitis, the physical might not be very useful for diagnosis, although fundoscopy might reveal milky white retinal blood vessels from hyperlipidemia, and an abdominal exam might reveal pseuodocysts, which are inflammatory masses. amylase and lipase levels are only slightly elevated- the more useful tests are serum trypsin, calcium, and TG levels, as well as the bentiromide test, which measures the excretion of PABA in the urine (decreased in pancreatic insufficiency). ultrasound, chest xray, and CT all show calcification in 30% of patients. pancreatic function can also be measured via direct tests, or stimulating the pancreas with a secretogogue and measuring pancreatic output in the duodenum or directly via cannulation.

CPD II: bowel disorders

polyps are fleshy outgrowths of the intestinal mucosa that can be categorized as hyperplastic, adenoma, or "polyposis" syndromes, each with their own unique etiologies and morphologies. hyperplastic polyps are most common, making up about 90% of epithelial polyps, and are less than 5mm in diameter. they are asymptomatic, found via endoscopy, and are generally considered benign. adenoma polyps are precancerous and make up 10% of epithelial polyps and are from 1.5-10mm (most are smaller and the larger ones have a greater potential to be cancerous). polyposis syndromes are inherited conditions that result in a multitude of intestinal polyps that have a high chance of progressing to adenocarcinoma. for example, nearly 100% of patients with familial polyposis syndrome have adenocarcinoma by age 40. gardner's syndrome is another polyposis syndrome with osteomas, soft tissue tumors, and sebaceous cysts. peutz-jeghers syndrome is yet another with mucocutaneous pigmentation and polyps in the form of harartomas in the GI tract.

adenocarcinoma is a cancer that can affect the GI tract that is the third most common cancer, after lung and breast / prostate. in males it more commonly affects the rectum and in females the colon. etiological factors include diet low in fiber and high in animal protein, prolonged transit time, rancid oils / fats, while protective factors can include selenium, vitamin C and E, carotene, antioxidants. most patients present asymptomatically, or have a positive occult blood test, but late stage adenocarcinoma can result in a variety of symptoms including weight loss, malaise, anorexia, jaundice, and ascites. if adenocarcinoma is in the right colon, the patient might be more prone to developing anemia symptoms, bleeding, and vague abdominal discomfort. if adenocarcinoma is in the left colon, patients might develop diarrhea / constipation, tenesmus, hematochezia / occult blood. finally, adenocarcinoma of the rectum will cause blood with each bowel movement. diagnosis is usually missed on PE, but aided by CBC, livery enzyme tests, carcinoembryonic antigen tests, as well as a colonoscopy and double contrast barium enema.

hemorrhoids are clusters of vascular, connective, or musclar tissue that affects the epithelium of the anal canal. they are precipitated by laxity of rectal muscles or pelvic congestion- not surprisingly, 1/3 of truck drivers suffer from hemorrhoids. if the hemorrhoid is in the anal canal, patients would likely present with painless rectal bleeding, but may also have perianal itching/irritation/pain, or more acute pain if the hemorrhoid is thrombosed. external hemorrhoids are more prone to thrombosis and thus more acute pain which is triggered by exertion, diarrhea, etc. and can last 1-2 weeks or until the thrombosis is resolved, after which a skin tag remains where the hemorrhoid once was.

anal fissures are acute tears in the anal mucosa most commonly from either constipation or diarrhea. fistulas are new tracts that open up from the anal canal to the perianal or ischiorectal area (recall that this was a complication of crohn's), associated with leukemia, diverticulitis, foreign body reactions, actinomycosis, and chlamydia. fissures and fistulas cause throbbing pain that occurs most of the day, worsened with pressure from sitting, or movement, and especially from bowel movements. the draining of a fistula, or the formation of a new fistula tract may spontaneously resolve the pain.

a couple more anorectal disorders: pruritis ani is intense itching of the perianal area, usually brought on by allergies, pinworms, or dermatological disorders. proctalgia fugax is episodes of intense rectal pain that lasts seconds to minutes, with no symptoms in between episodes. it is associated with MS, low fiber diets and IBS, and is treated with kegel exercises.

CPD II: GI malabsorption disorders

malabsorptive disorders of the intestine are categorized within this lecture into three categories: disorders related to insufficient digestive elements (such as lactase insufficiency), tropical sprue, celiac sprue. tropical sprue afflicts those who visit certain tropical countries and is thought to be related to infection by an unknown organism perhaps associated with an underlying nutritional deficiency. tropical sprue begins as foul, bulky stools characteristic of fat malabsorption, then progresses to systemic manifestations of malabsorption: weight loss, weakness, glossitis, stomatitis, cheilosis, hyperpigmentation, dry skin. a CBC might show megaloblastic anemia and a chem screen might show decreased levels of serum protein, calcium, phosphorous, cholesterol, prothrombin, HCl, but normal pancreatic function. decreased urine and serum levels in the D-xylose test is also used to diagnose tropical sprue.

gluten enteropathy is a general condition that involves a reactivity to gluten that afflicts up to 1/3 of the US population. of this subset, 5% have a more serious condition called celiacs which results in inflammation of the intestinal lining that leads to villous atrophy and malabsorption. traditionally a disease that afflicted young children, celiacs is now more commonly diagnosed in mid age adults- in particular those from western european, indian, south american, north african countries. there have been some hereditary factors identified such as certain allelles that are present in celiacs patients in the HLA-DQ2 and DQ1 genes, but for the most part the etiological mechanisms are unclear. celiacs patients might present with diarrhea / constipation, abdominal distention (in infants and children due to oncotic pressure changes resulting from low albumin levels), anemia / fatigue, hair loss, aphthous ulcers, dermatitis herpetiformis. lab tests of celiacs patients might show anemia of various types with an increased RDW, AST alkaline phosphatase with low albumin / plasma protein levels. other tests that can be performed are biopsy after gluten ingestion, and testing for IgA to gliadin, endomysial, tissue transglutaminase. two severe complications of celiacs that might arise are malignancy and osteoporosis.

the third major malabsorptive disorder that we learned about is lactase deficiency, the enzyme that digests lactose into glucose and galactose. this disorder is widespread and affects about 3/4 of the world's population, with a higher prevalence in native american, asian, and african american races. lactase deficiency can be congenital (very rare), primary (due to an inherent lack of production), or secondary (due to an acute illness or injury such as gastroenteritis or chemotherapy). it might result in a range of symptoms, from mild abdominal discomfort to severe diarrhea upon lactose ingestion. lactase deficiency is best diagnosed with the hydrogen breath test, which would measure abnormally high levels of hydrogen in the breath after ingestion of lactose. another method is simply to eliminate lactose from the diet and observe for change of symptoms.

CPD II: ischemic colitis, irritable bowel, appendicitis, diverticulitis

this lecture is a continuation of intestinal disorders, specifically focusing on inflammatory bowel diseases. ischemic colitis is the first disorder we covered, and is an inflammation of the mucosa and submucosa of the intestine that results either from insufficient perfusion (CHF) or an occlusive event (atherosclerosis), and accordingly is associated with elderly, smokers, and those who live sedentary lifestyles. acute cases, generally from occlusive events, present with sudden onset lower left abdominal pain, rectal bleeding, fever / hypotension, and peritoneal signs. chronic cases of ischemic colitis present with rectal bleeding as well, but have longer periods of vague abdominal pain, diarrhea, and generally a spared rectum, similar to crohn's. IC might present similar to diverticulitis or CA if there is frank blood.

irritable bowel syndrome is an extremely common disorder that contributes to 50% of all gastroenterologist visits. patients can be any age, and are more typically female. IBS can be the result of many different factors, and the exact etiological mechanism is unclear and oftentimes heavily influenced by emotional factors such as stress. other potential etiologies are: food allergy, abnormal transit profile, local histamine sensitization, epigenetics. diagnosis of IBS is made by the "rome III" criteria: lower abdominal pain for 3 days for 3 months in a row which is relieved by defecation and was accompanied at the onset by a change in stool frequency or appearance. diagnosis is also made by excluding "alarm signs" which might indicate a more serious, acute condition: onset after 50, severe diarrhea, nocturnal symptoms, severe weight loss, hematochezia, and positive family history for organic GI disease. the physical exam might be unremarkable, or reveal tenderness over the course of the colon. lab tests are generally only useful for excluding other diagnoses.

appendicitis is an inflammation of the appendix, which can be caused by fecaliths, lymphoid hyperplasia, parasites, and presents as epigastric pain that migrates to the right lower quadrant accompanied by weight loss and vomiting (which generally occurs after the onset of pain, as opposed to intestinal obstruction). there are a number of physical exam tests which can diagnose appendicitis with varying success, such as mcburney's, rovsing, obturator, cough, markle signs. a CBC might show WBC levels above 10,000 and neutrophilia above 75%.

diverticula present similarly to appendicitis in that they both cause localized lower abdominal pain-- but on opposite sides. diverticula are relatively common outpouchings of the colon caused by any factor that increases the intraluminal pressure of the colon, such as a low fiber diet or constipation. the sigmoid colon is particularly vulnerable to diverticula and thus typically pain is in the lower left quadrant of the abdomen.

while diverticula by themselves can be asymptomatic, inflammation and infection can result in diverticulitis, a more acute and serious condition which might even lead to perforation. patients with diverticulitis might have had a recent history of recurrent UTI's or pneumaturia, and present with severe LLQ pain, fever, altered bowel habits, and nausea/vomiting. complications of diverticula are manifold and can be detected by the symptoms that result: a vaginal fistula would result in feculent vaginal discharge. diffuse peritonitis would result in severe generalized abdominal pain. perforation would cause back or lower extremity pain, absent bowel sounds, and a high grade fever. lower GI bleeding might appear suddenly, be accompanied by an urge to defecate, and stop spontaneously. hemorrhoids or anal fissures might result in pain with defecation. diverticulitis is diagnosed by history, PE, and sigmoidoscopy imaging-- take note that barium xray should not be used in acute cases due to the danger of perforation.
