Various implementations of the invention provide for a one-piece surgical stapling apparatus that includes a stapler head and an anvil head assembly. The anvil head assembly is tiltable between a tilted position and a transverse position, and anvil plates of the anvil head assembly are moveable about one or more hinges between a closed and an open position. When in the tilted and closed positions, the anvil assembly has a reduced footprint that allows the anvil assembly to be passed directly through a trocar and holes created in the bodily tissues, which eliminates the need for separate placement of the anvil head. At the site of the anastomosis, the anvil head assembly can be moved to the transverse and open positions, and the stapling head may be engaged to fire staples against the anvil head.
