Which ostomy type is among the most common to develop hyperplasia/pseudoverrucous lesions?

• A. Ileostomies
• B. Jejunostomies
• C. Urostomies with alkaline urine
• D. Colostomies

Answer: (B)

Chronic irritation of the skin around a stoma from ongoing, caustic effluent drives the development of hyperplasia and pseudoverrucous lesions. Jejunostomy drainage is particularly irritant because it is a very enzyme-rich, highly moisture-laden intestinal output. The combination of persistent exposure and digestive enzymes in the jejunal effluent makes peristomal skin more prone to inflammatory overgrowth and verrucous changes, so jejunostomies are among the ostomy types with the highest risk. Ileostomies and colostomies also irritate the skin, but their effluent is less enzymatically harsh and often less moisture-dominant. Urostomies can cause irritation from urine, especially if alkaline or leaking, but overall the risk of PPPN is greatest with jejunostomy drainage due to its caustic, enzyme-rich content.
