Fig. 3. Irving procedure. A. The tube is divided in the region of the ampullary-isthmic junction, and the ends of the suture are kept long for traction and for use in the subsequent steps of the procedure. B. Using blunt dissection, a tunnel is made within the substance of the uterine myometrium and the proximal tube is pulled into this chamber and sutured in place. C. The distal tube is then buried within the substance of the broad ligament. Additional sutures may be necessary to close the defect within the mesosalpinx and adjacent broad ligament as a result of the previous dissection.
