  • Inflammatory Bowel Diseases (IBD) is characterized by repetitive episodes of inflammation of the gastrointestinal tract caused by an abnormal immune response to gut microflora.
  • IBD is more prevalent in North America & Europe than in Asia or Africa. They have no specific cause.
  • Types of Inflammatory Bowel Diseases
    • Ulcerative colitis: involves diffuse inflammation of the colonic mucosa. It affects the rectum (proctitis), sigmoid (proctosigmoiditis), or the entire colon into the cecum (pancolitis).
    • Crohn disease: results in transmural (entire wall - 4 walls) ulceration of any portion of the GIT most often affecting the terminal ileum & colon.
  • Crohn's Disease
    • non-caseating granulomas form involving all layers of the intestinal wall. It develops into the classic cobblestone mucosal appearances & skip lesions along the length of the intestine sparing areas with normal mucosa.
    • affect both the large & the small intestine
    • ulcerations & skipping lesions
  • Epidemiology of Crohn's Disease
    • strong link with tobacco use
    • adults: 20-40 years of age
    • Northern Europe & Jewish population (Ashkenazi Jewish)
  • Crohn's Disease has cobblestone mucosal appearances
  • Ulcerative Colitis
    It is an idiopathic inflammatory condition of the colon which results in diffuse friability (fissuring or splitting) & superficial erosions on the colonic wall associated with bleeding. It involves inflammation restricted to the mucosa & submucosa of the colon. Typically, the disease starts in the rectum & extends proximally in a continuous manner.
  • Ulcerative colitis is worse than Crohn's and affects the ENTIRE LENGTH of the colon. It has an absence of Haustra (LEAD PIPE APPEARANCE)
  • Epidemiology of Ulcerative Colitis
    • Ulcerative colitis has a greater prevalence in adults than Crohn's Dse
    • Ulcerative colitis is less prevalent in pediatric population than Crohn's disease
    • The main onset of UC peaks between 15 & 30 years
    • A second but smaller peak occurs between 50 and 70 years
  • Pathophysiology of Ulcerative Colitis
    The pathophysiology involves defects in the epithelial barrier, immune response, leukocyte recruitment, and microflora of the colon. The epithelial barrier has a defect in colonic mucin, and possibly tight junctions, leading to increased uptake of luminal antigens.
  • Severe Ulcerative colitis can have pseudopolyps
  • Endoscopic view of milder ulcerative colitis
  • Diagnostic Evaluation of Ulcerative Colitis
    • Flexible Proctosigmoidoscopy/Colonoscopy - Clear picture

    • Antiemetic agents (metoclopramide)
  • Nursing Diagnoses for Acute Pancreatitis
    • Acute pain related to inflammation, edema, distention of the pancreas, and peritoneal irritation
    • Ineffective breathing pattern related to severe pain, pulmonary infiltrates, pleural effusion, atelectasis, and elevated diaphragm
    • Imbalanced nutrition, less than body requirements, related to reduced food intake & increased metabolic demands
  • Nursing Management of Acute Pancreatitis
    • Initially place on NPO (food stimulates activity of pancreas & gall bladder)
    • Insertion of NGT (suctioning)
    • Diet modifications: low fat & low protein. AVOID: caffeine & alcohol

    • May place on semi-Fowler's position
    • Monitor serum glucose q4-6H
  • Chronic Pancreatitis
    An inflammatory disorder characterized by progressive anatomic and functional destruction of the pancreas. As cells are replaced by fibrous tissue with repeated attacks of pancreatitis, pressure within the pancreas increases. The result is mechanical obstruction of the pancreatic and common bile ducts & the duodenum.

  • Surgical Management of Chronic Pancreatitis
    • Pancreaticojejunostomy (also referred to as Roux-en-Y) with a side-to-side anastomosis or joining of the pancreatic duct to the jejunum allows drainage of the pancreatic secretions into the jejunum.
    • Whipple resection (pancreaticoduodenectomy) has been carried out to relieve the pain of chronic pancreatitis.

    • Position of comfort: fetal position or the knee chest
    • AVOID: alcohol & caffeine
  • Cholecystitis
    Inflammation of the gall bladder usually caused by a gallstone in the cystic duct (cholelithiasis). Acute cholecystitis may also result from poor or absent blood flow to the gall bladder (not enough WBC are reaching the area causing infiltration of bacteria).
