Which hole do I attach the pursestring to?
That depends on how much prolapse you want to resect. The detachable anvil design enables you to assess the amount of prolapse to be resected before it is captured in the instrument shell. After assessing the amount of prolapse necessary for resection, select the anchor point that would provide the right amount of tissue resection for the individual patient.
