The introduction of new techniques and technologies in medical science is both stimulating and controversial. This article is a review of the current status of two such advances. Since its first description, the so-called "stapled hemorrhoidectomy" has been gaining increasing popularity, at first in Asia and Europe, and more recently in the United States. It is obviously a misnomer, since no excision of hemorrhoidal tissue is undertaken in this procedure. It is probably the most significant change in the surgical treatment of hemorrhoids since the introduction of conventional hemorrhoidectomy. Patients routinely experience less postoperative pain and have excellent control of symptoms, with few serious complications in most series. Despite a relatively simple operative technique, the procedure still has specific steps and features that must be followed and mastered to help insure success. The use of fibrin glue for treatment of perianal fistulae has also been a controversial issue, thus it is seldom included in any algorithm as a therapeutic step for fistula-in-ano. The reported success rates of the treatment range from 0% to 100% owing to the heterogeneity of the clinical trials, treatment protocols, patients, etiologies, and types of fistulae. However, the benign nature, simplicity, negligible morbidity, and repeatability of the treatment, potentially makes fibrin glue an attractive first line treatment for perianal fistulae.
