What information should be included when describing an ostomy site in medical notes?

Ostomy Site Documentation in Medical Notes

When documenting an ostomy site, include the following essential elements: stoma type and configuration, anatomical location, stoma appearance (color, height, and viability), peristomal skin condition, appliance fit, and output characteristics. 1, 2

Core Documentation Elements

Stoma Type and Configuration

• Specify whether the ostomy is a colostomy or ileostomy, noting the anatomical segment used (e.g., sigmoid colostomy, end ileostomy from terminal ileum) 1
• Document the configuration as either end or loop, as this affects management and reversal planning 1
  • End stomas have a single opening with the proximal intestine brought through the abdominal wall 1
  • Loop stomas have two openings side by side within the same aperture, with the proximal end "Brooked" (dominant) 1
• Note if a mucus fistula is present as a separate stoma 1

Anatomical Location

• Record the precise abdominal quadrant and position (e.g., left lower quadrant, within rectus muscle) 1, 2
• Document the stoma's relationship to anatomical landmarks: distance from umbilicus, scars, skin folds, and bony prominences 1, 2
• Note whether the site was preoperatively marked by WOC nursing, as this correlates with reduced complications 1, 3, 2

Stoma Appearance (Critical for Detecting Complications)

• Color assessment is paramount:
  • Normal stomas are bright red and moist 4
  • Purple or dark discoloration is a medical emergency indicating ischemia requiring immediate surgical evaluation 4
  • Dark red or purple coloration suggests tissue compromise and warrants urgent reporting 4
• Height/projection: Document whether the stoma is appropriately budded (protruding), flush with skin, or retracted 5
  • Ileostomies should protrude to prevent skin contact with liquid effluent 1
  • Flush stomas predispose to leakage complications 1
• Viability: Note any signs of necrosis, bleeding, or edema 2, 4

Peristomal Skin Condition

• Assess for skin breakdown, which is the most frequent complication caused by effluent leakage from poorly fitting appliances 3, 2
• Document specific findings:
  • Erythema, induration, or inflammation 2
  • Excoriation or ulceration (25-34% incidence in early postoperative period) 6
  • Signs of allergic contact dermatitis or fungal infection 3
  • Presence of folliculitis or pyoderma gangrenosum 3
• Note any protective barriers in place (zinc oxide, barrier films, pastes) 2

Appliance Fit and Function

• Document the pouching system type and fit, noting if the opening is appropriately sized (should be one-eighth inch larger than the stoma) 2
• Record evidence of leakage, as this is the primary cause of peristomal skin damage 3, 2
• Note appliance change frequency (colostomy appliances typically every 6-7 days; ileostomy wafers every 4 days) 1

Output Characteristics

• Volume: Particularly critical for ileostomies, where output >1.5 L/day indicates high ostomy output requiring intervention 1
• Consistency:
  • Colostomy output is typically formed with once-daily bowel movements 1
  • Ileostomy output is liquid, requiring emptying 3-4 times daily 1
• Frequency of emptying required by the patient 1

Common Pitfalls to Avoid

• Never dismiss purple or dark stoma discoloration as normal variation—this represents ischemia and requires emergency surgical consultation 4
• Do not overlook flush or retracted stomas, as these significantly increase leakage risk and skin complications 1, 2
• Avoid documenting only "stoma intact" without specific descriptors, as this misses critical complications affecting patient quality of life and morbidity 1
• Remember that inadequate documentation of stoma location relative to skin folds and scars correlates with higher complication rates 1, 2

Special Considerations for High-Risk Patients

• Patients with diabetes, immunosuppression, malnutrition, or corticosteroid use require more detailed daily monitoring beyond the standard first postoperative week 2
• Document any delayed tract formation (may take up to 14 days instead of the typical 7 days in high-risk patients) 2
• Note the presence of ascites or other factors impairing wound healing, as these affect ostomy management 2
