Gastrointestinal disorders

  1. GERD
    • backward flowing of gastric contents
    • avoid acidic foods and high fats or alcohol
    • stop smoking
    • eat small meals
    • maintain ideal weight

    managed with proton pump inhibitors, H2 receptor blockers, metoclopramide, antacids.
  2. Peptic ulcer disease PUD
    • a break in the mucous lining of the stomach, leading to ulcers, pain and bleeding.
    • Complications: Pain, gnawing, burning aching, can lead to anemia, blood in stool, perforation most lethal- leading to gastric contents in peritoneum leading to peritonitis. 

    Risk factor: H-pylori, smoking, NSAIDS, and stress.

    H-Pylori-releases enzymes that contribute to ulcers.
  3. Peritonitis
    life threatening acute inflammation of the visceral/ parietal lining and endothelial lining of the abdominal cavity. (high WBC count, paralytic ileus/absent bowel sounds, fever)

    body responds by shunting blood to the infected area. (This third spacing can lead to hypovolemic shock)

    • Assess lungs: for crackles, decreasing sats.
    • Assess electrolytes, H/H, I/O, vital signs and mentation.
  4. H-pylori treatment
    Treat H-pylori with two antibiotics and a proton pump inhibitor (clarithromycin, amoxicillin and protonix)  x 14 days
  5. Endoscopy for management of GI bleeds
    Endoscopy, with injection of a clotting or sclerosing agent into the bleeding vessel
  6. Appendicitis
    • simple gangrenous or perforated
    • symptoms: continuous, mild generalized pain, may intensify

    • low grade fever, nausea and vomiting
    • rebound tenderness at mcburneys point.
  7. roux-en-y procedure
    large portion of stomach and duodenum are bypassed
  8. Bowel obstruction/ intestinal obstruction
    Mechanical: physically blocked by lesion outside the bowel (adhesion), or inside due to chrons, tumors.

    Nonmechanical: paralytic ileus, decreased or absent peristalsis. 

    • These all can lead to edematous of the bowels. most commonly obstructions occur in small intestine
    • edematous bowel results in increased capillary permeability causing plasma to leak into the abdomen.
    • hypovolemia-electrolyte issues
    • High in the small intestine: leads to metabolic alkalosis. loss of gastric hydrochloride
    • low in the small intestine: leads to metabolic acidosis
  9. complications of obstructions? elderly bowel obstruction?
    • strangulated bowel: leading to interrupted blood flow.
    • Elderly: high risk for obstruction due to fecal impaction
    • Intussusception: telescoping of a segment of the intestine within itself.
    • Volvulus: twisting of the intestine.
    • Treatment: NG tube, frequent oral care, IV fluids w/ electrolytes, surgeons may use a laparoscopic approach. 

    Diagnostic: CT/ X-ray
  10. Ulcerative collitis
    • inflammation starts in the rectum and works its way up (Ulcers)
    • liquid bloody stools, nutritional deficiencies-genetic and autoimmune disorders are risk factors.

    • Diagnostic: colonoscopy
    • Lab: Decreased H/H, decreased Na, K and Chloride, elevated WBC’s
    • Treatments: Aminosalicylates/ Sulfasalazine (prostaglandin inhibitor), glucocorticoids, anti-diarrheal. Diet management, Surgery-colectomy
  11. Ulcerative colitis surgical procedures
    Total proctocolectomy with a permanent ileostomy-removal of colon, anus and rectum-ileum brought out into the abdominal wall. right lower ileostomy.

    Total colectomy with ileoanal anastomosis: 2 stage procedure- temporary ileostomy. after time to heal- it's reversed and stool is allowed to drain into the reservoir
  12. Crohns disease
    • inflammatory of small colon, transmural inflammation-thickened bowel wall.
    • fistulas can develop-intestine to intestine or intestine to bladder. severe malabsorption
    • genetic, environmental and immune factors are the cause. 
    • Management is similar to Ulcerative colitis
    • may need over 3k cals a day to maintain weight. surgical treatment is to remove inflamed areas of bowels.
  13. Diverticular disease
    • occur in small intestine or large
    • diverticulosis: abnormal  pouch like herniations in the wall of intestine. 
    • diverticulitis: infection present
    • Diverticula can perforate leading to infection or abscess- can cause bleeds.
    • May need antibiotic treatment

    Resection of large intestine

  17. pediatric GI disorders
    • Pyloric stenosis: obstruction of the circular muscle of pyloric canal
    • projectile vomiting 2-8 weeks after birth
    • pylorectomy performed.

    Hirschsprung disease: congenital absence of ganglion cells in the wall of rectum. Treatment is removal of this portion of bowel. Leads to difficulty passing stool.
  18. Cleft lip/ palate
    • maxillary process fails to form
    • occurs during first trimester 
    • treatment: multiple surgeries 
    • risk for aspirations

    treatments: prevent aspirations-safe feeding, adequate nutrition-breast feeding.
  19. Some risk factors for cleft lip
    Exposure to the drug phenytoin (Dilantin) during pregnancy is linked with a tenfold increase in the rate of cleft lip. Smoking while pregnant doubles the rate of cleft lip. Alcohol, anticonvulsants and retinoic acid (vitamin A) are linked with other birth malformations that include cleft lip and palate  we have seen a decrease with addition of folate to bread and cereal
  20. Celiac disease
    • immune mediated disorder of small intestine
    • Gluten sensitivity
    • inflammatory response of the small bowel
    • leads to atrophy of villi in small bowel and nutritional deficits
