Where this comes from

Abstract

Stapled hemorrhoidectomy is gaining popularity worldwide. One problem that is often encountered is difficulty with insertion of the circular anal dilator because of very protuberant and fatty buttocks and a narrow interischial tuberosity distance. We describe a modification of this device for easier introduction in such patients.
