Devices and methods for forming an anastomosis between two body lumens are described herein. In one embodiment, an anastomosis can be formed by transecting a body lumen using a linear surgical stapler that delivers a plurality of sealing adjuncts in combination with a plurality of surgical staples along a staple line, where the plurality of sealing adjuncts are coupled to one another by a suture. A circular surgical stapler can be used to create an anastomosis with a second body lumen across the staple line. Before actuating the circular stapler, the proximal and distal ends of the staple line can be drawn into a central lumen of the circular stapler using the suture extending between the plurality of sealing adjuncts such that the staple line is resected when the circular stapler is actuated.
