Table 4 Two-stage vs three-stage ileal pouch-anal anastomosis
Feature
Two-stage IPAA
Three-stage IPAA
Typical sequenceProctocolectomy + IPAA + diverting ileostomy → ileostomy closure Subtotal colectomy + end ileostomy → completion proctectomy + IPAA + DI → closure
Usual candidatesMedically optimized, lower-risk, stable patients Acute severe colitis, high-dose steroids, biologic rescue, malnutrition
Short-term morbidityComparable to 3-stage in modern series Comparable; offers safer route in very sick patients
Pouch failure/leakNo significant difference vs 3-stage No significant difference vs 2-stage
Quality of life after closureSimilar global and functional PROs between strategiesSimilar global and functional PROs
