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.
