Acute Pancreatitis

Inflammation of the pancreas -Results in autodigestion of the tissue •May be acute or chronic -Acute form is considered a medical emergency •Pancreas lacks a fibrous capsule -Destruction may progress into tissue surrounding the pancreas -Substances released by necrotic tissue lead to widespread inflammation •Hypovolemia and circulatory collapse may follow

Acute Pancreatitis

Acute Pancreatitis - Signs and Symptoms

Cholecystitis

Acute or chronic inflammation causing distention of the gallbladder - it is usually associated with a gallstone impacted in the cystic duct. •Accounts for 10%-25% of gall bladder surgery. •The acute form is most common in middle aged women. •The chronic form is prevalent among elderly people

Signs and Symptoms •Abdominal Pain, which may become localized to the lower right quadrant. (McBurney's point) Palpate McBurney's point •Rebound tenderness •Anorexia after onset •Nausea or vomiting •With Rupture: Pain, Tenderness, Spams, with brief cessation of abdominal pain.

Apenditicitis

Bile is produced in the liver and stored in the gall bladder for release into the duodenum. •One component of bile is bilirubin, a product of the breakdown of old or damaged red blood cells. •When red blood cells breakdown, unconjugated ( indirect ) bilirubin forms in the circulation. •The liver conjugates this bilirubin, thus producing conjugated bilirubin. •The conjugated bilirubin is secreted into the bile. •Jaundice occurs due to increased levels of conjugated or unconjugated

Bile metabolism and causes of jaundice

Most malignancies develop from adenomatous polyps. •Early diagnosis is essential. •Cancer occurs primarily in persons over 50. •Risk factors -Familial multiple polyposis -Long-term ulcerative colitis -Genetic factors -Environmental factors •Diet low in fiber

Chronic Gastritis

Chronic disease characterized by diffuse destruction and fibrotic regeneration of hepatic cells. •Mortality is high; many patients die within 5 years of onset •As cirrhosis progresses, complications may occur: these include ascites, portal hypertension, jaundice, bleeding , esophageal varices, acute GI bleed, liver failure. •Age alert: Malnurished persons over 50 with chronic alcoholism, 2x more common in men.

Cirrhosis

Progressive destruction of the liver •Causes -Alcoholic liver disease -Biliary cirrhosis •Associated with immune disorders -Postnecrotic cirrhosis •Linked with chronic hepatitis or long-term exposure to toxic materials -Metabolic •Usually caused by genetic metabolic storage disorders

Cirrhosis

Small tumorlike growth that projects from a mucous membrane surface. •Types include: polypoid adenomas, villous adenomas, •Most are benign: however; villous and hereditary polyps tend to become malignant •Age Alert: under 10- Juvenile Polyps characterized by recal bleeding. Villious type are most prevalent in men over 55

Complications Of Hiatal Hernia

AKA- regional enteritis- Inflammation in ANY part of the GI tract but usually the terminal ileum, extending through ALL layers of the intestinal wall, It may involve lymph nodes and the mesentery. •AGE ALERT: Adults- 20-40

Crohn's Disease

X-ray reveals gallstones if there is enough calcium to be radioopague, can also disclose porcelain gallbladder. Also Known as ( bag of Diamonds ) •Ultrasound can detect gallstones as small as 2mm •Blood chemistry may reveal elevated Alkaline phosphate

Diagnosis of gallstones

Digital rectal exam. Detects almost 15% of colorectal cancers •Fecal occult blood test can possibly show blood in stool •Barium enema studies can determine the location of lesions that are not normally detected manually or visually.

Diagnostic test results

Barium enema identifies polyps in the colon •Fecal blood test is positive : GUIAC Test •Blood studies may show decreased hemoglobin level and hematocrit •Scope of colon and rectal biobsy confirmation

Diagnostic test results Of colonic polyps

Upper GI series reveals diverticulosis of the esophagus and upper bowel •Barium enema reveals filling of diverticula, which confirms diagnosis •Biopsy reveals evidence of benign disease, ruling out cancer

Diagnostic test results Of diverticulosis

Scope allows visual examination of the lining of the esophagus to reveal the extent of the disease and confirm pathologic changes in the mucosa •Upper GI series may detect hiatal hernia as cause

Diagnostic test results of GERD

Hepititis profile- looking for specific viral antibodies •Blood chemisty testing •Serum bilirubin levels high, due to liver's inability to conjugate

Diagnostic testing and results

X-ray shows air shadow behind heart ina large hernia •Barium swallow can detect hiatal hernia and diaphragm abnormalities •Treatment: •Restrict activities that increase intra-abdominal pressure •Proton pump inhibitors •Diet modifications- small , frequent, bland meals, not eating 2 hours prior to lying down

Diagnostic tests and results Of Hiatal hernia

Liver biopsy- tissue destruction and fibrosis •Abdominal X-ray- enlarged liver, cysts, liver calcifications, and massive fluid accumulation •Esophagogastroduodenoscopy- bleeding esophageal varices, •Blood studies reveal elevated levels of liver enzymes, total serum bilirubin, and indirect bilirubin. ( conjugated, and unconjugated ) decreased serum albumin and protein, prolonged prothrombin time.

Diagnostic tests and results Of cirrhosis

Fecal occult blood test reveals minute amounts of blood •Small bowel x-ray show irregular mucosa, ulceration, and stiffening •Barium enema reveals string sign, ( segments of stricture separated by normal bowel) and possibly fissures and narrowing of bowel. •Scope reveals patchy areas of inflammation

Diagnostic tests and results Of crohn's disease

Form at gaps between muscle layers •Congenital weakness of wall may be a factor. •Weaker areas bulge when pressure increases. •Many cases are asymptomatic. •Diverticulitis stasis of material in diverticula leads to inflammation and infection. •Cramping, tenderness, nausea, vomiting •Slight fever and elevated white blood cell count •Treatment of diverticulitis •Antimicrobial drugs

Diverticular Disease

In diverticular disease, bulging pouches ( diverticula) in the GI wall push the mucosal lining through the surrounding muscle. •Although the common site for diverticula is in the sigmoid colon, they may develop anywhere, from the proximal end of the pharynx to the anus •Common sites include the duodenum, near the pancreatic border or ampulla of Vater, and the jejunum. •Diverticular disease of the ileum ( Merkel's diverticulum) is the most common congenital anomaly of the GI tract. •Diverticulosis- diverticula present but asymptomatic •Diverticulitis - inflammed diverticula, may cause potentially fatal obstruction , infection, or hemorrhage.

Diverticular disease

Control of gastric emptying is lost and gastric contents are "dumped" into the duodenum without complete digestion. •May follow gastric resection •Hyperosmolar chyme draws fluid from vascular compartment into intestine. -Intestinal distention -Increased intestinal motility -Decreased blood pressure → anxiety and syncope( обморок)

Dumping Syndrome

Occurs during or shortly after meals -Abdominal cramps, nausea, diarrhea •Hypoglycemia 2 to 3 hours after meal -High blood glucose levels in chyme stimulate increased insulin secretion → drop in blood glucose levels •May be resolved by dietary changes -Frequent small meals - high in protein, low in simple carbohydrates •Often resolves over time

Dumping Syndrome

Pathophysiology •With acute cases, inflammation of the gallbladder wall usually develops after a gall stone lodges in the cystic duct. •Gallstone usually develop when cholesterol or bile salt metabolism is abnormal •Changes in the composition of bile may cause gallstones •When gallstones block bile flow, the gallbladder becomes inflamed and distended. •Growth of bacteria, usually E. Coli may contribute to the inflammation and abscess formation .

Gallbladder

Gallstones vary in size and shape. •Form in bile ducts, gallbladder, or cystic duct •May consist of -Cholesterol or bile pigment -Mixed content with calcium salts •Small stones -May be silent and excreted in bile •Larger stones -Obstruct flow of bile in cystic or common bile ducts - causing severe pain, which is often referred to subscapular area

Gallbladder Disorders

Acute abdominal pain in the upper right hand quadrant that may radiate to the back, between the shoulders, or to the front of the chest; typically occurs after a fatty meal. •Colic •Nausea and vomiting •Chills, low-grade fever •Jaundice

Galledbladder disorder( gallstones)

Causes of cholecystisis

Gallstones Poor or absent blood flow to the gallbladder Abnormal metabolism of cholesterol and bile salts

Gastric mucosa is inflamed. •May be ulcerated and bleeding •May result from -Infection by microorganisms -Allergies to foods -Spicy or irritating foods -Excessive alcohol intake -Ingestion of aspirin or other NSAIDs -Ingestion of corrosive or toxic substances -Radiation or chemotherapy

Gastritis - Acute Gastritis

AKA: Heartburn. Backflow of gastric or dueodenal contents or both into the esophagus and past the lower esophageal sphincter, without associated belching or vomiting. •The reflux of gastric contents causes acute epigastric pain, usually after a meal. •The pain may radiate to the chest or arms •Occurs frequently in pregnant and obese persons, lying down after a meal may also contribute or exacerbate condition.

Gastroesophageal Reflux Disease

Inflammation of the liver that usually results from exposure to certain chemicals or drugs •Most patient recover from this illness, although a few develop fulminating hepatitis, hepatic failure, or cirrhosis •VIRAL HEPATITIS is a common infection, resulting in hepatic cell destruction, necrosis, and autolysis. •Hepatic cells usually regenerate with little or no residual damage

Hepatitis

A defect in the diaphragm that permits a portion of the stomach to pass through the diaphragmatic opening into the chest •Treatment can prevent complications

Hiatal Hernia

Food may lodge in pouch of the hernia -Causes inflammation of the mucosa -Reflux of food up the esophagus -May cause chronic esophagitis •Signs -Heartburn or pyrosis -Frequent belching -Increased discomfort when laying down -Substernal pain that may radiate to shoulder and jaw

Hiatal Hernia

Part of the stomach protrudes into the thoracic cavity. •Sliding hernia -More common type -Portion and part of stomach and gastroesophageal junction slide up above the diaphragm •Rolling or paraesophageal hernia -Part of the fundus of the stomach moves up through an enlarged or weak hiatus in the diaphragm and may become trapped.

Hiatal Hernia

Appendicitis

Inflammation and obstruction of the vermiform appendix. •With the advent of antibiotics , the incidence and the death rate of appendicitis have declined; if untreated, the disease is fatal •AGE ALERT: can occur at any age but the majority of cases occur between 11 and 20. Affects both sexes equally; however, between puberty and age 25, it is more prevalent in men.

Gases and fluids accumulate proximal to blockage, distending the intestine. •Increasingly strong contractions of proximal intestine -Effort to move contents along •Pressure increases in lumen. -More secretions enter the intestine. -Compression of veins in wall •Intestinal wall becomes edematous. •Prevention of absorption

Intestinal Obstruction

Intestinal distention leads to persistent vomiting. -Additional loss of fluid and electrolytes -Hypovolemia(decreased volume of circulating blood in the body.) can result. •Intestinal wall becomes ischemic and necrotic. -If obstruction is not removed, gangrene ensues. •Ischemia and necrosis → decreased innervation and cessation of peristalsis •Paralytic ileus occurs if it is not a cause to begin with.

Intestinal Obstruction

Lack of movement of intestinal contents through the intestine -More common in small intestine •Mechanical obstructions -Result from tumors, adhesions, hernias, other tangible obstructions •Functional or adynamic obstructions -Result from impairment of peristalsis •Spinal cord injury •Paralytic ileus due to toxins or electrolyte imbalance

Intestinal Obstruction

Obstruction of large intestine -Develops slowly with mild signs -Constipation -Mild abdominal pain, followed by abdominal distention -Anorexia, vomiting, more severe pain •Treatment -Treatment of underlying cause -Fluid and electrolyte replacement -Surgery and antimicrobial therapy

Intestinal Obstruction

Obstruction promotes rapid reproduction of intestinal bacteria. -Some produce endotoxins. -Affected wall becomes necrotic and more permeable. -Bacteria and toxins leak into peritoneal cavity (peritonitis) or into blood (bacteremia and septicemia). •Perforation of the necrotic segment may occur. -Generalized peritonitis and septic shock

Intestinal Obstruction

•Functional obstructions or paralytic ileus from -After abdominal surgery -Spinal shock following spinal cord injuries -Inflammation related to severe ischemia -Pancreatitis, peritonitis, infection in the abdominal cavity -Hypokalemia -Mesenteric thrombosis -Toxemia

Intestinal obstruction

casauses of appendicitis

Mucosal Ulceration •Fecal mass ( fecalith) •Stricture •Viral Infection •Neoplasm •Foreign body

Diverticulum

Outpouching (herniation) of the mucosa through the muscular layer of the colon

The initial event is Hepatic scarring or fibrosis •Hepatocyte function is impacted as the matrix chages •Fat-storing cells are believed to be the source of the extracellulary changes •Cellular changes produce bands of scar tissue and disrupt lobar structure: •Complications: Portal hypertension, esophageal varices, ascites(the accumulation of fluid in the peritoneal cavity, causing abdominal swelling.), liver failure, and death.

Pathophisiology of cirrhosis

Pathophysiology •Inflammation spreads slowly and progressively •Enlarged lymph nodes block lymph flow to submucosa, •Lymphatic obstruction leads to edema, fissures, and abscesses •Skip lesions- mucosal ulcerations, that are not continuous, like in ulcerative colitis •Thickening of bowel wall causes stenosis (сужение) •Complications: anal fistula, perineal abscess, fistulas to the bladder, vagina, or skin, intestinal obstruction, nutritional deficiencies, and peritonitis.

Pathophisiology of crohn's disease

Non-Viral- after exposure to heptotoxic substance, hepatic cells necros, scarring forms, Kupffer cell Hyperplasia, and infiltration by Mononuclear phagocytes occurs. •Can be drug induced- manifests 2 - 5 weeks after therapy. •Viral- Virus causes hepatocyte injury and death by either directly killing cell or through the inflammatory reponse. •Later direct antibody attacj against viral antigens causes further destruction of the infected cells. Edema and swelling lead to collapse of capillary beds , decreased blood flow, tissue hypoxia, scarring , and fibrosis. •Complications: chronic persistant hepatitis, chrrhoisi, heptic failure and death,

Pathophisiology of hepatitis

Colonic polyps are masses of tissue resulting from unrestrained cell growth in the upper epithelium that rise above the mucosal membrane and protrude into the GI tract. •They may be described by their appearance : pedunculated- attached to a stalk, of sessile- attached to the wall with broad base. •Complications: slow bleed, bowel obstruction, large rectal bleeding, intussusception, colorectal cancer.

Pathophisiology oh colnic polyps

Apenditicitis

Pathophysiology •Mucosal ulceration triggers inflammation, which temporarily obstructs the appendix. •This obstruction blocks mucus outflow. Pressure in the now distended appendix increases, and the appendix contracts. •Bacteria multiply, and inflammation and pressure continue to increase. •This restricts blood flow to the organ which causes severe abdominal pain. •Inflammation can lead to infection, clotting, and tissue decay.

Lower esophageal spinctor does not maintain enough pressure to close and prevent backflow or reflux. •Typically the sphincter relaxes after each swallow to allow food into the stomach, In GERD, the sphincter doesn't remain closed and stomach contents flow into the esophagus. •The high acidity of the stomach contents causes pain and irritation in the esophagus, and stricture or ulceration may occur: •Complications: Reflux esophagitis- esophageal stricture- esophageal ulcer- Metaplasia- normal squamous epithelium is replaced with columnar epithelium ( Barrett's esophagus)- Pulmonary problems with reflux

Pathophysiology Of Gastroesophageal Reflux Disease

Hernias typically result when an organ protrudes through an abnormal opening in the muscle wall of the cavity that surrounds it. •In Hiatal hernias, a portion of the stomach protrudes through the diaphragm. •Three types of hiatal hernia can occur: •Sliding •Paraesophageal ( rolling) •Mixed

Pathophysiology Of Hiatal Hernia

Most are due to H. pylori infection. •Occur most commonly in the proximal duodenum (duodenal ulcers) •Also found in the antrum of the stomach (gastric ulcers) •Development begins with breakdown of mucosal barrier. -Decreased mucosal defense -More common in gastric ulcer development -Increased acid secretion predominant factor in duodenal ulcers

Peptic Ulcer - Gastric and Duodenal Ulcers

Women twice as likely to develop stones -High cholesterol in bile -High cholesterol intake -Obesity -Multiparity -Use of oral contraceptives or estrogen supplements -Hemolytic anemia -Alcoholic cirrhosis -Biliary tract infection

Risk factors for gallstones

Anorexia, nausea and vomiting, diarrhea •Dull abdominal ache- due to swelling of the liver capsule •Respiratory problems -due to pleural effusion, impaired gas exchange •Hematologic- bleeding tendency, anemia, splenomegaly, portal hypertension •Skin-severe pruritus palmar erythema, extreme dryness •Hepatic- jaundice, heptomegaly, ascites, and edema of lower extremities.

Treatment of crohn's disease

Cholecystectomy •Lithotripsy(дробление) •Low fat diet •antibiotics

Treatment of gallstones

Decreased detoxification reactions, resulting in accumulation of toxic substances in the blood, which can lead to heptic pathology. •Decrease in gluconeogenesis, which can cause fasting hypoglycemia. •Decrease in protein production, increasing the risk of bleeding. •Failure of the liver to secrete conjugated bilirubin or failure to conjugate it, which can cause jaundice.

What would happen if the liver failed?

The heptic portal vein drains the gut's venous system, carrying absorbed nutrients to the liver. •The liver performs many metabolic functions •Provides glucose during fasting ( via gluconeogenesis and glycogenesis) •Detoxifies various substances, •Stores glycogen, produces bile, as well as various proteins and lipids.

liver function

Likeyl results from high intra-luminal pressure on an area of weakness in the GI wall where blood vessels enter. •Diet may contribute due to decreased fiber consumption reduces fecal residue, narrows luman, and leads to increased need of higher pressure for defecation. • In diverticulitis, undigested food and bacteria accumulate in the diverticular sac. This hard mass cuts off the blood supply to the thin walls of the sac, making them more susceptible to attack by colonic bacteria •Complications - rectal hemorrhage, fistulas, obstruction, perforation, abcess, peritonitis

pathophisiology of diverticular disease

Frequent small meals, avoidance of eating just prior to bed •Sitting up during and afer meals, sleeping with head elevated •Proton pump inhibitors •Avoidance of foods that irritate the sphincter; caffeine, mint, and chocolate

treatment Of GERD

Diverticulosis

•Asymptomatic diverticular disease
