Abstract

A pyloroplasty/pylorectomy shield having a base member and a proximally extending shield member. The pyloroplasty/pylorectomy shield has attachment means for engagement with a circular stapler. The pyloroplasty/pylorectomy shield also has dilation means for progressively dilating a sphincter. The pyloroplasty/pylorectomy shield is used with a circular stapler to perform a pyloroplasty/pylorectomy. Also disclosed is a method of performing a pyloroplasty/pylorectomy using the pyloroplasty/pylorectomy shield of the present invention. The pyloroplasty/pylorectomy shield has numerous advantages including reduced trauma, decreased misalignment resulting in improved stapling and improved positioning of the pyloroplasty/pylorectomy.

Claims

1. A method of performing a pyloroplasty/pylorectomy, comprising:

inserting a circular stapler having a pyloroplasty/pylorectomy shield into the pylorus of a mammal; and

,

actuating the stapler so that a section of the pylorus is removed and adjoining tissue is stapled,

wherein the pyloroplasty/pylorectomy shield comprises;

a base member having a proximal end and a distal end;

anvil means mounted to the proximal end of said member;

attachment means mounted to said proximal end of said member for engagement with a circular stapler;

a pyloroplasty/pylorectomy shield member extending axially from the proximal end of said member; and

,

dilation means extending from the distal end of said member.
