Chapter 4 โ Colorectal Cancer Risk Factors: Age/Family history/Genetic syndromes/Inflammatory bowel disease Surgical Procedures - Understand differences between: Low anterior resection/Abdominoperineal resection (APR)/Total colectomy/Proctocolectomy Common Exam Question Which surgery results in a permanent colostomy? Answer: APR
Chapters 5โ6: Inflammatory Bowel Disease
Crohn Disease Ulcerative Colitis
Any GI location Colon only
Skip lesions Continuous disease
Transmural Mucosal
Fistulas common Fistulas uncommon
Surgery not curative Surgery curative
Commonly tested: Surgical indications / J-pouch candidates / Ostomy creation indications
Chapters 7 & 9: Colostomy and Ileostomy Construction End Stoma: One lumen visible-Usually permanent Loop Stoma: Two openings-Usually temporary Double-Barrel Stoma: Proximal and distal limbs separated Loop-End Stoma Frequently appears in board-style questions.
High-Yield Stoma Assessment โ Always assess: Color: Normal: Red/Pink/Moist - Abnormal: Pale/Dusky/Black Height: Flush/Budded/Retracted Diameter: Measure regularly post-op Location: Within rectus muscle preferred Output: Expected varies by ostomy type.
Colostomy Output by Location: This appears repeatedly in WOCN testing.
Location Output
Ascending Liquid
Transverse Mushy
Descending Semi-formed
Sigmoid Formed
Ileostomy Output : Normal output characteristics/High-output definitions used in the curriculum/Risk factors for dehydration/Electrolyte loss patterns Major teaching point: Patients lose: Sodium/Water Most common complication: Dehydration
Urinary Diversions (Chapter 8) Ileal Conduit: Most common. Characteristics: Continuous urine drainage - Requires external pouch Continent Cutaneous Reservoir: Examples: Indiana pouch Characteristics: Catheterized reservoir Orthotopic Neobladder: Characteristics: Voids through urethra
PRIORITY #1: THINK LIKE A WOC NURSE For many questions ask yourself: What changed anatomically? - What are the consequences of that change? Example: Ileostomy Anatomy Change: Colon removed or bypassed Implications: Less water absorption/Less sodium absorption/Liquid output โ Dehydration risk
GOALS OF CARE QUESTIONS
What is the primary goal? Examples: Pre-op: Patient preparedness/Realistic expectations/Optimal stoma placement Post-op: Safe self-management/Skin protection/Prevention of complications Long-term: Independence/Quality of life/Social reintegration
LAR VS APR Low Anterior Resection (LAR) Usually: Rectal cancer / Sphincter preserved / Often requires: Temporary loop ileostomy - Why? To protect the distal anastomosis. Key Exam Point Loop ileostomy = diversion while anastomosis heals. Abdominoperineal Resection (APR) Removes: Rectum / Anal sphincter - Result: Permanent end colostomy Exam Clue If anus removed: โ Permanent colostomy WHEN A QUESTION DOESN'T SAY "LAR" OR "APR" Recognize surgery from description. Description: "Rectum removed but sphincter preserved" โ Answer: LAR Description "Rectum and anus removed" โ Answer: APR
LOOP ILEOSTOMY INDICATIONS Most common: Protect distal anastomosis - Especially: Low pelvic anastomosis/High leak risk-Usually temporary
ILEOSTOMY QUESTIONS - Specific UC Surgical Facts Ulcerative Colitis: Can be cured surgically. Common procedure: Total proctocolectomy with: End ileostomy OR IPAA (J-pouch) Crohn Disease Surgery is NOT curative.
DEHYDRATION -> Most tested ileostomy complication. Signs & Symptoms Early: Thirst/Dry mouth/Fatigue Moderate: Dizziness/Tachycardia/Decreased urine Severe: Hypotension/Acute kidney injury PREVENTION VS MANAGEMENT Prevention: Daily fluid goals/Electrolyte replacement/Monitor output/Increase sodium intake Management: Oral rehydration solution/IV fluids if severe/Evaluate medications/Evaluate output volume
HIGH OUTPUT ILEOSTOMY DISCHARGE PLAN Know discharge teaching. Monitor: Output volume/Urine output/Daily weight Call provider if: Output rises significantly/Urine decreases/Dizziness develops
BOWEL OBSTRUCTION QUESTIONS Partial Blockage: Symptoms: Cramping/Intermittent output/Abdominal distention Management: Warm fluids/Ambulation/Gentle abdominal massage Complete Blockage: Symptoms: No output/Severe pain/Significant distention/Nausea/vomiting Management: Immediate medical evaluation
PEDIATRIC DIVERSIONS
NEC: Necrotizing Enterocolitis - Most common diversion: Loop ileostomy โ Reason: Protect distal bowel/Allow healing Hirschsprung Disease - common diversion: Temporary colostomy โ Reason: Divert stool from aganglionic segment IMPERFORATE ANUS : High Defect - Greater risk: Continence problems/Higher lesion/Worse functional outcome Low Defect: Better continence potential INFANT POUCHING - Required: โSkin barrierโAppropriate pouching system Optional: Belt/Additional accessories Remember: Skin protection is a priority.
URINARY DIVERSIONS Permanent Urinary Diversion Indications Most common: Bladder cancer Also:Severe trauma/Neurogenic bladder/Congenital abnormalities
SURGICAL DRAIN QUESTIONS: These are frequently missed. Normal: Drain output gradually decreases. Concerning Finding: Drain output increases while stoma output decreases. Possible implication: Urinary leak/Anastomotic leakโRequires investigation
UTI QUESTIONS: Ileal Conduit: Early Signs: May be subtle: Fever/Malaise/Flank discomfort Later Signs: Chills/Pyelonephritis symptoms/Increased mucus/Cloudy urine UTI PREVENTION -> Promote: Adequate hydration/Complete drainage/Prevent urine stagnation Urine pH: Slightly acidic urine helps reduce bacterial growth. Know that hydration is the most important intervention.
ROD REMOVAL โ Loop ostomies often have a rod. Purpose: Prevent retraction. Removal: Typically: Around postoperative day 5โ
LAG TIME & GAS PRODUCTION Frequently tested. After surgery: Bowel activity returns gradually. Expected sequence: 1. Small bowel function 2. Gas production 3. Stool production (Gas often appears before stool)
COLOSTOMY WITH MUCOUS FISTULA : Indications: Distal bowel left in place. โ Need decompression or mucus drainage. Care: Mucus production is expected. A small pouch or dressing may be used. Do not mistake mucus for infection.
POUCHING PEARLS: Soft Abdomen - May need: Flexible barrier Firm Abdomen - May tolerate: More rigid barrier
Deep Crease - Consider: Convexity - Barrier rings
Skin-Level Os - Often needs: Convex pouching system
Visually Limited Patient: Select: Simple system/Larger closures/Easy-to-manage appliance.Goal: Promote independence.
