It primary causes ulceration in the large and small intestines but can occur anywhere in the gastro- intestinal (GI) tract from the mouth to the anus. Crohn’s Disease Etiology - is unknown Can occur as a result of an : immune response genes Crohn’s Disease Clinical manifestations Abdominal pain and cramping Diarrhea Fever Weight Loss Bloating Anal pain or drainage Rectal abscess Fissure Crohn’s Disease Investigations Stool test Blood test - Complete blood count (CBC). Colonoscopy Computed tomography (CT ) scans Barium X-rays Crohn’s Disease Management Pharmacologic agents - anti- inflamatory -Sulfasalazine, immune suppressors -Cyclosporin, and antibiotics - Metronidazole (Flagyl) Diet Surgery Crohn’s Disease Nursing management Assessment Problem identification Ulcerative colitis Ulcerative colitis is an inflammatory bowel disease (IBD) Ulcerative colitis usually affects only the innermost lining of your large intestine (colon) and rectum. It occurs only through continuous stretches of the colon, unlike Crohn's disease, which occurs anywhere in the digestive tract and often spreads deeply into the affected tissues. Ulcerative colitis Etiology Immune response - the immune system is activated only when the body is exposed to harmful invaders. Genetic Ulcerative colitis Clinical manifestation Abdominal pain Blood in the stool Ongoing bouts of diarrhea that don't respond to over-the-counter (OTC) medications Unexplained fever lasting more than a day or two Tenesmus (rectal pain) Weight loss Ulcerative colitis Investigations Blood tests – complete blood count Stool sample – the presence of white blood cells in your stool indicates an inflammatory disease, possibly ulcerative colitis. Colonoscopy -this exam allows for the viewing of the entire colon using a thin, flexible, lighted tube with an attached camera. Ulcerative colitis Flexible sigmoidoscopy - a slender, flexible, lighted tube to examine the sigmoid, the last portion of your colon. Barium enema. X-ray. CT scan  Ulcerative colitis Management Pharmacologic agent - Antibiotics Anti-diarrheals Pain relievers Anti-inflammatory drugs -Corticosteroids.

Acute appendicitis 2. Recurrent appendicitis 3. Chronic appendicitis Appendicitis Clinical manifestations Abdominal pain Loss of appetite Nausea and vomiting Constipation or diarrhea Inability to pass gas Low grade fever Abdominal distension Appendicitis Diagnosis History and physical examination Laboratory tests - WBC count and haemoglobin Ultrasound of the lower abdomen Abdominal computed tomography (CT scans) - may be used when symptoms are recurrent or prolonged. Appendicitis Management Surgery - Appendectomy Antibiotics are most effective when given preoperatively and they decrease post-op infections and abscess formation Appendicitis Nursing management Pre -operative – nil per os (NPO) status upon admission Administer IV fluids Semi-Fowler’s position to contain abdominal drainage in the lower abdomen Post-operative - Administer opioid analgesia (morphine sulfate) Administer intravenous (IV) antibiotics as ordered (surgical prophylaxis) Monitor naso-gastric (NG) tube drainage for perforation or abscess Monitor surgical drains. Peritonitis Peritonitis is an inflammation of the peritoneum (Brunner & Suddarth’s, 2008) Peritonitis Peritonitis can occur Spontaneous -this sort of peritonitis is the result of a liver as well as kidney malfunction Secondary- from an infection in the abdominal cavity Dialysis associated- is a chronic irritation of the peritoneum that occurs within individuals receive peritoneal dialysis. Peritonitis Types of peritonitis Primary spontaneous peritonitis - an infection that develops in the peritoneum Secondary peritonitis - which develops when an injury or infection in the abdominal cavity allow infectious organisms into the peritoneum. Peritonitis Signs and Symptoms Poor appetite Nausea Dull abdominal pain Fever Fluid in the abdomen Extreme thirst Anuric, or passing significantly less urine than usual Difficulty passing gas or having a bowel movement Vomiting Peritonitis Causes: Primary peritonitis - is usually caused by liver disease. Fluid builds up in the abdomen, creating an environment for bacteria to grow. Secondary peritonitis is caused by other conditions that allow bacteria, enzymes, or bile into the peritoneum from a hole or tear in the gastrointestinal or biliary tracts. Such tears can be caused by pancreatitis, a ruptured appendix, stomach ulcer, Crohn's disease, or diverticulitis. Peritonitis Investigations X-rays – to produce images of internal tissues, bones, and organs Laboratory tests (to identify the infectious organism) Exploratory surgery CT scans Peritonitis Management Pharmacologic agents Surgical intervention Nutrition and Dietary Supplements Diverticulitis Diverticulitis - is a small, bulging sacs or pouches of the inner lining of the intestine (diverticulosis) that become inflamed or infected. Most often, these pouches are in the large intestine (colon The cause of diverticulitis is unknown, but it is associated with a low-fiber diet, constipation, bacteria, and obesity. Diverticulitis Investigations Blood studies CT scan Ultrasound of the abdomen X-rays of the abdomen Diverticulitis Clinical manifestations Left lower quadrant pain Nausea and vomiting Constipation Diarrhea Flatulence Bloating. Diverticulitis Diagnostic investigations Blood studies- haemoglobin, white cell count, electrolytes A pregnancy test must be performed in any female of childbearing age who presents with abdominal pain to rule out ectopic pregnancy CT scans -can help assess disease severity, the presence of complications, and clinical staging. Diverticulitis Clinical manifestations cont. Abdominal x-ray Barium x-ray Diverticulitis Management Pharmacologic – antibiotics, analgesics Surgical – hartman procedure Collaborative care- dietician Diverticulitis Nursing Management Altered Comfort: Acute Pain r/t out pouching colon and stimulation of the diverticula during abdominal contraction Risk for Nutritional Imbalance: less than body requirement r/t impaired nutritional absorption secondary to disease process Interventions – administer analgesic, provide comfort, education, nutrition Stomas ostomy - surgical procedure that creates an artificial opening for the elimination of bodily wastes Types- 1. Colostomy- large intestine 2. Ileostomy – small intestine Stoma can be - temporary or permanent Diagram of a stoma Stomas Colostomy - is an artificial opening in the large intestine brought to the surface of the abdomen for the purpose of evacuating the bowel (Wells & Weller, 2004) Ileostomy- surgical procedure that creates an opening from the ileum through the abdominal wall to function as an anus Colostomy types Colostomy Reasons for Stoma formation To divert feces away from a surgical anastamosis, to allow healing Removal of or damage to sphincters which control continence To aid in symptom control where surgery is not possible Ostomies Indications Colostomy 1.

Disorders of Liver, Biliary tract and Pancreas Pancreas Pancreas - dual function -produces pancreatic fluid that breaks down all categories of food Pancreatic fluid is secreted into the duodenum Endocrine function – secretes, Insulin and Glucagons Liver Liver - largest internal organ Located on the right side of the body inferior the diaphragm Produces Bile (fat emulsifier) Connected to the gall bladder via the common hepatic duct Gall bladder Gall Bladder - sac found in hollow fossa of liver Stores bile from the liver by way of the cystic duct Bile is introduced into the duodenum in the presence of fatty food Gallstones can cause blockage to the gall bladder Hepatitis Hepatitis - is an inflammation of the liver, most commonly caused by a viral infection. There are five main hepatitis viruses, types A, B, C, D and E Disorders of the Liver, Biliary tract and Pancreas The disorders Hepatitis Cirrhosis Cholecystitis Cholelithiasis Pancreatitis Carcinoma of the pancreas Hepatitis Hepatitis A -this is caused by eating infected food or water. The food or water is infected with a virus called Hepatitis A Virus (HAV). Hepatitis B - this is an sexually transmitted disease (STD). It is caused by the virus HBV (Hepatitis B Virus) and is spread by contact with infected blood, semen, and some other body fluids. Hepatitis Hepatitis B cont. Using a syringe that was previously used by an infected person. Having your skin perforated with unsterilized needles, as might be the case when getting a tattoo. Hepatitis Hepatitis cont Sharing personal items, such as a toothbrush or razor, with an infected person. A baby can become infected through his mother's milk if she is infected. Hepatitis Hepatitis C - Hepatitis C is usually spread through direct contact with the blood of a person who has the disease. It is caused by the virus HCV (Hepatitis C Virus). Hepatitis D - only a person who is already infected with Hepatitis B can become infected with Hepatitis D. Hepatitis It is caused by the virus HDV (Hepatitis D Virus). Infection is through contact with infected blood, unprotected sex, perforation of the skin with infected needles. Hepatitis Hepatitis E - a person can become infected by drinking water that contains HEV (Hepatitis E Virus). Infection is also possible through anal-oral sex. Hepatitis Signs and Symptoms Diarrhea Fatigue Loss of appetite Mild fever Muscle or joint aches Nausea Slight abdominal pain Vomiting Dark urine Light colored feces Yellow skin Hepatitis Investigations History and physical examination Abdominal ultrasound Hepatitis virus serologies Liver function tests Liver biopsy to check for liver damage Paracentesis if fluid is in your abdomen Hepatitis Management - is dependent on the type Pharmacologic agents Education Cholecystitis Definition Cholecystitis is - defined as inflammation of the gallbladder that occurs most commonly because of an obstruction of the cystic duct from gallstones. Cholecystitis Causes Gallstones - in the majority of cases acute cholecystitis is caused by gallstones or biliary sludge getting trapped at the gallbladder's opening. Injury - trauma to the abdomen, or surgery, can result in cholecystitis. Cholecystitis Infection - if the infection is located within the bile, the gallbladder can become inflamed Tumor - a tumor may stop the bile from draining out of the gallbladder properly, resulting in an accumulation of bile, which can lead to cholecystitis. Cholecystitis Clinical manifestations Pain in your upper right abdomen that radiates to back and right shoulder blade. Nausea and vomiting. Tenderness in the right abdomen. Fever Cholecystitis Investigations History Examination Computed tomography (CT) Magnetic resonance imaging (MRI) Endoscopy. Cholecystitis Management Surgery to remove the gallbladder (cholecystectomy). Cholelithiasis Definition Cholilethiasis is the presence of gallstone in the gall bladder Cholelithiasis Sign and Symptoms Pain in the right upper or middle upper abdomen: Fever Yellowing of skin and whites of the eyes (jaundice) Clay-colored stools Nausea and vomiting Cholelithiasis Investigations Abdominal ultrasound Blood studies - complete blood cell (CBC) count with differential, liver function test, amylase and lipase.
