Hand-sewn vs stapled IPAA and pouch failure

What is known

• Meta-analysis concluded stapled anastomosis is superior, with a large reduction in ileal pouch failure versus hand-sewn with mucosectomy. ¹
• The type of anastomosis was also identified as a risk factor for pouchitis, though the authors note the significance of these findings remains uncertain. ¹
• No difference between stapled and hand-sewn groups in dysplasia or neoplasia was found. ¹
• Older comparative work (Ziv/Fazio) similarly reported stapled anastomoses were safer than hand-sewn in ulcerative colitis. ^2–4

What is unknown / caveats

• Comparison is stapled vs hand-sewn WITH mucosectomy. Failure difference may partly reflect mucosectomy rather than the suture technique alone
• Included studies are mostly observational; the meta-analysis rates several outcomes as low certainty
• The excerpts report a directional pouch-failure benefit for stapling but do not give the pooled effect size or confidence interval for pouch failure specifically.
