The Department of Colorectal Surgery is currently leading a national study investigating the circular stapled technique for hemorrhoids. This technique allows prolapsing hemorrhoids to be treated surgically, but with significantly less pain than the traditional excisional treatment.
The technique is performed using a circular purse-string suture positioned above the enlarged internal hemorrhoids. A stapler is placed transanally to perform a removal of the prolapsing tissue. Positive short-term results using the circular stapler are well-documented. Patients experience significantly less postoperative pain and a quicker return to work than after traditional surgery.
