Lower GI and Accessory System Alterations Yolanda Chandler, MSN,RN
Diarrhea • Increased frequency of BM • Increased amount of stool • Altered consistency • All acute diarrhea considered infectious until cause known • Viral • Bacterial • Parasitic
Diarrhea • Antidiarrheal Drugs • Demulcent • Soothes, coats, protects mucous membranes • Pepto-Bismol • Anticholinergic • Inhibits GI motility • Lomotil/Imodium • Antisecretory • Prolongs intestinal transit time • Sandostatin • Opiod • Decreases CNS stimulation of GI tract motility & secretion-directly inhibits GI motility • Paregoric
Fecal Incontinence • Involuntary passage of stool • Risk factors: • Constipation • Diarrhea • Obstetric trauma • Fecal impaction • Other • Prevention/tx may be managed by bowel training program
Constipation • Decrease in frequency of BM from pt. “normal” • Hard, difficult-to-pass stools • Decrease in stool volume • Retention of feces in rectum • Goals: • Increase intake of fiber/fluids • Increase physical activity • Have soft, formed stools • No complications
Constipation • Drug Therapy • Bulk forming • Metamucil • Stool softeners • Colace • Lubricants • Oil retention enema • Saline and osmotic solutions • MOM, GoLYTELY, Fleet enema • Stimulants • Cascara, Dulcolax • Selective chloride channel activator • Amitiza • Serotonin type 4 receptor partial agonist • Zelnorm
Irritable Bowel Syndrome • Intermittent & recurrent abd. pain and stool pattern irregularities-classified as: • IBS w/diarrhea • IBS w/constipation • IBS w/diarrhea & constipation
Irritable Bowel Syndrome • Management
Appendicitis • Most common causes • Obstruction of lumen by fecalith (accumulated feces) • Foreign bodies • Tumor of cecum or appendix • Intramural thickening from excessive growth of lymphoid tissue • Clinical manifestations • Persistent/continuous pain beginning in peri umbilical area eventually shifting to right lower quadrant (McBurney’s point) • Anorexia • Nausea/vomiting • Localized/rebound tenderness • Muscle guarding • May or may not have low grade fever • Rovsing’s sign
Appendicitis • Diagnostic Studies • Complete history/physical • WBC count • UA • *Ultrasound • *CT • Management • Appendectomy • Preoperative • Postoperative
Peritonitis • Etiology/pathophysiology • Clinical Manifestations • Abdominal pain-most common symptom • Tenderness over involved area-universal sign • Rebound tenderness • Muscle rigidity/Spasm • Lie still/shallow respirations • Abd distention/ascites • Fever 100-101 • Tachycardia • Tachypnea • N/V • Altered bowel habits
Peritonitis • Complications • Diagnostics • Management
Inflammatory Bowel Disease • Crohn’s Disease • Ulcerative Colitis
Inflammatory Bowel Disease-Crohn’s • Pathophysiology • Clinical Manifestations • Assessment/Diagnostic Findings • Complications
Inflammatory Bowel Disease-Ulcerative Colitis • Pathophysiology • Clinical Manifestations • Assessment/Diagnostic Findings • Complications
Inflammatory Bowel Disease • Management • Nutritional Therapy • Pharmacologic Therapy • Surgical Management
Intestinal Obstruction • May occur in small intestine/colon • May be partial/complete • Mechanical • Functional
Intestinal Obstruction • Small Bowel • Pathophysiology • Clinical Manifestations • Assessment/Diagnostic • Management
Intestinal Obstruction • Large Bowel • Pathophysiology • Manifestations • Assessment/diagnostic • Management
Polyps • Neoplastic • Non –neoplastic • Manifestations • Diagnosis
Colorectal Cancer • Pathophysiology • Manifestations • Assessment/Diagnostic Findings • Complications • Management
Ostomies • Ostomy • Surgical procedure that allows intestinal contents to pass from bowel through opening in skin on abdomen • Used when normal elimination route no longer possible • Described according to location and type • Ileostomy • ostomy in ileum • Sigmoid colostomy • ostomy in sigmoid colon • Transverse colostomy • ostomy in transverse colon, etc.
Ostomies • Major types • End stoma • Loop stoma • Double barreled ostomy
Ostomies • Ostomy surgery • Pre-op • Selection of op site • Assess • Physical • Psychological • Social • Cultural • Educational • Bowel prep • Prophylactic antibiotics • Post-op • Assess • Stoma /surrounding tissue/pouching system • Teach • Ostomy care
Ostomies • Colostomy care • Ascending/transverse colon • Semiliquid stools • Sigmoid/descending colon • Semiformed/formed stools • Dietary modifications to decrease gas/odor • Irrigations • Ileostomy care • Liquid stool • Stoma protrusion of 1-1.5 cm makes care easier • Pouch at all times • Always use skin barrier • Monitor for fluid/electrolyte imbalances • Increase fluid to 2-3Liters daily (include sports drinks) • Low fiber initially-reintroduce fiber gradually • Stoma may bleed easily
Ostomies • Adaptation to ostomy • Grief reaction • ADLs resumed 6-8 weeks-avoid heavy lifting • Sexual dysfunction • Pelvic surgery • Radiation • Chemo • Meds • Fatigue • Body image
Diverticular Disease • Pathophysiology • Clinical Manifestations • Assessment/Diagnostics • Complications • Management
Hernias • May be: • Reducible • Irreducible/incarcerated • Strangulated • Types
Hernias • Clinical Manifestations • Management
Conditions of Malabsorption • Pathophysiology • Clinical Manifestations • Assessment/Diagnostic • Management
Hemorrhoids • Dilated veins of anal canal • Rectal bleeding w/defecation-bright red • Pruritis • Prolapse • Pain • Burning
Hemorrhoids • Nursing Management
Anorectal Abscess • Collections of perianal pus • Secondary to: • Anal fissures • Trauma • Inflammatory Bowel disease • Immunosuppressive (AIDS) • Diagnosed by • Rectal exam • Surgical therapy • I&D • Possible packing • Teaching
Anal Fistula • Abnormal tunnel leading from anus or rectum • Complication of Crohn’s • Feces may enter fistula causing infection • Surgical Therapy
Pilonidal Sinus • Hairs penetrate into epithelium/SQ tissue • No symptoms unless infected • Abscess requires I&D • Pack wounds • Sitz baths
Jaundice • Yellowish discoloration of body tissues • Results when concentration of bilirubin in blood becomes abnormally increased • A symptom rather than a disease • Usually 1st detected in sclera and skin • Types • Hemolytic • Hepatocellular • Obstructive
