We discovered that 3D pouchography reliably identified staple lines [pouch body, anorectal circular and transverse, and tip of J], the relationship between staple lines, and variations in pouch morphology and pouch pathology.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Three-dimensional reconstruction of IPAA morphology is highly feasible using readily available technology. In our practice, we have found 3D pouchography to be an extremely useful adjunct to diagnose various mechanical pouch complications and improve planning for pouch salvage strategies. Given its ease of use and helpfulness in understanding the pouch structure and function, we have started to routinely integrate 3D pouchography into our clinical pouch referral practice. Further study is needed to formally assess the value of this technique to aid in the diagnosis of pouch pathology.<\/jats:p>\n
