IRA
The IRA can be performed both as an open or laparoscopic procedure, of which the latter is more common and preferred in modern practice. The ileostomy is closed, and the neoterminal ileum is in most cases anastomosed to the tip of the rectal remnant in the abdomen using a circular transanal stapling device or in some cases a handsewn anastomosis will be performed. The reconstruction is rarely protected by a temporary diverting loop ileostomy.
