Does IPAA result in higher postoperative complication rates compared to total colectomy alone in patients with IBDU

What is known

- A pediatric IBD cohort found similar complication rates and postoperative courses for subtotal colectomy, pouch plus colectomy, and pouch-alone procedures. ¹ - In indeterminate colitis, pouch complication and pouch loss rates were only slightly higher than in ulcerative colitis, with no difference in functional outcome. ² - Long-term pouch outcomes in IBD unclassified/indeterminate colitis are reported as equivalent to ulcerative colitis. ³

What is unknown / caveats

- No retrieved study directly compares pouch vs total colectomy alone in IBD unclassified - Direct comparison largely drawn from a pediatric cohort and UC vs indeterminate colitis comparisons - The comparison you ask about is not directly addressed for IBD unclassified; available data compare pouch surgery across colitis subtypes or across surgical staging rather than pouch versus colectomy alone.
