Types of Anastomosis
End-to-end: Both ends joined directly. Used when bowel diameter is equal (ileum-ileum, colo-colic).
End-to-side: End of one to side of another. Used in biliary-enteric, gastrojejunostomy.
Side-to-side: Both sides joined. Used in enteroenterostomy, jejunojejunostomy.
Stapling vs Hand-Sewn
Stapling: Faster, more consistent, less tissue handling. Hand-sewn: More versatile, cheaper. Staplers preferred for ileal pouch-anal anastomosis.
