Many methods, which have effectively reduced the number of patients requiring hospital admission, have been described for the outpatient treatment of hemorrhoids. However, complications have been reported, and the methods are often associated with unpleasant side effects. In 1977 Neiger et al. described a new method that used infrared coagulation, which produced minimal side effects. The authors have conducted a prospective, randomized trial to evaluate infrared coagulation compared with more traditional methods of treatment. The authors' results show that it may be more effective than injection sclerotherapy in treating non-prolapsing hemorrhoids and that it compares favorably with rubber band ligation in most prolapsing hemorrhoids. No complications occurred, and significantly fewer patients experienced pain after infrared coagulation (P = less than 0.001).
