The clear advantages of the modern methods for outpatient treatment of internal piles are that they are quick and relatively painless. Patients lose little if any time from work, the complications are minor, and the cure rates are high. Pain is minimal.
Patients may have a little spotting of blood for a few days and slightly more bleeding may occur after 10-14 days, when the eschar sloughs, but major bleeding do not occur as in the old style surgical approaches. No episodes of infection, death, or impotence have been reported with the newer methods. The failure rates are reported to be 1-5%, but all that is needed is further treatment.
Formal surgical intervention is still occasionally necessary, but patients dislike it because of the associated pain and morbidity. Modern treatment methods provide a prompt effective treatment in most cases.
