LEARNING OBJECTIVES
GENERAL: After the class student will be able to understand about the diagnostic tools and therapeutic measures.
SPECIFIC: Student will able to-• Enlist the diagnostic tools• Describe type of therapeutic intervention• Differentiate small and large intestine diagnostic measures.

INTRODUCTION
• Lower gastrointestinal disorders characterized by disease which occur in small and large intestines.
• The small and large intestines may be affected by infectious, autoimmune, physiological states& anatomical changes.• Inflammation of the intestines is called
enterocolitis e.g. ulcerative colitis, gastroenteritis.

CLASSIFICATION OF LOWER GI DISEASES
SMALL INTESTINE DISEASES• Gastroenteritis• Duodenal ulcer• Malabsorption• celiac disease• Intestinal obstruction• diarrhea

ASSESSMENT
• PATIENT HISTORY-past history-present history
• PHYSICAL EXAMINATION - observation - auscultation - Palpation - percussion

DIAGNOSTIC TOOLS
Lower GI assessment includes:• Lab test: e.g. stool test, blood test • Proctoscopy• Sigmoidoscopy• Endoscopic ultrasound• Capsule endoscopy• Colonoscopy• Barium enema• Gastric analysis e.g. pernicious anemia, ulcer and carcinoma

Proctoscope:
• It is a short, straight, rigid, hollow metal tube, usually has a small light bulb mounted at the end.
• Proctoscope is lubricated and inserted into the rectum, and then the obturator is removed, allowing an unobstructed view of the interior of the rectal cavity.

GASTROENTERITIS
DEFINITION: Gastroenteritis is an
inflammation of the mucosa of the digestive tract, mainly the stomach and intestine Acute gastroenteritis is defined as sudden diarrhea accompanied by nausea, vomiting and abdominal cramping.

EPIDEMIOLOGY
Can occur at all ages, but infants principal groupMore common in countries with poor hygiene standards, water sanitation problems It is estimated that three to five billion cases of gastroenteritis
resulting in 1.4 million deaths occur globally each year. Children and those in the developing world are most commonly affected.
As of 2011, in those below age five, there were about 1.7 billion cases resulting in 0.7 million deaths.
It is less common in adults, partly due to the development of immunity.

VIRUSES
Rotavirus is the most common cause of severe diarrhea among infants and young children.
Noroviruses are the most common cause of viral gastroenteritis in humans. The viruses are transmitted by fecally-contaminated food or water; by person-to-person

DIAGNOSTIC EVALUATION:• Stool
culture(pathogens, parasites, consistency, color& occult blood)• Blood profile (LFT,
triglycerides, CEA, AFP)• Electrolytes• skin turgor
![Page 50: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/50.jpg)

![Page 51: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/51.jpg)
PHARMACOLOGICAL THERAPY:Antiemetic's (Ondansetron, Metoclopramide)Antibiotic (azithromycin, Metronidazole, Vancomycin, Tinidazole)Antimotility agents (Loperamide, bismuth Subsalicylate)
![Page 52: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/52.jpg)
DIETARY MANAGEMENT:• high in simple sugar should be avoided• fermented milk products• zinc supplementation
NURSING MANAGEMENTNURSING GOALS:• management of diarrhea, acute pain, deficient fluid volume,
activity intolerance
![Page 53: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/53.jpg)

![Page 54: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/54.jpg)
NURSING DIAGNOSIS• Diarrhoea related to hyperactivity of intestine• Acute pain related to inflammation response• Deficient fluid volume related to excessive losses of body fluid
through diarrhoea• Activity intolerance related to weakness& abdominal pain• Imbalanced nutrition : less than body requirement due to
insufficient intake
![Page 55: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/55.jpg)
NURSING INTERVENTIONS:
• Assess general condition and vitals• Auscultate abdomen• Restrict solid food intake• Review factor that alleviate pain• Massage the area where pain is elicited if not contraindicated• Assess skin turgor and hydration• Maintain adequate hydration, increase fluid intake
![Page 56: introduction of lower GI disorders](https://reader035.fdocuments.us/reader035/viewer/2022062316/58ed994e1a28abc3118b45b5/html5/thumbnails/56.jpg)
